So tested the drives of the 210 and the 270c on a PB170. Both are Ok, only the one from the 210 is very very noisy...

The password protected one (from 270c) wouldn't mount, even when booting on a floppy. Hooked the 170 to a 1400c in SCSI,

and tried to mount the HD with diskSetup, but it would see the HD only to tell it could be initialized… so i did.

I have yet to install a Syst 7 , then put it back into the 270c. But enough for this evening
