I am RUNNING Win 2000 and have 2 ea HDDs one is a Maxtor 91024U2 and it says says "parameter is incorrect" when I try to access it. I can access its properties box and it says it is working properly.

I went into CMOS and had it auto-detect the DRIVE and restarted and still have the same issue. Can you help.

JWDownload/run the manufacturers diagnostic program for your drive. If you cannot find the Maxtor prog then use the Seagate Seatools one.

A comment extracted from another forum is "Judging by my experience and all of the forum discussions I FOUND, It seems like the problem is a weakness in Maxtor's compatibility with NTFS. LETTING Win 2000 run disk checking seemed to repair it in my case." You might want to run Chkdsk /f

Googling for your error in respect of Maxtor drives shows that the most likely problem is that the read/write head(s) contacted the surface of the platter causing damage - hope not.

Slaving the drive in another pc is reported to allow recovery of files. If the problem is caused by physical damage I don't see how this is feasible.

Good LUCK
