>Description:
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.

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