ST340823A disk size issue

[Mikko Rapeli <mikko.rapeli@iki.fi>]

Hello, 

(More details at http://bugzilla.kernel.org/show_bug.cgi?id=8816 )

My home server disk doesn't work with latest kernels since its size is
reported or probed correctly. With 2.6.22.1 I get:

Probing IDE interface ide1...
hdd: ST340823A, ATA DISK drive
hdd: selected mode 0x42

hdd: dma_intr: error=0x10 { SectorIdNotFound }, LBAsect=78165360,

...

And as said shows in bugzilla, badblocks, fsck and smartctl think the
drive is not broken or going to die too soon.

What's the difference between the size formats of
WIN_READ_NATIVE_MAX_EXT read by
ide-disk.c/idedisk_read_native_max_address_ext() and (hdreg.h) 
hd_driveid->lba_capacity_2 read by, if I read drivers/ide/* code
correctly, ide-probe.c/do_identify()?

If this disk is reporting one of these wrong, which fix could be
applied? 

Both disabling 'stroke' and removing addr++ in
ide-disk.c/idedisk_read_native_max_address*() fix the problem, but if
kernel code is correct and standard compliant, these fixes are out of
the question.

Perhaps a boot parameter to kernel could force the disk sector count to
some value for buggy drives?
