My external HD will not show up on my desktop anymore. I'm on macbook pro 13", OS 10.7. It doesn't show up in disc utilities, nor on another mac, nor on that mac's disc utility. I happened to restart the comp while the HD was connected.

My external HD won't show up anymore on my desktop nor does it get listed in disc utilities. I tried to cennect it to another mac but it doesn't show there either nor in that mac's disc utility. I happened to re-start the computer while the hd was connected and now it doesn't show up anymore. I use it for back-up via Time machine. I could re-format and do the back up all over again but then I need to find it first. Please, does anyone have any solution to this problem?

It sounds as though the external drive may have failed. There's nothing at all wrong with restarting your computer with the external drive connected -- that's a perfectly reasonable and normal thing to do, done by countless users every day without any ill effects.

  • Keyboard lights will not stay off no matter what I do on my MacBook Pro. Why??

    I've got a MacBook Pro 2.4 GHz Core 2 Duo.
    I have ALWAYS left the keyboard lights off for the 4 years I have had it.
    But lately, no matter what settings I change or what I try, I cannot PREVENT the keyboard lights from coming on when I've been away from the computer for a long period of time.
    Automatically illuminate keyboard in low light is NOT checked in System Prefs. I have reset the PRAM, and left the laptop off with the battery off for hours in hopes of resetting it.
    Nothing will work. Almost every time I am away from my computer for hours, I come back and the keyboard lights are on. And when I tap the keyboard light brightness buttons, it just gives me the buster symbol (white circle with a line through it) on screen below the keyboard light brightness indicator for a few seconds. Somehow continuing to tap those buttons eventually makes the lights just turn off. Or holding my hands over the whole keyboard to trigger the sensor can suddenly allow me to control the on/off brightness with those buttons again. In which case I try turning the lights off completely or turning the brightness so low that it goes off.
    But once again, when I wake up in the morning, I find the keyboard lights on.
    Now the ONLY thing that has changed since this started happening is that I added a new User account. BUT that should asbolutely not cause this problem. I have checked to see if the System Preferences for the keyboard lights in the new user account were causing a conflict, but no, they are exactly the same as my main account.
    I have not tried deleting the user account yet because I actually want it and would find it very hard to believe that was the culprit. It's just the only thing I can think of that changed shortly before this started happening.
    Is there anything else I can do!?! Is there some preference file that controls the lights somewhere that could be corrupt that I need to trash?
    Thank you for any help anyone can provide. This one has stumped me good.

    From reading up of other forums with the same problem i have come up with two reasons why it is doing that.
    first try doing a smc reset
    if that does not work then it is a hardware error. Many people have had the problem and they have not been able to fix it so good luck

  • HT1349 My one week old iphone 4S went dead and will not turn on even by plugging into wall outlet or MacBook Pro, besides taking back to Verizon is there anything I can do?

    I have a week old Verizon iPhone 4S and it went dead and I have tried plugging into the wall outlet and into a MacBook Pro and pushed all the buttons but nothing. Besides taking back to Verizon is there anything I can do?

    Thanks. I also found that holding the home button and on/ off button at same time for 15 seconds turned it back on.

  • External Clone will not Boot PPC Mac

    I have a ppc mac running OS 10.5.8 and an external hard drive, formatted  with APM and containing a clone of the ppc mac. Using the firewire interface, this external drive will not boot the computer. The external HD box is an OWC Mercury Elite Pro containing a 2 TB Seagate Barracuda HD with 2 partitions, one partition containing the clone.

    Does it only happen using FireWire? Have you checked if the external disk has got an Apple Partition Map? Note that it's required to start a PowerPC-based Mac.
    To check that your external disk is using Apple Partition Map, connect the external drive, open Disk Utility and choose the external disk in the sidebar. Then, look at the bottom of the window and see what says next to "Partition Map Scheme"

  • External Monitor will not display full view MS apps.

    I have a HDMI monitor that was previously working fine.  The other day I went to use Word and Excel and the applications would only appear in the lower toolbar.  When I would select them they would not enlarge.  They remained in a thumbnail view.  My email and Internet work as expected.  Any ideas what's causing this?

  • External HD will not Boot PPC Mac

    I have a ppc mac running OS 10.5.8 and an external hard drive, formatted  with Apple Partition Map and containing a clone of the ppc mac. Using the firewire interface, this external drive will not boot the computer.
    Any suggestions on troubleshooting this problem would be greatly appreciated.

    A few drives don't support booting a Mac at all.
    If you have a Western Digital model, here's a list showing which ones should, or should not, boot Macs: http://wdc.custhelp.com/app/answers/detail/a_id/1787
    If you have another make, check with the maker.

  • External drives will not mount if wi-fi is on

    I was really unsure where to post this. If you think it should be in a different thread then let me know.
    My problem is this. I have a Macbook that I use at home no problem. I teach at a college where there is a wi-fi connection that my Macbook automatically connects to. Recently, I have discovered that any external drives will not mount until I switch the wi-fi off. Additionally, almost everything I try and do causes the spinning beachball for 10 minutes or more at a time.
    I have searched the net and cannot seem to find any reference to this problem anywhere else. Any ideas at all why this might be happening will be much appreciated.

    It was not until Mac OS X 10.6.4, not possible to run on a 10.2 machine, that ExFat was supported.
    Many older Macs also will not recognize GUID formatted partitions made to boot Intel Macs either.
    10.2.3 is the first system to support Apple Partition Map HFS Extended (Jornalled).
    There may be NTFS support based on my tip here:

  • External drives will not mount if the wi-fi is on!

    I have had no replies where I had previously posted so I thought I would try here as I think that it is mainly an Airport problem.
    My problem is this. I have a Macbook that I use at home no problem. I teach at a college where there is are two wi-fi connections that my Macbook automatically connects to depending on where I am in the department. Recently almost everything I try and do causes the spinning beachball for 10 minutes or much more at a time. Additionally, I have discovered that any external drives will not mount on my laptop, unless I switch the wi-fi off! No-one else is having any problems at all.
    One of the wi-fi connections is an Airport Extreme. Each morning my laptop gets the message that there is a problem and I need to update the firmware to 7.5.2. (I originally set the Airport up through my laptop) I am very wary of doing this as everything is working fine for the other 20+ laptops in the department and I have read lots of reports of problems with this update.
    I suppose my questions are these - 1 Does anyone have any idea what is going on with my laptop? 2 What should I try doing to solve this issue?

    I Have the same issue on a brand new iPad mini 2. My battery is only lasting up to 5 hours. I went on chat with Apple last night and they said my battery is fine and its a Safari issue. I'm literally losing 1% every 3-4 minutes. I tried recalibrating my battery, signing out of iCloud, shutting off all locations, turning off background app refresh, restoring network settings, restoring all, and finally restoring from iTunes with no luck. This is just awful. I got this iPad so I could use it on my long flight for a trip I have coming up, and unfortunately, it's not going to last that long, plus I'm concerned about how many times i will be recharging my battery because of this since battery's do have a life cycle dependent on the number of charges. This is frustrating and needs to be fixed ASAP and addressed by Apple.
    By the way, Apple told me to bring my device to the Apple Store because it's still under warranty. That's great and all, but I'm going to waste my time if there is no fix for this issue.
    Ok so you want Apple to address the problem, but yet you don't want to take it to them just in case they can't fix it? What if they can fix it? Complaining here certainly won't fix it.

  • I am interested in buying a macbook laptop. I am confused however in which one I should buy for the type of work that I will be doing. I either am looking into getting a macbook pro or the macbook air. I am leaning more towards the air.
