I've been trying to recover data on an external hard drive, but it has a lot of damaged sectors. I've run iRecover with the follow settngs: timeout set to 1000, retry attempts 1, avoid repeated retries checked, skip factor maxed to 2048. It took about 20 hours to run, but eventually the program hangs the entire computer. I've done this 2 times - a lot of time invested in this! Can't get it to complete so I can see the results
In this scenario it is a better idea to clone or image the disk. This way you only have to read the disk once. In iRecover, right click a physical device or partition and select the image file creation option.
I really want the photos and movies, so I ran "image recovery" - this time it completed
The image recovery feature is written with small device such as memory cards in mind. Using this mode on harddisks is not supported.
Here are my following questions:
1) is there a way to only scan about 30 percent of the drive only. The rest of the drive is pretty much empty and a waste of time and very risky to the hard drive since it's very damaged at 90 percent.
Yes. Right click a physical device and select 'define partition manually'. In that screen hit help for suggestions. If in your case there was only one volue on the disk, set start sector at zero and for size enter amount of sectors of the device - 10% (to avoid the bad area), or minus 70% if you want.
2) After an image file scan, you get a list of the files avail to recover. I saved these results. I tried to load this file again to see if I can recover the data without scanning the entire hard drive again, but the data is all corrupted. Why is this, when the files were not corrupted in the initial scan?
I don't know. If the disk remained unchanged then this shouldn't happen. I will investigate. Try loading a save file that was automatically saved instead.EDIT: I tested this and can't reproduce. I tried: Image recovery > scan (USB) hard disk > files intact (verified). Save internal program state and exit iRecover. Fire up iRecover, load previous state file. All data present and intact. Of course I have done this with a physically intact USB disk.
