If you read a sector 0 times, you are not reading it at all.
HAHA, took the words right out of my mouth.

Thank you very much for this helpful feedback! Great tool!

If that doesn't help, there's hardware problems with the disk hardware that crashes the system, and not R-Studio.
Another way is to create a disk image, and try to recovery files from it.
Thank you Alt! I am trying to follow your advice but after changing the value to 0 and pressing either "OK", "Apply" or "Set for all drives"
O is immediately beeing replaced by 1. With the up- and down-arrows, O is not even suggested (using R-Studio for Linux 3.9)....

It's usually best to clone the disk that has the bad sectors first using a tool like ddrescue in linux. Unfortunately any tool that runs in Windows will have limitations with handling bad sectors, it's just a Windows factor. Then run R-Studio against the clone and you're good to go.

Hello.

I just installed the eval-version of R-Studio. The disk to recover does have bad sectors. In order to prevent R-Studio to crash, "Skip Files with bad sectors" was selected.

After beeing able to recover many files, the popup "Files with bad sectors" is shown. Now, whatever selection is made (e.g. mark, or Cancel), the recover operation is aborted and the following messages are written to the Log:
"Read disk at position 12345678 failed after 2 attemps. Illegal seek"

After this message, the partially damaged disk does disappear from /dev and R-Studio has to be restarted.



- How can files which are related to bad sectors reliable be excluded from restore-attemps?

- Is there a way to have R-Studio listed all files which are related to bad sectors?


You help is appreciated. Thank you! Moses
