    connection. ALl works fine on xp computer, but when i plug into vista i

    Hi, ossy.

    What does Disk Management say about that HDD? What does it say in WinXP,
    and what does it say in Vista?

    Check in the DM Help file for instructions to add an HDD from another
    computer. Search the Help file for "foreign" disks.

    Other tools - such as Device Manager and Windows Explorer - are for showing
    us information about our HDDs, but Disk Management (diskmgmt.msc) has been
    the tool to actually manage HDDs (and optical drives, USB flash drives,
    cameras and card readers...anything that can be assigned a "drive" letter)
    ever since Windows 2000.

    I have never seen drives types identified as Internal or External hard
    drives. They are identified by their interface type (SCSI, IDE(PATA), or
    SATA and their interface max transfer rate. Any of these interface drive
    types can be mounted either internally or externally. All you did was take
    a drive that was mounted internally and connected directly to your MOBO and
    put it into an external enclosure that supported it interface type.

    Hi guys

    Firstly, they are sata drives in an external enclosure which support
    both esata and usb...

    In disk managment on Xp it says Basic 698.63GB Online Fat 32 Healthy
    (it was previously on NTFS giving me the same error in vista and
    reformatted to FAT 32 to get it to work with my PS3, which incidentall
    doesnt seem to support it either, but thats another issue

    In vista it only appears in disk managment for about 2 seconds. an
    then says "raw" instead of the fat32, then it disappears..

    However, i just tried to replug my second 750gb drive which has jus
    been reformatted to fat 32 and it seems to recognise it......thus i
    going to transfer my 650gb of data to see if it still works. both drive
    are identical by brand and by enclosure. even used the same partitio
    software. might just be a faulty drive, in which case its still unde
    warranty. Ill let you guys know tomorrow if that has sorted it out.
    Thanks for your input :

    Vista is a POS, and yes it was the enclosure :-

    Well I don't know which ones. I have an old 30GB 2.5" drive from a 6 year
    old laptop in an external enclosure and THAT works perfectly well with XP,
    Vista, Win 7 and Linux.
