Windows 7 CHKDSK reports "File record segment 3680 is unreadable" and then blue screens and reboots

Question

Theoretically, I understand the MVC design pattern, but in real life I'm not sure about the Model and Controller.
Basically my question is: What sort of code should each of them contain?

From what I understand it might be something like this:

• Model: Starts a connection with the DB, contains abstractions (objects) that represent the data, ORM, plus some kind of an interface (functions) for the controller to get or change stuff in the DB.
• Controller: The main program. Starts the web server, starts an instance of the model's DB handler, does all the logic with the models objects.

Am I missing something?

Solution 1

Sounds like there is a physical disk error on your hard drive.

Also sounds like one of the following things is going on:

• The Windows boot process may refuse to continue if boot-time chkdsk reports a physical disk error - in all my years I've never had the pleasure of seeing chkdsk report such an error so I've never experienced this personally but I would suspect it to be the case.

• The physical error involved may be on a critical system file that Windows needs to run.

The actual error reported by the BSOD may give more clues.

Disk errors can cause sudden slowness in the way you describe. Honestly I would get important data of that drive now by external means and replace it as soon as possible.

Solution 2

1. backup your files from ubuntu, reinstall Windows.
2. If 1 fails, you MIGHT have a faulty hard drive.

For you 1 is more likely than 2, it sometimes happens that you get corrupted segments. If you can't fix it with CHKDSK you must reinstall.

First check the RAM and the HDD (S.M.A.R.T). You can check the RAM with memtest86+. For the HDD I like to suggest you Hirens Boot CD (memtest is included)

Find out the HDD manufacturer, try their diagnostics/repair utilities and come back with the results.

Run Spinrite6 at level 2 to repair the faulty sector(s)...grc.com/intro.htm

A faulty sector does not necessarily mean a faulty hard drive. Spinrite6 repairs faulty sectors.

I didn't say it was a faulty drive, I said it might be a faulty drive.

[Robin Alvarenga]

Well, when you reinstall windows and format the disk it will automatically see the bad sectors and make it so that no data is written to them. However if that fails, it means that there is something else wrong with the drive than just some bad sectors. This means that drive will probably be faulty.

Then change your answer!

The model should only store the data. The controller is the one that should do the actual manipulation of the data.

Yes, what I described is more a service then a model (MVCS), but in most scenarios a service that provide data access is referenced as a model (MVC). and btw if you put all your data access methods in the controller you end up having fat controllers, instead a service will help you to share the same data access between multiple controllers.
