My internal hard drive is not recognized by the leopard installer disk

i just got my leopard delivered this morning, and have just put it in, every thing is going well, until it comes to the screen where you select the hard drive you want to install leopard on, and my internal hard drive does not show up, however other drives do (like my external hard drives and usb sticks).
really hope someone can help! thanks

I am having the same problem with my MBP with Leopard. I get a flashing question mark on startup, and have repaired/permissions and my startup disk doesn't show up. I reset PRAM, and then ran permissions again to no avail. If it really is Spotlight just indexing, Apple should tell us that in their technical documents. If anyone has any other solutions, that would be appreciated.

  • My external hard drive is not recognized by my computer.

    My external hard drive is not recognized by my computer. I used it earlier and it was fine however my computer froze and I unplugged my hard drive without properly ejecting it. Now when I plug it in nothing pops up. I've tried on three different computers and no luck. I hope this is fixable! Please help.

    Care to share which OS you are using?
    Repair permissions & restart your computer.
    Zap the PRAM

  • New hard drive is not recognized by my MacBook Pro.

    New hard drive is not recognized by my MacBook Pro. The supplier says I need to update my BIOS. True? How do I do that?
    Hard drive: NN2-72-500-SSE Seagate Momentus 7200.4 (ST9500423AS) 500GB Laptop Hard Drive
    Mac OS: Mac OS X Lion 10.7.5

    I went through a similar issue with a Seagate Momentus 750GB HDD/8GB SSD with my late-2011 MBP.  No matter what I tried, the machine would not recognize the drive.
    To test it, I installed the drive in an old ThinkPad, and it worked fine.  Then I tried installing it in my PS3, and the drive worked fine there, too.  It was only the MBP which had issues.
    I don't *think* Macs have a BIOS to update.  But I know my MBP has issues with certain HDD's (including another external which works fine on other Macs and all Windows machines).
    You might be able to find my thread by searching under my username, perhaps something in there will offer a tip.  Otherwise, you might have to go the same route I did: install a WD Scorpio Black instead.  Or upgrade to an SSD.
    Good luck to you-

    My computer failed and the main drive had to be formatted but all my music was on a separate internal hard drive.

    I had a large part of it backed up on DVD's but it does not want to recognise them either?
    Any tips?

  • Two external hard drive are not appearing on the desktop anymore on my 2008 24" iMac. One is a Lacie d2 Quadra and the other is a G Drive. Both are 1 Tb

    Two external hard drive are not appearing on the desktop anymore on my 2008 24" iMac. One is a Lacie d2 Quadra and the other is a G Drive. Both are 1 Tb

    Are they daisy chained? Have you tried them one at a time? Have you tried a different FireWire cable? Do they show up in either system profiler or Disk Utility? Have you reset the SMC? http://support.apple.com/kb/HT3964

    Otherwise software may be attempted to access the drive. The the computer up in Safe Mode by holding shift when you turn it on. Also be sure to power off and on the hard drive itself.

  • New Internal 1 TB hard drive is not recognized by OSX 10.5 Install

    My iMac G5 iSight was not booting up. I brought it to the apple store and they diagnosed that it needed a new hard drive. Decided to DIY and save $350. Bought a Hitachi SATA 3.5" 1 TB hard drive. Installation was not too difficult. It took several attempts to format, then installed OSX. Now just a gray screen and fan comes on at start up. When I run the utilities program on the install disk the hard drive does not appear in list for formatting or for target drive for OSX installation. However the disk shows up under system profiler SATA drive. I did not see any jumpers on this drive or the drive I removed. I also removed the 1 GB ram extension because I was getting kernal panic when trying to install the OS. Any help/advice would be appreciated.

    The iSight models are NOT user repairable except for RAM installation. You will need to take your computer to an Apple Store or an AASP for the proper HD installation.

