    Until you can build a working general purpose reprogrammable computer out of basic components from radio shack, you are not fit to call yourself a programmer in my presence. This is cwhizard, signing off.

    WindowsXP, but if there is a portable solution that would be great.

    I'd expect in reasonably modern hard drives (as in those designed for SCSI/IDE/ATA/SATA etc in the last 15 years or so), that the Run Lenght Limit is part of the firmware of the drive itself. You may find some information leading to it within the identication information for the particular device, but I'm not sure what purpose it would serve to know this.

    I don't think you can determine it trivially unless the manufacturer specifies it. Have a look at the IDE standard for "Device Informtation" or some such.

    OK, so if it can't be determined in software, I will just have to use a relational database referencing the drives model number.
