Recognising external hard drive

I just got my laptop wiped at the mac store, because it was slowing right down, but now it won't recognise my external hard drive any more! is there anything I can do to get it recognised again? Just to clarify, before I wiped the laptop, the hard drive was recognised, and has all my document back up. Help!

  • Recognising external hard drive problems

    My new Macbook Pro won't recognise the external hard drive I'm trying to read. The external EIDE interface HDD is from my dead G4 Powerbook (OS X 10.4.2) and it is in a 'Mobile Disk' external data storage case that is allegedly compatible with Macs. The instruction booklet says that the necessary software is on my version of OS X (10.6.5) and that "all devices must select and jump to Master Mode".
    I've plugged in but my macbook pro cannot see the external HDD, although it is ok with my usb flash drives. Can anyone help? How do I get my macbook to select and jump to Master Mode and then recognise the external HDD

    The "select and jump to master" comment is an instruction for you to do with your hardware on your notebook EIDE drive. The drive has a 44 pin connector, of which 40 pins are used for data, and the other 4 are generally used for setting Master/Slave/Cable Select, just like with a desktop drive. You need to determine which pins to short together to force the drive into "master" mode. That is usually drive specific, so you would need to get that info from the support site of your drive's manufacturer.

  • Won't recognise external hard drive.

    Hi there I don't know If this is the right section, If not please forgive me.
    Right I have a MacBook an I connected my external hard drive to it for time machine. I have windows installed on my laptop an I wanted to transfer a few files between the partitions so tryed connecting the hard drive, but it doesn't seem to sense that it's connected. It recognises mini USB sticks so it's not a USB problem.
    Has anyone experianced anything else like this? An know how I can get windows to recognise my HD?
    Thanks for any help u can give

    Windows can't read Mac Extended formatted drives (which is the drive format that Time Machine requires). Two options are: either connect the drive back on the Mac, and use network sharing, or purchase MacDrive if you think you'll need regular drive sharing between the two machines.

  • ITunes on Macbook Air doesn't recognise external hard drive once ejected

    I just bought  MacBook Air less than two weeks ago and I'm loving it and I successfully mapped my iTunes to my music library, which is stored on an external hard drive. Howeve, whenever I eject the external hard drive to use the MacBook Air in a mobile setting and then reconnect it, my iTunes doesnt remap to the library. This never happened on my PC so I was wondering if there was a work-around/solution and if this is a common problem?

    Think ive just found the problem.
    It seems as though I needed to "unlock" the hard drive by useing the unlock icon in the WD icon on the desktop.
    I forgot I had made a password for it and also didnt realise I had to enter the WD software that comes with the hard drive which automatically appears on the desktop when you turn it on or plug it in.

  • Mac won't recognise external hard-drive

    Hi there,
    I've just tried to transfer some files from my external hard-drive which I usually use with my OS 10.5, onto another PC, and was unsuccessful. Then when I plugged the hard-drive back into my mac, the device doesn't appear on screen as it usually does. I've also looked in my computer and the hard-drive isn't showing and I can't access any of the files on it. Does anyone know how I can resolve this issue please? Would really appreciate some help!
    Thanks.

  • Power mac G5 wont recognise external hard drives

    running a friends power mac g5 using tiger 10.4.6 since the upgrade firewire hard drives arent visible. have tried three different hard drives using differenty ports and different cables. drives will power up but wont appear in the finder. any suggestions??

    Yes, visit the drive makers sites for any driver software updates and run it.
    Also it's not advised to upgrade Tiger over Panther, but to do a fresh install of Tiger and iLife '06 from scratch on a Erased w/Zero option hard drive.
    Use Software Update download then run option/combo update until your up to 10.4.6.
    Then avoid Migration Assistant and do fresh installs of all your Tiger ready applications from original sources, files from backup.
    Then clone that boot drive to a external for safe keeping, learn how by visiting Carbon Copy Cloner's free advice forums and donationware software.

  • IMac won't recognise external hard drive

    My iMac with OSX 10.8.4 won't recognise my external disk drive via either Firewire or USB Cable. It also doesn't show up on desktop or in Disk Utility. Disk drive and cables work fine with my old computer on Snow Leopard. It also wouldn't recognise my old computer via Firewire, when I tried to migrate info across to it (this was before updating system to 10.8.4). However, flash drives show up fine. Any suggestions?

    The EHD is a 2.5" WD SATA
    Two things:
    1) WD drives are fine. It's their enclosures that are useless. I had a desktop WD drive that was nothing but trouble with an older PPC Mac and a newer Intel iMac. Stalled, overheated, and generally made it impossible to use Time Machine.
    I ripped the WD bare drive from the enclosure and dropped it in an OWC Mercury Elite Pro and now the WD drive that apparently was the Devil's Own is working flawlessly.
    2) Drives that must get all their power from the USB cable can fail to be recognized. As electric motors wear, they can demand more powr. Eventually they need more power than any USB port can provide.
    Always get a desktop drive for a desktop computer. Having suffered through serveral "Name-brand" external drives, I now spend the extra money for the OWC products. They are made for Mac and very reliable.
    Possible fixes for your old drive:
    1) First, make sure the computer is set to "see" the drive. By default, it is not. While in the Finder, open Finder Preferences and make sure "External Disks" is checked:
    2) Reformat it as "Macintosh Extended (Journaled)" with Disk Utility. That often wakes up the drive.
    3) Get a POWERED USB hub. It makes up the power the drive can't get from teh port.

