iPod Broke

It appears my iPod is knackered. I tried several times to Restore it using the Updater software and I eventually got a message saying "Disk Write Failure". I reported this to Apple and they are gonna send me abox to send it to them. I carried on trying to fix it though and eventually it Restored it but its now only got 15.9GB available to use. Its supposed to be a 60GB model. So contacted Apple again to check if its OK to send it back with the same Repair ID and checked they aren't gonna charge me.

Will await there answer, could do without this at the moment got enough stuff going on without having to get my iPod fixed :-(
