So here's the deal. After looking around my external hard drive earlier, I got into a folder and noticed at least 2/3 of the sub-folders were missing. I checked around the other areas of the drive and nothing else had been affected.
For some reason the files have vanished into thin air!
When I click into the main folder (with the sub-folders missing) it runs slower than normal. After all this, I had been looking around the remaining sub folders and deleting some files whereupon I tried to press the back button to the main folder directory and what was left of the sub-folders had ALL dissapeared now.
I don't know where they have gone and am afraid of this happening to other files on my external HD like my catalogue of digital photos from 2003-present day!!!
I haven't done anything irregular, this seems to have happened without warning.
The space left on my external HD has not changed although the folder says it is empty and is '0 bytes' when it was originally approx 5 gigs so perhaps it has to be somewhere?!
I tried searching for sub folder names but no luck.
Thankyou for ANY help!!!!!
