This video is basically use command prompt. You use following ways to fix your usb flash dive problem.

i) You can use Device Manager to check the status of a plugged in but not recognised USB Drive by checking
if the "Universal Serial Bus(USB) controller" show up as working correctly or has a yellow exclamation mark on
it when the device is connected.

ii) In device manager down the bottom you will see "universal Serial Bus(USB) controllers" click on the plug sign
beside it which will expand that tree.You will see "USB ROOTHUB", Right clickon those 1 by 1 (keep all
your usb devices plugged in) and click on "UNINSTALL". When you have uninstalled them all shutdown

Fixed: USB drive unusable, unformattable, and reporting 0 bytes capacity
The drive properties show:
Type: Removable Disk
File system: Unknown
Used space 0 bytes
Free space 0 bytes
Capacity 0 bytes

The Volumes tab shows:
Type: Removable
Status: No Media
Partition style: Not Applicable
Capacity: 0 MB
Unallocated space: 0 MB
Reserved space: 0 MB

Opening the Disk Management component of the Computer Management console shows that the drive is connected, but there is no unallocated space to partition or format.

Other things about the disk look normal. It shows up in the Device Manager as working correctly, without any warnings, for example.

I Googled around and found that many, many people were running into this problem where the drive starts reporting 0 bytes capacity and can not be formatted. Of the dozens of pages that I read, no one found a fix for the problem. The most common solution offered was to return the drive to the manufacturer for replacement. Well, I wasn’t going to publicize my mistake and return the drives, I was going to repair them.

Software that didn’t help

Feel free to skip this part if you’re not interested in reading about the many dead-ends I explored.

I knew of one nifty program that had helped me out a few times before, so I tried running the HP USB Disk Storage Format Tool v2.1.8, but attempting to format the drive with this utility returned the following error message:

There is no media in the specified device.

Someone suggested using this thing called “Apacer Repair v2.9.1.1” to reformat the drive, so I tried that, but the software only reported “USB Flash Disk not found!” when I ran it.

Someone else recommended FreeCommander, but that failed to open the drive, too.


A number of people suggested attacking it with partitioning software, which I wasn’t looking forward to doing, but was willing to try.

Another last resort was going to be using the Windows XP Recovery Console’s fixboot and fixmbr commands, which got me out of a pinch when I screwed up a partition.

What I should have tried to begin with

Then I had an idea. I had a clean drive that had escaped my earlier bungling. I plugged it in, copied the contents to my desktop and tried to run the U3 LaunchPad software. Nothing happened, so I started looking more closely at the files. One of the files was called SanDiskFormatExtension.dll, which sounded promising. Now I just needed to figure out how to run the SanDisk installer to reformat the drive. I tried all of the .exe’s and .msi’s that shipped with the drive, but nothing wanted to run from the folder on my desktop.

Just as I was running out of options, I opened the autorun.inf file and found a very interesting entry:

The fix


I’m astonished that this information isn’t more widely available, particularly on the SanDisk support site and forums, as this 0 capacity problem seems to affect a good number of drives and there are many threads where this issue remains unresolved.


Otherwise, you can download the latest version of the U3 Launchpad Installer executable from the Sandisk KB.

Of course, if you’re not using a SanDisk drive, it’s rather unlikely that this software will fix your drive, but maybe your device’s manufacturer has something similar. There are also a number of good ideas in the comments below, so definitely read through them for more options.

If you’re trying to restore the drive’s contents or recover files, the all of the methods described on this page will format (erase) the drive and are not format.

this method works, tho first try to use in the Command prompt "chkdsk C:/r" of course substitute the C: for whatever drive your trying to fix and the /r means repair. and if your using this method in this vid be very careful to select the one you are trying to fix, your drive letters may be different than the ones in the vid.

Worked perfectly for me, thank you very much for the content. Keep up the good work. I wanted to detect an undetectable usb flash and no matter what kind of program I used or method tried, nothing worked. The steps followed by this guy's explanation definitely solved my issue.

this video uploaded 8 years ago, but today i got help from you, thank you a lot.

[saravanakumaarr]

Thank you so much for your video. It helped me a lot to recover my Pen Drive back. Usually, if we format using a format by right click over a removable device, it will format there by reduce the size of the Pen Drive too. Like before format if it is 14.3 then after format it shows 14.2 i.e. the total size. So, I decided to format via command prompt to save my disk space in my Pen Drive. Your video helped me a lot!! TYSM!! Keep your great work going on!!
