Hard drive not mounting to desktop/computer

I am setting up my AirPort Extreme 802.11 with an attached 300GB LaCie Brick hard drive with iTunes library. I can see that the Brick is recognized in the AirPort Utility > disks page, but it will not load onto my computer and I can not access it. I have the utility set to auto mount disks and have even tried to manually mount the disc, but it will not appear on the desktop. Am I missing something?
PowerBook G4 Mac OS X (10.4.6)

Hello,
I've got the same situation pretty much exactly.
I am using a Lacie porsche 250g USB disk.
Airport Disk Utility doesn't see the volume.
Airport Utility sees it just fine, but it is not showing on the desktop as it was in the past.
The AEBS was working, and the disk was being mounted properly until I began trying different configurations to allow my networked PC to also see the volume.
It seems to have started after I had set up the AEBS to assign access to the disk using accounts. I set up a couple accounts, just to see how they worked, and restarted the AEBS, but the volume did not appear. I set it back to the initial setting requiring password for disk access, and I've not managed to get it working properly again.
Any help at all would be fantastic.

External Hard Drive not mounting on Desktop

Hello,
I use a 250 gb Lacie external hard drive (firewire) for backup. For the past week, the external hard drive has mostly not been mounting on the desktop.
I don't think it's a power issue, because after turning the unit on both the light indicating power turns on and I can hear the motor operating.
As indicated on the Lacie web site, I went to disk utility in system preferences and repaired disk permissions for my Mac's hard drive volume. That doesn't seem to have made a difference.
Does anyone have any other suggestions as to what I should do?
Thank you,
Manny

External hard drive not mounting on desktop or being accessible - help!!!

Hello,
I use an Iomega 160GB external hardrive to store my iTunes and a load of video files as well as back up to but at the moment I can't get it to mount. It is visible in system profiler but I can't access any of the files. I tried verifying it and repairing it in disk utility but both of these failed. If any of you could help me out I would really appreciate it - I do have another copy of all my files on my iMac at home but i am currently studying in Spain and won't be going back till Christmas so need to get this drive up and running!

welcome to macbook forum.
try to reset PRAM to refresh your macbook port.
check the power adapter, if it comes with it, use it or check if the power adapter still good and supplied the power properly.
connect your external to other mac (you can connect to PC if it formatted as FAT32), if it succedd, back up your data and repair / reformat using that other mac.
Good Luck.

Any info is greatly appreciated; thanks!

I think you'll need two adapters as well. One to mount a 2.5" drive in a 3.5" bay, and one to convert the smaller 2.5" IDE connector to the bigger type found in desktop PCs and a separate power plug.
Here's two examples. I'm not recommending either of these products, they're just the first ones I found!

Hard Drive Not Mounting After Being Magically Changed to Read Only

I was using a firewire connected, verbatim 1tb drive as a time machine. Everything had been working fine, but I walked away from my laptop for the morning and came back this afternoon to find my hard drive changed to read only. Time machine wouldn't back up to the hard drive; so, I rebooted.
Since then, I haven't been able to get the hard drive to mount. It won't show up in Drive Utility or on the desktop. I have rebooted the hard drive, unplugged it, turned it on and off.
What should I do? How do I fix this? It has my backups and my music. I'm no amused.

I've had exactly the same trouble this morning.
I'm using a MacBook Pro with my Time Machine on a portable Hard Drive. When doing my regular back up the computer froze. I force restarted the computer and the TM drive came up as 'Read Only'.
So, I rebooted again and the drive is not mounting at all. I can see it connected through System Profiler, however the drive isn't showing up in Disk Utility.
Does anyone have any ideas? Coz I don't seem to be the only one with this issue.

