Sata drive won't work in external enclosure

    I have a Maxtor Diamond Max Plus 9 120GB SATA 150 hard drive that works fine
    in the computer but when I place it in an external enclosure it can't be
    read or mounted by either my Win XP PC or my Macbook Pro.
    I have tried various external enclosures, with USB and with firewire
    connectors but the drive will not show up in either computer when connected.
    The same enclosures work fine with other SATA 150 drives but not with the
    120GB drive.
    Can anyone suggest what may be wrong? Do I need to set any jumpers on the
    drive?
    Why would a drive work fine when installed in the computer but not show up
    when placed in an external enclosure?
    Thanks a lot for any advice.

    You may need a SATA II PCI-Express card (or a SATA II motherboard
    slot) . You can check here for more info: http://www.satadrives.com/

    I, too, have that problem with a couple of SATA drives, and I do have a SATA
    II PCI card. Still won't mount. I futzed with it for a few hours, then had
    to move on. I haven't got back to it. I'd love a solution to use these two
    drives externally.

    I may have an answer.
    I couldn't get the drive to appear in Windows or Mac, but in device manager
    the drive shows up in the list of disk drives.
    In drive management, it also shows up as a disk but with a warning symbol
    and says dynamic while the other disks are identified as basic.
    If I right click on the disk in drive management it will allow me to convert
    to basic but that will wipe out the files on the drive so I haven't done it
    yet, but it appears that neither the drive nor the external enclosure are
    faulty. The problem is that the disk may need to be converted to basic in
    order for it to show up normally when connected to the computer.

    Correct.
    XP won't allow externals to be dynamic.

    Sorry I didn't read this sooner, I learned that myself when I was
    experimenting raid striping external drives.
    That won't work either since the disks have to be dynamic to stripe.

    The dskprobe utility is supposed to allow changing from dynamic to basic
    with *potentially* no data loss. The alternitive if there are important
    files is I guess to mount it internally, make a copy, convert to basic and
    copy back.

    That's probably the clue. I had that too with an external Sata disk .
    Strangely enough Sata needs a reboot to recognise a drive. Pretty
    silly if you have an external drive, of course :(

    Check and make sure the druive is not setup as a drive that can be quick
    removed. You may have to reformat the drive as NTFS. I just added a 1TB
    external to my setup and it had to be reformatted. XP warned me that the
    drive was setup as a quick removal drive and would need to be reformatted ..
    which means you must use the tool to safely remove drives from the system..


    NOt sure what it all meant as I just did it and moved on.

    Hi Nappy,

    Usualy you can change this also by accessing the properties of the drive,
    click hardware, click the drive name, choose properties, choose policies,
    then set whether it will be 'Quick Removal' or 'Optimize for perfomance'.

    You should be able to do that and not have to reformat.

    I have a couple externals that always stay plugged into a computer, so I
    change them to 'Optimize for Performance'

    ha! I had no idea. I haven't used much external storage since firewire. I
    think I have some 20 TB around here.. !

    Yes. I was warned when I went to format the drive about the quick removal
    stuff..

    Come to think of it.. it did mount though..
