Monitoring disk access using gkrellm, I noticed that a command like cat /dev/hda > /dev/null shows eradic disk reads ranging from 0 to 80MB/s on an otherwise idle system. 1. Is this a hardware or software problem? 2. Is there a lightweight perf-mon tool (cmd-line) that would log this behaviour graphically?