I cannot get my hard drive to mount on desktop

Today I had to erase my internal (start-up) hard drive and reinstall Mountain Line (ML) and although the reinstall seems to have occurred correctly - the iMac will now start up and run properly - the icon for the internal hard drive does not appear on the desktop along with the other disk icons. When I hold the option key down during start-up the Hard Drive icon shows up among the other drives attached to my Mac - but the icon or image of the internal hard drive does not appear on the desktop. I tried to use Disk Utility to mount the disk, but even though the disk is listed and shown in the left most column of the Disk Utility window - the drive will not mount on the desktop
I seem to remember that the same thing happened when I originally installed Mountain Line on this machine - and after poking around in countless menus I found an option that when selected caused the internal hard drive to mount on the desktop just fine. But I've not been able to find that option thus far with the newest version of ML. And a search of the "Help" system was useless.
Can anyone shed some light on the resolution of this problem?
Thanks

Hard drive not showing on desktop in 10.10.3

Well this is an interesting one! After upgrading to 10.10.3 I no longer see my MAIN Hard Drive (SSD) on the Desktop. I've checked show HD's in the Finder Preferences; but it's not visibly on the Desktop nor in the Desktop folder when I open that. It shows in the sidebar and I can make an alias (it shows in the volumes "folder") but where is the actual hard drive itself? A restart did NOT help--
My 2 other internal HD's (removed the DVD Player 2 years ago and put in my old HD and partitioned it) - they show!
What is going on?
Thanks for any ideas…

GENIUS!! Super!! Wow this really worked: I found the com.app.finder.plist right where you indicated, dragged it to the desktop, (closed all other apps first) then did a restart. It was not there at first, but I went to FINDER/Preferences and checked Show HD's (which had been checked before but was NOT checked this time) and as soon as checking all my HD's showed INCLUDING THE MAIN SSD with my startup disk.
REALLY GREAT!!!!!
I did have to reset a few finder preferences -- but I learned something: I can now use TotalFinder with Tabs (just super - can connect 2 windows and more - much better than the Yosemite tabs) -- BUT NOW IT SEEMS I can have subtabs using the Yosemite tabs. Really neat - I have, for example, 4 Main TotalFinder tabs set and put about 5 subtabs under each. Those are my 20 MAIN folders that I use all the time. Now I have 2-3 other TotalFinder Tabs that I'll use for other things (so as not to mess-up my 4 MAIN tabs).
This is just a great example of my new philosophy (since 2001 when I lost a job and did this): TAKE A NEGATIVE AND TURN IT INTO A POSITIVE.
Well I could not have discovered all this, WOULD not have discovered this without this issue today and especially not without your help, keg55 and of course the assistance of everyone here today!! REALLY APPRECIATE IT!!!

2 different brand USB external hard drives not mounting- Firewire ok

Hi, first timer here so apologies in advance.
i have to different brand external hard disks and they both show up fine with a firewire connection. the trouble is that i need to use the usb connection and neither show up. (shows up in system profiler though but not disk utility.) why USB if i can use Firewire? I will be using the disk to connect to a Wii console via usb port and the Wii is not recognizing either disk either?
Any ideas on how to get one of these disks to mount by USB?
cables are fine as work with USB only hard disks.
Thanks in advance

Hello Bob,
Thanks for your reply.
Unfortunately it does not show up at all in "disk utility". But appears in System Profiler under USB. This is true of 2 different external hard drives that mount fine with the firewire cables. One is a 3.5 inch and the other is a 2.5 inch portable. The USB cable is not faulty as tested it with another USB peripheral. Now a big believer in coincidences. Am i doing something wrong?
any other thoughts?
thanks again

External Hard Drives not Mounting after Yosemite Upgrade

I've just upgraded to Yosemite, and none of my external (USB) hard drives are mounting (they don't even appear in Disk Utility).
Any ideas?

