PC is a Dual P3 pentium 1ghz USB1.1

When I copy a directory from my PC hard disk, the files
MP3 files in the directory on the Archos are corrupted.

The symptom is the file will play for 4 seconds and then
the audio will stop, the time counter carries on, the red
light is on permenantly.

If copy the files individually or as say a block of 20 files
then I don't get the corruption.

Does the Rockbox file transfer suffer when the disk is
fragmented? Mine does have some fragmentation.
This task depends upon

Rockbox is inactive when the USB transfer takes place, it is
all done by the USB chip. Nothing we can do about it.

OK if you mean the USB chip read and writes to the disk, then
what could cause my problem.
The USB cable, the W2K driver what
If I just singularly overwrite the file the Rockbox will the play
it correctly. Today I had a file fail after 3mins 30secs,
corrected by resending the file.
If I play the file on the Rockbox from windows it is OK
PS I'm using W2K

afaik the rockbox doesn't have problems with fragmented files.
I would try transferring and playing while the box is charging,
it often helps.

I've gone back to just using the Archos s/w.
This also does exhibit some problems but it dosn't just sit
there with it's red light blazing doing nothing.
It recovers, theres a pause in the play and then it carries on
with no loss. So is the Rockbox s/w too clever? Why can the
Archos code recover itself?
