No i have only windows defragmenter. I am not really sure if there are any such software that might affect the file system. In any case, i'll keep investigating and then see what comes up. Should i close this post?
Shane:
A lot of programs can mess with the file system actually :-) Defraggers can depending on how the work with the files and the file system. Partiotion tools and anything that works directly with the file system can do it. It is also easy for the file system to get corrupted if say a file is being written or the sile system is being updated and the system loses power.
Anyways at least you are working so you can marked solved and close if you like :-D

oh that rings a bell. this happened a year ago, so i don't remember the details in exact :thinking:
here's what happened : system crashed, could not boot . so I took it to my brother ( I wasn't so knowledgeable back then) and he formatted the c drive and installed windows for me. but what i noticed a few days later was that, one logical drive wasn't showing ( a 100GB drive with only a pictures folders- important) . it was like it vanished into thin air.
I took it back to him, he used a number of tools to recover that drive and couldn't. So i was told that ''since there is no important user folders on your system, I will reformat the whole thing ( i mean into a single drive of 500GB) and then partition it. It was then that new drives were created. After that they have stayed like that.
It's only been a few weeks since i decided that i should take care of my own system (not depend on others) that i have been finding these discrepancies. I am debugging them one by one and it's actually much easier to maintain my system myself .
So, back to the main topic, i think while recovering the lost drive, maybe some file systems may have been messed up. It could be one of the possibilities. I'm not definitely saying that that is the only cause.
But in order to rule out this possibility I will have to reformat the whole thing again after backing up some 100GB of data to an external drive, which I don't have.
Any suggestions? Oh by the way, I ran a hard drive test from dell and it failed the SMART test. I suppose it's a physical damage, but i don't recall my laptop having been dropped or anything close to that. If there really was a physical damage, I don't think my laptop would function the same it is doing. Ever since i started maintaining my system since few weeks ago, it's been a smooth sale and no performance issues in spite of all the errors.

Crimson

Almost all hard drives have a self reporting software on them call SMART, which is used to report any problems that it finds. It doesnt always work as a drive can die without smart ever reporting a thing. But when SMART reports there is a problem then most of the time you can count on it being correct.
In this case what is SMART complaining about? It reports a lot of different things. One of the things some of the drives can do is remap a bad sector to a good one. Most of the drives have a few spare sectors set aside, so when a sector goes bad it will get remapped to a good one. So sometimes you will see a bad sector and then it is gone. But 1 or 2 bad sectors is one thing, if more and more sectors are going bad then the extra sectors get used up and there is a problem if the sectors keep going bad.
