I would recommend it to anyone doing anything with hard disks, no matter if faulty or not. It’s not only for disks with “weak or bad sectors”. That alone is already reason enough for me to recommend against dd, when one can use the far superior ddrescue utility, instead.Įven then, it’s not the only thing ddrescue is better at, than dd. PhotoRec will retrieve your lost files even if the file system has been damaged or even reformatted. So, if you waited 30 days for the image to be created, but dd stops at 7TB of 8TB for whatever stupid reason, you have to start cloning the entire disk again, if you want to be extra sure, you are not missing data. USB memory drives, DD raw image, EnCase E01 image, etc. I’m pretty sure the article I linked states, that when an operation with dd fails for whatever reason, you have to start the whole process again. Since data recovery is usually read-only anyway, you would not need this extra security, when using the logic from your last post. The image thing is for additional security. The question mirrors this one from another. When I navigate to the partition I want and create image.dd, the only options to copy it are on the 120G drive. When I start testdisk I can see various drives. Gebe dort einfach testdiskwin image.dd ein. Shorter version: I've been using testdisk to recover data from a 120G drive with a number of partitions. So, if anything you do during recovery attempts would make things worse, you can return to where you started, just dd the (image/ another disk) back.Įven better if you can have a spare disk with the exact same model, size (sectors x cyls x head) - then dd your disk to the spare and do the attempts on the spare…ĭon’t do anything until you have an exact sector by sector copy of your drive, that hopefully still stores your valuable data.Īfter that I think I’d take testdisk, and give it a go.ĭon’t take an image, just use the hard drive as the source. Gebe cd ein und kopiere den Pfad zu Testdisk oder gehe ber cd (change directory) direkt in den Testdisk-win-Ordner. Or at least to an image file, if you have a much larger disk to hold the data. Meaning it contains a lot of other files. The very very first thing I would do is dd that disk to another, as a whole. DD extension (for archive images, not picture images) is not a single file, but rather an archive in the form of a file.
