External hard drive not accessible

[triptronick]

Hello,

My toshiba external hard drive shows in the device manager but is not accessible through my computer. Any suggestions?

How do UVCView and HD Sentinel identify the drive? UVCView talks to the USB-SATA bridge IC inside the enclosure whereas HD Sentinel attempts to communicate with the HDD behind the bridge.

Does the drive appear in Disk Management?

Does it have any data?
