i have beed spending my free time on recovering my drive, that was unreadable one day. I do now know the reason why. So i have read and tried some stuff. have tried to restore some old drives for testing puposes. I used ddrescue and it done a very good job.
Now I get more question that i have answers to them while trying ddrescue on toshiba drive.
sudo ddrescue -d -n /dev/sdc /media/rec/640.img ~/Desktop/640.log
Press Ctrl-C to interrupt
Initial status (read from logfile)
rescued: 0 B, errsize: 0 B, errors: 0
rescued: 63663 MB, errsize: 36719 MB, current rate: 0 B/s
ipos: 100383 MB, errors: 1147, average rate: 440 kB/s
opos: 100383 MB, time from last successful read: 3.4 m
Copying non-tried blocks...
this is going for 3 days now... and it is quite interesting and I do now know what to think about it.
most when reading the from toshiba speed is between 700kb/s to 15M/s, then errors come.
it is like rule that for 1gig - 300meg is errors and this repeats all the way.
This disk is not so valuable so i am not thinking of going for the service somewhere. I am interested in DIY experimenting
any info on this would be appreciated.
