MacBook :: External Hard-drive Won't Mount Or Be Recognized

May 31, 2012

I just installed a new internal hard drive into my macbook as my old one was failing. Before doing this I backed up all of my information through Time Machine onto a Seagate FreeAgent external hard drive. I've been using this external hard drive for the past two years and I've never had any problems with my macbook mounting it. Once I had all of my personal information backed up I took out the external hard drive and then proceeded to take out my old internal hard drive and installed the new one. I installed the Mac operating system and the Macbook started up just fine but when it came time to reload all of my personal setting using Time Machine my macbook didn't recognize that there was an external drive plugged in. I know it isn't the external drive as it mounts just fine on other laptops. how I can get my macbook to mount the drive so that I can transfer all of my information onto this new internal drive?

Power Mac G5 :: External Hard Drive Not Recognized

Oct 9, 2007

I am a photographer. I use 4 X 1TB LaCie external hard drives to store my digital images. 2 as masters for different business segments and 2 as their back-ups. They are daisy-chained using Firewire 800. Recently my G5 has stopped recognizing one of the drives. Is there any way to get my machine to re-recognize the missing drive? I have rewired the four drives to see if there was a problem with the cabling, but this does not appear to be the case. I am coming up to the 1 year warranty period on this drive and need to get it back to LaCie if there is no other solution.

Intel Mac :: External Hard Drive Not Recognized

Apr 11, 2012

I recently invested in a refurbished iMac which is running Mac OS X Lion 10.7.3 (11D2001).

I am trying to access my existing external hard drive through the machine and although this lights up when plugged in, it doesn't appear in the finder.  Other Memory sticks work without problem.

It is a Western Digital Elements 160GB Portable Hard Drive that has worked and continues to do so without problem on my ancient iBook G4.

OS X Mavericks :: External Hard Drive Not Recognized

Jun 1, 2014

I have used a Samsung HX 1Tb external hard drive under OSX Snow Leopard with absolutely no problem. Since I upgraded to the free (improved?!?) OSX Mavericks my Macbook Pro cannot "see" my hard drive. All I get when I plug it in is the following message -

my MacBook thinks that the hard drive is formatted for windows - but why should it work OK under Snow Leopard but not with Mavericks? I don't want to simply reformat the external drive because I'll lose all the files stored on it.Is there suitable software/Apps that I can use to let my Mac access this external hard drive.Incidentally my partners new Macbook Air can still read this hard drive.

Hardware :: External Hard Drive Recognized On Mac/but Not On Windows?

Jan 20, 2009

I have two external hard drives, one 250GB for my Time Machine, and one 500GB for other stuff. I had accidently formatted my 500GB to use for Time Machine, but realized, I didn't need that much storage, so reverted to the 250GB for Time Machine and the 500GB for storage. But it seems, in the formatting stage (for Time Machine), it set my file system for the 500GB to Mac OS Journaled. I can see this hard drive on the Mac, but it does not recognize it in Windows (although I hear the USB plug in sound, doesn't show up in "My Computer"). Does this have to do with the formatting? If so, how can I format it so that the external hard drives can be read by both Mac OS X and Windows? Does it require moving my data (before formatting?)?

OS X :: External Hard Drive Not Recognized - Unknown Device

Jan 31, 2010

Another one of those "external hard drive not recognized" problems: I am using a Mac Mini. The external LaCie drive is in one of those beautiful boxes designed by a guy named Porsche. It's connected via Fire Wire. I have my iPhoto library stored on it. It was working just fine for the past two days after I first connected it.

Now it does not show on the Desktop. It is identified only as "Unknown device" in "About This Mac." iPhoto doesn't recognize it. I've looked at the other threads on this subject here and have reset the PRAM. Disk Utility recognized it for a while and said the disk was OK. Now Disk Utility does not recognize it at all.

I turned off the drive and turned it back on. That resulted in an alarming series of beeps, almost like somebody was sending the Morse code symbol for "E" over and over again. I turned the drive off and then on again. Now the light goes on and the drive whirs nicely. I am using System 10.6.2. Or rather, at this point it is using me.

MacBook Pro :: Ejecting An External Drive?

Apr 6, 2012

I have a Seagate 500gb GoFlex external drive, which I'm using with Time Machine to backup my MacBook Pro. Now, when ever I eject the drive (by right clicking or dragging to trash) it appears to disconnect from my MacBook, but the drive itself continues running, i.e., the lights stay on and I can still here the fans / drive whirring away. This continues unless I pull the USB cable out. Is this normal? Should the drive completely shutdown upon ejecting? Or is simply 'ejecting' from the MacBook enough for 'safe' removal?

Mac OS X (10.7)

MacBook :: WD External Drive Randomly Ejecting?

