Yes, if you know the areas where it's broken, you can create an exclusive region on the disk and than image that region.

Hi,

Thank you, that's what I thought. Is it possible to jump over the broken parts of the disk, when creating an image? So, that if I know, where it will fail, can I jump over this part and continue imaging?

Best regards,
JM

Yes, it's possible to recover data from a RAID 5 when one disk is missing. You'll have to add a missing disk object to the virtual RAID you'll create in R-Studio. See how to add a missing disk in the R-Studio on-line help: Volume Sets and RAIDs at the bottom of the page.

Hi,

I'm in the middle of recovering data from broken RAID5 (WD Sharespace 8TB - 4 disks in total). I have extracted the disks and I'm currently creating images of those disks. It seems, that I can't image 1 of the disks at all, since R-studio gives me an error regarding hardware error after few minutes (and after few hundred MB's of image) and stops the process. One disk seems to be fully ok - no errors at all during the image process. 1 disk has few (9 errors until now - read error due to HW-fault etc.). Do you think that I will be able to recover most of my data? I haven't yet tried to take the image from the last of the 4 disks - which I hope will be ok.

Will I be able to reconstruct the RAID from 3 disks, of which at least one seems to be partially faulty?

Best regards,
JM
