Re: Files copied to external hard drive are corrupted

I recently bought a Maxtor external hard drive for use to transfer
files from an older, space-challenged computer. I had no need for the
backup software, so I just plugged it in (USB 2.0) and Windows XP
recognized it as an empty NTFS drive. So I did a drag and drop of
around 75GB of files onto the new drive. The files are almost all RAR
archives ranging from 5MB to 50MB (the vast majority are around 10MB).
So we're talking about a few thousand files. The copying was fast and
went smoothly. Out of the 1000 or so of the copied archives I've
tested so far on the new drive about 9 or 10 of the archives were
corrupted. I checked the originals and they were fine, and when I
individually re-copied those archives on the new drive they ended up
fine... but it seems that invariably about 1 out of every 100 of the
archives copied during the "mass copying" is turning up bad. Is this
just a consequence of doing such a massive amount of copying at once,
especially over USB instead of a more proven interface like IDE? Or
could there be something more at work here, such as a bad external
drive or Windows screwing up? I've only had the drive for a few days
but all seems well with it; it's very quiet and runs cool.

If you put the drive on an internal position, is copying ok then?
(Always good to see if the basic parts work.)

I've heard of something similar, related to a specific combination of an Asus mobo with an nvidia chipset, and a misconfigured bios, where a setting called 'clock spread spectrum' was enabled by default.

Disabling this setting (required a bios update) fixed the problem in this specific case.