MacBook Pro 2009. 250 SD, HD 8Gb Ram.
I have had this issue for about a year...with no resolve!
Apple and the User community have not been able to solve issue.
I have had to work around it since the Oct 2013 Mavericks upgrade which “killed” (rendered unmountable) both my USB and Optical drives.
Hundreds of replies and remedies have not corrected my issue. Hundreds of replies stating that if there was a global issue it would of been fixed by Apple, not true. And dismissive replies stating that there must be a hardware issue are very discouraging.
So now, hoping to help the voiceless masses, I'm forced to share my experience.
As I stated, I have been having the issue since one of the Mavericks upgrades. The upgrade rendered externally attached drives unmountable...They are all seen in Disk Utility. They are just not mountable. Regardless of the flavor of the disk format, either Mac or PC, they are found, seen and refuse to mount. I can see them using Terminal commands, I can see them in System Report. I can reset all the memory I want...turn it off, reset, sleep, turn on, restart...NOPE...And the optical drive takes in disks but ejects them after an attempted mounting. Keep in mind, there are no physical issues with either USB or optical drives.
So now...I have had enough and need to correct the issue or buy a new equipment - starting to get into software development and need working equipment!!!
For the past month, I have been visiting the Apple store to assist in my issues...Back Story: I'm an IT Field Tech for the largest department store in the country and I have the good fortune of dropping in the Apple store anytime I want...The Geniuses booted the MB with a bootable image of Mavericks, and the USB and Optical drives WORKED fine...So, after I had stumped the Geniuses with my problems, we agreed that we would attempt to format and re-image the MacBook...Fine, do it, it's backed-up, how you ask? - Via my wireless My Book Live 3T drive, which only took 24 hours to backup, AKA Time Machine!
Great news! The re-image of Mavericks proved to work! I WAS able to mount external drives attached! How is that possible? Don't know, don't care! It just worked! So happy!
But wait! I then took the laptop home. Connected to my WiFi, to update Mavericks to the latest version...Good so far! Then it came time for a Time Machine restore, AKA Migration Assistance restore...So, I proceeded to migrate data back to my MB via wireless drive, good so far, booted in Migration Assistant, and I chose to restore everything except the network files, thinking that may be an issue...22 Hours later, the MB migrated without issue...all apps and personal files had migrated! YAY!
BUT NOW THE USB AND OPTICAL DRIVES FAILED TO MOUNT!!!
Great now what? I know, I will just re-image and start again...WAIT, I don't have a Mavericks Install Disk, no problem, I will just create a bootable USB drive with the Mavericks Install Image I downloaded onto my MB this month...NO YOU CANNOT, because you have no use of the USB drives!...And, Apple stopped making OS CDs back in 2009...Oh, and that wouldn't of done me any good, because the optical dive was unusable, anyway!
SO, back to the Apple store with my head hanging! At this point, Yosemite came out the previous Thursday, so no more Mavericks images, great! Perhaps the new OS will alleviate my nightmare!!!!...So, they re-imaged my Mac with Mavericks, drives worked again! SO, I took my MB home and attempted to download the new OS, Yosemite...which only took 2 days due to the amount of traffic on Apple's servers!...Anyway, Yosemite finally installed without out issue! Drives still worked! And so, I shutdown and restarted the system...No issues, USB and optical drives worked beautifully! Yay, Yosemite!...Fixed all my troubles!!!...Not so fast...
And so, I, again, attempted to do a Time Machine restore, via WiFi, this time it took 24 hours to restore...AND it worked! All apps and personal files transferred without issue, So happy! Put the laptop in Sleep and left it home and went to work! Came back from work, tested the system without issues. Rebooted...USB and Optical drive are NOT MOUNTABLE!
So now, what is the file that the restore keeps pushing to my MB that kills the USB and optical drives?
I would just stop restoring from a Time Machine backup, but the only way to get into the TM image is to use Migration Assistant. I cannot view the date in time of the image in TM's Star Wars time line. So, I'm forced to back up everything from the image in Migration Assistance. Not sure that it being an encrypted image has anything to do with it...
...Regardless, what is being “restored” to the MB that continues to configure the OS in such a way that makes all external drives unmountable...keep in mind, my external keyboard, hub and mouse are usable via USB.

