ReadyNAS 314 - a year of hell and now lost 10years of data!
I bought a ReadyNAS 314 when they were new in the market back in April 2013. I bought it partly because I wanted to safeguard my increasing data storage with redundancy in case of disk failure, and al...
Ok, got 2 new identical disks today.
Booted with Knoppix RescueCD
Connected disk 2 from the ReadyNas and a new disk to machine
Ran ddrrescue command:
ddrescue -r 1 -a 10485760 -b 4096 -d -f -K 65536 /dev/sdd /dev/sde btrfslog.txt
All was going well, or at least I think it was - I have no idea how this should go successfully.
Phase 1 (Copying), ended something like this:
rescued 5GB, errsize 380GB, errors 320...
Phase 2 (Trimming), started but then the disk started making that horrible clunking noise continuously, after about 20mins of numbers and the disk position moving around (I thought it was making progress) it did this:
rescued 16GB, errsize 2984GB, errors 38455...
When the last succesful read hit 15mins I pressed control+C to stop ddrescue but the disk noises continued. Eventually I unplugged the drive, it was very hot, and waited for it to cool down. Now cannot get it to be seen by the OS when connected back up :-(
So, was it working ok and I'm impatient? are those results awful and I should give up on this disk? Or is there another way?
