External backup drive has a new letter ....

Thread needs solution

Crazy computer. All these years the external hard drive has been Drive G:
Now it decides to be Drive F:. Of course Acronis doesn't recognise this change.
What do I do next?

I had exactly the same problem yesterday. I had only bought Acronis TI 2015 the day before, and had created my first full backup on the E: drive. As recommended, I was testing file recovery to another external HD. However, connecting that HD caused the drive letters to be reassigned, as the HD containing the backup became the F: drive, and the destination HD for the file recovery the new E: drive! Now, although I have since disconnected that external HD, the original one containing the backup file is still designated as the F: drive.

I got on to live chat, who basically said that the only option was to delete the backup task showing E: as the destination drive, and create a new one from scratch pointing to the F: drive instead. However that won't recognise the original backup file created by the previous backup task (when the F: was the E: drive), so the first backup file the new task creates will be a full one again rather than the incremental or differential it would otherwise have been.

The original backup file can be used for a disk restore if you reboot via the rescue disk, as you can then select the drive containing the backup file you want. You can still perform a file recovery operation without having to do a rescue disk reboot by double clicking on the backup file on your external drive in Windows Explorer, which will open it up so you can view the individual folders & files you wish to select and copy back.

I've got nearly 300GB of data backed up.
Don't tell me I've got to start from scratch again? Gollies!
Think how long that would take!
Then maybe the next time I turn on my computer the original Drive letter may reappear.

There's a computer guru at work.
I'll ask him on Monday as I think you should be able to force the Drive letter on the external Drive to another letter somehow.

There are utilities out there that let you reassign your drive letters - I wonder if that would help?

BRILLIANT! Thank you :)
Doing a Search,you don't even need a utility. Just go :-
Start, Control Panel, System & Maintenance, Admin Tools then Computer Management

I've now bashed that external Drive into submission.
What a relief!

If the assigned drive letter you assigned is low in the letter chain (D,E,F,etc.) you may run into trouble. As long as you keep your external drive attached to your PC you are OK. If you detach the drive for some reason then, attach a few other devices such as thumb drives printer etc. and you have used a low letter for your external drive say D or E with that drive unattached the letters D or E will be available in Windows and other devices attached can use those letters. If you then were to attach your external drive once again and it having an assigned letter of D or E that device would not be recognized because of other devices having used the assigned letter.

It is recommended that external drives indeed need letter assignment but that assignment should be high in the letter chain (X,Y,Z) to avoid this issue.
