Description jjd202 1999-06-22 20:59:57 UTC
I'm putting this under mount b/c I'm not to sure where else
it would fit... I'm pretty sure it's not a physical problem,
it works fine with 5.2 and *cough* Windows, but for some
reason RH6 wants to give me a hard time...

When I first set up the mount point under linuxconf i got
the error:

"hdd: The drive reports both 100663296 and zero bytes as its

While reading from and writing to the drive, I get the

"ide-floppy: hdd: I/O error, pc=0, key=2, asc=3a, ascq=0",

			- and -

"ide-floppy: hdd: I/O error, pc=2a, key=2, asc=3a, ascq=0"
"end_request: I/O error, dev <time> (hdd), sector < # >"

Both errors repeat until the process is complete.  When
reading, I end up getting the data uncorrupted... but it
will not write properly.  I've tried everything I can think
of to fix this... not a severe problem, but it makes my
weekly backups a pain in the *@^#%... %)

We have observed this to be a problem and are working on a soltution.
Basically it is a kernel bug and the patch will be hopefully
incorporated into our next kernel release either in errata or

Until then you can use ide-scsi emultation which allows the zip drive
to work properly.

add to your /etc/conf.modules file the following line

alias scsi_adaptor ide-scsi

if you've got a device that needs to be ide-scsi and don't have any
scsi devices, and

post-install scsi_hostadapter modprobe ide-scsi

if you've got other scsi's and scsi is in kernel, use

install ide-scsi modprobe ide-scsi

Upon rebooting of the machine you can do a modprobe ide-scsi which
will find the zip drive and tell you what scsi device it is assigned.
Normally it will be /dev/sda4 or something similar. Then you would
just do

mount -t vfat /dev/sda4 /mnt/zip
