Several readers of our blog TS, sent me this problem that their pen drive is showing them less space than the actual. This problem was faced by one of our readers recently that I decided to write a solution for it.
The problem was that despite being the 4GB capacity drive, it showed only 900 MB of free space and was not storing data more than this. Even on formatting the drive, it could store only 900 MB of data only. If you are also facing the similar issue then here are the two solutions that you should try to make your drive work fine again.
Note: Data in the drive will be lost.
First Solution:
1. Plug in your pen drive
2. Type diskmgmt.msc in Run box to open Disk Management.
3. Select your drive’s partition.
4. Right click on it and select the option of “Delete Volume” in it.

5. This will delete the memory space allocated and free up the total space.
6. Now in the empty space created again right click and select “Create Volume” to create the space.
7. Select the file system and format the partition to be able to use it again.
Second Solution:
If you are unsure of the first solution or if it doesn’t work for you then try using this format utility called HP Format Disk Utility which is actually a low level format utility.
Use this utility to format the drive and it shall be working again normally.
Drop a comment below for which solution worked for you.

ok , none of them worked, i had an old 256 MB memory card, i don’t really know what happened to it but its now only 58 MB,
i tried both ways.the second didn’t work.the first> i didn’t find that “delete Volume” enabled, it was greyed out. and it was the same for another kingston usb drive
any other suggestions?

i can transfer the data in to my pen drive but whn i insert it in some other PC it shows that the file i have transferred in much much smaller than it’s size..
i.e. if i transfer a folder of 550 MB it only shows 325 MB..
By any chance is there any solution for such prblm?

We suggest you to try the second solution, as only low level format can solve the issue and fix the drive.

2nd one perfectly worked.
Problem i had
I have a 4gb hp v220w. But for some reason it was showing as 97mb.
Formatting did not work.
First solution did not work.
Second solution worked perfectly

Thank you so much.
2nd option works thanks a lot……….
2nd method will work for all hp pendrives………….thanks a lot…!!!it helped me.
try BOOTICE….
These two processes are useless,I did not find any delete volume option as it was enabled . Is there any option else to solve the problem.
The first solution did not work for me, as I had the “Delete volume” option greyed out.
The second solution did the trick. Thank you!
Thanks a lot it worked for me…
