Disk Utility Not Recognizing Hard Drive - PLEASE HELP!!

So, I just bought this Power Mac G4 from a friend to run my Digidesign hardware. I turned it on this afternoon to install the Apple software for the wireless mighty mouse. When I turned the computer on, the second hard drive was not present in Finder, and I could not locate it in Disk Utility.
I have two hard drives present in the computer ... the 120gb main hard drive and this 2nd internal 80gb hard drive. I'm not very "tech savvy" with the comptuer outside of running protools ...
Does anyone know what the problem could be? Or is it likely that the hard drive just fried??
Thanks,
Justin

When two hard drives are attached to the same data ribbon cable, connected to the same IDE controller, one drive must be configured as "master," and the other drive configured as "slave." This is accomplished by placing a plastic jumper (sometimes two jumpers) across a specific pair (or pairs) of pins on the back end of the drive. If the manufacturer didn't apply a label to the drive with jumper designations, the user manual or manufacturer's web site will have the info needed for that specific hard drive. The drive connected at the end of the ribbon cable should be configured as master, and the drive connected to the middle connector as slave. If the 80 GB drive isn't mounting, it's probably configured the same as the 120 GB, so check both drives.

  • Blinking folder with question mark, and disk utility doesnt recognise hard drive, please help!!!

    So today i was using my macbook pro and for some reason my CD/DVD drive was causing noise when i put a DVD inside it, and for some reason it did not recognise my DVD. I force ejected it using the restart and clicking, but after that my computer showed a blinking folder and question mark during start up. I restarted my computer to Recovery HD, but instead it took me to internet Recovery HD (i have mountain lion), and so i went to disk utility to repair my disk, but in the left it did not recognise my hard drive. Please help! Im not that experienced in computing!

    Sounds like some sort of power issue and now your drive is not working.
    You'll have to take this to Apple for repair.
    You should read this if you don't have recent backups of your data off the machine.

  • HP dv4t not detecting hard drive, please help!

    Hello, its been just a little over a year since I've bought my HP dvt, and of course the problems start as soon as my warranty has ended.. It's been working fairly fine most of the year, and then just all of a sudden while not even doing anything of importance on computer last week I got a blue screen error..
    Ever since then I have had so much problems. At first it just started out with closing the screen and reopening it crashed the laptop in a couple minutes..
    The main problem now is, it just does not detect the hard drive when booting up! Sometimes (rarely) it does though.. I thought it was a windows problem, so I did fresh clean install of Windows 7 and reformatted the hard drive. Then I ran CHKDSK and it did it stuff and said volume clean at the end.. It worked perfectly for a couple of hours, was able to close screen and open with no problems. I downloaded "Hard drive sentinel" to monitor my hdd health, and it said 90% which is apparently excellent. Yet as I was installing adobe reader, it crashed, got the blue screen of death and has not been able to boot up since
    Can anyone tell what is the problem with it? Anyone else have similar problem? I've tried to reformat again with CD but it doesnt even recognize any drive to install on..
    Important thing to note is that, in the BIOS screen when i run the HARD DISK TEST, it does recognize it! So i dont understand why it doesn't load the operating system or cant see the hard drive anywhere else!!
    What is at fault even? Is the motherboard dead? Althought the bios screen loads fine so does that mean its OK? Is it the hard drive? CHKDSK and the hdd health monitor thing said it was ok right before the crashes..
    Please help, I have my first computer science lab in like 2 days with my laptop breaking just a couple days before it with barely any money left to buy a new laptop

    Time to replace your Hard Drive. BACK UP NOW!!!
    This will be the 3rd HD in a new HP HDX 18 for me (6 months old).
    Open up the HD bay and take a look at the model of the HD.
    If it is a SEAGATE MOMENTUS 7200.4  they are known to fail in as little as 1 month from install, and do not last more than 6 months.
    Google the brand and you will see that most people are reccomending that you remove the SEAGATE product ASAP (data recovery is next to impossible) and replace it with something else.
    I had just finished setting up the PC as I wanted it, OS, programs / Bios, software upgrades, then without warning the 2nd HD went.
    I lost EVERYTHING in my C drive, was just preparing to do a full BU and Mirror Image after deleting both from my D and External Drive.
    HP is replacing one piece of crap with another, I will be shopping for a different brand for the C drive after the laptop comes back from repair.
    There seems to be no end to this BS with SEAGATE drives.
    DO A FULL BU NOW!!!

  • 'No' symbol on start-up, disk utility not recognizing internal drive

    Need a little assistance.
    Two days ago I was using the Macbook and it froze. Restarted and I was hit with the international no symbol. I've also gotten the blinking file folder at times when I've tried the holding down of various buttons on start-up.
    I put a Hitachi 750 gb harddrive in last fall, it has been working fine up until now.
    I do not have the system disk for Snow Leopard on hand, so until I can get it from my Dad, I decided to check on the system disk I actually have from the laptop purchase in 2007.
    This allowed me to get to the start-up disk and disk utility area. I could not find my external harddrive in the list for a start-up, and it is the back-up using Time Machine. I also could not get the internal harddrive to be found in the utility so I could do a repair. It did seem to recognize that there is a drive, but not the actual named portion of it that contains the info.
    I removed the internal and put it in an external case: my netbook recognizes that there is hardware, but does not let me access it. I attribute this to the fact that the drive is formatted for Mac and the Windows machine can't recognize the data.
    My next step was to see if my old iMac would recognize the internal as an external, but since I don't know where the keyboard is and it is running an early version of OS X, figured it won't do me much good.
    What is my next step? Will the Snow Leopard disk make a difference? Or is the reaction with the older system disk going to carry on the same way with Snow Leopard?
    I was going to buy a Macbook Pro, but not for over another month, so I'm hoping I can figure something out with this and make it last a little longer.

