I can't get my external hard drive to read

Since I upgraded from snow leopard (or maybe even the one before that) to Lion it hasnt worked.  It still lights up and sounds like its running but it wont show up at all. All of my USB ports work but it wont read at all

Does it show up in disk utility?

  • How can I get by external hard drive to be seen by other computers on the Airport Extreme Network

    I purchased and installed an Airport Extreme yesterday.  I finally got my computers to find it, but I cannot get my wireless laptop to connect to the external hard drive that is connected to the AE using a Cat5 cable.  I have already verified that the Cat5 cable IS good so please don't advise me to change the cable.  I am 36 hours into my purchase of the AE and ready to take it back to the store because it is NO WHERE as good as the sales rep reported it to be. 

    An ethernet connected drive is actually not part of the AE setup.
    It is merely a client on the network.
    So the first chore is to find it.
    I saw in your other post it is iomega device..

    A few questions..
    Other computers can access the network hard disk??
    What OS is on the computer that is having access difficulty?
    Can you please ping the hard disk.. on a Mac open the terminal and type ping followed by the address.
    Or on a PC open the windows command and type the same thing.
    Does the hard disk respond to ping?
    Try mounting it directly in Mac by using Finder, go, connect to server.
    SMB://IPaddress
    Or CIFS://IPaddress or AFP://IPaddress
    In windows type the address directly into the windows explorer address bar
    \\IPaddress

  • Can't get my external hard drive to show up on MacBook Pro

    I used Time Machine to keep backups for my MacBook Pro using the latest version of Lion. I backed up to a WD external drive. My computer went to be repaired and they had to put in a new hard drive. When I got home and plugged in the external drive it appeared on my desktop. The Apple rep told me to drag over folders from the backup. I looked through a few of the backups (dated) and everything seemed to be there. But I got the spinning wheel as I tried to copy over "latest". I couldn't get rid of it and had to reboot.
    So next it appeared, showed one folder but when I clicked on that folder there was nothing inside.
    Then I couldn't see the hard drive any longer.  Now I take out the drive and plug it in again and the drive won't appear in the list of devices. I use the disk utility and it doesn't see it either.
    Needless to say I'm pretty concerned. I've had the problem of an external drive not appearing a few times over the years but a reboot or unplug and plug back in always fixed it. not this time.
    Help!
    Much appreciate,

    If you have recently upgraded to Lion, it would be probably a matter of drivers. You should go to the official web site and download the latest drivers. If not, try to format the HDD with disc utilities. If your disc doesn't appear even in disc utilities, try to format it with any copy of windows in fat 32 format

  • Can I share an external hard drive and simultaneously have it connected via firewire to my iMac?

    Trying to get an external hard drive that is connected to my Airport Extreme to also be connected to my iMac via firewire 800. Any ideas?

    That shouldn't be attempted. Unless the drive is specifically designed for it, which very few drives are, connecting it to more than one computer(which includes the base station for this purpose) at any given time through USB or FireWire can damage it.

  • HT1766 Can you use an external hard drive to back up my movies in iTunes but still be able to access them or is there a device so I don't have to use a pc ??

    Can you use an external hard drive to back up my movies in iTunes but still be able to access them or is there a device so I don't have to use a pc ??

    You can store them on a separate hard drive, you don't need to keep them on your laptop's hard drive. On your computer's iTunes on the Advanced tab in Edit > Preferences there is a 'copy files to iTunes media file when adding to library' tickbox - if you untick that, you should be able to copy the films to a separate drive and add them back to your iTunes library (File > Add To Library) and it should then point to them on that separate drive and not copy them to your hard drive. When you are happy that it is what is happening and that they are safely on your external drive you can delete the films from your laptop's hard drive.
    If you plug the external drive into a different USB port next time (assuming that your laptop has more than one) then it might get a different drive letter, so you might need to always use it with the same port.

  • I would like to know if you have to back up a macbook hard drive, can I use a external hard drive that has been previously used to back up several pc 's, or is it best to have a separate external drive for the Mac?

