Very important: If you are repairing, then REPEAT the Repair process more than once, to make sure it fixed everything. If it gets to that stage, a Utilities window will open–see if it allows you to run disk utilities on the damaged OS X partition.4. Brannigan 2014 Catherine H. It's not that I'm concerned about zeroing out the data.

Unfortunately if you're running OS X 10.6.8 or earlier, there is no Recovery Drive…OS X must be installed from an external DVD. more stack exchange communities company blog Stack Exchange Inbox Reputation and Badges sign up log in tour help Tour Start here for a quick overview of the site Help Center Detailed Last edited by johnc27; 09-25-2014 at 12:58 PM.

But as it's my startup disk I couldn't repair it, so I tried safe mode.

The laptop is a Macbook Pro (bought it summer '09) and one more detail that may or may not be important: When I tried to boot in safe mode, as I Both come on bootable DVDs, so you'd boot from the DVD, then run the program on your internal drive.

Rebooted and the first time it did boot successfully but then locked up. Zeroing out the disk may appear to fix the issues for a while, but I can guarantee that the issues are still there and will only get worse. Good luck!! Unlike Disk Utility, which can only verify the current startup disk, fsck will verify and repair the current startup disk.

I had the same thing occur with an iMac. Starting in single user mode and trying fsck -fy returned: ** /dev/rdisk0s2 ** Root file system Executing fsck_hfs (version diskdev_cmds-540.1~44). ** Checking Journaled HFS Plus volume. First of all, Disk Utility cannot repair Macintosh HD, and trying to make a back up to an external results in something like "cannot copy, I/O error." Furthermore, I cannot use The built-in FSCK routine is basic…certainly not the be-all and end-all of disk repair.

Tried the Apple Hardware Test, twice, because it didn't seem right. Disk Utility can verify your computer's startup disk (volume) without starting up from another volume. What I did do was load Data Rescue from CD and used the clone function to clone the broken HD to a FireWire external - for some reason it could see darryl Says: January 13th, 2014 at 7:39 pm The next step is a third party disk repair program like Disk Warrior or TechTool Pro.

Using single-user mode, as that's as far as I'm aware the only way I can get any access to the system, I've been running fsck_hfs. Let me know if that resolves the issue! In that case you'd have to safe boot so you can boot up, then disable any third party software normally loads at startup. We Make Computers Work.

If so, then the disk is dying, replace the hard drive, and hope your backups are recent. Not a software issue. Either way: Thank you very much!!! The single user mode screen As the Mac boots in this mode, the screen reports each step of the process.

Good Term For "Mild" Error (Software) Sum of neighbours Exploded Suffixes Why is absolute zero unattainable? Both are much more comprehensive than the basic repair procedures built into OS X itself. Everything seems to work fine till your system hangs briefly and in an unpredictable way. Any feedback would be appreciated, thanks.Click to expand...

Keep holding down the Shift key until you see a status bar appear on screen below the gray apple and spinning gear. But how and why? When it doesn't, that the time to go third party. I had to run it twice as it will only do 3 passes by default (after the first set of passes, it said it couldn't fix the disk, but a subsequent

Lee Says: May 30th, 2013 at 6:11 pm Hi Darryl I've tried /sbin/fsck -fy. However, I'm still unable to start OS X. If that fails, there may be no choice but to reinstall OS X. I wasn't given a disk when I purchased the laptop in 2010.

No peripherals (external hard drive, USB mouse, etc.) were attached so that was immediately ruled out.
