Diagnostic Tools for Testing 2nd Hand Machines?
tom asks: "Buying second hand computers you always run a risk. I was wondering if the slashdot readers could suggest a toolbox of (preferably small) tools that you could take along with you on one or two floppy's so you could run some diagnostics on machines you would consider buying. I'm thinking of the checkdisks, benchmark programs, soundcard checks, USB checks etc."
Hard drive testing programs:
IBM -- Drive Fitness Test
Maxtor -- Powermax
Western Digital -- Data Lifeguard Tools Utilities: DLGDIAG
Seagate -- SeaTools
Fujitsu -- Diagnostic Tool
NOTE: Some of these tools may work with all drives, but this (free) collection should cover quite a few drives.
Just because SETI/RC5/etc push CPU usage to 100%, doesn't mean they fully exercise all the various units on the CPU, or even that they'll notice if a bit flips here or there.
