Q: How long should I let Safe Mode startup run? I keep getting the "disk0s2 i/o error" message and I'm just not sure when to give up and try a different method. I already ran disk utility in Recovery Mode and it said there were no repairs needed.

How long should I let Safe Mode startup run? I keep getting the "disk0s2 i/o error" message and I'm just not sure when to give up and try a different method. I already ran disk utility in Recovery Mode and it said there were no repairs needed but it still kept getting stuck on the apple loading screen.

MacBook, OS X Yosemite (10.10.3)

    I would recommend trying to repair the disk from single user mode Resolve startup issues and perform disk maintenance with Disk Utility and fsck - Apple Support

    Usually that error message is due to a failing hard drive.

    so just give up on Safe mode and hard power it down and then restart using those options?

    You have limited opportunity to attempt to create a backup of your created files.

    That is what the SafeBoot or safemode appears to allow you -- at the moment.

     

    Since the hard disk drive exhibits signs of failure or other major issues, plan

    on a replacement in the near future. You may be able to get the computer to

    start up in a regular full OS X (not safe mode) but consider its hours are limited.

     

    An externally enclosed hard disk drive (with own power supply, not relying on

    Mac ports to run it) is a good basic means of which to use a disk utility to make

    a copy or a Clone of the current OS X. This may help retrieve an archive that

    could be used along with a Time Machine backup, to restore your Mac once you

    get a new hard drive installed inside.

     

    Good luck & happy computing!
