My roommates iPod is acting up. It keeps skipping songs randomly. I've read that others have had this problem and it was fixed by zeroing all data using disk utility and then reinstalling the software. However, I've also read that this wil make the iPod unusable and that it won't allow you to reinstall the iPod software. It seems some have had no problems though. Has anyone here tried this? The theory is that by zeroing all data it will find bad sectors and disable them. I know it's basically a temp fix and that the HD will fail eventually but he would like to buy some time with this tactic. Any advice/help would be much appreciated.
