ide: remove the legacy ide driver

The legay ide driver has been replace with libata starting in 2003 and has been scheduled for removal for a while. Finally kill it off so that we can start cleaning up various bits of cruft it forced on the block layer. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Jens Axboe <axboe@kernel.dk>

-	  This is the generic IDE driver.  This driver attaches to the
-	  fixed legacy ports (e.g. on PCs 0x1f0/0x170, 0x1e8/0x168 and
-	  so on).  Please note that if this driver is built into the
-	  kernel or loaded before other ATA (IDE or libata) drivers
-	  and the controller is located at legacy ports, this driver
-	  may grab those ports and thus can prevent the controller
-	  specific driver from attaching.
-
-	  Also, currently, IDE generic doesn't allow IRQ sharing
-	  meaning that the IRQs it grabs won't be available to other
-	  controllers sharing those IRQs which usually makes drivers
-	  for those controllers fail.  Generally, it's not a good idea

-	help
-	  The CMD-Technologies CMD640 IDE chip is used on many common 486 and
-	  Pentium motherboards, usually in combination with a "Neptune" or
-	  "SiS" chipset. Unfortunately, it has a number of rather nasty
-	  design flaws that can cause severe data corruption under many common
-	  conditions. Say Y here to include code which tries to automatically
-	  detect and correct the problems under Linux. This option also
-	  enables access to the secondary IDE ports in some CMD640 based
-	  systems.
-
-	  This driver will work automatically in PCI based systems (most new
-	  systems have PCI slots). But if your system uses VESA local bus
-	  (VLB) instead of PCI, you must also supply a kernel boot parameter
-	  to enable the CMD640 bugfix/support: "cmd640.probe_vlb". (Try "man
-	  bootparam" or see the documentation of your boot loader about how to
-	  pass options to the kernel.)
-
-	  The CMD640 chip is also used on add-in cards by Acculogic, and on
-	  the "CSA-6400E PCI to IDE controller" that some people have. For

-	help
-	  Normally, IDE controllers built into the motherboard (on-board
-	  controllers) are assigned to ide0 and ide1 while those on add-in PCI

-	  Answering Y here will allow you to reverse the situation, with

-	  This can improve the usability of some boot managers such as lilo
-	  when booting from a drive on an off-board controller.
-

- * ALI M14xx chipset EIDE controller
- *
- * Works for ALI M1439/1443/1445/1487/1489 chipsets.
- *
- * Adapted from code developed by derekn@vw.ece.cmu.edu.  -ml
- * Derek's notes follow:
- *
- * I think the code should be pretty understandable,
- * but I'll be happy to (try to) answer questions.
- *
- * The critical part is in the setupDrive function.  The initRegisters
- * function doesn't seem to be necessary, but the DOS driver does it, so
- * I threw it in.
- *
- * I've only tested this on my system, which only has one disk.  I posted
- * it to comp.sys.linux.hardware, so maybe some other people will try it
- * out.
- *
- * Derek Noonburg  (derekn@ece.cmu.edu)
- * 95-sep-26
- *
- * Update 96-jul-13:
- *
- * I've since upgraded to two disks and a CD-ROM, with no trouble, and
- * I've also heard from several others who have used it successfully.
- * This driver appears to work with both the 1443/1445 and the 1487/1489
- * chipsets.  I've added support for PIO mode 4 for the 1487.  This
- * seems to work just fine on the 1443 also, although I'm not sure it's
- * advertised as supporting mode 4.  (I've been running a WDC AC21200 in
- * mode 4 for a while now with no trouble.)  -Derek

- *
- *  These chips are basically fucked by design, and getting this driver
- *  to work on every motherboard design that uses this screwed chip seems
- *  bloody well impossible.  However, we're still trying.
- *
- *  Version 0.97 worked for everybody.
- *
- *  User feedback is essential.  Many thanks to the beta test team:

