Checking hard drive for corruption
    #18884817 - 09/24/13 12:57 PM (10 years, 4 months ago)

There's a possibility my computer may have suffered data corruption. Some of you may remember that I made a thread a few weeks ago about how my desktop kept falling over. Well, I was watching a movie I had on my computer, and there were a few gaps in the movie. It would just freeze, and the only way to resume it was to manually advance the seek bar. Moving it up about 5 minutes did the trick.


1. No other movie I had downloaded from this website had such a problem, and I had downloaded over 10.

2. I actually watched the movie a few days prior to when I noticed this. My desktop fell over between the first viewing and the second viewing. I do not remember if this movie had the gaps during the first viewing, as I was coming out of an Ativan haze during the first viewing.


Is there some type of program that can check the integrity of my hard drive? Look for drastic breaks in data patterns (this is what I imagine a 5 minute freeze gap would be like).

My biggest concern is my collection of rare music. One time I obtained a song that was corrupt -- a small segment, maybe about a second. So somewhere in the song was a messed up squeaky computer beep. And in an auiod editor this appeared as something drastically different from the wavy looking wave form. This corrupt segment was like a bunch of right angles.

If there's no program that can identify this type of stuff, I was planning on manually checking a whole bunch of audio files in an audio editor, making sure the wave form looked normal.

I also have all my music backed up online. So another option would be to download the backed up collection and do some type of data comparison, but I don't know how to do that. Could I create MD5s for the backed up versions and then test them on the original versions? I'm not crazy about the idea of re-downloading a bunch of music, though, so hopefully there's a more efficient solution.

Which operating system are you using, on your computer?

(NOTE: I'm not a computer expert: anyway I will try to help you, but wait for an answers from an expert before to ...do some damage)

-Windows : (did u try to run a chkdsk /f  when your computer is in the “safe mode”? If so, what's happened? ) you can try one of this programs :
http://www.techsupportalert.com/best-free-disk-health-monitoring-utility.htm

if you know what kind of hard drive you have: the website of its factory may have a diagnostic software. 

-Linux: ( I tested this procedure on my computer running Linux Mint; it should work on all Debian-based system,)

a) install smartmontools  :    sudo apt-get install smartmontools

b)identify your device:  sudo fdisk -l

(you should get an output whit something like :
/dev/sda1  *          63  699084539  349542238+
/dev/sda2      699084540  703277504    2096482+  5
/dev/sda5      699084603  703277504    2096451  82 )

then  -  sudo smartctl -i /dev/sda1 (in my example)

I get something like this:

Actually quite usable advice, OpenQwerty :thumbup:
A quick checkdisk and a SMART assessment would be the first step.

Also, OP, downloaded movies sometimes do this; they seize up somewhere halfway and you have to get past the rotten bit. Usually it's due to something going wrong during the encoding process or during downloading (or after downloading and reassembling the file, particularly if the source is a torrent or usenet). It doesn't mean that the hard drive is broken.

However, it's really obvious that you should make backups once in a while - that's just good practice. And of course, I warned you before about your desktop toppling over would damage your hard drive, so avoid that.

OP is the movie you DLed a DVD rip by chance? Sometimes they get "clippy" Try to dl it again. If it was being caused by your computer falling over you would notice more symptoms I.E. funny noises Coming from the drive etc. Try re-inserting your memory cards they may have been dislodged by the tip overs. always look at the simplest things first and go from there.

That won't do anything. If the memory modules would have been dislodged, he would have been facing more serious problems :wink: In the worst case, he could actually fry them with ESD if he's not careful.
No need to open up your computer case right now, OP.

Bullshit i've seen loose cards cause the freezing OP is talking about and if you ground yourself either with a wrist strap or on a bare or tile floor in bare feet it is almost imposible to short cards or boards. And yes loose memory cards will cause the symptoms OP describes , they may not be totally out but if they are loose and not making good connection . The computer may post but anything that draws on the memory can cause it to freeze. koraks  you should get a job with geek squad :lolsy: My sister went to them and every time they blamed the hard drive when all along it was an overrheating MoBo . OP if you can run a screwdriver it is pretty much a simple procedure to check this stuff. Though most likely just a "clippy" download .

