Recently, I used Rohos Mini Drive on an old 1GB Freecom USB drive I have. Rohos uses up half of the space, so left me with just under 500MB for storing my documents. When I later reformatted the drive, it was now only giving me 500MB total (after removing Rohos and completely reformatting it)
Windows would recognize the other 500MB but not allow it to be formatted, and I couldn’t find any solutions on the internet about how to get it back, or any other tools on the internet that would be able to get it back either.
Then today, I found HDDGURU’s HDD LLF (Low Level Format Tool) and after 2-3 clicks, it had fully formatted the USB drive in a few seconds (using quick format) and given me all of the space back
It’s completely free for personal use as well, the link is below
