Default Accessing data on external hdd

I have a western digital 1tb external hard drive. The other day it fell off the desk and the usb port came disconnected from the circuit board. The hard drive had 4 partitions on it with different sorts of data. I need to go access to the hard drive.

I also have a 2tb seagate external hard drive. What I was hoping I could do is take out the seagate hd and plug in the western digital one to get access to the data. But when I plug it in I don't see qny of the partitions. Is there drivers or software that will show me the data on the hd to copy it to yhe laptop?

What you have done generally works.

First step is to find out if the drive is physically powering on.
If the hard drive was in on or in use when the enclosure hit the deck then you are more likely to have damaged the disks or the drive electronics.
Can you hear that it is powered on in either enclosure? It is very unlikely that you will be able to feel it working but you might.
  • If it is not powering on then you can check the drive's circuit board to see if it is damaged - it might have visibly cracked solder or burn marks if it a component has fried.
  • If any of the disk platters are damaged from a head crash then you won't see anything wrong but the disk may not spin up. The worst case is that a physical disk recovery service will be needed to get them working.
Next step could be to try installing it in a desktop PC. You may need additional interface cables depending upon the disk drive type. You can also do it in a laptop but that will depend upon the drive form factor and interface matching the laptop drive.

Default Cannot Find lost partitions

I'm having problems with a external hdd. It's a western digital. What happened was it fell off a unit and the usb port broke.

So I brought a new external casing. Plugged it in but nothing would load. The hd is 1tb had 4 partitions. I looked to see if it was driver related but no luck.

I then looked deeper and it turns out when I use a hard drive program it said that it was all unallocated space. So I set about trying to restore the positions. I kept the space as unallocated and used recovery software to search for lost partitions. I have used 2 different software's done a quick search and full search neither could find any positions what so ever.

Do I have to create a drive and assign it a letter before I use the software? I did not format the drive at all. The partitions just disappeared...

It will be appreciated if you do not start duplicate threads for the same purpose. I have moved your latest post as a separate thread to this older thread. Please post here for further discussion on this issue.

Regarding partition recovery, you can try Easeus Partition Recovery freeware:

http://www.easeus.com/partition-recovery/

Please read its help and documentation carefully before proceeding. I have not personally used this software.

Sorry about the new thread, after i tried using a spare casing and not getting anywhere i then brought a new unbranded casing, i thought a different thread would be better.

The Hard drive does switch on and can feel movement. I cannot see any damage to the curicut board the hard drive itself looks in very good condiditon it was just the original casing that got damaged.

I think if i did create a new partition, it would have no problem working. But i would lose a lot of data i want. But i dont want any of the data getting overwritten when i crate the new parition.

Well, you had asked for partition recovery. Did you try the recovery software?

If you do not want to lose the data inside, then don't create new partition, or perform any activity, which will risk the data.

Try the partition recovery software suggested, or, try a data recovery software like Recuva. I don't know if it will work though.

Do not make any changes or write anything to the drive until you have recovered the data you want.


It is unusual for recovery programs not to find any partitions or data to recover. That suggests there is another problem. Try another recover program or two. If none find anything then gives us more detail. What disk drive is it: brand, model number, etc?

Does the size of the unformatted physical drive show correctly? 1TB should be about 1,000,000,000,000 bytes. If the physical drive size is significantly different then the drive is not being recognized correctly. Remember that the unformatted size is larger than the total of the sizes for the formatted logical drives.

Hi i have now tried quite a few programs. (they take about a day to do a full search)

I used Mini tools, Partition wizard and easeus partition-recovery.
None of them were able to find any paritions. They did however tell me that there was 931 GB of unallocated space. Not the full 1TB. Ther circuit board seems to be fine no sign of any damage.

When i ised Mini Tools it looked for lost/damaged paritions, when it didn't find any it looks for files, all of my files documents, pictutres, videos and iso files it did not find any of them. Im wondering if they would be in the 69GB that is unacounted for..

Do i risk formatting it then looking for deleted files?

This article explains why you only have 931GB.
So there is no space unaccounted for.
It's likely the HDD got corrupted from the impact when it got knocked off the desk. Sadly your only hope of recovering the files would be data recovery software. Formatting the HDD would only make recovery even less likely.
