  1. My 1G flash drive can no longer be formated as it apears as a 256GB and the volume is too large for any programs I have tried.
    Please help

    What is the brand and model. Go to the website, and discover the rules for reformatting it. They occasionally do need to be reformatted, or you will ahve this loss of data space condition.

    The brand is Kingston USB 2, and every time I go to re-format the only size it comes in is 256G which is 256 times the actual size, if I force it in Dos to 32K it takes about 45min and once it's gone past 99% it comes back with error volume size too large.

    This failure is a common problem in certain Kingston and SanDisk flash drives. They do not warranty for this use in many of their flash drive models, but they will replace, without argument, the one you have if you have proof of purchase. You have to get a better card.
    Since most of the flash drives made are built by SanDisk (Samsung) or Kingston, then sold under about 87 different labels, you can expect to see the problem frequently unless you upgrade.

    I still have no success with it as it is a partitioning problem all PC's see it as 256G not 256M or 1G as it should be there for any formating attempted is of this large volume, I have tried many suggested programs and from dos partitioning as well and it still apears as 256G.

    Sorry to inform you that all Kingston Data Traveler series flash drives do not support for bootable function. We suspect that the USB malfuntioned after it was made to be a bootable device and regret to inform you that we cannot provide further assistance in this case, and we sincerely apologize if any inconvenience caused.
    Kingston tech support.