Apr 19, 2012

I've seen several discussions on external drives randomly ejecting, but didn't see any concise resolution. I have a Western Digital Passport, P/N WD320ME-01 2209A, using the OEM USB (2.0 I think) cable (~12 inches long). My ~4 year old mac book is running OSX 10.7.3. I use this drive for Time Machine B/U. Seemed to work ok (no ejects) when Leopard was the OS, but, after going to Snow Leopard, and now Lion, I get 'disk improperly ejected' errors when trying to run TM, or ever Repair under Disk Utilities. I did get one good TM back up, under Lion, after reformating the drive [extended (journaled)], but the next time I tried to run TM I started getting the 'improperly ejected' errors. Don't know if there is an issue with Lion (and earlier SL), or with WD drives. The fact that it originally worked leads

MacBook Pro :: New Hard Drive Still Won't Be Recognized

Mar 8, 2012

I've been having several problems with my mid-2009 MacBook Pro; 2 minute beachballs and failure to startup. So I've purchased a new new WD Scorpio Black thinking it was a HD issue, but after replacing my old HD with the WD, Disk Utility wouldn't recognize the new drive. So I searched around and found out that Hard Drive Cable failure is an issue on this certain MacBook. So I ordered a new Hard Drive cable and just replaced that today, thinking that my new HD would be recognized. However after going into Disk Utility via the OS X Install DVD, my new Hard Drive was still not recognized.

OS X V10.5 Leopard :: Time Machine Is Ejecting Hard Drive?

Jun 15, 2012

I'm trying to backup on my G-Mini so I can prepare to switch to a newer OS. I had some problems last tiem I tried this, but it ended up working in the end, this was about three months ago. This time, it doesn't want to work. The drive is attached by a USB.

The three tims it told me it wasn't mounted properly. Then it told me the connection was broken/disk ejected. I retsarted twice, and now I've been repeatedly getting that response. It beings to prepare, then spontanously ejects without me touching a thing.

MacBook :: Trying To Install New Hard Drive - Not Recognized

Jul 7, 2009

I have a first gen white macbook core duo. I am trying to install a new 320GB Seagate HDD in my laptop to replace the 60Gb drive. I installed it but I can't get the OS to recognize the Hard disk when it is installed in the computer. I have no problems when it is installed in an external case. I have booted off the Leopard disk but it does not show a drive available to format, I booted off the original drive in the external case and the disk utilities does not show another drive attached. If I put the 320GB drive in the external enclosure, disk utilities recognizes it right away. I have formatted it with GUID format but it doesn't work when installed directly in the macbook.

OS X :: Unplugging USB Without Ejecting Properly Harmful?

Dec 28, 2007

Is there any harm in just unplugging USB without first ejecting drive? I've got external HD at work I plug in via USB to my Macbook Pro. When I go home I get lazy and would like to just unplug. Is there not a more automated way other than manually ejecting drive before removing cable?

I have been searching the internet for 3 days and finally gave up, besides buying another hard drive. Ill try to keep this short. i got Macbook C2D / OSX 10.4 / 80GB HDD What happened: I wanted to free up space on my macbook, so I removed my bootcamp partition buy using the bootcamp installer to merge the osx and winxp partition back together.

MacBook Pro :: Getting A Seagate Hard Drive Recognized Over WIFI

Feb 6, 2012

I have recently bought a Seagate external drive. It works fine for Windows over WIFI. But for the Mac, it only works when directly connected and is not recognised over WIFI - the drive is not listed under devices.  It did when I first started the drive yesterday, when I managed to copy all my files onto the external drive via WIFI.  But not today.  Perhaps related to the software update I ran last night?

MacBook Pro :: USB Hard Drive Is Not Recognized On It Running Lion

Mar 21, 2012

I have:

- Freecom ToughDrive Pro USB hard drive

- New MBP running Lion 10.7.3 

When I plug the disk in an USB port in the MBP, the light that indicates operation starts blinking but very lighltly colored and the disk is not recognized by the computer. I have put data on it using iMac Snow Leopard. I have plugged the disk into a MBP running Snow Leopard and it works. I have also tried another Lion (older MBP) and it also works. 

How come the disk is not mounted or shown in Disk Utility. Can it be a power issue?

I have noticed there a lot of similar posts in the forum and none has been satisfactorily solved. Is this a mayor Lion bug? If yes, how can I downgrade to Snow Leopard?

OS X :: Hard Drive Not Recognized By System - Hard Drive Not Formatted

Jul 20, 2009

I've just got a new external HD, but it's not being recognised by Mac OS X (10.5.7). I assumed it was because it was in a Windows format, so booted Windows, but it then turned out it wasn't formatted at all. What is the easiest way to make this an HFS+ (the Mac OS extended format), and how do I do it as I can't see it anywhere on the Mac (including Disk Utility)?