- *
- *  Version 0.01	Initial version, hacked out of ide.c,
- *			and #include'd rather than compiled separately.
- *			This will get cleaned up in a subsequent release.
- *
- *  Version 0.02	Fixes for vlb initialization code, enable prefetch
- *			for versions 'B' and 'C' of chip by default,
- *			some code cleanup.
- *
- *  Version 0.03	Added reset of secondary interface,
- *			and black list for devices which are not compatible
- *			with prefetch mode. Separate function for setting
- *			prefetch is added, possibly it will be called some
- *			day from ioctl processing code.
- *
- *  Version 0.04	Now configs/compiles separate from ide.c
- *
- *  Version 0.05	Major rewrite of interface timing code.
- *			Added new function cmd640_set_mode to set PIO mode
- *			from ioctl call. New drives added to black list.
- *
- *  Version 0.06	More code cleanup. Prefetch is enabled only for
- *			detected hard drives, not included in prefetch
- *			black list.
- *
- *  Version 0.07	Changed to more conservative drive tuning policy.
- *			Unknown drives, which report PIO < 4 are set to
- *			(reported_PIO - 1) if it is supported, or to PIO0.
- *			List of known drives extended by info provided by
- *			CMD at their ftp site.
- *
- *  Version 0.08	Added autotune/noautotune support.
- *
- *  Version 0.09	Try to be smarter about 2nd port enabling.
- *  Version 0.10	Be nice and don't reset 2nd port.
- *  Version 0.11	Try to handle more weird situations.
- *
- *  Version 0.12	Lots of bug fixes from Laszlo Peter
- *			irq unmasking disabled for reliability.
- *			try to be even smarter about the second port.
- *			tidy up source code formatting.
- *  Version 0.13	permit irq unmasking again.
- *  Version 0.90	massive code cleanup, some bugs fixed.
- *			defaults all drives to PIO mode0, prefetch off.
- *			autotune is OFF by default, with compile time flag.
- *			prefetch can be turned OFF/ON using "hdparm -p8/-p9"
- *			 (requires hdparm-3.1 or newer)
- *  Version 0.91	first release to linux-kernel list.
- *  Version 0.92	move initial reg dump to separate callable function
- *			change "readahead" to "prefetch" to avoid confusion
- *  Version 0.95	respect original BIOS timings unless autotuning.
- *			tons of code cleanup and rearrangement.
- *			added CONFIG_BLK_DEV_CMD640_ENHANCED option
- *			prevent use of unmask when prefetch is on
- *  Version 0.96	prevent use of io_32bit when prefetch is off
- *  Version 0.97	fix VLB secondary interface for sjd@slip.net
- *			other minor tune-ups:  0.96 was very good.
- *  Version 0.98	ignore PCI version when disabled by BIOS
- *  Version 0.99	display setup/active/recovery clocks with PIO mode
- *  Version 1.00	Mmm.. cannot depend on PCMD_ENA in all systems
- *  Version 1.01	slow/fast devsel can be selected with "hdparm -p6/-p7"
- *			 ("fast" is necessary for 32bit I/O in some systems)
- *  Version 1.02	fix bug that resulted in slow "setup times"
- *			 (patch courtesy of Zoltan Hidvegi)

- * From: andy@cercle.cts.com (Dyan Wile)
- *
- * Below is a patch for DTC-2278 - alike software-programmable controllers
- * The code enables the secondary IDE controller and the PIO4 (3?) timings on
- * the primary (EIDE). You may probably have to enable the 32-bit support to
- * get the full speed. You better get the disk interrupts disabled ( hdparm -u0
- * /dev/hd.. ) for the drives connected to the EIDE interface. (I get my
- * filesystem  corrupted with -u1, but under heavy disk load only :-)
- *
- * This card is now forced to use the "serialize" feature,
- * and irq-unmasking is disallowed.  If io_32bit is enabled,
- * it must be done for BOTH drives on each interface.
- *
- * This code was written for the DTC2278E, but might work with any of these:
- *
- * DTC2278S has only a single IDE interface.
- * DTC2278D has two IDE interfaces and is otherwise identical to the S version.
- * DTC2278E also has serial ports and a printer port
- * DTC2278EB: has onboard BIOS, and "works like a charm" -- Kent Bradford <kent@theory.caltech.edu>
- *
- * There may be a fourth controller type. The S and D versions use the
- * Winbond chip, and I think the E version does also.

