Windows 7: External HDD corrupting? Cannot view in Explorer or Disk Management

External HDD corrupting? Cannot view in Explorer or Disk Management

I have a WD MyBook 3 TB external HDD. I can see the drive letter in Windows Explorer but the name I had for it is no longer there and the window freezes when trying to access it, disallowing viewing of any files. I was going to take a look at in through Disk Management, but when opening DiskMgmt with the hard drive plugged in the window never opens and reads 'Connecting to Virtual Disk Service'. When the hard drive is unplugged I can use Disk Management just fine.

The drive is able to be viewed in Device Manager. I tried uninstalling the drivers but this did not work.

I am currently running a "chkdsk /r" on the drive. It has been running for about 9 hours now and is 0% complete on verifying files and folders. (see image) Before it started this step I noticed it was back to normal in Windows Explorer, but I did not try to open the drive to view any folders. It also showed up in Disk Management as that was open in the background when I started the command.
I found this very odd, because once this step started it was back to the issues before.
Do you think the chkdsk is working properly? I can hear the disks spinning and the light is flashing like it is being used. I would like to preserve the 2 TB of data in use, but if it's not an option I would just like to be able to use the hard drive again.
Would quitting out of this cause damage?

The issue started after using my netgear r6300v2 ReadyShare feature. I used this in the past with success, but stopped since it took forever to reindex and view folders/files when I accessed it through DLNA on my ps3. I was going through the files that were showing up and it suddenly stopped working. The drive was not even viewable through the routers settings after this happened, and all the issues listed above started showing.

I have tried it on another PC and received the same issues as well.

Any thoughts or advice? Should I just leave the chkdsk running? Should I kill it and try to duplicate the results where it appeared to be back to normal - just run a chkdsk instead of a chkdsk /r?
Any thoughts or advice would be greatly appreciated.

A problem I see in the picture is that it mentions "the type of file system is FAT32". The size of the drive is too large for FAT32 so would have to be formatted as NTFS but doing so will delete any files on it.

FAT32 can handle up to 16TB. The 32GB limit is set to promote the NTFS and because it is more efficient to use in larger partitions. I reformatted it to FAT32 a couple years ago and never had issues till now. Could it be hung in the chkdsk because it is not NTFS?

Hi there.

I agree with the others - reformat the drive in NTFS and see if this will solve the issue. If it continues to act the same way, run a test on the My Book with Data Lifeguard Diagnostics to see if anything wrong will be detected. You can download it from here:

Well I cancelled out of the "chkdsk /r" command because it still wasn't moving after 36+ hours. I decided to run only "chkdsk" after that. For some reason the drive then showed up like it was back to normal and I am able to view the files finally. I will be taking your guy's advice and reformatting to NTFS after I try to back up some of the 2TB of data on the hdd.

Here are the results of running "chkdsk E:" Any thoughts about what it says here?
