Missed bytes on a hardrive can occur for any number of reasons.O/S limitation etc.
The BSOD's your getting are more significant.Take some time to give some particulars about your machine and the actual error message particulars.

Hi!

What means drive isn't reading 2gb? How did you determine it? Does it mean that you just have 20 GB partition for example and when trying to count space manually it became 2 GB less?

2 Gb is looks like a size of recycle bin... And what Anti-virus do you have? If it is any version of Norton AV, it requires to purge Norton protected files in recycle bin to free space (yes, it’s not convenient sometimes). You can do it by rt clicking to the recycle bin.
