While it would be nice to retrieve the data, I don't mind reinstalling or going to backups. As far as I can tell, no system files or crucial data are affected. There are maybe a hundred or more corrupted files, but still a very small fraction of the drive. 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. Output of cp is:Ĭp: unity_nophysx.nexe: Input/output errorĮrror 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.ĭisk Utility, fsck and the Apple Hardware Test all claim the disk is fine. 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. IDefrag reports a POSIX error code of 5 when accessing the files.
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 (iDefrag). Its sole HDD is a 750GB drive, formatted with Bootcamp.
I have a late 2011 Macbook Pro, running Mavericks 10.9.2.
