Re: [Dorset] Can I recover a Hard disk?
Perhaps run smartctl -C /dev/sd -a to see how long an extended check might take, plan to leave PC on for a little over this time and run an extended test: smartctl -t long /dev/sd monitor status with smartctl -l selftest /dev/sd PS, longest serving disk in my RAID: 61068 hours has no pending sectors or re-allocations.

Re: [Dorset] Can I recover a Hard disk?
Hi Peter, > I was then able to format the whole disk as NTFS. Given formatting and partitioning are, these days, just writing bytes that's the same as any other data as far as the disk is concerned, there is no difference between filesystems that means you can format it as one type and not another. It suggests there are sporadic intermittent disk errors, either in the media or the controller, and it's just pot luck what operation you're attempting when there's a failure. You could use badblocks(8) with either -n or -w to actively write then read to every disk block to try and show the extent of the problem. It would also allow the drive's controller to remap bad blocks onto, hopefully good, ones from its reserve store. The man page needs a careful read. > Conclusion: Success, and the disk will be OK for play, but don't be > surprised if it continues to degrade. Right. `smartctl -x /dev/sda' will show what the drive's controller thinks of the state of play.

Re: [Dorset] Can I recover a Hard disk?
Got it sorted! I used UBCD (Ultimate Boot CD) and it's copy of Gparted to attempt a recover of the disc, which showed me that it had been a Windows system. I was then able to format the whole disk as NTFS. For some reason it had not wanted to know Ubuntu, but now I was able to install Fedora 27 (KDE) which is up and running. Yesterday once I got it into a state where the head was continuously seeking back and forth (You know that sound when you hear it). This morning I was unable to run fsck on it because of something to do with LVM, but UBCD has a disk test facility that I have run. Yes there are some faults on the disk, and some parts that are 'pre-failure', but it shows that it has had 19000 hours of use. Conclusion: Success, and the disk will be OK for play, but don't be surprised if it continues to degrade. Cheers, Peter On 05/04/18 19:41, Hamish MB wrote: Sounds perplexing...

Sounds perplexing... You could try gparted's create partition table option (in one of the menus). Beyond that, maybe it's better to give up if its being that much of a pain - it may just be broken.
