See the next section if you’re not sure which disk is mapped to which name.ĭdrescue uses fixed-position input (first) and output (second) arguments: ddrescue -v /source /destination This assumes that source disk is sda and that sdb1 is the partition to which you want to back up the data, so in your particular case they may need to be changed. To back up just the MBR of the disk (the first 512 bytes) use: dd if=/dev/sda of=/mnt/sdb1/saved/mbr.bin bs=512 count=1

If stands for input file and of for output file, and neither of them has to be an actual file (in the Windows sense) in the above example, /dev/sda1 is the first partition on the sda disk. It also has a data-recovery-oriented cousin called ddrescue, which basically does the same thing, but is more fault-tolerant.īasic dd usage: dd if=/source of=/destination The tool to move binary data from one place to another under Linux is dd. Using dd/ddrescue to recover (NTFS) partitions dd / ddrescue
DDRESCUE GUI LIVE CD DRIVER
When choosing a distro, the main points to check are if it has the ntfs-3g driver (as recent a version as possible, as it keeps getting better at a fast pace) and the ntfstools / Linux-NTFS suite I mentioned earlier, especially if you’ve used EFS to encrypt your data (in which case the only viable solution appears to be ntfsdecrypt from that suite, which needs the certificate with which the files were encrypted, which in it’s turn needs you to boot the (dead) machine, but it appears to be the only way to get the data back). As a sidenote, I haven’t managed to boot the GUI (X) of any of the distros, as my laptop monitor/graphics card seems to be uncooperative with the standard drivers/VESA mode, but apart from the visual partition manager, everything works fine from the console anyway. I’ve tried SystemRescueCd, Trinity Rescue Kit, RIP Linux and plain vanilla Knoppix, and Trinity Rescue Kit appears to be the best: it has ntfstools / Linux-NTFS installed, and it didn’t hang on boot because of the failing HDD (other distros did). As it turns out, to decrypt the files you need a certificate which can only be generated on the machine which encrypted the files, which is Linux live CDs with NTFS support
DDRESCUE GUI LIVE CD PASSWORD
If you’ve made the punishable-by-huge-amounts-of-pain mistake of using EFS and your disk crashed, as is my case, hope is as dimmed as the foresight of the folks who designed NTFS and used more than the actual user password to encrypt the data. you don’t use EFS for your most sensitive data, you’re pretty much off the hook. If you’re not paranoid about security (by nature or by job description), i.e. mount the images as drives under Windows and copy the files or be brave and mount the partition in a VM and try to actually boot it, at least as far as a command prompt (safe mode) or use a backup/partitioning tool to write the images to another disk.Boot off the live CD and use ddrescue to get a binary image of each partition or mount the partition(s) and copy the files to a safe place.Get a Linux live CD distribution which has good built in NTFS support (most of them have basic support by now) and ddrescue.almost dead, but not still “sort of” kicking), booting off a Linux live CD might still help recover (some of) the data. Nowadays, with very-much-improved NTFS support under Linux (and rather tolerant to faults compared to its native counterpart under Windows), it isn’t always so. Up until a while ago, particularly if the partitions were formatted with NTFS, the situation was pretty much hopeless.

At some point in your IT-enthusiast life you must’ve had at least one dead HDD, off of which Windows wouldn’t boot anymore.
