Pool IDE drive has dropped into PIO mode - can I remove and salvage backups? RRS feed

  • Question

  • I am replacing my two 500GB IDE pool drives with a 1TB SATA drive. I successfully removed the first 500GB IDE last night. I started the remove process on the second drive early this morning. It was going extremely slow so I went into device manager and determined that ATA133 drive had dropped into PIO mode which explains why it is going so slow. At the current rate of transfer it looks like it will take days to transfer the files over to the new 1TB SATA pool drive. In Device Manager I can only choose "UDMA if possible" or "PIO Mode". I have it set to "UDMA if possible". It looks like my only choices are:

    1. Wait days until the Remove process finishes, or
    2. Shut the WHS server down, remove the IDE drive, and start new backups from scratch.

    If practical I would like to salvage my backups, but I can live with starting from scratch. Any recommendations?

    First, it's possible that no portion of your backup database is even on that drive.  In any event, you could try the BDBB add-in to backup your backup database (although, if the drive is that unstable, it might run just as slow doing any type of copy function).  If that's the case, it would probably be better to just let it go and start over.

  • My recommendation would be to try setting the drive back to UDMA mode, if possible. See this knowledgebase article for more details. If it steps back to PIO mode again, the disk is failing and should be replaced, which you already plan to do. :)

    I'm not on the WHS team, I just post a lot. :)
