Why is it not possible to partition a USB Flash Stick?

By moongate · 8 replies
Dec 30, 2004
  1. I have a 1GB FlashStick from cnmemory de
    (The same as Lexar Jumpdrive)
    It came without any setup software!

    Because other vendors ship Software with their sticks to
    create a secure partition on a second partiton I would
    like to do the same using a commercial software.
    In order to be able to use the software I need two
    partitons on the stick.

    -- so far for the theory --

    First of all I used the windows andministration console to
    delete the partition that was already on the stick from
    shipping time.

    After that I wantet to create two partitions on the stick
    but the administration console only offered making one
    single partition over the whole size of the usb drive.

    To be able to use the stick again I did that.

    Now the funktion to delete this partition was greyed out by

    Frustrated and in need to handle the problem I bought
    Partition Manager 2005 from 7Tools/Paragon Software.
    This manager was the only one I found able to handle
    USB Flash Drives. Partition Magic can´t !!!

    Using this Partition manager I´m able to create whatever
    I want on the stick. The problem now is that after assigning
    a drive letter to one partition I´m not able to do the same
    with the second. Windows tells me that it needs a restart in
    order to finish the changes but when it is restarted the second
    partition still has o drive letter :-(

    How am I going to take care of this?

    Maybe there is someone who managed to have two partitions on one
    stick without using the software of the sticks vendor to
    accomplish this.
    Or someone knows such a setup tool that works with any stick.

    Neither cnmemory now lexar provides this for my stick, only

    Many thanks

    USB Partitions

    IT IS Possible to make partitions on a usb flash stick, i dont think RealBlackStuff actually understood what you where asking - Yes HP USB Boot tool will create a bootable flash stick - but that is not the question.

    The Question is how to assign a drive letter/make accessible a USB Stick's Second or Other Partition; And if there is a tool for it.

    - you CANT use HP USB Boot tool to make partitions accessible - it creates one large fat/fat32/ntfs partition - and will remove ALL of your custom partition work. (Probably not what you want)

    - I have had the exact same problem - How on earth do you get Windows XP Professional to Assign a Drive letter to a USB Partition. Linux and DOS both recognise the other partitions and assign drive letters automatically/natively.

    How I Created 2 Bootable partitions on a USB Flash stick.
    -I used BootItNg to create 2 partitions on my 2 GB Generic "My Flash" USB 2.0 stick.

    The Second Partition is not accessible from Windows XP. However Win98SE DOS and Linux(Fedora core 5) recognise Both partitions fine. and are accessible.

    The question remains unanswered. As far as I know it is not possible to make the second/or other partition on any USB Flash stick accessible in Windows XP. I have tryed the Administrative Tools > Disk Management - but recieved the same error that moongate experienced "the volume or partition is not enabled. restart to enable...". Restarting does not fix the problem or allow you to assign a drive letter to the partition as moongate pointed out.

    Any Help on the matter would be greatly appreciated; as this kind of information is few and far between. ive spent hours searching for a answer. hopefully someone here will be able to answer it.

    A good partitioning tool would be either partition magic or PART (oldskool!)

    It is possible. (not recommended though). Go disk control panel and disk management. You can do it from there.

    You need to be using a flash drive of 1 GB or larger, and of the more recent technology. For Partition Magic, you must be using Partition Magic 8.0, then with a valid license, you can call tech support to follow up on the issues. I don't think you can do a partition smaller than 55 MB with the partitioning software.
