i just wanted to "factory reset "to sell and then after looking in more detail at the specs decided I would do a fresh install of the ox.
I used disk utilty and chose erase free space no the internal hard drive ( 2tb) it took hours and It didnt look like it had worked at the time then when i switched on it would not load so i rebooted to disk utility .
i want to reinstall the Ox but the only startup disk I was given was recovery HD ' LOCKED " and no 2tb internal hard drive.
i checked through about this mac and it is reading the hard drive.
I then booted the computer from usb external and is working fine but i still cannot do anythinhg through disk utilty to get the imac toview the internal hard drive , i have just connected to a macbook pro running 10.8.3 through thunderbolt and now ( first time i have done this ) is showing me a grey screen with a thundrbolt sign
yes it does so i will remove hard drive and try again
how do i investigate the hard drive on the macbook pro im connected to i dont see in finder?
no sorry its just driving me crazy and i was writing fast.
the iMac 27 inch is the one that i erased the drive.
i have now connected through thunderbolt in target disk mode to the mpb and through disk utility i can see it as Macintosh HD ( SUBFOLDER) but not the actual hard drive folder .
it once again gives me 2 options verify disk & repair. i verified , then it came up with the error this drive needs to be repaired.
ok so i started repair and now my MBP has frozen it seems
I dont know if this helps but i migrated my user from this imac 27 inch to the 2013 21 inch imac , will there be a backup of my recvery hd in there?
i see what you mean now though i booted my MBP and pressed option and there was the 2 options macintosh hd (mbp ) and recovery hd ( mbp)
it will take me to the screen giving me only macintosh hd as option , i click and it brings up my old login screen ( i have just realised you can not see the screenshots i sent
it gives me 2 users
1 . my user that i always used with this imac and
2 . another user with no name that says update needed .
if i go to enter and then add my password XXXXX ends up grey screen and no entry sign
10.8.4 mountain lion
im here at os x utilities
if i can restore and start from fresh but if not and i can restore from time machine backup and get the hard drive working again ok
but i cant make any changes to the disk as the options are greyed out , this was my original question.
i know how to get to this os x utilities but i cannot install as i cannot change the partition
this screen i know how to get to ,
i then connect to wifi network and go to re install mountain lion ,
i agree and the computer checks for eligibility then it comes to the screen...
where it asks where you would like to install mountain lion.
there is only one option ' Recovery HD" But is greyed out and when i click it says this disk is locked.
i go back to disk utilty and click on Macintosh hD - Go to partition where everything is greyed out except verify and repair disk . it does state that this partition contains a locked disk and cannot be resized till its unlocked.
does this have anything to do with filevault and encryption keys?
I SUDDENLY CANNOT ACCESS THIS SITE , ACCESS DENIED THROUGH MY WIRELESS CONNECTION , SO I HAD TO LOGIN TO ANOTHER SERVER , WHY IS THIS.
The original problem was that the physical hard drive is not showing up above the macintosh HD , this is why i am facing the problem.
I want to know how to unlock this so i can see the physical hard drive and mount it .
its a bit strange that suddenly i cant access your site
nothing above Macintosh HD ( THE ONLY TIME I COULD SEE THE HARD DRIVE WAS THROUGH ABOUT THIS MAC)
On the left there is
Superdrive ( Greyed Out)
subfolder Mac OS X Base System
When you select Macintosh HD, can you tell me what information it gives at the bottom of the window (Name, Type, Capacity, used, etc.....)?
Also, please go up to the "Utilities" menu at the very top of the screen and choose Terminal.
diskutil CoreStorage list
and press enter
then tell me what it says.
name: Macintosh HD
TYPE: Logical volume group
Disk status: Online
then to the right side
capacity : 2tb ( 19xxxxxxxx) bytes
available: 2tb ( 1999xxxxx) bytes
used: 31.8 mb.
i think the problem is i need to unlock the gard drive but cant find where to do this
No, it's not a matter of unlocking. Locking does not remove the physical drive listing from Disk Utility. There is no mechanism for this. You have a problem with the drive, corruption of some sort with CoreStorage is likely if it is software related.
Please go up to the "Utilities" menu at the very top of the screen and choose Terminal.
then tell me what it says, specifically any info related to a Logical Volume Group for the name Macintosh HD.
You should get a screen similar to this:
John You are a star i got everything working perfect after the cores services terminal command.
