(In Windows xp )Convert FAT32 filesystem to NTFS

External Hard disk does not support bulk backup-transfer of data.
gives an error message no space availle in disk.
because disk has FAT32, so we wil fix this by converting disk to ntfs.
no data will be lost using this process, but it is always good to have a backup.

(In Windows xp )Convert FAT32 filesystem to NTFS using these Steps:
1. In cmd, Press in "CONVERT E: /FS:NTFS" (without the quotes).
   The E is for the letter your system drive, or external drive name. (see Step 5)
2. If it asks for the volume name then enter the name you see in my computer next to drive letter.
3. if the conversion fails the try this:
     chkdsk E: /f
this will fix errros on drive.
4. now again enter same command:
  CONVERT E: /FS:NTFS
It will convert the external drive FAT32 system to NTFS system.to verify conversion go back to my computer and right click at external disk and see properties.
