Perhaps, but this is hooked up directly to the IDE controller port via an
adapter board (not PCMCIA). Looks like "vdd 1.00" and maybe "vdd 1.02"
versions don't work for me. I see posts that essentially say I can ignore
the error message, but I can't execute lilo on these disks which means I
can't boot from them.

Has anyone seem a correlation with the drive status error and the firmware
version? Based on the few units I have seen it looks like certain versions
fail more often. I check the version using hdparm. I get messages like
this:
kernel: hdb: drive_cmd: status=0x51 { DriveReady eekComplete Error }
kernel: hdb: drive_cmd: error=0x04 { DriveStatusError}
When I run things like fdisk, hdparm, mount, etc.

I have also seen drive status error on Apacer Compact Flash cards but never
on the SanDisk. The error occurs here when doing a MKFS (ext2 or DOS) or
trying to mount the device for the first time. When mkfs is rerun or
umount/remount is done the error does not reoccur. I have yet to see any
data corruption, although (IMHO) it doesnt fill me with a whole lot of
confidence.

I'm using SanDisk compact flash too, although I'm just using Red Hat's
mke2fs.
However, I have been experiencing problems with my filesystems which I
suspect are
down to the compact flash. Amongst these are UncorrectableError and
AddrMarkNotFound. These only appear on a very small number of cards after
they have
been used for a few weeks.
I always get a drive status error on the first access, but I assume this is
some
part of the IDE protocol which the flash cards do not support.
Has anyone else using compact flash cards also experienced problems?
Cheers,
Malcolm.