    I would like to know if you have to back up a macbook hard drive, can I use a external hard drive that has been previously used to back up several pc 's, or is it best to have a separate external drive for the Mac?

    In the Mac side of things, backups usually come in two flavors: clones or incrementals.
    A bootable clone is a bit-for-bit copy of all essential files in the startup volume. If using the Lions, clones can be made using CarbonCopyCloner or just plain old Disk Utility. These backups represent the safest protection of your info, but take the longest to do. Recovery is an inverse process: you copy the clone back into the internal drive.
    Incremental backups start with a complete backup of the startup volume and only copy whatever changed from the previous run. OS X includes the fully integrated Time Machine backup utility to do this. It is extremely easy to do and takes the least amount of time. Recovery is another matter altogether since you have to start with a freshly installed instance of the OS and have to apply all intervening backups to bring the result to the latest saved version.
    As for where the backup takes place, the recommended media is an external dedicated drive or drives connected via the fastest interface available on your Mac: Thunderbolt, USB3, Firewire, or USB2. Network-based backups, wired or wireless, are attractive but may not offer the same performance and hence take longer. Also important to note that the entire drive need not be completely dedicated to a single backup. The Mac's EFI firmware infrastructure allows for an unlimited number of partitions on a hard drive and each can be used for either type of backups.
    Holler if you need specifics on how to do each. This was just an executive summary.

  • Can I use one external hard drive for 3 of my Macs?

    I have a 2007 white MacBook, a 2011 MacBook Pro, and a 2013 MacBook Air.
    I want to be able to transfer all of my precious family photos off of my MacBook and Macbook Pro onto an external hard drive and then wipe those computers clean, and then I want to be able to backup and wipe clean my Macbook Air so that I can update it to Mavericks.
    Can I use one external hard drive to do this for three of my Macs? Will it be compatible with all of them? And will I still be able to use the hard drive with my Air once it is updated to Mavericks?
    Which hard drive do you recommend?

    1. Yes. Note that anything you want to keep should be on at least two drives in case one of them fails.
    2. Yes.
    3. Yes.

  • How can I use my external hard drive for my iphoto instead of my mac book pro memory?

    i don't know if this question has been asked before: how can I use my external hard drive for my iphoto instead of my mac book pro memory? just like itunes all my song are save on my external hard drive. make sense?

    Moving the iPhoto library is safe and simple - quit iPhoto and drag the iPhoto library intact as a single entity to the external drive - depress the option key and launch iPhoto using the "select library" option to point to the new location on the external drive - fully test it and then trash the old library on the internal drive (test one more time prior to emptying the trash)
    And be sure that the External drive is formatted Mac OS extended (journaled) (iPhoto does not work with drives with other formats) and that it is always available prior to launching iPhoto
    And backup soon and often - having your iPhoto library on an external drive is not a backup and if you are using Time Machine you need to check and be sure that TM is backing up your external drive

    Ok, fair enough.  But since Job's death - Apple's control on leaks has been terrible.  I got the new iPhone, and I like it - but it hasn't made nearly as big as an impression as previous ones.  Because of the vast ammount of leaks.  With the iPad mini leaks, it's 99% sure to come out next week.
    Apple uses many manufacturers and it's massive also websites prefer to report on Apple whether true or false because it brings more hits.
    Amd by "others" I meant other people on iPads - not other devices/manufacturers.  It's possible to do so, I just want to know how.  I honestly don't think we'll ever be in a Post-PC era until all tablets allow us to use USB in the way computers do.
    No, USB is not the future, you missed the memo about cloud and wireless computing?

  • I recently had the genius bar change my imac hard drive because it crashed. For some reason Time Machine didn't back up some of my important files. Can I get my damaged hard drive back from the genius bar to see if I can access that info?

    Unfortunately, that drive is long gone, probably back to the mfr. Drives are not returned when they are exchanged. You can go by and ask them, but the chances are slim to none.
