How to recover data from a rolled back and reformatted hard drive ?

SOURCE: Computer does not recognise Hard Drive

Hey guys. I have an answer on how to fix the Trekstor Datastation "Removable Disk" problem.

I also own a Trekstor Datastation 500GB and had the same problem even though it worked for several months then all of a sudden when I tried to hook it up to another computer, it stopped working. It would recognize the USB connection but you could not read the drive as it would say "Removable Disk".

In "Device Manager" it recognizes the drive as Sundata USB2SATA. But what it really should be is "WDC WD50 00AAVS-32ZTB0 USB Device" or something similar to that. For those that are wondering, yes, the hard drive is a Western Digital Hard Drive. Western Digital Caviar to be exact.

Solution: You need to open the cover to the hard drive and reconnect the hard drive to the connector on the board. It's that simple!

It is very loose and this model is not well designed so it can easily come off if you accidentally knock over your hard drive or move it to another location. The hard drive is held in place by screws on a holder where there is room for the screws to slide if the screws are not tight enough.

You'll need a T10 screwdriver bit to remove the cover and a Phillips screwdriver to adjust the hard drive.

NOTE: Doing this will probably voids your warranty but trust me, it works and it's really easy and quick to do. Took me 15 minutes.

Yes. This is going to sound strange. Put the drive in a plastic bag and put it in the freezer. Next day, take it out, hook it up, and see if it is recognized.

If so, under My computer, right click on the drive - click Properties - then Tools, then Error Checking. Check box Automatically Fix File System Errors. Let it run. If everything shows up, be ready to transfer wnat you want off of it.

Freezing shrinks the metal parts . Microscopically, but often enough to get stuck parts free enough to get working.

I just went through this with a 750Gig Book. now i have reformatted the drive (after transferring all over to new drive) and the clicking is gone and all disk checks are fine and i wonder whether to trust this device ever again... Hate to just throw out a large drive.

Dear,
Data can be recover but the drive must be accessible by OS. As you write windows vista says drive is not accessible and that the disk structure is corrupted and unreadable.Do one thing try the same drive at another PC. If it run on that PC copy the data to that PC. Now format the drive and paste the same data back to your drive. But, if same thing happend then there are chances of fault in the driveand for this you shuld visit to the service cetre but, they are not responsible for the data.

Thanks & regards,
Rakesh Kumar

Are you using a double power USB cable, which normally comes with W/D hard drives?

Also if the light on hard drive blinks the drive is not getting enough power from the USB port.

All the best!

If the HDD is not detecting in the BIOS then It’s seems like to be a firmware issue on this particular series of HDD
for Model: ST3500620AS Firmware: SD15 Barracuda 7200.11 500GBytes

The one & ultimate way is to contact the nearest seagate center in your location to get the data back up & if your drive is under warranty then mostly it will be free of cost. (Not Sure about it)