- * Thanks to HighPoint Technologies for their assistance, and hardware.
- * Special Thanks to Jon Burchmore in SanDiego for the deep pockets, his
- * donation of an ABit BP6 mainboard, processor, and memory acellerated
- * development and support.
- *
- *
- * HighPoint has its own drivers (open source except for the RAID part)
- * available from http://www.highpoint-tech.com/USA_new/service_support.htm 
- * This may be useful to anyone wanting to work on this driver, however  do not
- * trust  them too much since the code tends to become less and less meaningful
- * as the time passes... :-/
- *
- * Note that final HPT370 support was done by force extraction of GPL.
- *
- * - add function for getting/setting power status of drive
- * - the HPT370's state machine can get confused. reset it before each dma 
- *   xfer to prevent that from happening.
- * - reset state engine whenever we get an error.
- * - check for busmaster state at end of dma. 
- * - use new highpoint timings.
- * - detect bus speed using highpoint register.
- * - use pll if we don't have a clock table. added a 66MHz table that's
- *   just 2x the 33MHz table.
- * - removed turnaround. NOTE: we never want to switch between pll and
- *   pci clocks as the chip can glitch in those cases. the highpoint
- *   approved workaround slows everything down too much to be useful. in
- *   addition, we would have to serialize access to each chip.
- * 	Adrian Sun <a.sun@sun.com>
- *
- * add drive timings for 66MHz PCI bus,
- * fix ATA Cable signal detection, fix incorrect /proc info
- * add /proc display for per-drive PIO/DMA/UDMA mode and
- * per-channel ATA-33/66 Cable detect.
- * 	Duncan Laurie <void@sun.com>
- *
- * fixup /proc output for multiple controllers
- *	Tim Hockin <thockin@sun.com>
- *
- * On hpt366: 
- * Reset the hpt366 on error, reset on dma
- * Fix disabling Fast Interrupt hpt366.
- * 	Mike Waychison <crlf@sun.com>
- *
- * Added support for 372N clocking and clock switching. The 372N needs
- * different clocks on read/write. This requires overloading rw_disk and
- * other deeply crazy things. Thanks to <http://www.hoerstreich.de> for
- * keeping me sane. 
- *		Alan Cox <alan@lxorguk.ukuu.org.uk>
- *
- * - fix the clock turnaround code: it was writing to the wrong ports when
- *   called for the secondary channel, caching the current clock mode per-
- *   channel caused the cached register value to get out of sync with the
- *   actual one, the channels weren't serialized, the turnaround shouldn't
- *   be done on 66 MHz PCI bus
- * - disable UltraATA/100 for HPT370 by default as the 33 MHz clock being used
- *   does not allow for this speed anyway
- * - avoid touching disabled channels (e.g. HPT371/N are single channel chips,
- *   their primary channel is kind of virtual, it isn't tied to any pins)
- * - fix/remove bad/unused timing tables and use one set of tables for the whole
- *   HPT37x chip family; save space by introducing the separate transfer mode
- *   table in which the mode lookup is done
- * - use f_CNT value saved by  the HighPoint BIOS as reading it directly gives
- *   the wrong PCI frequency since DPLL has already been calibrated by BIOS;
- *   read it only from the function 0 of HPT374 chips
- * - fix the hotswap code:  it caused RESET- to glitch when tristating the bus,
- *   and for HPT36x the obsolete HDIO_TRISTATE_HWIF handler was called instead
- * - pass to init_chipset() handlers a copy of the IDE PCI device structure as
- *   they tamper with its fields
- * - pass  to the init_setup handlers a copy of the ide_pci_device_t structure
- *   since they may tamper with its fields
- * - prefix the driver startup messages with the real chip name
- * - claim the extra 240 bytes of I/O space for all chips
- * - optimize the UltraDMA filtering and the drive list lookup code
- * - use pci_get_slot() to get to the function 1 of HPT36x/374
- * - cache offset of the channel's misc. control registers (MCRs) being used
- *   throughout the driver
- * - only touch the relevant MCR when detecting the cable type on HPT374's
- *   function 1
- * - rename all the register related variables consistently
- * - move all the interrupt twiddling code from the speedproc handlers into
- *   init_hwif_hpt366(), also grouping all the DMA related code together there
- * - merge HPT36x/HPT37x speedproc handlers, fix PIO timing register mask and
- *   separate the UltraDMA and MWDMA masks there to avoid changing PIO timings
- *   when setting an UltraDMA mode
- * - fix hpt3xx_tune_drive() to set the PIO mode requested, not always select
- *   the best possible one
- * - clean up DMA timeout handling for HPT370
- * - switch to using the enumeration type to differ between the numerous chip
- *   variants, matching PCI device/revision ID with the chip type early, at the
- *   init_setup stage
- * - extend the hpt_info structure to hold the DPLL and PCI clock frequencies,
- *   stop duplicating it for each channel by storing the pointer in the pci_dev
- *   structure: first, at the init_setup stage, point it to a static "template"
- *   with only the chip type and its specific base DPLL frequency, the highest
- *   UltraDMA mode, and the chip settings table pointer filled,  then, at the
- *   init_chipset stage, allocate per-chip instance  and fill it with the rest
- *   of the necessary information
- * - get rid of the constant thresholds in the HPT37x PCI clock detection code,
- *   switch  to calculating  PCI clock frequency based on the chip's base DPLL
- *   frequency
- * - switch to using the  DPLL clock and enable UltraATA/133 mode by default on
- *   anything  newer than HPT370/A (except HPT374 that is not capable of this
- *   mode according to the manual)
- * - fold PCI clock detection and DPLL setup code into init_chipset_hpt366(),
- *   also fixing the interchanged 25/40 MHz PCI clock cases for HPT36x chips;
- *   unify HPT36x/37x timing setup code and the speedproc handlers by joining
- *   the register setting lists into the table indexed by the clock selected
- * - set the correct hwif->ultra_mask for each individual chip
- * - add Ultra and MW DMA mode filtering for the HPT37[24] based SATA cards
- * - stop resetting HPT370's state machine before each DMA transfer as that has
- *   caused more harm than good