    I hooked my internal as an external up to my Mom's Macbook Pro and it recognized my HD. I'm thinking it is something internal with the hook-up, which is awesome, because maybe I can actually fix it!!!!  Any thoughts?

  • Disk Utility not finding Hard Drives after Updates

    Howdy;
    Updated my B&W G3 to 10.4.4 and itunes 6.0.2. After update and restart, ran Disk Utility (DU), which seem to just get into a loop "Gathering disk data". Force quit DU and tried running from Tiger DVD, but similar story.
    I have done a little research and there has been many problems with DU linked to itunes 6.0.2 update, but not quite the same (no B&W G3 w/10.4.4 and different DU hang point).
    I followed: http://discussions.apple.com/message.jspa?messageID=1505537#1505537
    and even tried moving iTunes to desktop; trashing several iTunes.pkg files; restarting, all to no avail.
    Any additional suggestions out there?

    I doubt that any jumpers are needed, since this is the only (master) drive in the system. WD's site has pretty good info on this. Verify for yourself however.
    Also, from their site:
    How to partition and format an internal slave drive or an external drive in a Mac OS X (all versions).
    Answer
    In Mac OS X, you can use the built in Disk Utility to partition and initialize the drive so it will appear on the desktop.
    1. Open the main drive (the drive that contains the operating system).
    2. Open the Applications folder.
    3. Open the Utilities folder.
    4. Select Disk Utility.
    5. The drives are displayed on the left side of the window. Click on the drive that you wish to partition (the top drive listing for the hard drive that you want to work with).
    6. Once the drive is selected click on Partition.
    7. Click on the Options button to select the partitioning scheme.
    8. Click on Apple Partitioning Scheme or Apple Partitioning Map and then click on the OK button.
    9. You will see several options for setting up the drive. Once you have selected the number of partitions, the format type you want, and a volume label, click the Partition button.
    10. Following the completion of this process, the drive will appear on the desktop.

  • Using Disk Utility to erase Hard Drive

    Hi All
    I just bought a new external hard drive and am using Disk Utility to erase and format it. I did not know for sure if erasing the hard drive was the right thing to do. Anyway I set up the Volume as follows from the mac help instructions:
    1.format OS extended journaled
    2.Install OS9 disk driver.
    3.("Zero all data" and "8 Way Random Write Format"). So it has been running for about 3 hours now and is only 1/8 of the way writing 0's to disk.
    My question is should I continue on and just let it finish up? At the rate it is going It might be done by sometime tomorrow.
    Or can I stop the erasing process without hurting the hard drive.
    Then start disk utility erasing the hard drive without this Zero all data.
    Thanks much

    Just to confirm your impression, S. Frigolett: yes, everything should be fine now.
    Zeroing a drive is advisable if you have reason to believe there may be bad data storage blocks on it; zeroing identifies those blocks and prevents them from being used (because using them would result in lost or corrupt data). A simple erase doesn't do that, but on a new drive straight from the factory there is no reason to think it's necessary.
    The 8 way random write option is for people who have extremely sensitive data to erase from a drive that may pass into other hands, and who want to be sure that no one short of the NSA will have any chance of recovering any of that data. A new, empty drive has nothing on it that even the NSA could recover, so there's no reason to erase it that thoroughly.

  • I have macbook pro 13" I want to know how to copy files from my mac to the external Toshiba Hard Drive. I can't even delete files from my external hard drive. please help me my macbook HD is almost full and I have to copy my images to the Toshiba HD

    I have macbook pro 13" I want to know how to copy files from my mac to the external Toshiba Hard Drive. I can't even delete files from my external hard drive. please help me my macbook HD is almost full and I have to copy my images to the Toshiba HD

    To delete files from your external HDD, attach it to your MBP and drag the unwanted files to trash and then empty trash.
    Then you select the files that you want to transfer by 'drag and drop' to the external HDD and trash the files on your MBP.

  • HELP! - Start up disks does not recognize hard drive!

    I tried reinstalling Tiger and my start up disk cannot see a hard drive. Would a new hard drive be a good solution?

