So, i think I may have a failing drive, and was wondering if anyone could confirm? If so, is there any solution to mediate the problem and prevent the drive from failing?
I ran some checks using the trial version of HD Tune Pro, the data is below:

DAMAGED SECTORS:

I am currently running an error scan, and will upload the results once it is complete.
Yes, and no. Yes, it's a warning sign and you should look to backup and replace soon. No, there's not an awful lot you can do to prevent it from failing. A hard disk is a mechanical device, and will eventually wear out.
Looks like it. I assume you have everything backed up (because running test on a failing drive is VERY VERY BAD).
Anyway, 30,000 bad sectors is a lot. If you are lucky (no grinding noises) the damage is limited to a specific area, but there is nothing you can do except save your data. HDDs are not fixable.
Exactly and while not great, 600+ days of usage is not that bad either.Quote:

Thankfully, it is only a data drive, and not the main boot drive, but I do have some applications installed directly on it (as my main boot drive is a very small SSD). If I do a full clone to external drive, then clone the external drive back to new internal HDD and give the new drive the same drive letter as the failing drive, will everything run exactly the same, or am i likely to run into problems after doing this?
On the back of that comment, i stopped the error scan...Quote:

40GB+ Program Files>same as the Windows folder, low priority.
150GB User\My Music & Video > usually replaceable, low priority.
30GB User\my picture > mostly not replaceable (unless backed up somewhere), high priority
10Gb User\My Docs > not replaceable, high priority.
So, basically treat any failing drive as potentially only going to last for a few more minutes and copy they high priority (i.e. originals you cannot replace) first.
And if the drive were to contain really valuable data and you are willing to spend £££s, don't even attempt that but rather find reputable data recovery place and send it them rather than potentially making things worse which later would mean having to spend more money getting it recovered or making it impossible to recover irrespective of price.
Yes, but only if you succeed in getting everything back perfectly, which is not that likely.Quote:

When it arrived, I fitted it, to an e-sata port, then booted the system with a linux live cd, and used ddrescue to clone each volume in turn. This is a tool that will read quickly in big blocks until it gets errors, then slow down and retry to try to get everything. I left it to run for 36 hours and at the end of that time it recovered all but 2mb from a 2tb disc. I then used ddrutility to parse the list of unrecoverable blocks reported by ddresucue to give me a list of affected files. Finally I took LVM snapshots of the affected volumes before mounting them, so that I knew I had a pristine copy of the recovered data before I let Linux fsck attempt to repair it.
Overall, my data recovery went well. In all about 300 files where damaged, but all but one where downloaded online and so easy to replace. I did have family photos and important documents on that drive, but they all recovered perfectly and in any case I have those backed up in multiple places. The only annoying factor was the expense of paying for a new hard drive when I was not planning to, and the fact that the faulty one was only a few months out of warranty. (A WD Black)
As all these recovery steps where done with a Linux live CD, you could do the same yourself if you feel confident with the Linux command line, Though as kompukare said just now, your drive could die permanently any time, so you need to prioritise getting copies of anything irreplaceable like family photos or important documents ASAP. I have also read that it is a bad idea to power off a faulty drive, because the initial spin up is quite stressful, so it would be better to leave your system switched on until you have recovered all the data you can.
Good luck!
Cheers for the replies, I am currently booted into an acronis boot disk, which is painstakingly cloning the faulty drive to an external drive, it's been running for about 2 hours and is 30% of the way through. Just hope it works!
Big drives take a long time to read even if they are working perfectly, because of the amount of data involved.Quote:

If it works anything like the Linux equivalents it will gradually slow down as it it tries to get the last bit of recoverable data, and the last few Mb will take several hours.
If it is still going in the morning, then just leave it all day, and see what it gets back. You have nothing to loose by waiting it out. You may as well get the maximum you can before the drive finaly dies.
Its going to take longer with all those reallocated sectors anyway, the sector seek time will be up. But there is nothing you can do to speed it up - just leave it to do the best it can.Quote:

Going to do a low-level format on it tonight, in the hope that it will buy me a little extra time (to get me through until payday, when I can buy a new drive!).Quote:

Hitachi drives have quite a good reputation for reliability. I'm currently using 4 4TB (HD7240 series) drives in 2 RAID 1 arrays. One pair has just over 9,500 hours, the other 7,800 hours. The system they are in currently has an uptime of 7296 hours. Not quite up to the usage your drive has had, but they came with a three year warranty, so I hope they'll be good for another 16,000 hours or so!
My standard reply: Look at the length of warranty. If the people that made it don't trust it, I won't trust it.Quote:

My home server has WD Red drives which I think are only 3 year, but they they are in a raid mirror set so seemed the tool for the job.
I don't know anyone that likes the Green drives. Slower, feels more like they are built down to a price.

But of course my experience doesn't mean you will get the same - which is why I use RAID AND ensure I take a regular backup. Any drive can fail at any time - statistics apply to a populations, not an individual item :)Code:smartctl 6.0 2012-10-10 r3643 [x86_64-linux-3.9.10-100.fc17.x86_64] (local build)

Sadly the current Toshiba badged variants seem to only have a 2 year warranty, but notice they are on offer today so nice price: http://www.ebuyer.com/393828-toshiba...ive-dt01aca100Quote:

haha no, sadly not, but I do have a spare 1tb external drive, which will now be used as my backup :)
Well, my new Toshiba HDD turned up over the weekend. After having let the back run from my old drive to my external for 1 day 14 hours(!!), I restored the data back to my new drive tonight...and so far so good! Everything seems to have migrated fine, not getting any system errors and so far have not encountered any corrupt files, think I have been very lucky. Cheers for all the advice!
Good - sounds like a success story! :)