  • External Hard Drive suddenly not recognized

    I have a WD 500GB external hard drive that I use to back up my data. I only have one hard drive as I'm currently living abroad and couldn't bring a 2nd with me.
    I plugged in my external last night to back up my MacBook Pro and it backed everything up. I even went into Time Machine to go back and restore a file or two and that worked without problem. I have been using this drive for about a year to back up everything on my Mac and, although sensitive, it seems to work okay.
    I plugged it in this morning and nothing. My Mac will not recognize that the drive is not plugged in in Time Machine or in Finder. If I go to Apple Logo > About This Mac > More Info... > Storage tab, it just shows my internal hard drive and my CD/DVD drive. If I click on Disk Utility with the drive plugged in, it shows my Hard Drive (Macintosh HD) with two icons, one inset below the other and both in black font, and then my external hard drive has two underneath, but only the top one is black font - the one underneath is greyed out.
    It goes like this:
    250.06 GB Hitachi...
         Macintosh HD
    500.08 GB WD My Passport
         Time Machine Backups (greyed out)
    Superdrive (greyed out)
    When I clicked on the 500GB one and told it to repair/verify it said the disk was working fine. I tried unplugging and replugging in the drive (it is not recognized in Finder so I could not properly eject the disk). I restarted my Mac with it unplugged and plugged it in afterward and nothing.
    The HD itself is working, the light is blinking (not solid) and I can feel the hard drive spinning, but I'm at a loss as to what to do to get my Mac to recognize it again.
    Any suggestions would be helpful.
    Thank you!

    I also wanted to add, when I click on the greyed out Time Machine hard drive that's listed and then click "Info", this is what it says:
    Name : Time Machine Backups

  • Hard drive is not recognized

    i just recently have made the pc to mac switch and am now in the process of transfering all of my music and what have you. i didn't get very far due to the external hard drive that i use is not recognized by the mac. ive had friends plug it into their macbooks without a problem, and it still works with the pc. so im wondering if anyone may know the proper diagnosis for such an ailment?

    Ah I see, probably because it's an older version and does not run on a Intel iMac.
    Check out your finder preferences to see if you have hard disk checked to be visible on desktop: Finder>preferences, general tab.
    How do you connect your external drive to your iMac> firewire or USB2?
    For example have you tried a different USB port? Maybe your port or ports not giving as much power as required to operate the device. Is the hard-disk self powered?
    Try a different cable.
    Also what make and model is your external drive, someone might help if there is an issue with particular drives that are not mounting.

  • USB hard drive is not recognized on MBP running Lion

    Hello,
    I have:
    - Freecom ToughDrive Pro USB hard drive
    - New MBP running Lion 10.7.3
    When I plug the disk in an USB port in the MBP, the light that indicates operation starts blinking but very lighltly colored and the disk is not recognized by the computer. I have put data on it using iMac Snow Leopard. I have plugged the disk into a MBP running Snow Leopard and it works. I have also tried another Lion (older MBP) and it also works.
    What is wrong? How come the disk is not mounted or shown in Disk Utility. Can it be a power issue? Any ideas?
    I have noticed there a lot of similar posts in the forum and none has been satisfactorily solved. Is this a mayor Lion bug? If yes, how can I downgrade to Snow Leopard?

    Thanks for the reply.
    However... how is it possible that with all other MBPs I have tried it works just fine? Has Apple lowered the power levels in recent models? The other MBP where I have tried the disk on are just over a year old, my current one is only a month old.
    Are you saying that USB ports on different Apple computers are supplying different levels of power? That's psychotic! It should be a standard power level... or it should go up on newer models... not down!!!
    I think I'm just gonna return this piece of scrape and get my old (one year old) MBP back... Snow Leopard was bliss compared to this... I rather go back than have to jump to a store to buy a cable to make something work that should work by default.
    On the one Mac it does not work on that Mac does not put out enough power to fully power the drive. If it works on other Mac's we know that the drive works, so that question is answered. And it doesn't work on your newest Mac then there can only one answer, Not Enough Power is being put out by the USB port to fully power it.
    Yes the one Mac that it is not working on has a lower USB power output. Why, I have no idea.
    This is Very Common you can find posts about it on all notebook forums. Psychotic, No. Yes Mac is touted as "It Just Works" which is a flat out LIE.
    Do what you think is best for you. Good Luck

