$ sudo unmount /dev/sdb1 $ lsblk | grep sdb1 sdb1 8:17 0 1,8T 0 partĢ. Its recommended to unmount the disc before applying ddrescue. In that example, sda is my operating system and sdb an external harddrive. $ lsblk -o name,label,size,fstype,model sda 119,2G SAMSUNG SSD CM87 ├─sda1 512M vfat └─sda2 118,8G ext4 sdb 1,8T Elements 10B8 └─sdb1 Elements 1,8T ntfs Use lsblk to list all block devices attached to your system. You have to identify your corrupted device. Many paths exist to get your data back, like using the forensic data recovery tool foremost, but its a bad idea to apply a bunch of different recovery tools on the disc directly since that could worsen the disc’s state.Ĭreate a raw disk image containing as much data as possible and start from there. If you use a device or a partition as destination, any data stored there will be overwritten. Never try to repair a file system on a drive with I/O errors you will probably lose even more data. It is best that the device or partition to be rescued is not mounted at all, not even read-only. Never try to rescue a r/w mounted partition.

Information about detected bad sectors are stored in a log file that can be used to perform a re-read in a next run

Contrary to the well known dd command, it performs a smart copy algorithm that skips bad sectors and tries to copy all good sectors first.

ddrescue can be used to get low level access to the hard drive and perform a copy of the whole device.

What now? Recover as much data as possible! Create a raw disc image copy with ddrescue TestDisk tries to analyse and recover lost partitionsĪt the beginning the analysis on the failing device looked OK, but the process crashed each try without success.

ddrescue: Copies failing block devices like hard drives, CDs to file or other block devices.įor me TestDisk’s partition structure analysis algorithm failed because of too many corrupted sectors.

This procedure is quite easy actually and well documented. TestDisk: If the issue is caused due to non-mechanical problems, like when you got a corrupted partition table, then TestDisk should be able to recover the trashed disk.
