Can I use convert.exe to convert my ExFat drive (Which is 3TB and not the boot drive, if that matters) to NTFS?
I'm in Windows 8, and I SERIOUSLY need to convert my drive, preferably without data loss.
From what I have found online running convert.exe on a exFAT drive will give you the error "CONVERT is not available for EXFAT drives."
It appears you will need to copy the data off, format the drive, then copy it back on. There is no in-place way to change the filesystem inplace.
(If you don't have a spare drive to copy to, you can play "leapfrog" and use a partition re-sizing program and make a new NTFS partion out of the free space. Once you have done that go back in to windows and copy all you can. After that go back in to the partition program and shrink the exFAT partition and grow the NTFS one. Keep repeating till you have copied all of your files.)
