Recovering unallocated space of a USB flash drive.

Today I played with the latest SUSE Linux Live. I had not have a DVD drive and used USB flash drive instead. I wanted to reformat my flash drive, but suddenly found it that it had not been possible. The most of the disk space had been unallocated, and my Windows 8 did not allow me to use it.

Unfortunately Windows does not support Fdisk anymore. But there is another good command line tool to solve this problem. The tool’s name is DiskPart. I would say it is the next generation of Fdisk tool. DiskPart provides you information about your partitions and volumes, allows you to delete and create partitions, extend NTFS volumes, etc.

Let’s remove unallocated space. First of all run Windows command line and type diskpart in the command prompt. Windows will ask you for Administrator permissions to run the tool. Then run list disk command to find your USB flash disk’s number. It should be the same as disk’s number in Computer Management tool. It was 1 in my case. Next you should chose the disk to work with. Type select disk <disk number> command, e.g. select disk 1. The next step is to clean all volumes and partitions on the disk. Use clean command to do that. The last step is to create a primary partition. You can do that using create partition primary command. That’s all. You should be able to format your flash disk now.

This is how I removed unallocated space on my machine:

Microsoft DiskPart version 6.2.9200

DISKPART> list disk

  Disk ###  Status         Size     Free     Dyn  Gpt
  --------  -------------  -------  -------  ---  ---
  Disk 0    Online          298 GB      0 B
  Disk 1    Online         7509 MB  6619 MB

DISKPART> select disk 1

Disk 1 is now the selected disk.

DISKPART> clean

DiskPart succeeded in cleaning the disk.

DISKPART> create partition primary

DiskPart succeeded in creating the specified partition.

DISKPART> exit

Command line operations do help a lot yet for someone who is unfamiliar with command prompts, it is not so helpful. Besides, even in command prompts, you need to delete current partition and recreate one. In fact, this task could be done in graphical interface and within only one step with third party software, say AOMEI Partition Assistant Standard. Use http://www.disk-partition.com/features/extend-partition-wizard.html in the software.
