QPhotoRec takes forever in Pass 0: Reading Sector

#1 Post by ekardon » 18 Mar 2015, 19:57

Hi,

I have a corrupted 8GB, sandisk mini SDHC card. Few days ago, my android phone gave me an error to reformat my sd-card. I took it off and connected to my PC via adapter. However, it took few minutes before my PC recognized it. After I got a sound notification, I tried to access my files through "My PC", then, explorer.exe got freeze, and I couldn't open it.

I tried some recovery tools, but not a chance. I found this program, and tried. It got few minutes before it found my sd-card. I tried QPhotoRec.exe. While it was searching for sd-card, the program froze few times. It has been 66 hours now, and it's stil in Pass 0: Reading Sector part. It did not find any files yet. I started to wonder why this is taking forever? Is this even normal?

BTW, the program is often frozen, and takes some time to running again (3-5 secs "running", 40-60 secs frozen in a cycle). I have Win 8.1 Pro, 16GB ram, i7 4710q cpu and am using the latest version of the program. The screen as follows.

Please tell me what is wrong???

Looks like a hardware problem, you need to contact a data recovery company.

It didn't stop though? Well, I found the log file, and it seems it keeps getting this error "read err: read after end of file" each time. Any idea why and what does it mean? I am stil running the program, and attached the log file. I don't intend to send it to any company, as there aren't any important stuff, only photos.

So, would you at least try to help a little? What is going wrong and what else I can try? I haven't tried testdisk.exe for example. Are there any other options?

I think Im having the same problem as you, except mine has been running for 2 weeks now since I've been unable to get any help. I've restarted several times, but recently started taking screen grabs to track my progress:

I've got a 1TB drive:

The program runs to about sector 530,000,000 at normal speed then slows down to only a few sectors every hour. It appears the program is "stuck" since nothing updates, but then every 30 minutes or so it will find a new file. As you can see between the last two images (24 hours apart) only a few 100 sectors were processed.

Where did you find the log file, I can't find mine?

Seems similar, but you are luckier. You've been able to recover some files, I haven't. You say it stuck after some point, mine has been freezing all the time. You are using PhotoRec.exe, I use QPhotoRec.exe. I don't think, it is same though :)

Log file is in the same folder as my software. It's created when I started the software. It has the same name as my software, in my case: QPhotoRec.log. It's updating in each sector. However, I started PhotoRec-win.exe and had the following screen; and couldn't find any log files, even though it created a folder called recup_dir.1.

It's not a good idea to cross post with two different problems.

ekarden - As the admin says, it looks like your original media has a major defect, you will need to go to a specialist data recovery company to sort this out.

ag25 - It looks as there may be some surface errors on your drive holding your image - or maybe dd copied over errors from your original drive. I would start again using a different collection drive and image the original drive with ddrescue to try and reduce any corrupted data being copied over into your image file.

The drive holding my image is brand new.
The results I have a repeatable regardless of the drive holding the image.
The results are the same when running PhotoRec directly from the physical drive. I made the image only after I was having problems with the drive.

My drive was perfectly healthy to my knowledge. I'm doing recovery on an accidentally formatted drive.

Ah! This indicates that there are surface errors on your physicial drive. You need to use ddrescue to image the drive, then run photorec.

Okay, I can try this.

Is there site that can walk me through the process for a windows machine?
