Last night, I formatted the Pen drive using Windows formatting tool. Once the format was done, I pulled it out without using "Remove device safely".

Next time, I plugged in the device, the drive is showing up in Explorer.
But I am unable to open it, or format it.

enter image description here

I tried from Disk Management, by removing and re-adding driver letters. Still the same issue from command prompt

There is no volume selected.
Please select a volume and try again.

It's MoserBear 16gb pen-drive. Please tell me how to fix this?

Note: Used HDD Low Level Formatter, it's not recognizing this device.

can you right click on it -> properties? – Lynob Sep 3 '13 at 14:04
Step one: Remove drive from computer and drop it in the round container by your desk. Step two: Purchase a new drive from the rack by the checkout counter of the local grocery. – Daniel R Hicks Oct 5 '13 at 12:46
You haven't mentioned which version of Windows 8 you are using, 32-bit or 64-bit? – Firee Apr 1 '14 at 11:48

Open up the Start Menu and type “diskpart” in the run box. Press enter. You’ll be prompted by the Windows UAC to authorize admin access to the DISKPART tool.

A command-prompt-like window will open up, only the prompt will say “DISKPART”. At that prompt, type “list disk”. enter image description here

In the list output on our machine you can see the computer’s hard drive (119GB) and the removable SD card (14GB). It is absolutely critical you note the proper disk number. DISKPART commands are immediate and without any warning. If you type in the wrong disk number, you’re going to have a really bad time.

After identifying your SD card’s disk number, enter the following command “select disk #” where # is the disk number of your SD card. enter image description here

Whatever commands you execute after this point will only make changes to the selected disk; now would be a good time to double check you’ve selected the right disk just to be extra safe.

Next, now enter the command “clean” enter image description here

The clean command zeroes out the sectors of the disk that contain the partition data. If you wished to zero out all data on the SD card you could use “clean all” instead, but unless you have a pressing privacy/security reason for overwriting the the entire SD card with zeros, it’s unwise to waste the read/write cycles of the flash media.

After cleaning the disk, enter the following command “create partition primary”

enter image description here

The command, as the syntax implies, creates a new partition on the disk and sets it to primary. After creating the primary partition, the entire storage capacity of the SD card should be available to Windows. If we peek back into Disk Manager, we no longer see a tiny partition with a huge hunk of unallocated space, but a large partition ready to be formatted:

enter image description here

That’s all there is to it! A little DISKPART wizardy and the SD card is factory fresh again.

did you read my post? I pasted the error from diskpart. Please don't copy paste before reading the post – Reddy Sep 3 '13 at 14:26
@NitinGurram - The error message said you didn't select the volume, hence, the directions about selecting the volume. – Ramhound Sep 3 '13 at 14:54
@NitinGurram , alternatley you may try dban which can be used to wipe data from storage devices in blanking mode and get it in raw form.then you may able to partition it from within windows.Or you may give a try to dd if you are using any linux distro.but this may cost you some write cycles. – Ashildr Sep 3 '13 at 15:28
@DEFCON1, I will try it. – Reddy Sep 4 '13 at 4:54


enter image description here

Click on Parts Manage then you will find your partition then try to repartitioned it and then re-formating it.

THis will resolve your issue and again your USB starts working.

How old is the pendrive? Maybe it come the end of his life, and there is a hardware error in it. I had have the same issue 1 years ago and this program is easily recognise my damaged external HDD, backup the contetn of it and after successfully repair the MTB on the disk. But google is your friend I also tried tons of programs before find this. I hope you find some great tools which will solve your problem! – NoNameProvided Sep 3 '13 at 14:47
