Hello Tanguy,

unfortunately I can't help you with your problem. 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 onl=
y
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 wher=
e
missing.
