#188 Trouble with MB Pro late 09 + 750 GB Seagate Momentus 7200.5


I was running rEFIt on a MacBook Pro (late 2009, 13", 2,53 GHz) with a WD Scorpio Blue 500 GB HD and OSX 10.5(.8), Windows XP and Ubuntu 10.10...
and everything was working fine!

Then I replaced the HD with a Seagate Momentus 7200.5 750 GB 7200 rpm HD (ST9750420AS; NOT a Momentus XT SSD hybrid)... and the trouble began:
Each time I install rEFIt, my MacBook freaks out... with different symptoms: Sometimes usbmuxd constantly respawns, WindowServer crashes,
and/or mDNSresponder hangs... sometimes the system doesn't boot but hangs at the spinning wheel. And every 2 or 3 boots, HD utility reports a
corrupted disk... similar to Bug ID 3143295.
Over the last weeks, I tracked the error down: Installed 10.6, 10.6.3, 10.6.4, 10.6.5; everything works perfectly fine until I install rEFIt.... see above.

It looks like rEFIt has some trouble with the 4k-instead-of-512b-Sector stuff of newer/larger hard drives: See also 3016982, 3039932 and 3143295!

    I have the same Seagate Momentus 7200rpm 750GB hard drive, and rEFIt 0.14 is giving me a headache.

    First I installed Mac OS X, updated all the way to 10.6.6.
    Then used Boot Camp Assistant to make it a 700gb Mac / 50gb Windows 7 split.
    Win7 fully installed and updated, so I reboot back into Mac OS.

    Then when I installed rEFIt, the menu does not show up at all after a ton of reboots. In fact, many times the boot just stalls with the Apple logo and the wheel is constantly spinning. I left it there for about 30 minutes to see if it would stop spinning but it kept going, so after that I would just power it off and back on.

    On a few occasions that helped it boot back into Mac OS. I got tired of rEFIt not working with this new drive (it worked so well on the old stock 250gb), so I decided to remove it by deleting the EFI folder as well as the one folder related to it from the Library.

    Now it just spins the wheel constantly and does not boot into Mac OS at all!
    I can hold down the Option key during startup, which will let me boot into Windows 7 if i choose it, but even if I pick Mac it still does not boot, only spins the wheel.

    I tried to start it up from the Mac OS Install CD and choose the Mac partition from the Utilities > Startup Disk, but even that does not work.

    I am lost at what to do, other than the obvious is to reformat the drive completely and reinstall again, as I don't know if rEFIt left any residues on the hidden EFI partition.

  • Hi,

    I'm experiencing similar issues with my new ST9750420AS. If I uninstall
    rEFIt completely, OSX will boot just fine. If installed it the rEFIt menu
    won't appear unless I manually run enable-always.sh after every boot.
    Moreover, installing rEFIt will also cause OSX to run fsck at every boot,
    reporting (and correcting) errors as in bug 3143295.

    A few more points to help underpinning the causes of this issue:
    - I'm sure the disk is not failing
    - there is no mis-alignment between MBR and GPT
    - OSX is *not* installed anywhere near the beginning of the drive (see my
    'diskutil list' below)
    - rEFIt will work just fine if I manually install it in the EFI partition,
    and no fsck will happen on OSX boot
