I have a 2GB Transcend pendrive. When I plug it in, it is detected by windows and it shows up in Computer>Manage>Disk Management. But it does not show up in explorer and it doesn't work even if I try to enter the drive letter in explorer.
Please, I'd love it if someone would help me out.
Screens:
The pen drive shows up like this in disk management.

But when I try to access it using the drive letter in explorer. It shows this message:

Is there anything important on it? You could try reformatting it through computer management.

Yes, I have tried different ports and how do I reformat it. It only shows up below in disk management not with all the other drives. Look, I've highlighted it....

It appears that it needs to be formatted. Right-click on it in Disk Management and format.

I can't seem to be able to format it by right-clicking on it, no such option comes up.

Your pen drive aside, your disk sure has a lot of tiny partitions... May I ask if it serves a purpose at all?

C - OS Partition
D - Software and design projects
E - Music and Games
F - Movies
G - Windows XP Partition
The last one is system reserved.

This is the only thing that it shows in the 'destination disk' dropdown list even after the pen drive is connected.

@Jacee - That doesn't work, I've already tried it.

BTW, when I connected the pen-drive on Ubuntu Linux, it showed up as a 'Generic USB Flash Disk', but it won't open up even when I try to open it. Here's what happens when I format it using MBR system...
