When I go to delete/create/modify a file from a flash drive that is formatted with ExFat when Windows says the drive needs to be checked for errors, I cannot delete any files.
Why can't I delete/create/modify without using chkdsk first on ExFat, yet I can on NTFS and FAT32? How can I get around this as some computers I use don't allow us to access chkdsk or even the Safely Eject taskbar icon?
Answer
Open an elevated Command Prompt and run:
fsutil dirty query X:
Where X: is the drive letter of the flash drive.
If it is 'dirty', then you have only 2 options - either you run the chkdsk or you save your files and reformat the flash drive.
Another (theoretical) option is to clear the dirty bit with a hex editor. But that is pretty tricky and I have not yet seen a solution for exFat - only for NTFS, Fat32 and Fat16.
