I have a 1TB Western Digital My Passport USB3.0. It is a USB powered external HDD that came NTFS formatted out-of-the-box.
Recently, I noticed that some of the files I had stored on the HDD became inaccessible. They still showed up when browsing the drive, but had a lock icon on them. Looking at the security properties on those files, I noticed that none of the users (Everyone, SYSTEM, and an unresolved SID) had any permissions on them.
I ran Windows' check disk utility on the HDD with both check-boxes selected ("Automatically fix file system errors" and "Scan for and attempt recovery of bad sectors"). The utility ran for over a day and still did not finish, so I tried to cancel it (it had gotten to ~95932923 free clusters processed). That must have been a mistake, because thereafter the drive became inaccessible.
I booted my machine from the Windows install disc to access the Recovery Options / command prompt. From there, I tried to start chkdsk on the HDD once again, but it stated that chkdsk does not support Raw drives. Googling the topic of NTFS drives that are showing as Raw, there are a lot of articles, incl. a thread on this website (see here). Unfortunately, none of the suggested solutions have helped. Here's what I have tried:
- Using Partition Find & Mount from Hinder's Boot CD. This application saw the HDD, but only as an unrecognized device. After one hour of scanning, it had only completed 1% of the scan, so I cancelled it.
- Using TestDisk. This application also saw the disk. A quick scan did not find any partitions, so I started a deep scan. It continuously read erroneous values, so after over an hour of scanning, I stopped the scan in search of a better solution.
- Using iCare Data Recovery. I ran a scan for ~12 hrs and eventually stopped the scan. It found a couple of pictures, but the free version would not let me recover them.
- Using GetDataBack for NTFS. This does not see the device.
- Using a Linux Boot CD. I tried Linux Mint and I could see the device, but only as an unrecognized device that could not be accessed.
Unfortunately, after having tried all of the above, the HDD now doesn't even show up in TestDisk or iCare anymore. I still see it in Windows' Device Manager, but not in Windows Explorer. When I plug it into my computer, I can hear the disk starting to spin, then there is a beap, and the process repeats (spin-beap, spin-beap, etc.). After about a minute, the light on the HDD just starts blinking and doesn't stop. The disk still appears to be spinning.
Any thoughts on what else I might try would be sincerely appreciated.
