Additional testing information: - Setting BIOS IDE mode to "IDE" does not solve the problem. It does reproduce a bit more random, but it does happen if the transferred data is large enough. - Re-tested with Ubuntu 9.04, with latest updates: Same Problem happens. - To rule out memory issues: memtest86+: no issues. Passed successfully - Power supply is brandnew and an "A" brand (Cooler Master). It is not overloaded. Measured this at AC. - Installed Windows 7 (64 bit). Sofar, no issues found, and already transferred 500GB+ data. (with Debian it crashes typically below 20GB transfer) Any settings to play with to make this problem disappear?
