Disk problems?

Question

NTFS

One day TortoiseSVN started throwing an error intermittently:

Can't move '!nLog\.svn\tmp\entries' to '!nLog\.svn\entries': Файл или папка повреждены. Чтение невозможно.

Then I downloaded the console version of svn, the same error.
Also, Windows started to issue a message in the tray, something like "[svn.exe] disk access error, run chkdsk"
I ran it chkdsk /F /V /R /X /B, it did not find any errors.
I ran svn up in a loop, it turned out that the error occurs in about half of the cases (that is, not guaranteed).
For some reason, this problem only occurs with svn, it does not occur during normal work (eclipse, Visual Studio, uTorrent, browser) (or do other programs transparently retries?).
Also (I didn’t attach any importance to this, but perhaps there is something in common) sometimes it happens that the system and all programs “freeze” (not simultaneously, but when accessing the HDD), the HDD activity indicator goes out, after about a minute a click is heard, the indicator lights up and everything continues to work.
From what could affect access to the HDD: Kaspersky Crystal is installed, TrueCrypt (with encryption of all partitions, except for the one on which the error occurred)
There is a suspicion that the trouble is with the hardware, but the laptop was bought only 4 months ago.
Well, actually the question is: what is the cause of the problem, and, if with iron, then how to check it with little blood?
UPD:
SMART says everything is ok, except Spin Retry Count: screenshot
Checking the disk for errors with HD Tune Pro did not reveal any errors.
There were problems with the temperature, it rose to 67 degrees, while the recommended one was up to 60.
However, after a night in the off state, errors like “The file or directory ... is damaged and cannot be read. Run the CHKDSK utility" when starting svn keeps occurring while the temperature is already normal (46 degrees).
If I copy the entire directory tree to the root of this partition, then svn up will run without error.
UPD2: memtest86 didn't find any RAM errors
UPD3: Western Digital's native utility: Data LifeGuard Diagnostics didn't find any errors either.
UPD4:
The cause of the first problem ("crashes" of the file system when running svn) has been found out!
It turned out that this is not a physical problem with the disk, but a Windows 7 bug, if anyone is interested - here is a discussion , a hotfix was also released . After installing the hotfix, svn works fine.
Whom to believe now, even if the system is lying?!
The second problem (periodic disk shutdowns for a minute or two) has not yet been sorted out, but it is probably simply cut down to protect against overheating (although it is customary in such cases to reboot the computer spontaneously, and not suspend the screw for a while). Well, the cause of overheating is probably a crappy assembly of the computer. I installed a temperature monitoring program, but since then there have been no spontaneous shutdowns.

Answer 1

I think the problems are related to IRQ.

Answer 2

Unfortunately, I can’t say about errors and svn, but
“sometimes it happens that the system and all programs “freeze” (not simultaneously, but when accessing the HDD), the HDD activity indicator goes out, after about a minute a click is heard, the indicator lights up and everything continues to work "
Similar symptoms in me 1 time foreshadowed the smooth dying of the HDD. To calm down, take a look at SMART, and it's better not even to test the disk for a long time.

Answer 3

There is nothing wrong with SMART, but it is not a 100% indicator. Externally, the disk is clearly dying. If you do not want to change it right now, then at least back up important information to external media.