    Hi Scoobie,
    You might want to start a new thread about this, but basically I would say that:
    - If you aren't sure what to buy, the easiest solution is probably to go to an Apple store or another Apple Authorized repair shop.
    - If you're feeling more confident about replacing it yourself, you basically need to know:
    1. What type of interface (e.g. SATA on new Mac desktops, I believe ATA on laptops and older Macs) your hard drive uses. You can find this, as you suggested, in System Profiler.
    2. What size hard drive your computer uses. Basically this is just 3.5" for desktops and 2.5" for laptops, although I think Mac minis use 2.5" hard drives.
    3. What speed you want. This might not really matter to you.
    4. How much capacity you want.
    I think that Pricewatch is an excellent place to compare prices of hard drives, but if you want to make sure you get a reliable drive and/or don't want to have to do quite so much hunting and comparing, Newegg might be the best place to go.
    Good luck,
    Greg

  • Tiger install not recognizing hard drive

    G3 desktop/400MHz/512 MB RAM/20 GB Western Digital EIDE HD/ OS X 10.4 retail install DVD.
    My friend gave me the aforementioned Mac, minus the HD which he kept, but with the 10.4 install disk. The computer was working fine before.
    I had a blank NTFS-formatted HD to use in it, and from reading Mac forums I knew the Mac wouldn't recognize it, so I used a PC to format it in FAT32 before the install.
    Install Steps:
    1. Booted, holding down the C key.
    2. Selected English as the language, but didn't click Continue.
    3. Went straight to Disk Utility, and the only drive it shows is the DVD drive
    and the DVD itself. System Profiler shows everything but the HD.
    While installing the OS I reached the "Select a Destination Volume" step, and the HD is not listed. The "Options" button is greyed out as well.
    I went to the Terminal option and typed in "df -k" as a friend suggested, then went back to the "Select a Destination Volume" step, but the drive is still not listed.
    Thinking it could be the drive (which was Windows-formatted and found zero errors on) I popped in another drive, with the same results. I also replaced the IDE cable, to no avail.
    All cables are seated properly and the HD is receiving power.
    This is my first Mac since 8.1 and I had planned on using this one to refamiliarize myself with the platform before buying a high-end model, so I'm pretty much flying blind here.
    Any ideas on how to get the HD recognized?

    Okay, a bunch of things.

    If the drive isn't being seen at all then that's something fundamental since even a Windows drive should be seen in Disk Utility. Are the jumpers set correctly on the drive? You might need to take this particular question over to the hardware forum.

  • Disk Utility and 320GB hard drive

    I just installed a WD Scorpio 320GB hard drive in my first-generation MacBook. Everything works fine in normal use.
    When I go to Disk Utility, however -- using the new internal HD as my startup disk -- the "Repair Disk" button is grayed out. The other three buttons are ok. "Verify Disk" shows no errors, and I can successfully run "Repair Disk" when I start up from a Leopard DVD. The "S.M.A.R.T." status check for the disk is OK.
    My question: Is the grayed out button a matter of Disk Utility not being designed (yet) for 320GB disks on a MacBook? -- and I shouldn't worry? Or is the grayed out button a sign that something is wrong that I should be alert to?

    You cannot repair the drive that booted the computer so assuming you didn't boot your computer with the installation DVD, this is normal.

  • Disk Utility - Erasing a hard drive using MS-DOS (FAT)

    Hi all,
    I have recently purchased a 500GB external hard drive. I have used Disk Utility to format the drive from NTFS to MS-DOS (FAT) so I can use it with Windows PC's as well as Mac's.
    My issue is this.
    I copied a 1.16GB file over Firewire 800 to test the speed and then deleted it. After deleting the file the info pane still reports that 1.17GB of the drive has been used.
    Why is this?
    Thanks!
    David

    Did you remember to empty the trash can? If not, the file is in the hidden directory .Trashes on the Windows drive. You don't reclaim the space until you empty the trash.

  • Ipod is not recognizing my passcode, please help!

    I am completly worried because I don't want to erase my ipod and I need it for tomorrow. Is this a glitch? I downloaded the new ipod update software last week, and maybe that did something. I am also not willing to spend money getting it undone, because I know this is not my doing. Please help.

  • Need to run Disk Utility from OSX Disk to fix my hard drive.. help!

    I have a newish early 2010 Macbook Pro. The standard 10.6 DVD will NOT boot my computer and yet I need to boot to DVD to use Disk Utility..
    I'm nowhere near my restore disk so using that is not an option. Is there anything I can do to boot to "single user" mode and run Disk Utility so it can repair my HD?
    Thanks,
    Ricardo

    Without your discs you're really out of luck. The 10.6 SL DVD contains too early a version to boot your computer. You would need a retail disc with a version of SL later than the one that came installed on it. If it came with 10.6.3 or earlier then the latest retail copies of SL should be 10.6.4 and would boot the computer.
    Meanwhile if the computer is functional download and install AppleJack - CNet Downloads or MacUpdate. Read the documentation then run the utility.
    If your computer is not functional then you can try this:
    Boot into single-user mode. After startup is completed you will be in command line mode and should see a prompt with a cursor positioned after it. At the prompt enter the following then press RETURN:
    /sbin/fsck -fy
    If you receive a message that says "*** FILE SYSTEM WAS MODIFIED ***" then re-run the command until you receive a message that says "** The volume (nameofvolume) appears to be OK." If you re-run the command more than seven times and do not get the OK message, then the drive cannot be repaired this way.
    If you were successful then enter:
    reboot
    and press RETURN to restart the computer.
