Peripherals forum: External Hard Drive wrongly shows almost full

Here is a screenshot of the disc and what it contains

I've seen several Backup programs that go nuts for all the space they can get. Some of them allow you to set a limit on that some don't. Some also hide some the files they create due to the belief that someone might delete them (either on purpose or by accident) and corrupt the backup. One more thing are there any hidden partitions? My HP has one. If you press F9 during the boot up it will load a "Diagnostic" Partition PC PITSTOP and run a set of tests on the computer. Could you have a hidden Partition? Hope this helps.

Just looking at your saved pic and straight away I see that Windows Easy Transfer is taking up 388 GB on that drive along with other folders I can see why you only have 4.76 GB left.

Delete Windows Easy Transfer folder then do another Transfer to get your backup. It looks like its done about four or five copy's of your data to the one folder as your master disk C is only 140 GB's.

Windows Easy Transfer maybe saving data to that file on that drive every time you start your PC. Once you have re-done your transfer that file should only be about 10 to 20 GB's depending on how much data you have in photos, videos and other personal files. Keep a check on the file size once new back up has been done and if it keeps increasing look for why.

At the moment that file on your F drive is three times the size of your whole C drive.