External hard drive not mounting

external hard drive not mounting

I fixed mine by uninstalling the software that came with the harddrive such as Tuxera and reinstalled it now myharddrive works again and i did not have to delete the harddrive and reformat it.
I tried a lot like reseting the Pram And connecting other harddrives but by unstalling the original software it works all over again. I hope this works for you because i was getting pretty frustrated myself.

Hard Drives Not Mounting - Help!

Hello,
This is my first post, so please forgive me if I leave anything out....
I recently had to replace my hard drive. Got it all going, then I noticed when I went to put a music CD in, that it would not show up. I tried others with no luck....then I put in a cd with data, and it showed up on the desktop....
While trying to mess around, I made my 2 LaCie external hard drives go away! I have tried checking cables, and they come on when the computer does, they don't show up in system profiler....
Please let me know what information you might need to help me diagnose these problems....my computer has been so good to me, I want it back up and running...
Powerbook G4 Ti 667 MHz Mac OS X (10.3.9) 512 Ram

Hi, mcholley, and welcome to Apple Discussions.
I can't suggest any remedy for your optical drive not reading audio CDs but having no trouble with data CDs, except to say it's apparently a software problem, not hardware-based.
After replacing your hard drive, did you reinstall your operating system from scratch on it, or did you restore your OS from a backup you had made?
The disappearance of your external drives (are they USB or FireWire?) may be power-related. Are they externally powered, or are you powering them from the USB or FireWire bus? If they're bus-powered, are you connecting both of them at once? That won't work: together they demand more power from the bus than it can supply, and while they may spin, they won't mount. Connect only one of them at a time. Is either of them detected by Apple System Profiler when just one is connected to the Powerbook? Does it mount on the desktop then?
If you've been able to connect both drives to the Powerbook at the same time in the past, and both have mounted OK, then there's been some hardware change recently, other than your hard drive replacement, that has caused the loss of external drive detection. Is it possible that during your recent operations you've turned off one or both of the external drives, or disconnected it/them from the Powerbook, without dismounting it from the desktop first? Depending on what, if anything, the drive was doing at the time, that can make a FireWire drive unmountable and all the data on it inaccessible. In that case it may be necessary to erase and reformat the drive. I don't know whether the same is true of USB drives.
Do you have another Mac to which you can connect the drives, to see whether they show up on it? If they do, you might have to consider the possibility that the port(s) to which you've been connecting them on your Powerbook is bad.

Hard drives not mounting on xserve

I have had this dilemna for quite some time on one computer, then yesterday I went to work on another computer with a different operating system and it had the same sympton.
Both of these computers after running for a time will not show that the hard drives mounted.
One of the computers is running Leopard on a 20"iMac with 2 GB of RAM. The other computer is an xserve running xserver software Tiger 10.4.11.
If I restart the computers, then the drives will mount. I can restart the computers if I have access through ARD, if not then I have to hard crash the computers. When running programs on these computers, File--> quit is not an option for any open software packages.
On the xserve, I have used permissions repair and this did not help.
Very puzzling and not sure why this has shown up on two different Mac OS's.
Has anyone else come across anything like this?
Thanks in advance for any help.

Hi
On the 10.5 client select the Finder Menu, select Preferences. Where it says "Show these items on the Desktop" enable Connected Servers. If you're new to 10.5 this can catch you out and make it seem as if there is no connected share point.
If the option is enabled and you're still having the problem double-check network settings first. What you could try for both affected clients is create a new admin user. Log in with it and see if the problem goes away.
If it does then you know its at least one or more corrupted/damaged preference or .plist in the Users Home Library Preferences folder.

