Command Compliance Testing for ATA & SATA disk drives
This paper will describe a command compliance test to be used on ATA and SATA disk drives. A command compliance test should issue any task register command to any serial ATA or ATA disk drive and record the results of the command. This method of ATA/SATA testing allows the user to confirm whether a given ATA or SATA disk drive complies with the published ATA specifications, as well as to test non-standard or vendor unique commands. For reference, ATA and Serial ATA documentation can be found at www.T13.org.

Ask Dr. SCSI – “Are there any SCSItoolbox Suite tests that can tell if my drive is about to stop working?”
Q. “Are there any SCSItoolbox Suite tests that can tell if my drive is about to stop working?”
A. “The Sequential Defect Map Test will read every block on your drive, and will show you any extra effort that the drive had to make in order to deliver your data correctly. Did it need to use ECC? Did it have to use retries? Were negative or positive offsets required? Up to twelve types of correction methods are shown by this test, with a counter for each method.
If your drive isn’t having an easy time reading data today, it may not be able to at all tomorrow!”
Did you know? – Repair DLT directory
That DLT tapes keep a directory of the tape contents at the beginning of the tape. This helps the drive perform seek and positioning commands more efficiently. This directory is updated any time the tape is unloaded from the drive. But what happens if you are writing data to the tape, and lose power before unloading the tape? The tape directory gets corrupted is what happens! But not to worry, just use the Repair DLT directory function to fix it!
This function will tell you if the directory is corrupted, and if it is it will fix it. Depending on how much data is on the tape, this function can take a long time! But if your tape directory is corrupted, it’s worth the wait!>