Sure mate, you would know best. Concerning the geek squad job: funny you should mention that. I was in that line of work from ca 1995 to 2005.

Still nice you helped your sis out with her PC that one time.

That is great advice for linux. Ill have to remember that. Sudo -i to get root permission then smartctl and the help argument will give a ton of options on many uses for smartctl. Is this function included with all linux distros or in sone cases is sudo apt-get install smartctl needed after downloading it?

For op: if you are using windows opening cmd and using the command "chkdsk -f" or "chkdsk -r" is the method to check the disk for all errors on windows. The cmd will ask you if you want to restart the computer and of course you will because you dont want to scan the hard drive while the file system is mounted.

For linux the option to fix all disk errors is fsck, but once again you want to do this before the master boot records mounts the Os as it can damage the file system if files are in use while it scans and fixes hard drive errors

If I were you I would read every one of these links:

http://www.google.com/search?safe=off&ei=9I9EUoOANeTuigKd9oG4DQ&q=linux+option+to+scan+hard+drive+for+errors+command+line&oq=linux+option+to+scan+hard+drive+for+errors+command+line&gs_l=mobile-gws-serp.3...10596.17771.0.18343.17.16.1.0.0.0.642.7085.2-2j5j3j6.16.0.ekfns%2Ckfns%3D1000...0...1.1.27.mobile-gws-serp..10.7.2791.csRShIOfQQw

Extensively some include instructions to check memory hard ware errors etc. although the only real way to do that is trial and error

Really impossible to rule out anything with a computer problem. While certain errors almost certainly are related to certain problems, a black screen, blue screen, error message, message saying 'hard drive not found', computer turns, cant get internet etc. Its never a good idea to rule out anything. Always good to test in full:

Drivers, updates, registry(if windows), virus scan, disk clean, disk check, defragment, check ram, check psu, check graphics card, check core temperature, make sure all devices are securely connected to mobo interfaces, everything is plugged in, internet connection is solid, not too many processes running at start up, etc.

NONE of those are bad to do and no option should be ruled out. Remember: if its not broken dont fix it. If its broken test it all to make sure its fixed properly

No I just reflowed her motherboard The drives were fine but since the computer would not post the question of the drives was over ruled after they put 3 new drives in it in a month and still couldn't get it right.

I came to know that the only way to fix a hard drive corruption is formatting. Since I could not afford to lose a single picture, I couldn't go ahead with formatting. If you have other idea about hard drive please share your idea.

If your on a windows system you can use the "sfc" and "chkdsk" command line utilities.

When in windows explorer if you go into the options menu you can run some other drive checking utilities. If your using a non SSD drive, I'd recommend trying to defrag.

OP:  “GSmartControl is a graphical user interface for smartctl” (quote from its website)

….I have already proposed ( and tested ) smartctl for use on Linux systems (smartmontools = smartctl + smartd ). It should work, whit this  graphical user interface, even on Windows.  Do you still have problems like “gaps in the movies” ? Did you try whit Acronis Disk Director ? If so, what happened? Did u discarded the hypothesis  made by Koraks (

Check for damaged sectors... Usually when a HD goes bad, loading times start becoming shit, blue screens, etc. If it's a laptop and you move it around a lot, the needle in the hdd can actually scratch the surface its supposed to read. All hdds are destined to fail. Maybe it's time for a new one if things are getting really bad!

Thank you for pointing that out, OpenQwerty.

No, I never tried Acronis Disk Director's chkdisk-style bonus application.

The fact that the movie has those blank spots is suspicious, as I've subsequently downloaded many movies from the same site and never experienced such. I plan on doing a startup chkdisk, I've just been lazy about it.
