Error Message:
Error during disk write
Explanation:
During a file system conversion from FAT to NTFS, the Convert utility was unable to write a structure that is part of the NTFS file system description.
User Action:
The FAT partition is still in its original (unconverted) state. Run the Chkdsk command with the /r option on the FAT partition to map out bad (unwriteable) sectors. Then try the conversion again.
