My Passport Essential USB3. Encrypted with Unlocker. Used for 2 months with no issues (I plug-in, drive K: appears, I run unlock, enter password, the “data” drive L: appears with the disk contents).
Now the “data” drive does NOT show in “Computer” or anywhere else. Device Manager all OK.
Disk Management DOES show the unit but, unlike the other drives in the PC, it is marked “Offline” and has no drive letter (context menu grayed out).
Rebooting/pluggin to another USB3 port does not resolve the issue.
Please help: I have hundreds of valuable info in this drive!
