Sounds like you need a quirk/blacklist entry for that drive, if it
doesn't support 0x00 as meaning 256 sectors. If you are using libata,
you can add a ATA_HORKAGE_MAX_SEC_128 entry to ata_device_blacklist[] in
drivers/ata/libata-core.c

I'm using IDE driver instead of HD driver.

Then you need to add check for this device to ide_disk_setup()
(prior to blk_queue_max_sectors() call) in drivers/ide/ide-disk.c.

Thanks,
Bart
