SONY DRU500a Firmware update doesn't work

I bought a new SONY DRU500a VD/DVD writer with firmware version 1b. I’d like to upgrade this firmware to a new 3.20g but the firmware updater from Sony doesn’t work.
When I run the 500A320g.exe it writes in the “Detected drive(s)” window that “No updatable drives exists.” (I tried 500A_20f.exe also, with some result :-(( )

  • My drive in the WinXP is detected correctly.
  • DriveCheck from SONY detects my drive correctly.
  • I read instructions from SONY and everithing is OK…

Please help me, who know the reason?

Weird. Are you sure you followed the procedure correctly ? > DRU-500A/DRX-500UL FW update

Maybe your ASPI layer is not installed @all/corrupt :

I’v installed ADAPTEC ASPI driver pack v4.71.2 and now the update is working.

You should’ve done it before posting “your” suggestion here
