Using Disk Utility, First Aid, Verify Disk, the volume "Macintosh HD" appears to be OK. Is there a way to view any more detail than the console will provide? So that I can learn more about the error. It could be due to low power on the source drive - I am using a 2.5" HDD External enclosure (Mini G2 from Silicon P/L) requires 5VDC/0.5A usb to USB and power (host usb 1 - enclosure usb and enclosure round power split end cable) lead and I am using my MacBook Pro Retina, 13-inch, Late 2012 as the host USB port. The HD inside the enclosure is from an early model G4 Powerbook that was running Tiger OS X. Other answers to input/output error suggest using DiskWarrior so I tried that, DiskWarrior fixed a bunch of flags and repaired permissions but when I ran disk utility again after that to create a new image it failed again for the same reason: input/output error.

Its sole HDD is a 750GB drive, formatted with http://apple.stackexchange.com/questions/129030/how-to-identify-and-fix-files-with-corrupted-inaccessible-disk-blocks 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 (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.

When I open the External drive in Finder, It shows it's empty. When I use the option to "Get Info", I get the dialog box stating it has about 300GB Free. I tried to access External Drive using Terminal, but I had no luck. Checking in Disk Utility, It showed input output error that I have many number of files but ZERO folders. I tried to "repair disk", in the process the external Drive got unmounted in the process. I checked this drive on Windows. I was able to open almost all the folders but I wasn't able to copy anything onto the external drive. One folder caused my windows computer to freeze. Then I connected the drive back onto my MacBook Pro and tried to access the drive through terminal (this time it worked!) and then I tried to delete a folder with rm command, I got an "input/output error". I tried to enter in to the folder with "cd" command but my terminal got frozen. What should i do to recover the files in that folder? What can I do to fix my External Hard disk ? terminal finder hard-drive external-disk share|improve this question asked Oct 1 '14 at 4:45 Jash Jacob 2,76541939 add a comment| 1 Answer 1 active oldest votes up vote 3 down vote accepted If Windows is having trouble opening various folders and is causing your drive to freeze, it suggests that the file system is corrupted or that the disk itself is failing.
