I have a very odd problem with a one of my Maxtor D740X hard disks. If you copy small files to it (loads â€“ like the contence a windows dir several times (to fiill most of the 60GB), and then try to copy them somewhere else some of the files come up with an error along the lines of â€œfile is inaccessible â€“ unable to read from source diskâ€ and large files copied to it eg. divX films get a lot of corruption to the picture.
I suspected the surface of the disk must have been damaged somehow, so I formatted (full) the drive (NTFS) ran Scan disk from xp, (which picked up picked up index references to the files which were reported as inaccessible, said the file didnâ€™t exist and deleted the index entry for it) installed and ran Norton disk doctor, ran the Maxtor diagnostic software and re-factory certified the drive, and went through all of the other Maxtor drive tests, and they all came up saying the drive is fine. I get back to windows, and find after formatting it again the problems are still there
The drive is connected to a High point 370 raid controller running in UDMA 100 mode, along with another identical drive on the other channel of the controller (not in raid) which is fine.
I want to return the drive under warranty, but when the manufactures diagnostic software reports the drive as fine like everything else â€“ which is very apparently wrong, this is slightly trickyâ€¦
