I just experienced a blown power supply, and in recovering my system, I had to move a disk drive from an internal SATA controller to an external USB enclosure because it has a broken SATA power connector.
When I plug in this drive via USB now, it powers on normally and Windows immediately detects the drive, listening it in Device Manager as operating normally.
However, the NTFS volume on it does not appear in explorer, and I see no indication of the dis k or its volumes listed under Disk Management.
I plugged the same disk with the same USB enclosure into a Linux machine and it sees the NTFS volume okay.
Why would Windows completely ignore this volume? Would it do this because it thinks it is damaged? Is there any log that might give more insight?
