    Take a System Information view of the hardware, select the bus that's used for the drive.

    Is the drive listed and if so, is its S.M.A.R.T. status verified?

    A screenshot of your Disk Utility would help.

    Now type

    diskutil cs revert /

    then when terminal is done, type:

    defaults write com.apple.DiskUtility DUDebugMenuEnabled 1

    then close terminal, open Disk Utility,

    then go to menubar, click on "Debug" menu.

    Then select "Show every partition"

    Then you will see your internal drive right at the list, Right click and mount it.

    You should see your partition again.

    If it doesnt work then I don't know.

    Option key boot to Mavericks then run diskutil cs list again and tell us what it says.

    It looks like you ran it while booted to Yosemite the first time?

    That's a peculiar discrepancy, I can't think of anything in Yosemite that might prevent detection of the hard disk drive.

    When you boot Mavericks from the hard disk drive, does System Information show its S.M.A.R.T. status as verified?

    Use Disk Utility to verify (not repair) the volumes of the HDD. Does the utility report that both HFS Plus file systems 'Macintosh HD' and 'HD2' are apparently OK?

    Wonder whether there's a hardware problem.

    What's the model identifier of the iMac?

    What make and model is the drive?

    S.M.A.R.T. status is verified
    i checked, verified by disk utilty, 'Macintosh HD' and 'HD2' are apparently OK.
    how can i know the model identifier of the iMac? (it's late 2012 iMac 21.5")
    drive is seagate (APPLE HDD ST1000LM024 Media)

    Thanks.

    System Information will show the model identifier, the firmware and so on.

    What's the firmware?

    Whilst in Mavericks, please use the Startup Disk of pane of System Preferences to prefer 'SSD' then start Recovery OS (Command-R at startup).

    Does Disk Utility in Yosemite Recovery OS show the hard disk drive?

    If you start Yosemite in safe mode, then is the hard disk drive recognised?

    Yosemite sometimes does odd things and converts other partitions to core storage volumes, and that is what airlied and I were thinking, but that does not seem to be the case here.

    So you can boot from the external and Yosemite works fine, but just can't see the internal. Then you can option key boot to Mavericks on the internal and all is well there. Have I got that right?

    Hmmm... dunno. Obviously the internal is okay. It is odd Yosemite can't even see it in System Report.

    Maybe just something buggy with Yosemite at this point.

    Safe mode no difference, there is no hdd.

    Not necessarily. Capabilities of Disk Utility are limited.

    What's the firmware of the iMac, and the model identifier?

    on yosemite in system information, SATA Intel 7 Series Chipset says "Unknown"
    on mavericks it shows the hdd's information.
    i think the problem is about chipset drivers. if this this was a windows pc then i would try to install the drivers.
    is there something like this in mac, like installing drivers?

    Nope... the OS comes with kext files (drivers) for standard Mac hardware like you have. The fact the chipset is not even ID'd from Yosemite is what makes me think nothing is wrong with the internal drive and this is just a Yosemite bug.

    I would not worry about it until the final Yosemite version comes out.
