When I download huge files from the net (e.g. disc images), they
often come slightly corrupted. I have analysed the corruption in
detail (comparing the corrupted file with a known good one) and
find the corruption is allways a swap of bytes distant from exactly
12 bytes; This corruption comes seemingly at random, though very
often in burst of 2 or 4 consecutive bytes. Typical errors would be

Configuration
- MSI KT3 ultra2 (MS6380-E), Athlon XP2100, standard bios settings
- 80GB IDE Seagate HD (x2), ATI 8500LE, 1GB RAM
- Netgear PCI FA310TX (x2) 10/100BT Ethernet cards
- Window XP + all patches, standard drivers for
- 10BT hub
- cable modem (Motorola, ethernet interface, DHCP)
Corruptions occurs
- with several download servers
- with either ftp or http
- with either Explorer or Opera
- with either of the two 10/100BT Ethernet cards
- with firewall/connection sharing on or off
I never had any corruption with another computer (Macintosh)
hooked on the same hub/cable modem, thus believe the problem
is with the PC/Netgear PCI F310TX/drivers
Any clues?
