Damn, I think I killed my drive.
I tried to flash my drive from 1.02 (not sure about the exact version but it was 1.x) because it didn't detect any of the UHDs I have. I used the patcher posted by TeddyRaspin, but didn't realize that I needed to change the firmware source.
After a while I realized my mistake and flashed back to the ASUS firmware this time using the modified flasher as intended.
My drive still opens and closes, but doesn't even spin up the disc or move the read head it also remain quiet during boot up.
What I tried to fix it:
I found an old Intel Core Duo system that runs it's SATA ports in IDE mode on which I installed FreeDos so I could run DosFlash.
I used the file again provided by TeddyRaspin thou this time the one that contains calibration data and the DosFlash.exe. This got stuck at writing to block_0 and then threw a bunch of FAT File system errors. I haven't figured out what to do with the DosFlash.typ File, maybe it has something to do with this.
I also tried the file I downloaded from the RedFox forum thread linked by SamuriHL this one ran through but didn't fix the problem. Again I don't know what to do with the DosFlash.typ file.
Can someone please help me fix this?
