External hard drive not being recognized

[dreamerboy]

i tried converting my external har drive from fat32 to NTFS using : Type Convert Drive letter : /FS:NTFS so I entered "convert G: /FS:NTFS"

at the end it said data error cyclic redundancy check
after this my computer stopped responding and i had to do a hard restart.
after this the hard drive was not being recognised at all,not in device manager also.

the hard drive does have power and the light goes on,it also makes the sound when it is being read.

please assist

Only suggestion I can think of is to go into Device Manager and uninstall the Mass Storage Device under Universal Serial Bus controllers. If it does not show up you may have to show Hidden Devices and see if you can then.

Let it reinstall the drivers for it and hopefully it'll be recognized.
