Bugger....the little one actually decided for the first time in a month and a half to wake me up at 3 am instead of 8 am! Had tried to keep from getting up up, but to no avail.....
Shall try using a formatting program on the computer, already tried setting it to backup onto external through Rom manager but didn't make a difference unfortunately :-(
philz has posted a fix, but I'm not entirely sure that the fix is for this problem or not! Lol shall try formatting tomorrow, probably night, and will let y'all know how I get on, cheers
