Why is my HDD Corrupting While Folding?

post #1 of 14
Thread Starter 
Back Story
Ive had the original HDD for a year before it crapped out on me last year. That HDD had been on a couple different variations of my current set up. My SSD has my OS and a few programs, my HDD as everything else and the VM I fold with (Fold on the CPU only). In the last month a went from the same set up w/ a Asus Z68 Gen 3 to a Asus P67 Pro Motherboard and I got a new Corsair AX850 PSU. While on the Z68 everything was great, ran solid, was OC'd and was folding on it for an entire month. I then put the Z68 on a dedicated folding rig and put the P67 on the rig with the HDD that crashed (along with the new PSU at the same time). I had to RMA the first P67 because it wouldnt let me OC the RAM. SO then I got another and it accepted RAM settings at 2133. For the most part it has had the same settings as it did with the Z68 was on it.. (same OC settings)

What Happened
I had to take the folding rig offline for maintenance, so I folding on the rig in question for acouple days. It was giving me problems and at one point it say that I had an error on my screen and the "E" drive disappeared, I rebooted it with it plugged into a difference sata port.. It was running funny for the next acouple of days and by the end of the week I went into the cmd prompt and did a chkdsk on the E and found it was totally corrupt. So I got another one and had to fold on it last night. This time i decreased the bclk to its original 100 and lowered the OC. It was folding fine for 2 hrs while I was watching the walking dead on my computer at the same time.. Then the voices got funny froze.. The E drive dissappeared again.. Lucky it was only a corrupt file and I reformated it and its fine now.. But I am worried

What did I do wrong?
Ive been OC;ing for a year now and folding solid on the computer w/ the same settings for a month (while using the Z68 board), now with the P67 board I am having corruption errors? And even lost a HDD? I didnt really think a bad OC (lets say its a bad OC, even though I doubt it is) would affect the HDD..It didnt crash or BSOD.. I mean should I worry that anything I do that stresses or puts load on the computer could corrupt the HDD? How do I fix/avoid this problem.. (other than not fold on it or not OC it) I dont see why I would get these errors in such a time frame.. In 2 weeks I almost killed 2 HDDs?

I would appreciate anyone with advice could chime in and let me know what I should do.. ust hoping I didnt damage my components..

Wouldn't the first step here be making sure your memory is working properly?

edit- Then use HDtune to check the drive for errors that may indicate that you have a shoddy SATA cable?

Thats about all I can think of. Folding may be related to it as far as the fact that faulty memory may become more obvious through folding. However its ability to disrupt other files are not really a possibility. You can get corruption through a bad OC once again likely relating to bad RAM from the start that is more obvious due to the OC stress.

This is the order I would do it
memtest
hdtune test (pay attention to the SMART scores)
new sata cable
hdtune again if problems the first time

Dave, thanks for the response!

I dont know much about this area of trouble shooting.. Why would the memory aid in corrupting my HDD? I had the RAM chips for acouple weeks and was folding fine on the RAM (while also folding on the Z68 as well)

Is the HDtune a program to DL from somewhere or a cmd prompt function?

I got tons of cables..so I hope that is it.. Could it just be the motherboard doesnt like the RAM? Because I couldnt that RAM to Prime Stable in another other than 1333 on the first board.. Hence why I RMA'd it..

Is your system completely stable?

Memory/IMC stability can be very subtle, and can easily cause serious corruption. I was recently testing higher uncore multipliers on my setup and even though I passed several hours of linpack and prime95 I still managed to corrupt my SSD badly enough that I had to load a backup and start over.

An unstable memory subsystem is responsible for most corruption because everything that gets written to the drive passes through the CPU caches and system memory first.

Completey stable is hard to prove ;-p Ive done 18hrs+ of prime and still had a crash once..

And here I thought it would just BSOD before anything really happened and it would corrupt from the force shut down..

I dont know how stable it truly is.. Especially if stability varies from motherboard to motherboard, which it seems it is the case.. I memtested on the Z68 with the same ram and it was good.. I didnt do this on the P67

Now can I run memtest and prime and all the good stuff without worrying it will corrupting? I mean after 2 hours of folding it was starting to corrupt files.. I dont want to do damage to the system..

Would running all the tests off the SDD maybe stablize it? Or it would just run the risk of corrupting the ssd instead of the HDD?


Bottom line though.. ou guys are really thinking its a stability problem with the RAM? And its not defective products (cough motherboard cough) I like trying to blame the motherboard..

Yes memtest will not affect it as it is done outside of the operating system on boot so nothing related to the hard drive will be touched. RUn it with your normal OC and allow a minimum of 6-8 hours if you want a definitive answer about the ram. I know what you are talking about I have had several BSODs relating to corrupt files and I think my RAM may be on the fritz but have been to lazy to run memtest overnight. Although I have not yet had the incentive of a corrupt hard drive to do so.


I would hold of on folding especially if you have any info that is not backed up or would have major problems if you have to re install windows on your boot drive

Thank for the advice.

I guess I will run tests tonight. I really need to take down my folding rig to take out the H100.. But I guess it can wait.. Rather not risk looking the HDD.. On the last one it didnt just corrupt files but the whole unit corrupt and I couldnt even reformat it.. I needed to get a whole new one.. WARRANTY lol

HDtune is a program you can download, and the trial version will let you see the info you need in this circumstance. I would check the Ultra DMA count, if there are any at all I would change the SATA cable and keep an eye on that number over the next couple weeks to see if anymore pop up.

Memtest over night is not a bad idea to make sure your RAM is not being shifty, and even if it is fine I would up the VCCIO v just for fun because it isn't going to hurt anything running at 1.15 or 1.75v and will keep the IMC stable.

I would tend to lean more towards a bad SATA cable though, as you did not mention that you were running the VM in a ramdisk. If you are I would go with the memory as being problematic.

How does one run a VM in ramdisk?

I had the VCCIO @ 1.14 when it corrupted.. After I put it back to auto... Ill run the HDtune and I got some extra cables.. It could be the problem..I mean with my poor luck it could be anything! lol
