I found "testdisk" and ran the dead drive through it many times always ending up with "no partition". The next option I see is to "Add partition" (type "A"), which is where I am now....but this is way above my paygrade and I have really NO clue what to enter in the various cylinder, head, etc..
Can somebody HELP pls...in French or English , either is fine.
Thanks a lot!!
The drive is out, connected to another computer through a USB adapter. I can hear it work fine...
I tried to cc/paste (prt screen) but it doesn't work (I'm really above my depth apparently
