    Some thumb drives contain a small read-only partition which contains optional encryption software to be used in securing data on the drive. If that is the first partition, the less flexible HMI bios may not recognize the data partition in second place in the partition table.

    That's getting above my pay scale. How do I check for that? Then again for the $s, I'll just buy a different brand.

    I use the windoze disk manager (Administrative tools -> Computer Management, click on "Disk Management"), for each physical drive, you should see a pictorial layout. OTOH, getting rid of them is usually a command-line operation, so you probably don't want to go there. (A different stick is much easier, if it works.)

    When you stick it into your computer, does it show you just the "hard drive" or does it show you a drive and a CD (read-only) device?

    Nothing read only.

    A newer model HMI recognizes the Lexars and while the older HMI may not use more than 4G, it does tell me the capacity of the 16G Kingston. Go figure.

    This is from memory, which makes it automatically suspect, but I think it has to do with sector size.
    IE: Old hard-drives (less capacity, ergo smaller sector size) will not be (are not being) recognized by newer operating systems.