  • Internal hard drive does not mount in disk utility

    My internal hard drive no longer mounts in Disk Utility. It is grayed out. I have extraordinarily frequent spinning beach ball/freezes, in Safari or Apple Mail. The most recent symptom: upon rebooting or just starting up, I see flashing black on the display. This has been occuring for more than six months. Of course, I have made total and frequent backup's. I bought new RAM, but have not yet installed it, and I susect this might help. I have done repeted troubleshooting many times each:  Apple's Disk Doctor, Repaired Permissions, Reinstalled the Mac OS, safe boot, Alsoft's Disk Warrior, Apple's longer Harware Test, etc. I have worked as a new user, too. All tests done report that all is well. What od you thnk the problem is? Must I drive 1.5 hrs. each way to the Genius Bar at my nearest Apple Store? Might I try to erase the hard drive as a fix? I hate to do this, only as a last resort, as it is so time-consuming. Should I just update my Mac OS? Please advise, out there, if anyone can offer any advice, I would be greatly appreciative.

    The list of issues you posted probably would not get shorter if you attempt to 'upgrade them' away, as usually that kind of effort is not effective yet may expose more of the same problems while not necessarily revealing the original weakness. Another OS X installed over a set of problems seldom helps.
    How full is the hard disk drive? If it is too full, or has been very busy in use several years, it may be time to replace the HDD and perhaps put a larger capacity one in the computer. And if the main computer hardware checks out OK (tested under a variety of duration and stress tests) then also consider a RAM upgrade if the device is not already at the maximum capacity.
    When was the last time the hard disk drive was devoid of content, maybe wiped -- erased and reformatted by a third party disk utility or have a utility overwrite the entire HDD with zeros? This used to be a common tech service in the course of a major effort to restore a Mac. Or Defragment?
    If you can do the latter, this could help resolve bad sectors and remove old data or corruption on the hard drive. Or get a new HDD and before committing a new OS X install & apps to it (or a re-clone of a complete backup) test the drive and be sure it is ready for use. Not all new drives are perfectly ready; some need to get exercise first.
    I'd bet on a new hard disk drive of larger capacity (also note spin RPM rate and data speeds) and a full RAM upgrade.
    If you have a backup clone on an external hard disk drive (in a boot-capable enclosure) you could really go to town and before you erase the main/only hard drive, make a backup clone and test its ability to boot the Mac. Or put the old drive and content in a suitable boot capable enclosure of the kind with its own power supply, and deal with it later.
    Then consider a later version OS X -- whatever most recent version that model can support... {edited}
    Good luck & happy computing!

  • External hard drive is not recognized in Migration Assistantt

    I had my hard drive replaced on my iMac, Mac OS 10.4.11, Snow Leopard.
    I backup my computer using Time Machine onto an external hard drive.
    In Migration Assistant, the external hard drive does not show up. There are no choices to choose to migrate from.
    Any suggestions please!

  • How do I replace my internal hard drive and not lose windows partition?

    Hello,
    I am wanting to swap my internal hard drive out for a larger one. What do I do about my windows partition? I only use boot camp, and there is some stuff on my windows side I don't want to lose. I know how to make a clone for OSX, and I know how to replace the actual hard drive, it's just the windows that I am a little sketchy on.
    Thanks for your help.

    WinClone - check the faq and forum for tips and read the docs
    http://www.twocanoes.com
    Pull your hard drive and put it in external case, OWC sells such kits, you could probably use a good windows clone program too.
    but you need room on an (external) hard drive to hold the Windows image (uses a sparse disk image file is all).
    Paragon Software has been busy releasing programs and updates to help Mac users running Windows, using NTFS (and EXT2/3), as well as CampTune (free for now) for resizing Windows or linux boot camp partitions.
