PROBLEM: Can't mount 2048 hardware sectors SCSI disk

PROBLEM: Can't mount 2048 hardware sectors SCSI disk

[Yokota Hiroshi]

[1.] One line summary of the problem: Can't mount 2048 hardware sectors SCSI disk on 2.4 kernel.

[2.] Full description of the problem/report:
 I have SCSI optical disk drive. It's supports 512 and 2048 bytes hardware
sectors media.


 In 2.2.19 kernel, I can use both 512/2048 hardware sectors media.

 In 2.4.3 kernel, I can mount 512 bytes hardware sector media correctly, 
but I can't mount MSDOS/VFAT/UMSDOS/HFS filesystem in 2048 bytes hardware
sectors media (reports "wrong fs type"). But I can use dd/mtools/hfstools
correctory .


 I tested "Workbit NinjaSCSI-3" and "Adaptec APA-1480" SCSI host adapter.
Both of them reports same error.


 I turns on "CONFIG_SCSI_LOGGING" option to debug.

 Log reports SCSI disk driver (linux/drivers/scsi/sd.c) wants to read
non-existant sector. (set very big sector number to SCSI packet)

 I think something wrong in SCSI driver or filesystem driver in 2.4 kernel.

[3.] Keywords (i.e., modules, networking, kernel): SCSI disk

[4.] Kernel version (from /proc/version): 2.4.3

Hi,

I reported the same problem a while ago. The suggestion was to stick to 2.2.19 for
the time being. 2048 byte/sector support is broken in 2.4.
