| Unboot a bootable pendrive| Retrieve full size from bootable USB |
After the releasing of latest Ubuntu (14.04), I made my USB
(pendrive) device bootable with Ubuntu 14.04 OS using Power ISO software for
having a try.
The pendrive used was with capacity of 32 GB.
After installing Ubuntu on my PC, removed the pendrive and
connected it to my laptop which runs on Windows 8.1 OS.
But unfortunately it shows only 2.25 MB of total size but the actual
capacity of my pen drive was 32 GB. I was shocked and formatted my pendrive
many times for retrieving my lost space but still it shows only 2.25 MB of
space.
Soon after, I found a solution for this issue, and the solution
is, We have unboot the pendrive or any USB device once made it bootable if we
need again for storing other files. Windows command prompt can be used for
this.
Steps for Unbooting a USB Device.
Start Administrator's command prompt. For this,
Windows 8 users, press Win + X and then press a.
Windows 7 and lower users, press start button and search
for cmd then right click on it and click open
as administrator. A black colored window will be opened.
Now we need to enter into disk partition by,
Enter "diskpart" command on your
command window.
Now, in Diskpart, we have to list out the available discs
connected to the PC by,
Type "LIST DISK" command.
This command will list all disks available in your PC including your USB device
and note it's disk number.
Now we are going select the USB device from the disc list by,
Type the command "Select disk <num>"
where <num> indicates the USB disk number seen on the disc list.
Now type "List Partition" Command to list our all
available partitions in the USB disk.
For every one of them, type: "Select Partition <num>"
where <num> is the partition number and "Delete partition".
After selecting and deleting all partitions, make sure the the disc
doesn't contains any partitions left by type the command "List
Partition" again.
If there aren't any, create new partition using "create
partition primary" command. If it asks size just use the default
value.
Now type the command “format fs=fat32 quick”.
It’s Done
