External hard Drive issues

I have an external Maxtor 1 TB hard drive.  Recently my laptop (Dell - M90, Windows XP SP2) stopped seeing it correctly.  When I go to device manager, it is listed correctly.  In the Disk management, it only sees 321GB.  It shows the remaining 609 GB as unallocated.
 When I try to access it from windows explorer, it asks me if I want to format the drive.  If I connect the same hard drive to a different computer, it sees everything correctly.  I used this drive on this computer within the last month without problems.  Any idea what the issue may be?

Have you tried using a different usb port? Does it see a flash drive correctly?.
Ty this disconnect the drive go to control panel > system > hardware > device manager > view > show hidden devices
see if the drive is listed in hard drive and delete it.

CT,

  I tried every USB port on the laptop.  Same issue. I looked in the device manager and showed hidden devices. It is not a hidden device.  I even did a "right click" uninstall from device manager - rebooted - then reconnected. Same issue. I have other USB hard drives that work fine on this laptop and this hard drive works fine on other computers.   I ran a full virus and malware scan - on my computer and the hard drive (from my other laptop). No issues. This one has me stumped.

it can be your drive shows problems. probably with the file system, since it displays a bad size.
the best bet -  if it does not have warranty, is open the enclosure, and hook the drive directly to the ide/sata connector of a working system.
This will show if the enclosure, or disk is bad.
then try to recover your data first - if you can access it, fine, if not post back
then test your drive : http://www.seagate.com/www/en-us/support/downloads/seatools/

nobus,

 The drive shows completely fine on my other systems (laptops and servers).  The issue only exist on the laptop that I use for business travel - the one I use the most.  I have run a chkdsk /f, and full virus scan from a working system on the external - no issues reported.  I also did both on my travel laptop - no issues reported.

I did the remove USB thing and no changes. The issue is now happening on my other laptops.  Must be in the external.  Now I need to recover my data from it.

I am trying the seatools now.

the best is the DOS test, but i think that does not  work with usb drives - so try the other one

No.  I had everything disconnected from USB ports when I did that.  I think this one is a lost external HD.  Just seemed odd that I could use it on several systems, but not one for a while.  Thanks for the help.  I am going to close this out.

External Hard Drive is corrupt or physically damaged.  No success in recovering data.