- * ht6560b Timing values:
- *
- * I reviewed some assembler source listings of htide drivers and found
- * out how they setup those cycle time interfacing values, as they at Holtek
- * call them. IDESETUP.COM that is supplied with the drivers figures out
- * optimal values and fetches those values to drivers. I found out that
- * they use Select register to fetch timings to the ide board right after
- * interface switching. After that it was quite easy to add code to
- * ht6560b.c.
- *
- * IDESETUP.COM gave me values 0x24, 0x45, 0xaa, 0xff that worked fine
- * for hda and hdc. But hdb needed higher values to work, so I guess
- * that sometimes it is necessary to give higher value than IDESETUP
- * gives.   [see cmd640.c for an extreme example of this. -ml]
- *
- * Perhaps I should explain something about these timing values:
- * The higher nibble of value is the Recovery Time  (rt) and the lower nibble
- * of the value is the Active Time  (at). Minimum value 2 is the fastest and
- * the maximum value 15 is the slowest. Default values should be 15 for both.
- * So 0x24 means 2 for rt and 4 for at. Each of the drives should have
- * both values, and IDESETUP gives automatically rt=15 st=15 for CDROMs or
- * similar. If value is too small there will be all sorts of failures.
- *
- * Timing byte consists of
- *	High nibble:  Recovery Cycle Time  (rt)
- *	     The valid values range from 2 to 15. The default is 15.
- *
- *	Low nibble:   Active Cycle Time	   (at)
- *	     The valid values range from 2 to 15. The default is 15.
- *
- * You can obtain optimized timing values by running Holtek IDESETUP.COM
- * for DOS. DOS drivers get their timing values from command line, where
- * the first value is the Recovery Time and the second value is the
- * Active Time for each drive. Smaller value gives higher speed.
- * In case of failures you should probably fall back to a higher value.

- * Polling for DSC (a single bit in the status register) is a very important

- *
- * 1. Before a read/write packet command, to ensure that we can transfer data
- * from/to the tape's data buffers, without causing an actual media access.
- * In case the tape is not ready yet, we take out our request from the device
- * request queue, so that ide.c could service requests from the other device
- * on the same interface in the meantime.
- *
- * 2. After the successful initialization of a "media access packet command",
- * which is a command that can take a long time to complete (the interval can
- * range from several seconds to even an hour). Again, we postpone our request
- * in the middle to free the bus for the other device. The polling frequency
- * here should be lower than the read/write frequency since those media access
- * commands are slow. We start from a "fast" frequency - IDETAPE_DSC_MA_FAST
- * (1 second), and if we don't receive DSC after IDETAPE_DSC_MA_THRESHOLD
- * (5 min), we switch it to a lower frequency - IDETAPE_DSC_MA_SLOW (1 min).
- *
- * We also set a timeout for the timer, in case something goes wrong. The
- * timeout should be longer then the maximum execution time of a tape operation.

