Internal Hard Drive Not on Desktop

A second internal HD that was installed new in my machine by my campus reseller--now in use for over a year--has disappeared from the desktop. It does appear in both system profiler and disk utility. It is a Maxtor Basics 500Gb drive. As it has all my project files on it, I would certainly like to retrieve them (I do have some backups but not complete). Best steps to take?
Thanks,
Karen

  • Secondary internal hard drive disappeared from desktop after forced restart

    I have three internal hard drives, one for system, the other two for data storage. While permorming a search on one of the data drives i clicked the "X" to the right of the spinning wheel on the bottom right of the search window to stop the search but the computer froze (wheel kept spinning). I then went through the dock and quit all applications, except for InDesign which wasn't responding to force quit.
    The only way out was a force restart. Upon restart, one of the internal data hard drives did not show up on the desktop, nor after a couple more restarts, nor after restarting from the installation disk, verifying and repairing disks and permissions on the other hard drives with disk utility.
    where did it go?
    G4   Mac OS X (10.4.9)   Dual 1.25 GHz, 2MB L3 cache each, 2GB DDR SDRAM

    no it doesn't show up at all in those either.
    Hmm. Then that sounds like the interface to the drive isn't even talking. You could try opening up the computer and making sure the cables are all connected firmly (of course, it should be off).
    here's the log:
    Nothing here looks too alarming.

    Unfortunately, I don't see anything helpful here. It's just like it disappeared (or never existed) as far as the OS is concerned. If you can find your original disks that came with the computer, you could try running the hardware test and see if it kicks up any errors, either with a drive or a drive controller on the motherboard.

  • IMac G5 Internal Hard Drive Not Recognized

    I shut down my iMac G5 with the power button and not through the typical shutdown procedure once and then when it booted up it would not get past the gray screen. I eventually used the Leopard DVD to try to boot it and was able to get to disk utility to look at the drive. I tried to repair the drive but then the machine froze and I had to restart once more. Now the internal hard drive isn't recognized or seen at all. I actually switched out the SATA hard drive with another spare I had and that was not recognized either. I can get the mac to recognize the installation DVD still so I know my computer still functions properly but I just need it to recognize the drive now. Does anyone have any ideas how to resolve this?

    Have you access to DiskWarrior or TechToolPro? Either of those might fix your problem otherwise, try booting from the Apple Hardware Test on your install disc and see what it says.

  • Internal Hard Drive Not Appearing in Finder

    I just had to do a reboot of my Mac Pro as Final Cut Pro kept locking up and when the computer was back up, one of my Western Digital 2 TB internal hard drives is missing!  When I restart, I got a message saying something like the disc inserted cannot be used.  It had 3 options and the first time I hit eject thinking it was talking about a DVD, then when I rebooted again I hit the details button and it pulled up Disk Utility.  I can see my HD in the menu but when I click on it is says unmounted.  The other 2 TB WD Hard drive is working fine.  Do I need to click on the verify disk or repair disk button?  What should I do? I have quite a bit of video footage on this drive that is missing so I'm super worried I will lose the videos!

      The drive is a goner otherwise though.  Since I was solely using this failed drive recently, I may have just worn it out, which is too bad, even though I worked with an identical 2 TB WD internal drive earlier this year and never had problems with that one. 
    Drives shouldn't just wear out from use, at least not in a reasonable number of years. They are designed for that. Drives however do fail. However, that drive is more likely to be badly corrupted than it is to be mechanically failing. When you are finished grabbing the data off it, use Disk Utility to zero it out. If it can successfully be zeroed out then it is most likely fine to continue to use.

  • Internal hard drives not mounting on startup

    Problem: I recently did a clean install of Mac OS X 10.8 Mountain Lion on my Early 2008 Mac Pro. Since then, one or more of my four internal hard drives will not mount at startup, and it's seemingly random which ones will or won't mount; it differs from one startup to the next. Obviously, the boot drive starts up, but the remaining three drives are hit-or-miss.
    Troubleshooting So Far: I can open Disk Utility and mount the disk(s) manually, and when I click Verify Disk, the hardware checks out okay. After my most recent startup, I brought up the System Log in Terminal (sudo syslog -B) and found this entry for one disk ("Media 1") that did not mount:
    Apr 25 10:40:09 new-host-2.home fseventsd[48] <Critical>: event logs in /Volumes/Media 1/.fseventsd out of sync with volume.  destroying old logs. (454 0 68038)

    There were no entries for the disks that mounted correctly. Can anyone make sense of this for me? The system jargon is a little beyond me.
    Thanks for your help!

    Is "Media 1" the name of the volume, or is it just "Media"?

  • Time Capsule internal hard drive not visible

    I have one of the older 500GB TC. It worked fine for a year then I decided to wipe the hard drive to erase the contents. I stopped the process in the middle of clearing the hard drive because it was going on about 8 hours. Every since then the TC works fine as a wireless router, but the internal hard drive is not visible. It won't do any back ups and it's not visible in the Airport program.
    Any suggestions?

    Hi,
    We won't concern about RPM, faster (more rpm) is better. The HDD's are much, much, much, much cheaper now. They were more expensive during a flood in Thailand few yours back. Yes, you can use WD HDD for your computer. You can pick one from the following list:

  • How do I make an internal hard drive not mount at startup?

    I have an internal hard drive hooked to an ACARD ATA RAID controller that I use for backup purposes, and I would like to mount and unmount it manually. Disk Utility in OS9 and earlier had an option not to mount a disk at startup, but I see no such option in OS X.
    I can manually unmount the drive in Disk Utility, but it always comes back up when I reboot. How can I keep the drive from mounting upon reboot?

