The "Disk Management" picture says the the filesystem is "RAW" (instead of NTFS or FAT32).
This indicates that the
filesystem is damaged (there maybe bad sectors on the HDD).

It also shows that drive is "Active".
Only your boot drive should have an "Active" partition.

I don't think that Windows
"Disk Management" can remove "Active" from it.
I don't see any option when I check my
"Active" partition (I guess that reformatting it would do it).

If the HDD reappears in "Disk Management":

  • Right click on your external HDD partition.
  • Select "Properties"
  • Click on the "Tools" tab
  • Click on "Error checking".
It probably won't work though. :(

If it does work and the HDD starts functioning again, copy your files off it to somewhere else.
I wouldn't trust the external HDD with any important data, since it appears to have become twitchy.


Unless someone else has an idea, my suggestion would be use a Linux Live CD.

Can you get access to a Live Linux CD (e.g. Ubuntu)?
If so, see if you can view your HDD contents.
If you can, copy the files to a new location.

Once you have done that you can try using "Gparted" (a Linux Disk Manager):

  • To check the disk.
  • To remove the "Active" flag (from the external HDD. Don't remove it from your Windows partition).
  • To reformat the disk (worst case).

Note: these screenshots are from a Ubuntu 10.04 VM with one drive, so not all of the options are available.

Thaaaaaaaaaaaaaanks a lot,
i used your idea ( but with mac ), & it worked.
Question: sense my very lack of knowledge in Mac, i well use
Windows to format the HHD ( after i transfer my date ),
Do you think it's safe to keep using it after the format?
Or do i buy new one to make sure anything else doesn't happen again?

Can I ask which idea you used?

I wouldn't keep anything important on it.
I would only use it to transfer files (unimportant ones) between computers.

It may work properly (for a long time) but I would seriously consider buying a new drive to use for important files.


If you think that your problem is fixed, you should click the "Mark as Solved" button (see pictures below). :)
The first option requires you to leave a message.
The second option is the preferred method.

Maybe these pictures will help.
