Hi guys.

I used unetbootin to try to get my sandisk 16GB usb disk to become bootable

it was def 16GB before but now my disk looks like it is 2GB and there is some 12gb that I can't get to

check this out:

I can't seem to delete the 2GB partition either

there is no options for the 12gb it is all greyed out

any suggestions?

Can you not merge the partitions in anyway ?

If not can you not format the drive and then do it again.

Try using Partition Magic.

Try extending volume L: to the maximum you can, the space is there it has just not been allocated to a partition.

I've formatted it but every time it keeps creating 2gb partition

ahh nada that partition magic don't work on windows 7 64 bit

on partition home my usb drive doesn't even show up
this is annoying what could unetbootin have done to my usb drive?

Its a non windows partition. You will have to run PM from either a boot disk or another non 64bit machine.

I've got windows 32 bit xp on my netbook
im sure it was giving me the same problem in there too

maybe i need to use fdisk in linux somehow

W_i_l_l · 28 Nov 2010 at 20:30

You could use gparted?

d_brennen · 28 Nov 2010 at 20:46

Run CMD, select the drive then fdisk?

psd99 · 28 Nov 2010 at 21:06

gparted on a cd is the way to go here.

It's been known for flash memory to be mis-sold, claiming to have a higher capacity than it actually does. I've also had flash memory go faulty in such a way that the available capacity decreased over time.

I was missold flash, and the way to test it is with h2test4_1.4 works for any writeable media, HDD and flash, works by writing data to the disk and verifying. Used it to prove a 16Gb drive was in fact about 800Mb. Got my money back but won't buy large capacity flash there anymore.
