hpt 366 generally has problems with 500 meg+ files
hpt 370 has the same problem but less frequently
Both of these may just be problems with ABIT's incorporation of these chips
as I have never heard of people having problems with off board cards with
the same chips.
It is also an intermittent problem which is worse but as I mentioned I have
only heard of it affecting large files.
