I have a LaCie Biggest F800. This is a USB2.0-connected RAID drive. I have three computers. Computer #1 runs WinXP Pro SP2. THis is where the drive was connected. It works fine there, formatted with NTFS, no security. If I plug it in to computer #2, which runs WinXP Pro SP1 it is recognized and works fine (automatically assigned a drive letter and is readable). This helps to confirm it's not a security issue. If I plug it in to computer #3, which runs WinVista Beta RC2 it is physically recognized-- i.e. the device manager recognizes the device (including the name "LaCie Biggest F800"). However, that's where the OS stops working correctly. ~50% of the time the disk management console does not display the disk at all. While sometimes, diskmgmt does display the disk, but marks the type and status as "unknown". - There is no right-click option to assign a drive letter - I have tried rebooting (with the drive connected and not connected) - I have tried various USB ports - I have connected the drive powered up and powered down - I have tried disabling UAC - I have tried contacting LaCie... they do not officially support vista at this time. After stumping my IT colleagues... any help would be GREATLY appreciated!! Best, Lon
