Hi everybody

I have a samsung 500G external hard drive partition into 4 parts,  some times when I try to open folder in side it pops out something like can't be open, I run chkdsk in win7, and it turns out to be readable again.

Last weekend there's one folder I can't even use chkdsk to scan though, luckily the folder is not so inportant, so I backup all other files in that partition and try to format that one, and it can't be format with a fast one, so I try the low format, when it finished the whole partition can't be read, said it is not formated then I used fast format to format again try to solve this, tragedy happened, all the partition turned into raw, can't be deal with any way I know, I replug it again, the speed of entering My Computer becames very low, and seems there's something wrong with scanning the external hard drive. But one partition came to be readable but with a lot of crrupt files when I try to backup it, the other there can be even be read by win7.

I search on internet found out this web site

http://html5.litten.com/how-to-fix-external-disk-drive-suddenly-became-raw/

by James. He is pretty good described all the detail when I try his way with the deep searcher at first it when pretty smooth, but it turn out to be very slow soon, it move little over the whole night stay in 7%

then I tried his way with mount the hard drive partition, it can be mounted but no files inside

I really don't know what to do now, I have a lot of important file inside, and family pictures, it's hard to just give it away.

Is there anyone who can help me with this problem.

Thank you very much

If you are using Parted Magic click on DiskHealth and check the Smart status of the drive. Check the attributes tab for any failed attribute. Are there any failed attributes shown?

When you used TestDisk, did it detect any partitions using QuickSearch?

So when Quick Search detected all partitions, you highlighted one of the partitions, pressed the "P" key, and it did not detect any files?

You were able to recover the files from the good partition?

 

At this point I think there is only the option of recovering files using doing a scan of the hard drive. I would first copy all the files from the good partition if you not done so already.

 

There are four options. Free, paid (not very expensive), paid (expensive) and professional data recovery (very expensive)

 

The free option is PhotoRec, part of Testdisk. I would download the windows version of Testdisk and unzip the folder to your desktop. Run Photorec (It should detect the attached external drive) and let it scan the drive. The downside to PhotoRec is that all file names recovered are generic with the correct extension. You will have to open the file and see and rename it. The files are recovered in real time so you have to have space on the recovery drive that equals the data size on the external drive.

 

If the scan looks like it will take forever to do, stop it because you do not want to stress the drive more than needed. I would then look at going to a professional data recovery service.

 

The paid (not very expensive) option is using Active@filerecovery using the SuperScan mode. It is $35 with the promo code but you can try before you buy to see if it can recover your files.

 

The paid (expensive) option is using DataInternals Partition Recovery. This will scan the drive and try to create a new partition table. It's $150 and is also try before you buy.

 

The real expensive option is using a professional data recovery service. You can try these other services and get a quote,

Hi John

I rerun the testdisk deepseach really seems is going forever, and when press p two partition is "Can't open filesystem. Filesystem seems damaged." the one I formatted can be open and just one system file folder in side. and the last one with files in side,  when I try to copy files form the only good one ,it seems many files is corrupt can't be even open rather than copy.

I will try the free one first to recover the pics, it's the most important one

thank you very much!

I would use version 6.14 and not the 7 beta if you are using the Windows version.

The reason it picked  recovered the dll files is because you probably had that checked for recovery. There is an option to check which files  you would like to recover. As far as the number of files. I am not sure. I never had to recover that many before. Are they in directories labled recup_dir.1, recup_dir.2? Were any of your files corrupted or were they okay.

 

If possible I would suggest you rerun PhotoRec but in the file recovery options only select the extensions of your most important files. You can do this under FileOpt at the bottom of the window.

PhotoRec_files.png

 

Edit: It may be that is all PhotoRec can recover because of the bad sectors on the drive.

 

Edit Edit: If the data is very important to you, it may be better to use a professional data recovery service if it is in your budget to do so. Or see if the DiskInternals Software I linked to can do a better job, but I think the problem is you have many bad sectors on the drive.

 

197 Current_Pending_Sector  0x0032   012   012   000    Old_age   Always       -       7240   7420  is very bad.

 

The RAW_VALUE of the Current_Pending_Sector value indicates how many of the hard disks sectors can no longer be read and are waiting for re-mapping
