Not an IT pro? I had a backup for it but, sometimes even that is a pain to have to deal with. All is good. I do want to share one thing. One of my FAT 32 flash-drives showed 03 in offset 41 5 down 2 across instead of 01 as is mentioned in the instructions.

So, I changed the 03 to 00 and gave it a go. Worked like a charm. When I ran a search from that location for the bit string, it came up with a result at address 31DE0. Changing the appropriate bit at that address did nothing.

At least as far as dirty status! I then went back and manually entered 0 in the cluster selection window to start at the beginning of the disk.

Then when I searched it found a result at address 3DE0, which was the correct one. Changing the appropriate bit there changed the disk status to NOT dirty. Huh… may someone help me?

Damn it! Some tips would solve this i hope. Thanks, Untitled from Moon. If not, are you running a dual boot system? I changed the dirty bit 03 01 01 01 00 00 00 00 80 00 00 00 18 into 03 01 01 01 00 00 00 00 80 00 00 00 Thank you, Raymond, for explaining how to clear the dirty bit on my USB flash drive.

This left me stuck in a loop until I manually cleared the dirty bit. Is the FAT32 filesystem corrupt? Maybe, maybe not. Put it back in my laptop, and now it boots up fine — thank you thank you!!
