![]() ![]() One of the great strengths of DDrescue is that it is interface-agnostic, and so can be used for any kind of device supported by your kernel (ATA, SATA, SCSI, old MFM drives, floppy discs, or even flash media cards like SD). DDrescue also features a “fill mode” able to selectively overwrite parts of the output file, which has a number of interesting uses like wiping data, marking bad areas or even, in some cases, “repair” damaged sectors. That is, you don’t have to wait for an error, stop the program, restart it from a new position, etc. The basic operation of ddrescue is fully automatic. It copies data from one file or block device (hard disc, cdrom, etc) to another, trying to rescue the good parts first in case of read errors. If so, how do I determine the default location of the logfile?Ĥ.DDrescue is a data recovery tool. If not, what options do I now have to create one, interrupt, and resume?ģ. By using the simple command "logfile" after designating the source and destination drives, have I successfully insured that a logfile will be created or not?Ģ. I configured my commands as above based on a forum post, but then noticed other discussions showed people naming the logfile (logfile.logfile, or logflie.log) or even specifying the location for the logfile, which I wish I had known how to do.ġ. (and give drives time to cool down and rest) The problem is: I'm hesitant to do this because I'm not certain I created the logfile properly, and I don't want to lose my progress. I hope this will help with the speed of progress. I want to try to interrupt recovery now, reboot computer, then resume recovery. (rates dropping steadily over last day, but no stoppages or failure to read)(it has been unavoidable to use other programs on this system during recovery) Current stats: rescued: 493165 MB, errsize: 3316 MB, errors: 5304, current rate 8192 B/s, average rate: 1465 kB/s, time since last successful read: 0 s. It's been running 4 days now, and starting to slow down a lot. (over 2tb of actual data on source, probably around 2.5tb) Both source drive and destination partition are 3tb total. d to go direct to drives and leave them unmounted, -f because it was being finicky about (over)writing to my empty designated new destination partition. I used this string: sudo ddrescue -d -f -r2 /dev/sdc1 /dev/sdb1 logfile ![]() After extensive forum surfing and many false starts (why isn't there a straightforward step-by-step tutorial and good documentation on this important program anywhere?) and complete failure to get DDRescue-GUI to work, I managed to get the recovery underway. Symptom was drive slow to mount and change directories, certain files and folders started going missing or inaccessible.ĭdrescue seemed like the best tool for the job, but struggling with the commands. (I checked the SMART readout on the drive, and it displays "PASSED".) Not taking chances, I'm assuming drive failing, but may be some other problem. The source drive may be failing, but then again it may not. I'm a very advanced windows user, well into my first year in Linux, getting my bearings ok by now, but still very new to using terminal in advanced ways. Both the source and destination drives are connected internally to my tower, and neither is the os drive. I'm in the midst of a hard drive recovery using gddrescue on Zorin 9 (Ubuntu variant). ![]()
