Well, I think I managed to trash my Plextor 740UF.
I had the 740UF plugged in via USB (no other USB devices plugged in). When running BQFlasher with begb, I got a flash failed error message. Clicking ok it exited.
I was using the aspi4all adaptec aspi driver.
Rebooted, and now the system sees the drive as a "USB Mass Storage" device.
Changed the aspi to Nero and tried BQFlasher with /disableDriveChecking option.
It get's to the first warning message, click ok, message disappears, and then it just hangs in the background (no window appears).
Switched to firewire, but the drive won't show up.
Caddy won't open and light is solid.
Soooo... did I really trash this one?
Any ideas on why BQFlasher is hanging or how to get around this?