Serial ATA internal drive not mounting to desktop

I installed a serial ATA Seagate Barracuda 7200.9 Hard Drive - 300GB in my G4 MDD. I had previously installed a 120GB Seagate SATA drive into this same computer and it was immediately mounted onto the desktop after rebooting. However, that didn't happen this time. The drive installed easily but it is not mounting on the desktop. It is attached to the same PCI card as the other SATA drive. When I open disk utility, it does not show up as a SATA drive but as an ATA drive and it says it is not S.M.A.R.T compatible. What have I done wrong in connecting this drive???? Any suggestions would be most helpful
Dual 1.42 Ghz PowerPC G4 Mac OS X (10.3.9) 2 GB DDR SDRAM

Hi
If I remember correctly Seagate initially shipped the 7200.9 drives with something called Spread Spectrum Clocking (SSC) enabled. This isn't supported by most PCI SATA cards (or inbuilt SATA controllers come to that) and the drive won't work. I think Seagate made a utility available to switch if off, but it was Windows only and the drive had to be installed in a PC first.

Hard Drive Not Mounting NTFS Tried MacFuse and NTFS-3G

Issue:
Mac OS X Tiger
- External HD NTFS Formatted (Win XP)
- Does not mount, but shows in Disk Utility (running on USB2.0)
Ran Disk Utility's Verify Disk:
Invalid B-tree node size
The volume needs to be repaired.
Error: The underlying task reported failure on exit
1HFS volume checked
Volume needs repair
Repair Disk:
same errors above
but under HFS volume check shows 1 volume could not be repaired because of an error
I've tried installing Macfuse and NTFS-3G and FinkCommander. I've tried running terminal commands offered on various sites.
I don't have Bootcamp.
I believe this hard drive was connected to my pc (win xp) when it may have crashed on me. I think its a recovery issue because I run a 4 bay usb hd box that probably wasnt plugged in when this happened, and those hard drives can be seen my this mac. The crashed computer's hard drive and this external hard drive are the only ones not being read. Can somebody help me? Thanks.
PS- I ran a demo of Boomerang and showed all my files on this external hard drive. It was all under the Regular tab, not the Lost tab.
I have techtool pro as well. I just got it yesterday,and I'm not sure if it's supposed to fix this stuff.
Do I need one of the recovery programs out there like Diskwarrior, DataRescue, Boomerang, etc etc?

Is it possible that your hard drive is full enough that there was not enough space on it to complete the reinstall of OS X 10.4?
You may have partial installs of the OS on the hard drive which have totally filled the drive. This is not a certainty, just a possibility, but it could explain why there is no error report on the drive.
Do you have access to another Mac with FireWire? If so, you can try to use FireWire Target Disk Mode with your iBook as the Target Disk to see if you can retrieve your data to the other Mac's hard drive.
Instructions on recovering from the flashing question mark folder can be found in this Apple Knowledge Base article:

Hard drives not mounting properly

Lately my MacBook Pro Core Duo 2.4 GHz, OS X 10.5.8 is having trouble mounting hard drives. If I start from my external drive the internal drive may not mount on the desktop or mounting may take a minute or two. Disk Utility will see it but the Mount option is grayed out and I shouldn't have to use that anyway. Similarly, if I start off the iternal drive the external drive may not mount, or mounting may be delayed by a minute or two.
Also, drives appear inconsistently in Startup Disk Prefs or the Finder Window Sidebar. They may not show at all or be delayed in showing up.
First Aid reports no problems with the drives, I have a fresh install of 10.5.8 on my internal drive, permissions have been repaired, directory rebuilt with Disk Warrior 4.1 and the drive optimized with Tech Tool Pro 6.
This and the fact that Boot Camp will not launch are making things difficult for me.
Any suggestions? Thanks.

I have that when using an iMac at work - my external is an old FW400 Formac drive.
Tracked it down to when VMWare Fusion is running - it seems to arbitrarily 'seize' new devices, and then doesn't know what to make of them because they're HFS.
If I connect it either pre-startup, or before VMWare starts there's no problem.
Do you have something running which is grabbing/affecting your Firewire bus - check the logs in Console.
