utorrent: Data Error (Cyclic Redundancy Check)

I have been downloading a torrent worth 109GB data from one of the private trackers almost close to a fortnight now and halfway through the download, this error popped out of nowhere yesterday! :ashamed:

I wish I could take a screenshot when it happened yesterday but it looks something like this -

This happened on a Samsung N128 netbook with the WD5000BEVT 500GB hard drive. The laptop has not witnessed any random shut downs since it has a battery backup and most power cuts resume before the battery runs out of juice.

I did a quick scan for bad sectors using HD Tune on the drive and it showed no bad sectors. I did not have the patience to run the normal check though.

OTOH the utorrent FAQs seem to suggest that such an error has a possibility that the drive has bad sectors. I am clueless now!

I tried running a CHKDSK operation and it was taking a painfully long time to complete Step 4 of 5, after the reboot happened while running the CHKDSK application. I lost my patience and restarted the netbook! :ashamed:

ATM I am trying to download one file at a time from the torrent file - which btw is happening without the error being reported.

Did anyone here face a similar instance?
 
Painfully if the data in the other end is in read only mode.. this error pops us.

I had the same error when I was seeding long back

Transfer the file on another machine and check if download resumes? If yes with a minor data hit (ie 45% instead 50% showing completed), its a good chance the HDD has some issues.
 
^Yeah I am planning to do that once I am done with all those files which does not have problems with the download. Couple of them have completed the downloads as we speak. :)

Bang! One of my torrents which were seeding showed a similar error a while back and I resumed it and it hasn't shown until now. :ashamed:

Damn, WD is losing my patronage if the hard drive is faulty! :mad:
 
come on man... Swear it....I was seeding something i cannot share the info here... It was in 2007 and was using US @#$@#%!@#$

cause of power fail at low voltage might damage the hardware part due to frustration charge even i have 1000 va ups but the power fail due to low voltage output setting and my creative usb headphone blew up due to sound is not clearly and even i shut down the pc after 2 hour late cause i was sleeping at late morning :(

p.s it is getting worst at india has too much power problem might damage the electronic product that suck :|
 
^Arun the issue may not be related to power fluctuations - like I said before, the battery of the netbook lasts for close to 2~2.5 hours whilst it is downloading.
 
Actually, I had faced the same issue in the past and came to know that this is not a µTorrent error. It is actually an error reported by your HDD. It means that your HDD was unable to read/write the data because the sectors are starting to die.
 
^^ Yup, that seems totally weird.. :ashamed:

But since chkdsk fails to give any fruitful result, you can't do anything other than backing up your existing data and start clean by reformatting your drive.
 
CHKDSK is taking a painfully long time. Step 4 of 5 itself took like 15minutes to go from 0 to 6%. :mad:

Once I am done with this torrent, I think I'll have it RMA'd instead of losing any further data.

Bad Sector surely is one of the reasons for Drive failure, but it's not the only one. May be HD tune is not able to detect the error in your case.
 
use wd diagnostic tool to check the hdd. many times, hdd will map spare sectors on the fly to remove bad unusable sectors. so you will not find any bad sectors while doing checkdisk.

alternatively, go to the windows event log and see if there is mention of bad disk for hd0 in it. if yes then get a new hdd fast.

Thanks for the tip! :)

I am remotely accessing the netbook from work and have downloaded the utility and the drive passed the quick test and S.M.A.R.T status shows as pass whereas running the extended test shows estimated completion time close to 8+ hours! :ashamed:

Would it be worthwhile running the test for like that period of time?
 
I went through the exact same thing. Later I realized that my HDD was indeed dying. CHKDSK /r showed me that there were bad sectors. I have already sent the HDD for replacement.

EDIT: the quick chkdsk won't show you anything. You have to do chkdsk /r to force a rather exhaustive check.
 
^Ah so you were in the same boat once! :p

Did you get the replacement yet? I suppose your netbook also serves as the primary download rig?

Damn I need to backup the data quick! :ashamed:

See if event viewer reports bad hdd blocks too.

well sometimes if the wd tool comes across a really bad hdd, it stops even before it can complete the full test. no need to run the full test if it passed the quick test. i think the tool does a surface read/write scan in long test.

i forgot something here. Another great tool which is on the mark most of the time - speedfan. It has an option to check hdds (admin priv. req) It gives report in seconds and you can make out whether the hdd is close to dying or not.
 
use live Disk to chkdsk... else its useless... I always say that use live disk for chkdsk.. the System should have the complete control over the HDD to fix things.. not half control or less control.
