TrueCrypt Question

I run Windows Vista and I encrypted my whole C: drive. Yet what confuses me is that how can TrueCrypt decrypt my entire Vista Operating System on the fly and store the whole thing in RAM so that it can run?

When I check my RAM, it says 1.03GB of RAM is being used, but surely the Vista Operating System takes up more than that to function and run

 

TrueCrypt doesn't decrypt/encrypt the entire disk in bulk during normal operation. Disk reads are decrypted and disk writes are encrypted as they occur. This happens as applications read and write to/from the disk. The data passes through the TrueCrypt driver only as it is needed.

 

Ok thank you for explaining that.

But I removed TrueCrypt and decrypted my hard drive, because I was running Sandboxie today and all of a sudden I got a BLUE SCREEN OF DEATH..something I have NEVER EVER had before, so it's definitely related to TrueCrypt.

 

If you decrypted and uninstalled Truecrypt, how could this be related to Truecrypt?
If there is a problem with decrypting a disk/partition, the decryption process hangs (usually caused by bad disk sectors).

Have you run checkdisk and defrag lately?

 

Didn't you make a disk image beforehand?

 

Let me explain again. I have never had a BSOD before. But a few hours after I encrypted my hard drive using TrueCrypt, I got a BSOD when browsing the internet using Sandboxie.

So I removed TrueCrypt and decrypted my hard drive and not had a BSOD.

 

I thought I had to decrypt the hard drive so it removes the TC boot sectors.

 

Not if you made one with boot sectors backed up as well before installing it.

 

I thought TC used different boot sectors to the one Trueimage backups?

 

The TrueImage backups would restore the original boot sectors, along with the original system (if you backed them up). What's wrong with that?
