[sdiy] OT: how to save a dead Raided Drive?

[Dan Snazelle]

ok

SORT OF GOOD NEWS

i got another lacie power supply

guess what? after switching the old for the new, the drives are spinning again,  as they should. i can hear it whirring up and it seems to be OK
BUT, my computer is not recognizing it.

so i am wondering if the defective PSU could have fried the Raid circuity?

or the usb part of the circuit?


first sort of good news all day

thanks all
