    I need to program USB drives, in batch. Is there a tool for that?
    Basically, a box, in which I plug-in multiple USB drives, and the box writes
    to them.

    I need the same thing for CompactFLASH cards.
    If you happen upon that in your search, could you send it?
    Thanks. -mpm

    I have been researching for quite some time. There are some products on the
    market, but they are in the thousands of Dollars. I wish somebody comes up
    with a good and low-cost line. The market is there, the technology is not
    expensive. If I find something, I will write you. Please do the same.

    That actually sounds quite inexpensive to me, given how small I'd imagine the
    market is.
    The technology isn't, but paying for people to package it up and devliver it
    to you in low quantities is.

    Is this just something you want to do for fun, or is it part of a commercial
    venture? In the case of the later, how you compared how much your product
    price will have to change for the various options of automated batch copying
    vs. just paying someone to sit in front of a PC with, say, 64 USB ports and
    lots of time on their hands?

    But can you write to all 64 USBs simultaneously (or close enough so it
    looks simultaneous)?

    I would say it would be nearly impossible. I don't know of anything that
    isn't proprietary hardware and software driven that would write to that
    many drives. Most I've seen was in a Sun Enterprise 450 server that had 20
    SCSI drives but there again, proprietary hardware and software, not just a
    bunch of USB drives.

    Mmm... perhaps not. But I bet you could do 8, and cheap PCs are only what...
    ~$250/ea? 8 input KVM, 8 PCs, 64 USB ports... go to town!
  8. Just get a whole stack of USB 2.0 hubs, and a simple program which
    copies files to all connected drives.

    Each usb hub can only transmit to a single device at a time, many pcs only
    have one or root hubs, so cascading hubs won't improve throughput much

    Thank you. I think this is the way for me. I now have to find the program,
    or find the person to write the program.

    That is OK, because these drives are slow. So, the bottle neck is not the
    hub, nor the usb, but the drives.

    Simple shell script.

    Operator inserts drive.
    System detects drive., calling file copy script.File copy script detects
    presense of certian file, if present leave, if absent, copy and then
    "eject" drive.

    Computer Associates is supplying some of their software on USB modules,
    so they have to have a way to program them.

    Service to my country? Been there, Done that, and I've got my DD214 to
    prove it.

    Say Michael,

    Since you deal with a lot of machines that use freeware, what's your favorite
    free anti-virus program? I've only used AVG, and it seems OK, but I suspect
    you might have had more time to try out and evaluate some of the other options
    out there.

    Couldn't find a link to a free version of AVG the last time I looked at
    their Web Site.

    The best free (free, not freeware) anti-virus program is clamav
    (, or the windows version from It is
    not an on-access scanner, so it needs a little discipline if you are a
    high-risk windows user - but on the other hand, it does not slow your PC
    with useless repeated checking of uninfected files. Use it to check
    your incoming email, and to scan downloaded files before running them,
    and perhaps for scheduled overnight scans of your programs.
