1st drive link.
000J is listed as one firmware version, so I think that might be the right one.
Other option - open the PC and look at the labels on the drives. Even drives that don't have labels on the front usually have something informative on the top of the casing.
As for that other drive, the thing with Aopen in the info string, don't know. Look for other labels or markings on the entire drive.
Just be sure that it's the right firmware for the drive. Otherwise, you might have a brain dead drive that's not able to figure out how to load another firmware. Translation - you'd need to get a new drive.
