I was not sure which section to post this question in, sorry if I chose the wrong area. I recently was doing some digital forensics homework that involved acquiring data from an image file of a FAT16 drive. I was going through the assignment and when selecting the target drive to copy to, I accidentally clicked my external back up drive instead of the USB that it was meant for. I cancelled the transfer but the file system had already changed from NTFS to FAT16 and cleared out the drive. I have tried to convert back with convert *drive*/fs:ntfs in cmd, which now says there is not enough disk space to complete the conversion. (even though the drive is a 1TB drive.) The drive shows that its current capacity is 100MB. Chkdsk comes back with no errors in the drive. Does anyone have any idea of how I could fix this problem? I was hoping that maybe it was a new partition to the drive but it does not seem to be the case. The software used when this accident happened was ProDiscover Basic.
