Thanks, on the downside i have spent all day testing some items.
I turned my attention to the Macway syquest drive first, was connected to my PM 7600...which was reluctant to boot in the first place
I just discovered that the HD finally gave up, the floppy drive also was reluctant to work and was unable to read my copy of Scsi Probe
When everything was solved on the 7600 side, the Syquest was unable to mount and Scsi Probe kept complaining about the bus not being terminated.
Using a terminator and not only the terminator switch didn't improve things, Scsi Prove can actually "found something" but wasn't able to mount. (so i think this drive is gone bad)
I tried the Nomai
for a change, and this time everything went fine
(the small drive is a pleasure to use, is nice and can read 270 and 540 Mo disks)
All except one disk are OK, i have got a tremendous amount of games, applications and a Mac Os (7.6) on those disks.
The Caddy drive was also tested, and worked...only once
wasn't able to make it work twice !!
And the Powermac is working great of course
So half is OK and Half is not, not bad after all.
