I'm running Windows 7 Ultimate on a laptop with a 500G HDD, and had all partitions formatted as NTFS. I do a lot of programming and LaTeX typesetting, both of these involves a large amount of reading/writing/deleting to a lot of small files, such as C++ library headers or LaTeX packages.

The problem is that frequently, when there is a large number of writing to files, the partition being written to often corrupts, the chkntfs e: returns dirty, where e: is the partition being written. I've re-formatted the drive, I've contacted the laptop manufacturer and had the HDD checked, the HDD is not faulty, there are no bad sectors, and I've tried a brand new HDD, to no avail. The other partition on the same physical drive doesn't have this issue.

So at this point I'm pretty sure that it's no hardware related.

I've searched the Microsoft support pages, one page provides an update for Advanced Format Disks, which I've already installed. The chkntfs log shows $130 index errors, and when the chkdsk ends I normally lose a lot of files. What's more strange is that some of the files that I lose aren't even being written to.

I'm at a loss here. Can anyone help? Thanks in advance.

What did you use to check the hard drive? – jmreicha Oct 17 '12 at 14:55
Just because the HD is OK doesn't mean some other piece of hardware isn't failing. I'd check RAM next. – afrazier Oct 17 '12 at 15:44
@jmreicha I used HD tune and I've sent it to the laptop service center to have it checked. – egwene sedai Oct 17 '12 at 15:59 the point where you know what a C++ header or an index error is, you probably know more than your computer service center's personnel, but I hope it works. – Zac B Oct 17 '12 at 16:00
@afrazier My system comes with 2G RAM, I upgraded it to a single 4G brand new RAM. This is hard to troubleshoot because it is not exactly reproducible. – egwene sedai Oct 17 '12 at 16:03
