Hi everyone. After cleaning pc and redoing the cable management on my pc, i couldn't access or view my data on one of my hdds (1TB) and looked like this:
upload_2017-1-27_20-0-0.png

And whenever i try to access this message shows up:
upload_2017-1-27_20-1-5.png

So i'm wondering if there is any solution to this problem. Help will be appreciated.

Managed to access drive, but lost most of my data...
Best way to recover files?

is it a seperate hard drive, or is a partition on a drive that you can see?

Also, have you tried checkdisk on it yet?
 
its like it hasnt had a drive letter assigned to it yet almost, although i see it does....i might be dying. health check maybe if possible, oherwise remove, and maybe try a dock?? a tough one.
 
Please post drive SMART data. There are several utilities that will give you this, but the free trial of HDD Sentinel will work fine.

Hmm... one pending sector so the HDD is not "100%" but it certainly should not be behaving like this.

Interesting. It also gives me no idea where to go from here, sorry. Hopefully someone else can put the pieces together.

It's a separate drive, at least i managed to access to it

I did, but nothing happened
 
Recover data with Recuva. You'll need somewhere to store it. Then do a full format on the drive and the current pending sector should revert to zero.

Depends how damaged it is. It might, it might not. But the drive should be usable.

I'm doing that right now and i'll format drive after getting some of the data recovered

Thats not how that works.

Thought if you wrote zeros/ones to the drive it would allow the drive to reallocate the sector. I know that CheckDisk should do this as well, but it will sometimes get stuck and never get a good read from it to reallocate.

"There are two ways that the drive can finally reallocate the sector, and consume another spare sector:

.....

By writing something new to the sector."

No. You misunderstand. If the disk surface is damaged or faulty and fails to write to a sector it will create a reallocation event. Then it will mark the sector that it could not write too as bad.

Since the failure is caused by issues with the disk surface the sector magnetically or physically cannot be written too and smart flags it.

If you use a piece of software to force a 0 write too all sectors it is possible to trick SMART it will reset. However, this is manufacturer dependent. SMART may not mark it as a good drive until it has been written to successfully 10 times for example, instead of just one.

While zero writing a drive or using forensic software to attempt writes to a sector until SMART reads it as ok may make you feel more comfortable the drive is still fundamentally damaged since their is an issue causing the sector to not be written to to begin with.

Subsequently, this can work in reverse. SMART is only able to distinguish a failing sector after an attempt is made and it fails. Which means that if you have not already written zeros to a drive but decide to do it do too a failing sector SMART may even read MORE bad sectors if the disk is even more damaged than initially detected.

Sector damage and warnings should not be attempted to be reset out of good practice. If their is a damaged sector this is not a software problem, it is a physical one and the drive should be replaced.

I'm pretty sure that it's a read error that flags the current pending sector, not write, though if it can't be read then it also makes it difficult to write to as well!

Drives have contingency in case of bad sectors, and they are anticipated. The firmware will try to read the data on that sector and move it to one of the multiple spare sectors that it has. By doing a format, you are essentially telling the drive that you have written off that sector as bad and it is free to flag it and use one of the spare sectors for future writes. You're not 'tricking' SMART, just allowing it to carry out its intended function earlier: The current pending sector count will go to zero and the reallocated sector count will increase once this process is done.

Now, if the CPS count (or reallocated sector count) continually increases, that's when you know the drive is past hope.

Good practice in either case is to keep a backup of essential data.

Like you say though, if the drive itself has major problems and is dying, then of course there's nothing you can really do.
However, a single pending sector count doesn't warrant writing off the drive completely.

Well said! I love discussion!
 
What does the bios say about that drive? Im thinking the MBR may have been damaged. If the MBR is bjorked, your data is still there and good, and formatting will only make revoery of it harder. Afaik, you can attempt to fix it thru the Windows Recovery Console or try /fixmbr at the command prompt. I think some partition programs can do that too.
 
killdisk I believe has a data access tool to copy and paste to another drive
 
what do you see in disk managment?

@mosin40

Did you have a lot of stuff on "stuff"? According to the screen you provided, 921 gigs are free space. Not sure if it's something important or not, it's just that when my HDD was acting up after I copied about 2tb of stuff to it, it would "discard" volumes but it would still show me that half of it is full.

Yeah i had around 500gb of used space, but after that most of it disappeared... at least i recovered some of the important stuff

Bummer, that's why after I got the new HDD I kept the old ones just for back-ups, it sucks to lose data.

yeah it sucks, that's why i need to buy an external backup drive
