ide-scsi emulation for zip drive, should I be worried

[Gregory Nowak]

Hi all.

I just enabled ide-scsi emulation for my 250 mb ide-atapi zip drive. Everything works, but I get the following in my dmesg output.


hdd:<3>ide-scsi: hdd: unsupported command in request queue (0)
end_request: I/O error, dev 16:40 (hdd), sector 0

 unable to read partition table


Later on I get:

Is this normal, or am I missing something?

Thanks.
