This is a separate issue, but there is an elegant workaround for your problem. It is true that reading binary files is slow in Mathematica, but there is a MathLink package called FastBinaryFiles which completely duplicates the functionality of the Utilities`BinaryFiles` package, but does it orders of magnitude faster. This package is reference number 0206-783 on MathSource. You will need at least Mathematica 2.2.2 for Windows to run this; if you have 2.2.1 for Windows, you need to upgrade.

All I can say is that I had a similar problem with M. for Windows 2.2: I tried to read a file of about 128 kB byte by byte. Mathematica read only about 40 kB and stopped then without complaining. I realized it only because I wanted to process the data further and about 88 kB of them where missing.
