Summary: writing to ZIP 250MB drive bombs via ATAPI interface

Description craig 1999-10-05 02:30:00 UTC 
Writes to a ZIP 250 disk in my ATAPI IDE ZIP 250 drive fail.

I can format the disk with /stand/sysinstall.  I can create directories.
But if I attempt to write data, CP freezes.   After CP freezes, various
things have occurred.  In some cases the kernel starts spitting out
an error continuously:
wfd0: i/o error, status=51<ready,opdone,check>, error=40

Most recently, the result was a long pause, no error message, but then
my hard drive (not the IOMEGA) began spinning continuously and any
attempt to touch any disk locked up.

Fix: 

None, though I wondered if the larger disk geometry caused a field
size to be exceeded.
How-To-Repeat: mount a 250MB Zip disk and try to write a large file (like the
kernel to it).

Over to Mr ATAPI. He'll probably want to see a copy of your kernel config 
and the output of dmesg(1).
