Hi guys, during the last weeks I tried to reinstall Win98SE on my ancient computer since it's gettting more and more unstable. But I experimented some strange hard disk errors when copying file around. Only the highest bits of a single dword is affected and reversed. This error occures from time to time - normally around 1-2 errors in a file of 200 mbytes. The places where the errors occure don't seem to follow a specific pattern. (I used two different hard disks: a Maxtor of 80 GB and a Smasung 160GB, but all partitions are within the 128GB limit). While copying files under pure DOS (with Win98SE boot disk... that uses BIOS functions to access drives), there are no errors! Under Win98SE this error occures before and after installing any VIA driver... If someone has an idea what could cause an error like that, please let me now!!! Cheers, div64 (I'm using an AMD Athlon XP 1800+, VIA VT8366/A KT266/A (epox 8KHA+) and 512 MB DDR)
