How to fix inaccessible flash drive identified by computer as "USB Disk 30X USB Device"

Having a bootable Linux on flash drive is very handly tool for a web developer. When I was about to create one, my TDK 16GB flash drive becomes inaccessible in my Windows 7 file explorer. The Windows explorer detected it and shows "Removable drive (H:)". When I clicked the drive, it prompted me to insert a disk in Drive H: as if it were acting as a CD or DVD drive. I checked it on my "Device Manager" and found my flash drive registered as "USB Disk 30X USB Device". I tried some known fix: uninstalled/re-installed the drive's device driver, re-assigned new Drive letter and nothing worked. I thought of giving it a low level format and in this article will show how to do it. Disclaimer: webfoobar assumes no responsibility for any data loss or permanent damage executing the following tutorial steps (use at your own risk).

  1. First, identify the VID (Vendor ID) and PID (Product ID) of your flash drive by using ChipGenius software and it can be downloaded here.
  2. Unplug all the external storage devices inserted in your computer then plug your inaccessible flash drive and run the ChipGenius. It will scan your computer for all USB devices connected in your computer.
  3. On the first pane of ChipGenius window shows the list of all USB devices detected, select the USB device labeled with the drive letter of inaccessible flash drive (in my case its [H:]). Below the first pane will show the detailed information of the selected device. Mine shows:

    Protocal Version: USB 2.00
    Current Speed: High Speed
    Max Current: 50mA

    USB Device ID: VID = 13FE PID = 1D00
    Serial Number: 000000000000

    Take note of the VID and PID.
  4. Identify the compatible software/util to format your flash drive. Go to and input the VID and PID of your flash drive. Mine didn't show any util available:

    VID=13FE PID=1D00 USB device list

    On the same page that list devices with VID = 13FE PID = 1D00, I scan other devices that have available util and I selected "Phison UPTool V.2070.0703 (Release)":

    Other device with util

  5. I googled "Phison UPTool V.2070.0703 (Release)" and found where I can download it: Download and extract the util.

  6. Execute the util (UPTool_Ver2070.exe). Click "SETUP" button, a small window will popup. Leave the "Authentication" blank and click "OK" button:

    Phison UPTool

  7. Click the "USB Parameters" tab and populate the VID, PID, Vendor Name, Product Name and USB Power Consumption fields. The VID and PID are important others can be anything (the USB Power Consumption can be found when ChipGenius display the detailed information of the flash drive earlier). Click "OK" button:

    USB Parameters

  8. You will be back in main window and click the big "START" button to start the low level format of you flash drive. After it reached 100% click "QUIT" button. Congratulations! your flash drive is now fixed and accessible.


I get "### Flash Fail 1 ###" where the flash disk is recognized on the software. It doesn't let me do anything to the flash disk.

@Tony you must have downloaded a software that is not compatible with your flash drive (the software can recognize your flashdrive but its program isn't built for your flash drive brand/model). Kindly follow the steps 3 and 4 above carefully.

UPTool errors @ 97% using this configuration and other configurations don't detect the USB device. Any thoughts on this?


Working! Thanks man, amazing tutorial!

Tu é foda demais cara. Existem diversos vídeos inúteis que dizem resolver o problema e não servem para nada. Muito obrigado por compartilhar seu conhecimento. Saved my 16gb pen xD . Thank you so much!

I watched a video and than read your article, both shown the same method, I could find a solution entering my USB's VID and PID information in but in the utils column, it shows "Firmware" which after a lot of searching on Google, I don't know what it is and where to find this kind of util. Please help me.

Hi, the full path is not just The correct page should have VID and PID fields.

USB was working fine until I tried to put Linux on it.
These steps to make it work failed.
The lesson is to stay away from Linux

I haven't tried installing Linux on a flash drive yet. If your flash drive become inaccessible because of installing Linux in it, the tutorial above might help fix again your flash drive. Just please follow it carefully.

thankyou!! I can use my old USB stick again after following this tutorial.

Thanks bro that's working !! i feel bad because i threw one a few years ago because it was not detected and i'm sure that the same software could had repaired it.

You're welcome. Maybe the new owner of the flash drive you threw already fixed it (by following my tutorial) and enjoying your flash drive now =)

Thanks dude, I had no hope with my Verbatim Store N Go and you helped me save it! Thank you so much!

Please read step #4. In this case, choose whatever your gut feel tells you (do a trial and error). Again remember as disclaimer webfoobar assumes no responsibility for any data loss or permanent damage (use the suggestion at your own risk).

Refer to step #4. Choose whatever you think will work (do a trial and error). Again remember as disclaimer webfoobar assumes no responsibility for any data loss or permanent damage (use the suggestion at your own risk).

Yes, it might. Or you do trial and error, refer to step #4 and choose another tool whatever you think will work until you find one that the start button works.
