Dead drive? PLEASE HELP! - Nec 5100

I just recently flashed my nec 5100a drive with the 5500 hacked firmware using NecFlash. When the flash was complete the drive’s led stayed on. I also could not eject the cd tray. I restarted my computer and the led stayed on and I still could not eject the cd tray. Also, my laptop did not recognize the drive anymore. I flashed the drive in command prompt and have a Dell Inspiron 8100. Please help me!! Is my drive dead or is there any way to recover it? What do I do? I do have a backup of the original firmware but I don’t know how to flash it because my computer doesn’t detect the drive. :eek:

Was the drive on IDE or it was in some other Dell-specific way ?
