I downloaded a wrong Firmware, now in My Computer, my drive is not listed, when I was installing the firmware, it said do it at your own risk, now I am messed up
help bring back my old drive
About the only possible hope, is to find the correct firmware, and a dos flasher. Make sure the drive is the only device connected to the ide cable and try a dos flash (if you can find one for your particular drive model). It is a really big IF, but it's worth a try.
