Hp laptop running Windows 7 Home Premium, 64-bit. Machine is probably 2 years old.
Couple of days ago Windows Explorer lost the drive letters. My internal hard drive is now just "System volume" (which I chose trying to find the issue). No "C:" to be seen. Same with all other drives - internal partition ("Recovery" rather than "Recovery (D:)" or similar). When I mount a virtual drive using TrueCrypt it just shows as "Local disk....".
Looking in the Disk Management system the internal hard drives have letters (C: and D:). The virtual disk mounted does not. If I try to assign a letter to it the letter already assigned (but not visible) is not available.
In a CMD window all drive letters work fine.
I've restored to every point over a week back with no impact. (And no, I've not added anything personally or changed usage in weeks/months. Of course Microsoft makes changes weekly.)