- * Packet Command Interface

- *
- * The handling will be done in three stages:
- *
- * 1. ide_tape_issue_pc will send the packet command to the drive, and will set
- * the interrupt handler to ide_pc_intr.
- *
- * 2. On each interrupt, ide_pc_intr will be called. This step will be
- * repeated until the device signals us that no more interrupts will be issued.
- *
- * 3. ATAPI Tape media access commands have immediate status with a delayed
- * process. In case of a successful initiation of a media access packet command,
- * the DSC bit will be set when the actual execution of the command is finished.
- * Since the tape drive will not issue an interrupt, we have to poll for this
- * event. In this case, we define the request as "low priority request" by
- * setting rq_status to IDETAPE_RQ_POSTPONED, set a timer to poll for DSC and
- * exit the driver.
- *
- * ide.c will then give higher priority to requests which originate from the
- * other device, until will change rq_status to RQ_ACTIVE.
- *
- * 4. When the packet command is finished, it will be checked for errors.
- *
- * 5. In case an error was found, we queue a request sense packet command in
- * front of the request queue and retry the operation up to
- * IDETAPE_MAX_PC_RETRIES times.
- *
- * 6. In case no error was found, or we decided to give up and not to retry
- * again, the callback function will be called and then we will handle the next
- * request.

- *  See linux/MAINTAINERS for address of current maintainer.
- *
- * This is the multiple IDE interface driver, as evolved from hd.c.
- * It supports up to MAX_HWIFS IDE interfaces, on one or more IRQs
- *   (usually 14 & 15).
- * There can be up to two drives per interface, as per the ATA-2 spec.
- *
- * ...
- *
- *  From hd.c:
- *  |
- *  | It traverses the request-list, using interrupts to jump between functions.
- *  | As nearly all functions can be called within interrupts, we may not sleep.
- *  | Special care is recommended.  Have Fun!
- *  |
- *  | modified by Drew Eckhardt to check nr of hd's from the CMOS.
- *  |
- *  | Thanks to Branko Lankester, lankeste@fwi.uva.nl, who found a bug
- *  | in the early extended-partition checks and added DM partitions.
- *  |
- *  | Early work on error handling by Mika Liljeberg (liljeber@cs.Helsinki.FI).
- *  |
- *  | IRQ-unmask, drive-id, multiple-mode, support for ">16 heads",
- *  | and general streamlining by Mark Lord (mlord@pobox.com).
- *
- *  October, 1994 -- Complete line-by-line overhaul for linux 1.1.x, by:
- *
- *	Mark Lord	(mlord@pobox.com)		(IDE Perf.Pkg)
- *	Delman Lee	(delman@ieee.org)		("Mr. atdisk2")
- *	Scott Snyder	(snyder@fnald0.fnal.gov)	(ATAPI IDE cd-rom)
- *
- *  This was a rewrite of just about everything from hd.c, though some original
- *  code is still sprinkled about.  Think of it as a major evolution, with
- *  inspiration from lots of linux users, esp.  hamish@zot.apana.org.au

