    G'day there and welcome to the forums.

    All external peripherals disconnected prior to running AHT? Another good indication of problems ion S.M.A.R.T. Status under Disk Utility. Just click on the top listed drive and see what it says.

    Have a look at this link:-

    yes all peripherals were disconnected prior to running the AHT. i broke up the RAID then ran the test on each drive one at a time and only got this error message on one drive out of the 4 drives.

    i took a look at that link above and it was no help to me.

    Ok boot from your install DVD, go to Utilities, select Disk Utility and Drive 4, or whichever one came up faulty, and run Repair Disk.
