Today I'm back after a long time with tips on repairing pen drive with disk space error. In this post I'll share my ideas on repairing the drive's with original size 8GB. In case of this drive it shows 200 MB size though it's of 8GB.

To correct this you can follow following process which works:

  • In this post I'll show how to recover a flash drive's full capacity using BootIce software.
  • Download BootIce, x86 0r x64 versions according to your OS from
  • Extract the .rar file into a location of your choice and run it. You can run it from flash drive or external HD as you need not to install it.
  • Insert your pen drive and select the drive you have with the problem. Deleting partitions will erase all data therefore be sure to back up any important files or data you do not want to lose?
  • Right click BootIce and select Run as Administrator as you will need Administrator access to run BootIce as it requires formatting privileges.
  • Select the destination drive and click the Parts Manage button from the dropdown menu.
  • A new screen will open, with the drive and any partitions beneath. Here you can modify parameters, such as partition sizes and Windows assigned drive letter. As in picture beside.
  • Select the main drive, the first option on the list and click the Re-Partitioning button.
  • In the popup window, select the single partition or multi-partition option depending on the partition(s) of the drive. In this example, we'll select the Single Partition option to restore the full usable size to the drive. Below, select the type of File System best matching with your drive, either FAT16 or FAT32 for pen drives. This one is FAT 32. You may assign a name for your pen drive in the Volume Label box. Leave all other options as default. Click OK.
  • A confirmation box will appear, to proceed if you are certain click OK. 
  • The popup window will gray out during processing and progress will be displayed in the title bar.

When finished you should see a confirmation pop up with successful message.

Now You should now see the correct drive size appear in My Computer.
