This keeps happening.I've also tried to 'verfify disk' on both external and enternal drives and all is coming back fine.Is there anything else i can do to retrive the contents of my macbook? The information on there is extremely important to me and i'm gutted and worn out at this point. I'm tempted to bring it for a repair at my local mac shop but worried it will cost a fortune. Also it mite be worth mentioning that a few weeks ago i got a message saying 'start-up disk almost full' so i began clearing about 20 gig from my HD. Didn't recieve that message again. At the current time there is 6 gig free. Also the day before this problem began, the music making software i use gave a warning saying something along the lines of 'Cannot reload from save undo history'. This program crashes on me quite frequently but always returns to where it was when it crashed after i reopen the project, but it was now saying it could no longer do that. Alarm bells were obvio

Clean the disc, enable any error-correction on your image conversion software, and give it a go again. share|improve this answer answered Sep 4 '09 at 17:10 caliban 17.1k43857 add a comment| up vote 0 down vote This could be a problem with the drive, or (more likely) a problem with the DVD. Perhaps there's a scratch on it, or maybe just a smudge. It's tough to say. If you copy the files directly, you can still play it with VLC. Also Disk Utility is not your only choice for backing up DVDs. I will point to MactheRipper or Handbrake for other options. share|improve this answer answered Sep 4 '09 at 17:11 jweede 5,12522532 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up using Facebook Sign up using Email and Password Post as a guest Name Email Post as a guest Name Email discard By posting your answer, you agree to the privacy policy and terms of service.

Its sole HDD is a 750GB drive, formatted with Bootcamp. It's still running reasonably well, but in running a defragment pass on it, I've identified that there are a bunch of files which are refusing to be moved by the defragmenter input output error (iDefrag). iDefrag reports a POSIX error code of 5 when accessing the files. Picking one at random and trying to copy the file to another location in the shell also reports an error, which makes me think the problem is real and with the disk / FS. Output of cp is: cp: unity_nophysx.nexe: Input/output error Error code 5 is 'access denied' as far as I'm aware, but the defrag process is running as administrator and running cp using sudo on the suspect file makes no difference. Disk Utility, fsck and the Apple Hardware Test all claim the disk is fine. No SMART errors reported, and while there were some permissions errors, they weren't with the files iDefrag is complaining about, and Disk Utility claims to have fixed them without complaint. There are maybe a hundred or more corrupted files, but still a very small fraction of the drive. As far as I can tell, no system files or crucial data are affected. While it would be nice to retrieve the data, I don't mind reinstalling or going to backups. At this point I don't know if it's really the drive dying, just some bad sectors due to the drive being moved while writing, or some other minor corruption that can be w
