I've got Windows 7 RC installed on a Dell Inspiron 6400 (dual boot with openSuse 11.1). I have a 250 GB USB external SATA HDD in a NexStar3 enclosure recognized in Ã¢â‚¬ËœDevice Manager Ã¢â‚¬â€œ Disk DrivesÃ¢â‚¬â„¢ as Ã¢â‚¬ËœMaxtor 6 V250F0 USB DeviceÃ¢â‚¬â„¢. 'Properties' tell me the device is working properly, although I canÃ¢â‚¬â„¢t populate anything in the Ã¢â‚¬ËœVolumesÃ¢â‚¬â„¢ tab (I get a Ã¢â‚¬ËœVolume information for this disk cannot be foundÃ¢â‚¬â„¢ error.) The drive doesn't show up in Ã¢â‚¬ËœComputerÃ¢â‚¬â„¢. If I go to Ã¢â‚¬ËœComputer Ã¢â‚¬â€œ Manage Ã¢â‚¬â€œ Disk ManagementÃ¢â‚¬â„¢, the drive doesnÃ¢â‚¬â„¢t even show up in the list of volumes. So itÃ¢â‚¬â„¢s impossible for me to just reactivate it or format it. The drive was recognized just fine in my previous Windows XP partition on the same laptop. The drive is currently recognized just fine in my openSuse 11.1 linux partition. There is nothing in the BIOS that would allow me to tweak the SATA drive options. I tried putting *another* SATA drive in the *same* NexStar3 enclosure. Same problem. I tried connecting the *same* SATA drive in *another* external enclosure. Same problem. I tried connecting *another* SATA drive in *another* external enclosure. Same problem. I have an IDE 400 GB external USB HDD in another NexStar3 enclosure that is recognized just fine in Windows 7. I assume itÃ¢â‚¬â„¢s a Windows 7/external USB SATA issue. WhatÃ¢â‚¬â„¢s wrong? Can anyone suggest anything? Thanks a lot.