- *
- *  Documentation:
- *	Datasheet is freely available, some other documents under NDA.
- *
- *  The ITE8212 isn't exactly a standard IDE controller. It has two
- *  modes. In pass through mode then it is an IDE controller. In its smart
- *  mode its actually quite a capable hardware raid controller disguised
- *  as an IDE controller. Smart mode only understands DMA read/write and
- *  identify, none of the fancier commands apply. The IT8211 is identical
- *  in other respects but lacks the raid mode.
- *
- *  Errata:
- *  o	Rev 0x10 also requires master/slave hold the same DMA timings and
- *	cannot do ATAPI MWDMA.
- *  o	The identify data for raid volumes lacks CHS info (technically ok)
- *	but also fails to set the LBA28 and other bits. We fix these in
- *	the IDE probe quirk code.
- *  o	If you write LBA48 sized I/O's (ie > 256 sector) in smart mode
- *	raid then the controller firmware dies
- *  o	Smart mode without RAID doesn't clear all the necessary identify
- *	bits to reduce the command set to the one used
- *
- *  This has a few impacts on the driver
- *  - In pass through mode we do all the work you would expect
- *  - In smart mode the clocking set up is done by the controller generally
- *    but we must watch the other limits and filter.
- *  - There are a few extra vendor commands that actually talk to the
- *    controller but only work PIO with no IRQ.
- *
- *  Vendor areas of the identify block in smart mode are used for the
- *  timing and policy set up. Each HDD in raid mode also has a serial
- *  block on the disk. The hardware extra commands are get/set chip status,
- *  rebuild, get rebuild status.
- *
- *  In Linux the driver supports pass through mode as if the device was
- *  just another IDE controller. If the smart mode is running then
- *  volumes are managed by the controller firmware and each IDE "disk"
- *  is a raid volume. Even more cute - the controller can do automated
- *  hotplug and rebuild.
- *
- *  The pass through controller itself is a little demented. It has a
- *  flaw that it has a single set of PIO/MWDMA timings per channel so
- *  non UDMA devices restrict each others performance. It also has a
- *  single clock source per channel so mixed UDMA100/133 performance
- *  isn't perfect and we have to pick a clock. Thankfully none of this
- *  matters in smart mode. ATAPI DMA is not currently supported.
- *
- *  It seems the smart mode is a win for RAID1/RAID10 but otherwise not.
- *
- *  TODO
- *	-	ATAPI UDMA is ok but not MWDMA it seems
- *	-	RAID configuration ioctls
- *	-	Move to libata once it grows up

- * PIIX4. Older device documentation is now a bit tricky to find.
- *
- * Errata of note:
- *
- * Unfixable
- *	PIIX4    errata #9	- Only on ultra obscure hw
- *	ICH3	 errata #13     - Not observed to affect real hw
- *				  by Intel
- *
- * Things we must deal with
- *	PIIX4	errata #10	- BM IDE hang with non UDMA
- *				  (must stop/start dma to recover)
- *	440MX   errata #15	- As PIIX4 errata #10
- *	PIIX4	errata #15	- Must not read control registers
- * 				  during a PIO transfer
- *	440MX   errata #13	- As PIIX4 errata #15
- *	ICH2	errata #21	- DMA mode 0 doesn't work right
- *	ICH0/1  errata #55	- As ICH2 errata #21
- *	ICH2	spec c #9	- Extra operations needed to handle
- *				  drive hotswap [NOT YET SUPPORTED]
- *	ICH2    spec c #20	- IDE PRD must not cross a 64K boundary
- *				  and must be dword aligned
- *	ICH2    spec c #24	- UDMA mode 4,5 t85/86 should be 6ns not 3.3
- *
- * Should have been BIOS fixed:
- *	450NX:	errata #19	- DMA hangs on old 450NX
- *	450NX:  errata #20	- DMA hangs on old 450NX
- *	450NX:  errata #25	- Corruption with DMA on old 450NX
- *	ICH3    errata #15      - IDE deadlock under high load
- *				  (BIOS must set dev 31 fn 0 bit 23)
- *	ICH3	errata #18	- Don't use native mode

- *
- *	If you are using WD drives with SATA bridges you must set the

- *
- *	If you have strange problems with nVidia chipset systems please
- *	see the SI support documentation and update your system BIOS
- *	if necessary
- *

- * The original SiS5513 comes from a SiS5511/55112/5513 chipset. The original
- * SiS5513 was also used in the SiS5596/5513 chipset. Thus if we see a SiS5511
- * or SiS5596, we can assume we see the first MWDMA-16 capable SiS5513 chip.
- *
- * Later SiS chipsets integrated the 5513 functionality into the NorthBridge,
- * starting with SiS5571 and up to SiS745. The PCI ID didn't change, though. We
- * can figure out that we have a more modern and more capable 5513 by looking
- * for the respective NorthBridge IDs.
- *
- * Even later (96x family) SiS chipsets use the MuTIOL link and place the 5513
- * into the SouthBrige. Here we cannot rely on looking up the NorthBridge PCI
- * ID, while the now ATA-133 capable 5513 still has the same PCI ID.
- * Fortunately the 5513 can be 'unmasked' by fiddling with some config space
- * bits, changing its device id to the true one - 5517 for 961 and 5518 for
- * 962/963.

- * DMA is not enabled automatically for this chipset,
- * but can be turned on manually (with "hdparm -d1") at run time.