  • Time capsule won't recognise external hard drive, even when formatted correctly and connected to a powered USB hub

    Hey
    i have an apple time capsule (not the very latest one, but the one before that) and i am trying to connect my 1.5TB toshiba hard drive to it. i understand that it needs to be powered, so i purchased a usb hub ("usb hub man" by Gadget Geek) and bought an adapter to power it.
    The hard drive won't show up in finder or disk utility, however i can see it in airport utility.
    it is formatted correctly - Mac OS Extended (Journaled, Encrypted) and works perfectly fine from my macbook pro usb port.
    Also, when i connect a smaller hard drive to the hub (16GB) that shows up in finder as normal.
    so it seems that everything is perfectly fine, however this 1.5TB hard drive just wont show up in finder.
    Does anyone have any suggestions as to why this is the case? my guesses are that i need to get a better quality usb hub, or that i might have to get a powered hard drive altogether rather than trying to power it with the hub.
    Thanks

    The hard drive won't show up in finder or disk utility, however i can see it in airport utility.
    You would not expect it to show up in disk utility .. it does not work on network drives.
    Finder may or may not be able to see it.
    If the airport utility is showing the drive you have some possibility.
    Did you GUID partition the drive .. or is it still MBR.. ie if it was originally formatted for PC it will be MBR and won't work.. so put it on the Mac again and change the GUID partition.. I would also set a smaller partition size.. the internal drive of the TC is partitioned though you cannot see them.. put a first partition less than 1TB and see how it goes.
    In finder.. don't forget ML has issues with network drive.. make sure you tick all the extras in finder preferences.. and if the drive won't mount try to do it manually.. go .. connect to server.
    AFP://TCname or TCIPaddress.. where you use the actual name or IP.
    Also is the power supply for the hub at least 2A preferably more.. so the hub is powered but the disk is not powered??

  • Macbook no longer recognises external hard drive

    Hello,
    My Macbook Air doesn't recognise my HDD when I plug it in, however my dell laptop does.
    When I plug it in the light of the HDD turns on and starts 'working' normally (no bizarre noises).
    When I open my parrellel network, Windows recognises it however I still cannot access the files or open it in a window.
    Any recommendations?
    Thank you

    One, post this in a forum that handles hardware, not the Pages for Mac forum.
    It sounds like you may have your HDD formatted in something unusual. Like a Linux format perhaps?
    With the drive plugged in, open Disk Utility and see if it recognises it and tells you what the formatting is. Don't reformat it or you'll lose all your content.

  • Why won't my iMac recognise external hard drive?

    Ever since I updated to OS X my passport cannot be recognised though other memory sticks are.
    I am given the following message though unfortunately means nothing to me - any help?
    NTFS-3G could not mount /dev/disk1s1
    at /Volumes/My Passport because the following problem occurred:
    /Library/Filesystems/fusefs.fs/Support/fusefs.kext failed to load - (libkern/kext) link error; check the system/kernel logs for errors or try kextutil(8).
    the MacFUSE file system is not available (71)

    Sounds like something in your OSX is missing or corrupted.
    I would re-install OSX. Do nto format, just re-install. Its always best to backup first.
    Youcould also paste some of the error into Google or Bing and see what you can find.

  • My Toshiba external hard drive is no longer being recognised by my Macbook Air - solution?

    My Toshiba external hard drive is no longer being recognised by my Macbook Air. The light on the hard drive is on, but it won't appear on my computer's desktop or anywhere else. How can I fix this?

    Hi rivraff,
    If you are having issues mounting an external hard drive volume, you may want to see if it shows up and/or can be repaired in Disk Utility; you may find the following article helpful:

  • External hard drive which used to be recognised by my new iMac is no longer being recognised?

    I recently bought an iMac. I have an external hard drive which was formatted to my old MacBook Pro. Initially it worked fine on my new iMac, but all of a sudden it is not being recognised by it. Any ideas what I can do?

    The drive is probably probably starved for power. As electric motors age, they can demand more power. Get a powered USB hub and I suspect your problems will go away.
    If you purchase another hard drive for a desktop Mac in the future, consider one that is self-powered. Much less troublesome.
    Some people have reported that, if they reformatted the external drive for Mac (most are formatted for Windows), the existing drive may work without a hub. You can refomat the drive with Disk Utility. Select Macinstosh Extended (Journaled) as the format. This is a great strategy if you do not have to share the drive with a Windows computer.

  • My external hard drive is not recognised on my mac book pro

    my external hard drive is not recognised on my mac book pro

    Hello all -
    similar situation.  Unplugged external hard drive and all to take the laptop on a trip.  On return, I plugged everything back in and keep getting this message:
    Time Machine couldn’t complete the backup to “Iomega_Ext_Drive”.
    Files can’t be copied onto the backup disk because it appears to be read-only.
    You may need to repair or reformat the disk using Disk Utility. If the disk can’t be repaired, you must use a different disk for backups. Open Time Machine preferences to select a different backup disk.
    open time machine preferences.   -
    I tried this and tried "repair" but that didn't work and I still get this message.  Any advice?  thanks
