![]() ![]() See Wikipedia:Comparison of disk cloning software for their comparison. They contain complete system images from one or more specific points in time and are frequently used to record known good configurations. These applications allow easy backup of entire filesystems and recovery in case of failure, usually in the form of a Live CD or USB drive. Reason: This application list does not respect Template:App#Style and might be better as a table. Now you can check the file system for corruption and mount the new drive. The -i option may be used to instruct ddrescue to start reading after that position. In some circumstances the disk controller or a USB adapter may lock, while attempting to read a particular sector. # ddrescue -force -d -r3 -n /dev/sd X /dev/sd Y rescue.map Where X is the partition letter of the source and Y of the target block device.įor the second round, copy only the bad blocks and try 3 times to read from the source before giving up. # ddrescue -force -n /dev/sd X /dev/sd Y rescue.map For the first round, copy every block without read error and map the errors to rescue.map. To clone a faulty or dying drive, run ddrescue twice. The key difference is that ddrescue uses a sophisticated algorithm to copy data from failing drives causing them as little additional damage as possible. ddrescue is not related to dd in any way except that both can be used for copying data from one device to another. ![]() GNU ddrescue is a data recovery tool capable of ignoring read errors. Results may vary while using USB adapters. If possible, data recovery from disks should be performed using their native interface: SATA or, for older drives, IDE. See dd#Disk cloning and restore and Core utilities#dd alternatives. So, when moving data to a new drive, instead of cloning the block devices or file systems, consider creating a new file system and only copy the files (and their attributes, ACLs, extended attributes, etc.) with e.g. But before doing ntfsclone it is necessary to have a duplicate partition table of the HDD on the SSD.Tip: Over time file systems get new features and the mkfs utilities change their defaults, but not all new features can be enabled without reformatting. Then I started looking for NTFS cloning tools – turns out ntfs-3g has a utility called ntfsclone which does exactly that – it copies just the data, not complete blocks. ddrescue was showing estimated time as 17 hours!!! That too when the total data in the HDD is around 200 GB combined – OS (C drive) and Data (D drive). But copying 1 TB from a HDD which reads at max 100 MB/s to a SSD which can write at almost 1500 MB/s is surely an extremely slow job. So the first try was using a block to block copy, using ddrescue. Also you may need to adjust the commands to suit your system to select the correct drive and/or partition when copying partitions. If you are following this post, read it completely before attempting anything. ![]() You usually don’t need to install any extra packages, etc. To those who don’t know, SystemRescueCD is a kind of Swiss knife Linux distribution you can use to do all kinds of disk and OS recovery tasks. As someone who has done something of that sort many times, but with Linux based OSes my first thought was if I could do some sort of stuff with a SystemRescueCD running from a USB pen drive – as I wasn’t willing to use any Windows based backup solution since I had no idea how they work, or whether they work at all. So, I had an interesting problem at hand – to transfer a completely working Windows 10 installation from a 1 TB HDD to a 1 TB NVME SSD (Samsung 970 EVO Plus).
