While running I was comparing number of identical files between harddrive and CD copies. Comparison fails randomly (~one out of 100 files of 560MB worth of files). Once file gets in cache it always fails if repeatedly compared. When it gets out of cache -- some other will fail. Sometimes bad copy is in CD, sometimes in HD. Once it gets out of cache -- doesn't fail again, but some other one will. Differences in files that I've spotted: from 1 to ~32 bytes continuously. What's unusual about my system: * I have SATA RAID disk array (2 identical disks Maxtor 6Y120M0/YAR51HW0, mirrored) (became supported only in 5.3 ?) * I run i386 on AMD64 * I have recent NVidia card, but problem happens even w/out drivers installed. Difference in copy of file coming from CD to my mind is telling that it's not HD hardware. And it's not memory: I've ran each of two 512MB memory cards separately -- happens on both of them. Looks like someone in kernel does a bad write in the memory. I know this is a tough one but I am lost with this problem. >How-To-Repeat: N/A >Fix: N/A >Release-Note: >Audit-Trail: >Unformatted:
