Satellite A60 will not mount drive UJDA760

My Satellite A60's DVD/CD-ROM drive stopped working properly. It no longer could read DVD-ROMs, a serious problem because the recovery disk is a DVD-ROM.
Recently I bought a replacement drive, same model number as the old drive. But when I installed it, the computer didn't recognize the drive. The drive has power and spins disks. The computer just doesn't know it is there.
Anyone have any idea of what can be done to encourage the computer to see the drive? I have updated the BIOS to the latest version but that didn't help.
I appreciate any suggestions.

Hi Phil Prime,
Is the old drive recognized in BIOS properly?
Im not sure but certain drives have a jumper on the backside where the connector is. There you can change between Master, Slave and Cable Select. Please set the jumper to Master and if its not working, try Slave mode.
In worst case the new drive is faulty and you should send it back to shop and ask for a replacement.

  • External Hard drive will not mount on desktop

    I have a 17" Powerbook G4 that has replaced a broken iBook G4. I've been using a Western Digital MyBook Pro Edition as a secondary drive for my multimedia as well as my iTunes Library. It worked fine on the old iBook.
    When I plug it into the Powerbook, using either USB2 or Firewire 800, it will not mount to the desktop. It DOES however appear in the System Profiler as "External HD Button and Lights". The drive is formatted for FAT32 and works fine on my Windows XP desktop machine, so I know the drive functions mechanically. A different hard drive, a Maxtor mounts to the desktop fine using USB2, so it isn't a bus issue.
    This is driving me nuts. I LOVE this computer, but I have WAY more invested in music than the cost of the computer.
    Thanks in advance.

    It took a while to figure it out but apparently there was a conflict with bluetooth. I disabled it and all is well.

  • After upgrading to Mountain Lion, my LaCie USB 3 drive will not mount

    I just upgraded my OS to 10.8 and now my LaCie P'9230 USB 3.0 external drive will not mount. I have re-installed the USB driver and re-booted the computer and drive several times to no avail; any ideas/help?

    It's my understanding that LaCie hasn't released a Mountain Lion driver for their PCIe card yet. Sonnet uses a modified version of the LaCie driver and theirs is dead in the water too for that reason-they also warn that their driver won't work with 10.7.5 when it's released.
    Indeed, yesterday I pulled the Sonnet USB 3.0 card from my Mac Pro and replaced it with a CalDigit card from OWC; CalDigit has separate drivers for 10.6, 10.7 and 10.8 and I can say that the card works with all three, the first time in 1.5 years that I've had a reliable USB 3.0 connection.

  • How do I repair a hard drive that was being written to while my MacBook Air crashed? (Drive will not mount)

    My external backup drive will not mount. I have tried to mount it in Disk Utility via the app and the command prompt but the attempt times out. Any suggestions?
    I backed up my HD the day before dropping off my Mac for repair, and then tried again just before going to my appointment. During this last and final backup my Macbook Air crashed. I have since discovered that the drive will no longer mount, likely due to the crash that occured during the last attempted backup. I am unsure if the drive can be repaired.
    My logic board was short circuiting some where that controls the headphone jack. Initially this prevented me from using the jack but eventually caused my mac to crash several times before I brought it in for repair. I believe that it is the this crashing that is responsible for my back up not being accessible but that my data may still be intact.
    Thanks for any help you may have!

    If possible, attach it to another Mac and see if it is recognized in Disk Utility.  If so, run Disk Utility>First Aid.  If not, the HDD may be damaged.
    Ciao.

  • Hard drive will not mount shows up in Disk Utility

    I have an external drive with a bootable OS X 10.6.8. I was in a transition between building up a SSD swapped drive. The SSD is installed in the CPU box but I have my old installation running from an external.
    I have several external hard drives. They are all Firewire. Some have USB 3.0 and or eSATA options but my MacMini only talks to Firewire and USB 2.0.
    I understand that you daisy chain Firewire drives and turn them on and off in sequence as they fall from the CPU box/case.
    Firewire is a power source. I run the external with the OS using an AC adapter but one Firewire drive is powered through Firewire.
    I have had as many as 4 external drives running along with the internal drive without a glitch while I was reorganizing files.
    Today I booted off the external drive. It was running fine. I turned on one Firewire drive (the one that runs on Firewire power). That drive stumbled. I recognized the sound when there is an interruption in power. This cause the external boot drive to stall. I had to force a reboot.
    Now the external boot drive will not boot up. It does not mount but Disk Utility sees it. The drive itself is bright and clear in Disk Utility but the partition (single) is faded out. I can run Verify and repair in DU. DU says it doesn't see anything to repair. It will not mount on its own or when I click the Mount button in DU. It does not produce an icon on the Desktop (because it is not mounting).
    I also have SpeedTools. But although it sees the drive I cannot do anything with it. None of its tools run more than a spli second before they fail.
    This drive has USB 3.0 and I see everything through USB that I see through Firewire. Connecting the other way did not get around the problem.
    Of course I will buy an AC adapter for every external drive and never run them using Firewire again but the horse is out of the barn.
    I have the original installation disks and could run the Archive and Install option but it would require physically swapping drives with the internal. I'd like to avoid it if possible. It is a MacMini and tedious.
    Any suggestions?

    I took the problematic hard drive and installed it in my Mac Mini so I could attempt a Safe Boot and then Archive and Install if necessary.
    Safe Mode didn't work. The drive produced the circle with a slash symbol.
    I reset the PRAM which was part of a list of steps to work through I found created by Apple Support.
    I was able to boot up to Verbose Mode and view the text of the boot process. I wrote it all down. I can answer questions about the content better than typing it all out exactly. It includes, "...journal magic is bad..." "...failed to open..." and ends with "...cannot mount root, errno = 19"
    I attempted Archive and Install however when it went to show what target drives were available it was a blank box and all buttons were grayed out.
    I rebooted and opened Disk Utility from the DVD. The drive appeared the same with the top main line bright and the partitioned volume faded. Still was unable to mount. I ran Verify and this time a red line of text appeared "Invalid content in Journal" and at the end I ran Repair. When running I could read line by line and at one point it showed "checking volume information" then the following line "Repairing volume" the following line "Rechecking volume" more line of checking then it ended with "The volume was repaired successfully."
    It still would not mount. I ran Verify again and again said "Invalid content in Journal" and this time it stopped midway saying "The volume was found corrupt and needs to be repaired. Error: This disk needs to be repaired. Click Repair Disk."
    I clicked Repair and it ended with The vol. was repaired successfully."
    Still unable to mount I began repeating Repair over and over. Each time it found something to repair and ended with a success message. After several more Repairs I tried Verify and it stopped midway saying to Repair the disk.
    Question: Does running Repair multiple times continue to correct bits and pieces little by little or is this a generic message and we should treat it as a problem Disk Utility cannot pinpoint and is just beating its head against the wall?
    The step by step instructions I downloaded mentioned running Repair more than once but it did not say that running it 20 times would erode some problems and eventually lead to a fully repaired disk (if the problem was something DU could take care of in the first place). At this point I have run Repair about 20 times total with a series of 10 back to back skipping Verify. I keep seeing the lines about invalid content in a journal and that it repaired something successfully. Yet I still cannot mount the disk.

  • Hard Drive will not Mount

    I have a Seagate Barracuda 1.5 Gig installed in a MacPro as an additional drive and as of today the drive will not mount.  Yersterday I noticed it ejected itself; I immediately rebooted and started to download the data to another drive but it ejected itself again after about 25% complete copy. I attempted to "verify drive" with Disk Utility but it was not listed.  This morning it will will not mount.  The drive is still under warranty so replacement is not an issue.  Where I am at a loss is recovering the data.  I fired up time machine and there was no data from this drive backed up (Bay 2).  I checked the preferrences and the drive was not "excluded".  So, I'm at a loss as to how or if I can recovery any data.  I removed the drive from the MacPro and fired it up in a docking station (SATA) without results; still will not mount.  Is recovering my data beyond hope? Any ideas or tips would be appreciated.
    Thanks,
    Koyangie

    Hatter,
    Tried Recovery Mode without success.  Although the drive appears in Disk Utility I get an error after selecting Restore!  If I click on the Image icon it will not list the contents.
    There is perhaps .6 TB on this driver (images).  After I posted and received yourt reply I took another look at my Time Machine and found all my data under Shared.  What a relief.
    Thanks for your advice. I'll return the drive to Seagate for a replacement.  Hopefull I will be able to format it before sending it back.

  • External drive will not mount to desktop

    Ok so i just bought a new hard drive and hooked everything up to my imac. However, it will not mount to my desktop.
    1. I opened disc utility and i can see that my newly purchased hard drive is listed on the LHS with 931 GB available.
    2. I click on the mount button on the top and i get this message- "The disk “disk1s1” could not be mounted. Try running First Aid on the disk and then retry mounting."
    3. So now i click on First Aid and attempt to repair disc, however I get this message-"Disk Utility stopped repairing “disk1s1” because the following error was encountered: Filesystem verify or repair failed."
    Does anyone have any idea how to fix this problem?
    Thanks in advance.

    how did that solve the issue? my 350gb seagate drive just started behaving the same way as your initial post -- it shows in Disk Utility but will not mount -- even after running disk repair/verify. This just started happening two days ago...

  • External backup drive will not mount on new mac mini. still works fine on the old one. new one is running mavericks

    I just bought new-to-me mac mini running OSX mavericks.
    Trying to migrate from old mac mini using simpletech external hard drive.
    It still mounts on my old mac mini (system 10.5) but will not mount or show up when I plug it in to the new mac mini running mavericks.
    Any ideas?

    What exactly shows in System Profiler>Hardware>USB for those drives?
    Boot from the Install Disc & see if they show up, not grayed out in Disk Utility.
    1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
    2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
    *Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
    We were thinking along the same lines. While at home I dug up a firewire enclosure and put a bootable GUID formatted drive in it (that I had in one of the usb enclosures) and started her computer holding down the option key and then chose to boot from the external firewire. All usb drives are now mounting upon connection. I asume that her drive has bad sectors on it (even though the SMART status says it's OK) and is not loading all the drivers properly for USB to mount. I was suspicious from the beginning that the OS was corrupt when she first had me look at it. It was at that point that I booted it in target mode, connected to my Macbook Pro, and then CCC'd to a usb drive that I had. I then had a couple of difficulties installing the new OS. Should have known......
    I am now going to put a new drive in it for her and she'll be up and running.
    Thanks so much for your help and thoughts that got me thinking as well.

  • Hard drive will not mount with 10.4 but will mount with 10.3

    I have a G4 powerbook running on 10.4.11. There is a western digital my book external drive hooked up to the USB port. I have two partitions on it. I tried to change the group settings to read write and got an error saying I did not have permission. Now the first partition will mount, but the second which I tried to change will not mount.
    Disk utility sees the drive but it is grayed out. DiskWarrior sees the drive.
    I dragged out my old G3 running 10.3.9 and plugged it in. Works great. The disk drive partition mounts and all of the files are there. What do I need to do to get 10.4.11 to mount the disk partition?
    The external drive is a Western Digital My Book 250G divided equally into two partitions. The partitions are in Mac extended format.

    I'm having pretty much the same problem... Have a WD 500 GB external attached via USB. I can't say for sure that the WD caused this (wasn't paying close enough attention), but I've noticed that my own MacBook HD is no longer mounted. I can't seem to find anyway to accomplish this either. I've booted from another volume to run Disk Utility (repair/verify). I rebooted with the MacBook startup drive and still, no HD. And NOW I can't see the bootable partition I made on the WD external. What?
    I feel like the opposite of a nerd, cuz I'm just scratching my head at this point. Oh yeah, and running 10.4.11...

  • External Hard drive will not mount on Macbook Air (mid-2011) OSX 10.9.4

    Hello Everyone!
    Needs some help resolving this issue.  External hard drive (Toshiba v63600-C) will not mount anymore on my mothers-in-law's macbook air.  She notice this problem starting on the Aug 6th.  You can see it in the Disk Utility but is not mounted.  I can get the her ext hard drive to mount on my Macbook Pro with no problem.  I also tried my personal ext hard drive (Seagate) on her Macbook Air and it will not mount.  Not sure what is going on here.  Any help is appreciated in resolving this issue.

    You may believe this is Apple's problem but I just like Baltwo have had absolutely no problems with any of my Firewire drives in Lion. So unless you can come up with much stronger evidence to the contrary, I doubt that your feeling are going to carry any weight at all.

  • External hard drive seen in Disk Utility, but will not mount.

    My external hard drive has power and is spinning, but will not mount.  It was fine yesterday.  It shows up in Disk Utility and is verified and repaired.  Tried the drive on 2 other macs with same result.  Tried a new enclosure and that did not work.  Tried all ports...usb and firewire.  Any way to save my data?
    I have screen shot of the partition info from Disk Utility for the hard drive included:

    Hi Dominic,
    If this is still not mounting, it may be worth trying a PRAM reset...

  • I have a lacie drive attached to my airport but it will not mount

    I have an Aiport Extreme and I just purchased a Lacie 2d Quadra drive to attach to it. However, it will not mount. I have tried to power it off and on, replaced the USB cable but it will not wake up. The blue light will flicker for a moment then go dark. I have a new MacBook Pro but I cannot connect to it. Any ideas? Thanks.

    Hello,
    This arrow next to your Battery symbol at the top of your phone means you are playing some sort of music or sound.
    To make sure you are not do the following:
    Press your Home button twice quicky
    You should now have a list of open apps. Hold down the App and press the red button. This does not delete the app but it closes it.
    Once these steps are complete if the arrow is gone, you are all set!
    Regards,

  • External USB drives will not mount under Mountain Lion

    Since upgrading to Mountain Lion, two external USB2 drives that I have will not mount and cannot be viewed in the Finder.  The same occurs on a 2012 MacBook Air, a 2009 iMac 27 and a 2010 MacMini, all running OS X Mountain Lion version 10.8.2.
    Both drives are Samsung Story external USB drives (one is 1.5 GB and the other is 2 GB) and both have been formatted using Mac Disk Utility with a single Mac OS Extended (Journaled) partition, one using Snow Leopard and the other with Lion.
    Both still mount correctly on a friends MacBook Pro that is still running Snow Leopard, and I had no problem with the same drives under Lion.  Interestingly both can also be connected to Time Capsule USB port and show up correctly.
    Both drives mount correctly under Windows 7 on BootCamp partitions that I have on both the 2012 MacBook Air, a 2009 iMac 27. These BootCamp partitions have Paragon HFS+ installed so I can read Mac formated drives.
    Both drives show up in Disk Utility, but when attempt to mount the drives I get the message "The disk could not be mounted.  Try running First Aid on the disk and retry mounting." I can run Repair in First Aid on the disk and get the message that the volume appears OK, but again have the same problem when I attempt to mount the disk.
    I have also tried using Disk Utility 3,2, but still cannot mount the drives, though the program indicates there is no problem with the drives.
    I have other portable USB including a Samsung portable USB2 drive, and two external USB3 drives, and I don't have problems with them.
    There is clearly a problem with Mountain Lion with accessing (mounting) these Samsung Story USB drives, and the problem appears to be with Mountain Lion itself as the problem did not occur on the same Macs with Lion and does not occur with Bootcamp partitions on the machines.
    I have a lot of time searching forums, but I have not found anyone with an identical problem.
    I sure hope someone can help or that Apple come up with a fix for this issue which has only developed since the update to Mountain Lion.

  • OWC Mercury ext. drive will not mount via FW 800

    Hi,
    I just tried to hook up my OWC Mercury ext. drive to my new Mac Pro via FW 800 on the back panel and the drive will not mount. It does not show up using disk utility. Any suggestions would be greatly appreciated. Thanks, Mike

    Try shutting everything down, and unplugging everything for 10-15 minutes.
    Then, plug things back in in this order: the external drive firewire cable at both ends; the mac's keyboard and mouse, then the AC power for the mac and the external drive, and lastly, anything else you have hooked up.
    Turn on the external drive first, then start up the mac and see if it shows up.
