Dear forum fellow members

Yesterday when I connected my WD 500GB Passport Essential into my laptop it said that I need to perform a scandisk. I took about 6 hours and I canceled at about 70% as it stopped on this 70% for one more hour. Nothing special happened, I was working on the external HD for couple more hours, plugging and safetly unplugging the device. Today morning I wanted again to plug my device, but when I plugged it it said that the device in drive letter H: must be formated in order to use it. I cannot do it because of very vital information on that disk ,especially pictures from my wedding, my book that I'm writing etc. I tried the thread recovering files for dummies by japp but the UFS doesn't find any files to recover, and what's more when I got Administrative tools->storage->disk management it says that the disk has RAW partition (why? from where? how come?!). I BEG You, please help.

System is : Windows 7 US Professional SP1 x64. Laptop is MSI EX628, but I tried on Vista 32 bit on my wife's computer as well as Win XP Home on my HP Mini 1000. Everywhere it says about formating, if I want to use the hd.

I also read about 90% questions here, people have similar problem to me, but even though I remember the times of Dune 2 and UFO : Enemy unknown...*sigh*... I don't know what does it mean when TestDisk asks me for Partition Table Type. As far as I remember shipped WDs have FAT32 system, so I believe I nad FAT 32 but was it Intel/Humax/or EFI GPT I unfortunatelly don't know. I have pictures from my wedding there my unfinished book and a lot of other documents (no games,no movies but still around 400GB of files diffrent types). I can say that I tried WD Data Lifeguard Diagnostic->Full Scan, but I didn't tried to repair the 3 bad sectors that it found, because it says that it will delete those files stored in those sectors, and I don't want to change anything on the HDD, to keep the partition stable.

I also found a tutorial -> but I just don't get it.

If you have somewhere to copy the files to you can probably recover your files by using a utility called recuva. Recuva is free and simple to use. Get it at the link below.

Testdisk is also an excellent utility and you should try to use it after you recover your irreplaceable files.

Now you can appreciate maintaining backups of any files you want to keep. In the future do not rely on only one copy of those files, no matter what the media they are stored on. IMO the most reliable media is CDR/DVDR. It also has the added advantage of being easy and cheap to duplicate for even more security.

recuva doesn't recognize the HDD, easeus on the other hand does, but works for 1 hour now and shows that it will finish in 93 hours. It's free to restore 1GB, but You have to pay for the rest around 39.99$. Anyway, I hoped for the testdisk,unfortunatelly still don't know to use it,as I stated before.

According to the WD site that drive came formatted NTFS. See the link below.

Seems like you should have all the information you need to run testdisk. The default cluster size for NTFS is 4kb if you are asked for that information. See the link below for more on NTFS.

One thing you can do to protect yourself. Get another 500GB hard drive and clone the original external to that drive. That way you have a backup if something should go wrong.

Western digital has free software to clone a drive on their site.

You are indeed very helpful :-) it works like a charm. Is there any option to define the files I would like to have restored? I don't need all those pdf and other stuff that needs to be recovered, only some doc's and jpeg's. 205h and counting till the end of the process is quite long time.

and one more thing : THANK YOU VERY MUCH OtheHill.

First of all thank You for Your time :-) second of all after 11 hours of analyzing my HDD by test disk I have.....35% analyzed. And I keep getting errors, and when I get those the analyze stops for about 30 minutes, and after that it goes further 1% more. Isn't it a little bit long time consuming?

here are the screenshots of those errors

Now when I'm writing that post it's 37%. And I cannot check the error type from recuva now, cause I'll have to switch off the testdisk analyze.

It is indeed very strange for me, earlier easeus also showed time like 100h before completion. Even if I ticked only to recover txt files,which are obviously small.

Unfortunately it sounds like your external is actually damaged. Testdisk works is a matter of minutes on drives that have corrupted or deleted partitions.

Perhaps you should switch to the file recovery mode. You stated above that Easeus seemed to work for you. Below is the link to Easeus and some other file recovery softwares.

The links are old so there may be updated downloads available.


PC Inspector (freeware)

Zero assumption Recovery
The demo is limited
It will only recover 'up to' four folders per run
But you can make multiple runs

not free

So now I have around 47% disk analyzed. I don't know how the HDD could get corrupted, by just lying on a table during the night. Should I wait for the end of analyzing? easeus is working as well, and I have a paid version, but as I stated above it also takes around 100h to finish (I didn't try it yet since it's around 4-5 days).I don't know if I should try different programs, as testdisk and easeus both show some really long times for recovering.

So I managed to recover most of the files, even jpegs in RAW foleders work, except from *.mov files. The raw mov files don't show any kind of movies, exept for the video lenght. Is it somehow possible to repair those files or are they doomed forever?

When you look at the properties of those files is the size what you would expect?

Was the original file type .mov, or something else?

originally it was .mov file and the sizes match perfectly. The name has changed however from DSC(number).mov to File(number).mov

Try renaming one of the files using the original prefix and then see if it will open.

So, you have recovered most or all of your files?

You should always maintain at least two copies of any files you want to keep. I suggest burning them to CDR/DVDR for the second copy. Disks are cheap and easy to duplicate for even more copies.

Use the external for your first copy.
