I bet your instant thought was a cheap no-brand one i got on trademe? no.
I 1gb A-data one I have had for so long that it originally cost me about $60 - $70
As a side note I know I can just buy a new 8gb one for about $12 and that is not the issue I am more interested in finding out why it is happening.
Anyway, It is only showing 170mb available space. I re-formatted it nothing changed. I opened the partition manager utility (windows 7) and clicked on the partition then clicked delete now it still shows it has a 170mb partition but even after removing and re-inserting the flash drive + re-opening partition manager the delete button seems to have disappeared.. what next?
