SubjectRe: jaz-drive is sleeping
High!

I have also a problem with a "sleeping device":
A EZFlyer (230MB) attachedd to my external
SCSII-Bus (NCR53x810). After removing a media
from the drive and wating for <n> minutes, I
cannot access the drive any longer. Sometimes
it would help to re-insert the media several
times until sthe drives wakes up (you can hear
click--clack--clack from the read/write heads
then. Often I have to reboot. The first time
before I recognized what's going on I hang
the kernel by mounting the sleeping Flyer.
No timeouts! But I think, there should one
be implemented?!!

Is there a chance to reset the SCSI-Bus for
scanning all devices a second time?

I am still using 2.1.13...

KEEP HACKING!
