Though it is a 6E030L0510213 MAXTOR DiamondMax Plus 8 30 GB Hard Drive, it is detected as a 40G N40P (Factory name). I have tried inputting the correct values for Cyl/Hds/Sec but the drive fails and is unreadable. As far as I can tell the actual data is fine and the drive is fine, it's just this error that changes the firmware settings back to the N40P values.
We appreciate the support you provided in this matter. Thanks a lot for fast, professional service.