    I discovered this in a quick internet search.

  • New internal hard drive not recognized at all!

    Hello everybody!
    I really need your help. I tried to upgrade my internal 120gb drive to a Western Digital wd2500bevs. But when I start my Macbook with the Leopard DVD neither the System Profiler nor the Disk Utilities Program recognize the drive for a possible installation. When I reinstall the old drive everything is back to normal and works perfectly.
    This is what I already tried to fix the problem:
    I took the drive into an external casing => it was recognized immediately
    I then formatted it => no change after installing it into the Macbook again.
    I cloned my system with CCC on the WD and then installed it => no system found.
    I have another disk of this kind but the same problem and another 160gb Toshiba disk which is not recognized as well.
    Please help me! I couldn't find help in German discussions yet so I hope anyone of you guys can help me.

    You say the drive is "recognized" but your original post stated it was not present in Disk Utility. I'm puzzled. Have you attempted to partition and format the drive?
    Extended Hard Drive Preparation
    1. Boot from your OS X Installer Disk. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger.)
    2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
    3. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the number of partitions from the dropdown menu (use 1 partition unless you wish to make more.) Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the volume(s) mount on the Desktop.
    4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
    5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
    6. Click on the Erase button. The format process will take 30 minutes to an hour or more depending upon the drive size.

  • Internal hard drive not showing up in Finder

    Hello. Whenever I use Lightroom and Photoshop, I have been getting the error about my startup disk being low on space. I've read through several threads and instructions on different strategies to take. However, many of them start with being able to click on the internal drive within the Devices section in Finder.
    My internal harddrive does not appear in the Devices section in Finder. I have iDisk and then two gray harddrive icons that have the name of my external drive. Even when my external drive is not connected to the machine, I have these two.
    When I click on them, it just keeps whatever I had clicked on previously. For example, when I click on "Desktop" it shows my desktop and when I click on the mystery gray drive, it keeps desktop.
    I've run disk utility > repair permissions and I get several messages that permissions differ on some things and warnings about SUID files on other things.
    Am I in the right spot to fix my problem? What kind of error should I be looking for and when I find that error, what do I do?
    My thinking is that once I fix this problem, I can move on to my low disk space problem. Finder shows that I have 8.39GB of free space but that goes down to Zero fairly often.
    Thanks in advance for your help.

  • External hard drives not on desktop

    None of my external hard drives are showing up on the desktop.  I can see them in finder and disk utilities so the card is working correctly. Any suggestions?

    Thanks

    Nope, tried already that (default). I got a couple of external HDDs (WD 1 TB, WD 500 GB) loaded with tons of personal data, used to run flawlessly but after Lion seems it won't read them. They do show grayed (not mounted) on the Disk Utility but nothing on the Finder windows. I can read/write and use my data on any other computer, PC, Laptop, Mac Book, etc but not mine. Only diff: I installed Lion.

  • New internal hard drive not seen in disk utility

    Hi
    I replaced my hard drive with a western digital black edition but when I use it as an internal it is not seen by the disk utility. 
    I have installed and booked from the new drive using USB so it doesn't seem faulty. 
    When I use the old drive as an internal it works so I don't know what's going wrong. 
    I have had a look at similar problems but nothing I have tried has helped. 

    It may be the internal connecting cable that is the problem.  If you can install the new HDD in an enclosure, connect it to the MBP, then see if you recognize it using the OSX installation disk.  If so, the internal connector should be replaced.
    Ciao.

  • Mac mini internal hard drive not recognised during internet recovery

    mac mini 2.3GHz OS X Lion
    I turned on my comp and got the folder with the question mark. Went into recovery and am not able to do any of the proceedures. I can see something in the disk utility, but it is not mounted. I was able to recover an old internal drive connected with a SATA wire, but not what I was looking to do. Have had this less than 2 months. I wish apple had better steps to follow for recovery. Just want it to function the way it was bought. Any help is appreciated. First time posting!

    Sounds like either a failed Hard Drive or other Hardware problem.
    Contact Apple or your local AASP and make an appointment to have it looked at.

  • PLEASE HELP!- New internal hard drive not recognizing

    I have a MacBook pro unibody, purchased October 2008, 250 GB, 2.4 GHz, 4 GB RAM. I bought a new hard drove from OWC, which is 750 GB. I followed all I strychnine from their website by installing osx again on the new drive, and transferrin data and updating the programs. when I checked the hard drive to see if the files were all there, they were. but once I installed in in the MacBook, and turned on, a blue screen with a flashing blue folder and a white question mark popped up. what did I do wrong???

    Restart holding down the Option key, the system may not know the new drive is your start-up drive. Select the drive and once OS X is up go to System Preferences-Startup Disk and choose the internal drive.
    If it still doesn't start then you made an error somewhere. The correct process would be to put the new drive in an enclosure and format it first to Mac OS Extended (Journaled), then using using SuperDuper or CCC clone your old drive to the new drive, once that has been done swap the drives and you should be done.

  • Hard drive not on desktop

    My Grandson just got a new 13" Macbook. I was assisting him in doing a Bootable backup. His Hard drive is not mounted in the default area of the desk top. As a matter of fact, it is not mounted anywhere on the desk top. It does show in the finder "as cover flow".
    He claims that is the way it came, which I find hard to believe. I've never had a Mac that the HD wasn't on the desktop.
    Outside of re-installing OSX, I have no idea how to correct this. Has this happened to anyone else out there?

    thanks, all the time I've used a Mac I missed this one item. Never too old to learn . Thanks again.
