chrisgil Posted August 26, 2011 Share Posted August 26, 2011 Mac pro 8 core - osx 10.6.something (the latest snow leapord) SSD drive. 16gb ram. recently loaded pro tools onto it to edit a project im doing. the other day i went to turn the computer on and it shut down when it got to the grey screen. after days of trying a couple of different things. the furthest I can get is holding down the power button, holding down the eject button and inserting the latest firmware on a disk. it has a progress bar pop up twice then the loading sign comes up, then as the disk sounds like its about to load it shuts down. Also tried the OSX disk to get to disk utility. it says unable to repair disk in red, and that I need to back up everything. Any help to get my system up and running, if only for a couple of days would be great. I need to do some work before wednesday when Im back in the studio. theres also work Ive done which I really dont want to lose. I dont have time machine setup (YET) Quote Link to comment Share on other sites More sharing options...
triplets Posted August 26, 2011 Share Posted August 26, 2011 Turn the computer on while holding down Command-S. This brings you into UNIX. Follow the command line text at the bottom to do a fsck (file system check) and type it exactly like it says on the screen. If that doesn't work, maybe the SSD drive is corrupted and you might have to reinstall OSX, which means wiping the drive. If you don't have a backup of that drive that would really suck.

chrisgil Posted August 26, 2011 Author Share Posted August 26, 2011 ok, a lot of text has come up, so dont want to do anything to f*%@ anything up. at the bottom it says. if you want to make modifications to files: /sbin/fsck -fy /sbin/mount -uw / if you wish to boot system: exit then theres some other stuff, start channel a couple of times, failed to perform channel hard reset a few times Adapter vbus initialised Quote Link to comment Share on other sites More sharing options...
treeboxterry Posted August 26, 2011 Share Posted August 26, 2011 As an experienced user from way back... I've learned that when these things happen - make sure you unplug every other device when you try to start up. Especially firewire or USB hard drives, memory sticks... Times like this... a Disk Warrior utility disk can come in handy... Quote Link to comment Share on other sites More sharing options...
chrisgil Posted August 26, 2011 Author Share Posted August 26, 2011 nothing else is plugged in at all. just waiting for instructions on what to do next, currently in UNIX Quote Link to comment Share on other sites More sharing options...
triplets Posted August 26, 2011 Share Posted August 26, 2011 Type in the one with fsck and press return: /sbin/fsck -fy Quote Link to comment Share on other sites More sharing options...

chrisgil Posted August 26, 2011 Author Share Posted August 26, 2011 shall I exit this then? Quote Link to comment Share on other sites More sharing options...
triplets Posted August 26, 2011 Share Posted August 26, 2011 Type the same thing and try it again. Sometimes it needs a couple of tries. If it says the same, then the drive is corrupted. If you had DiskWarrior you could try that to save the corrupted disk. Quote Link to comment Share on other sites More sharing options...
chrisgil Posted August 26, 2011 Author Share Posted August 26, 2011 same again can I still boot from disk?? Quote Link to comment Share on other sites More sharing options...
triplets Posted August 26, 2011 Share Posted August 26, 2011 Every time you boot and see the white apple on grey background, UNIX is doing that fsck procedure to verify that the disk is ok. If it doesn't get past that, you have a problem with the disk. Any particular reason you put an SSD drive on a mac pro as a system drive?

triplets Posted August 26, 2011 Share Posted August 26, 2011 SSDs are very new. They're still expensive and not really proven yet for music production. To get out of UNIX type exit and press return. Hopefully it will boot in your circumstance. Quote Link to comment Share on other sites More sharing options...
