disk failure?

Postby hhead on Tue Jan 01, 2013 12:55 pm

I checked my harddrive today in a fit of boredom using GSmartControl I'm getting lot of pre-failures? Should I be concerned. Its hard to find guidance on this....

Re: disk failure?

Postby homerscousin on Tue Jan 01, 2013 4:08 pm

I am certainly no expert at this, but I check my SMART values occasionally, and I do have a hard drive that is on its last legs still sitting in my drive cage. It is disconnected from power and I'm using my new one. I look at the raw values. Your drive shows a read error of 0, reallocated sector count of 0, seek error of 0, current pending sector of 0, offline uncorrectable of 0. This is good. Your hard drive has no errors and has none pending. I think that old-age and pre-fail is misleading and a poor choice of words.

My disconnected drive was giving me noticible problems. Writing files to dvd would would pause, the buffer would empty, the system would try maybe many hundreds of times to read certain sectors and write it to the dvd. I think my disk surface is ok, it is the read/write head that is tiring. Writing one dvd was usually ok, the second caused problems. The head was getting warmer and failing, I think. Any way, my pending sector count was in the 20's when I noticed something. It gradually increased to the 40's. My read error rate was in the thousands.

My drive was a problem, yours seems fine. Let someone else chime in for a second opinion.

Cheers mate. I agree the way its expressed is confusing. I looked into it a bit more and the normalised value is also higher than the threshold value which is good (in most cases). I'm not getting any errors. Happy new year.
