I have done backups every few days recently and decided to see if I could Restore some files. But the Restore function can't find any Backups (View All gives No backup set selected).
There is a problem with the external HD where the Backups have been done: the disk no longer is able to delete/move/rename/copy. files. Files can be opened with their usual apps (picture and video viewers, Acrobat files, etc.) and folders look OK.
I'm using Win7 but I can't find any disk diagnostic programs-except Defrag, which is unusable because the disk is too full (less than 10% free space remaining). I've tried several things including removing the disk and re-connecting it after re-boting; using a program called Unlocker (it couldn't find any Locked handles but tried to delete a folder and then a single file anyway, claiming success but not achieving it); un-setting the Read-only attribute and then finding it hadn't actually been changed after clicking on the Apply button.
So, how could Backups of some files have been done up to May 8 and none of them can be found by Restore file?
