I cant find it in it either.
Please help.. what should I do? Is it recoverable?
Change drive letter is not available... as shown in the screenshot the disc cannot be initialized...
I had mounted a encrypted partion from it.. which i have been using for a long time.. the computer hung.. and i had to hard restart it.. since then.. its dead... That is *.flk file you mount using folderlock.
when I mounted and it showed a new drive as usual and it hung!

I did run wd diagnostic tool...
quick test was a PASS
Extended test failed to repair bad sectors.

In R-studio the drive is shown.. but when selected.. the scan button is invalid.. I cant run scan on it.

When I listen to the drive.. it spins for like 1 min.. then pause for some time.. and spins again..
