Help Getting an External Hard Drive to Mount.

I cannot get my LaCie 120 external drive (connected via firewire 400) to mount on my Mac Pro. It worked fine a couple of days ago. I ejected it and proceeded to connect a second firewire 400 drive and when I tried to reconnect the LaCie, the computer didn't see it. I tried the disk utility and there is nothing for me to select so I can't repair, mount, or format it. It's just not there. I've tried everything I could find information for, new cables, unplugging the computer to get the buses to reset, etc.
What I find odd is that when I plug the LaCie into my macbook it loads fine and all the information is present. I could just do a work around and transfer all the info from the LaCie to the new drive using the macbook, but it's a large amount of video, and it would take a very long time.
If anyone has any info or other ideas about getting my LaCie to mount it would be greatly appreciated.

I have had a problem on my Mac mini with USB external hard drives. Did you try plugging it into a different port? I find I would need to reboot to get the drive to work again. I fixed it with a USB hub. Works fine now. Probably a different problem, but just making sure.

How do I get an external hard drive to mount?

I have two Maxtor One Touch 4 Plus External Hard Drives. One works the other doesn't. The one that works is over a year old and has been a trusty loyal aid. The one that doesn't is only a couple of weeks old. It worked fine initially. Now no icon appears and its volumes won't mount. I have switched both HD's between a MacBook Pro and an iMac with the same results. I've also switched between USB and Firewire cables. Same again.
I have a fair idea what went wrong.
The adapter for the new faulty HD was dislodged a little from the power socket. A small electrical crackle was heard, nothing to serious, but obviously enough to create this problem. The power jacks here in this part of the world are not often the best and snuggest of fits.
I have visited the Seagate/Maxtor "support" sites and come away with nothing other than switching on and off, etc... very elementary.
Any suggestions as to how I can get this dodgy piece of hardware to get over itself and get operational again?
Thanking you in advance.

Do you hear the drive spin up?
You may want to contact the manufacturer and ask for a replacement power adapter/cord and see if that helps.
Personally, I think there has been some damage to the circuitry inside the enclosure, which really can't be repaired.

Tiger randomly stopped allowing my External Hard drive to mount and...

Hello, I have been using an External Hard Drive (1 terabyte Seagate, new) for a couple months if not a year by now for saving movies, and all of my iTunes on it. Its been working wonderfully. However it recently stopped being able to mount citing invalid hard drive and gives me the options of either eject, ignore, or initialize. Im not sure what to do. And also my computer has been acting funny every since the day it started. I will walk you through it step by step.
July 6th I was surfing the web and unfortunetly clicked on a link that aparently contained a trojan. Or atleast thats what my Antivirus notified me of. I had downloaded the trojan some how without a pop up or anything telling me I was downloading anything. (using safari) So i ran a virus scan and saw one virus was in my system and that it couldnt be deleted or repaired by my antivirus program, Im working on getting rid of that but at the time I had my Seagate 1 terabyte external hard drive attached via fire wire to my Macbook. It was working then.
Later that day I unplugged my hard drive and took my laptop around a little bit, nothing unusual. Then when i came back later that night I tried plugging in my hard drive and a pop up stated that the hard drive was unable to mount and I could either eject, ignore, or initilize. I tried may different routes, restarting, letting it all rest, etc. And in Disk Utility i try to verify the disc and it says its unable to and needs repairs. So I try repairing the disc and it says unable to due to an error.
Then yesterday I went to my applications and noticed none of my applications are there anymore. These applications were saved on the internal hard drive so it was very odd to me. However i can still use spotlight to find and open my apps.
My question is, What can I do to allow my external hard drive to mount? I dont figure it is the trojan on my system but could it be? If so how would I fix it? Im mostly worried about getting the data off the external hard drive then I can reformat it. Or if theres a way to just get it back to normal without reformatting Id love to hear it. As for the applications missing and the trojan on my internal hard drive I can fix that, at the very least Ill just reboot my system with my original OS Disc and just start fresh, its about time anyways.
But please. If anyone has ever had their external hard drive just stop mounting and figured out what to do I would be ever so grateful to hear how you did so. The hard drive itself isnt damaged, its not making any unusual sounds. Whenever i plug it into the computer it acts like normal (turning on and what not) until the computer tells me it cannot mount then nothing happens. Ive looked online and it seems to be a software issue.
If its any help I was downloading a torrent (.avi, no viruses) at the time. I know sometimes if one file on the hard drive becomes corrupt the whole thing becomes unusable. Regardless I would appreciate it if anyone knows a way to at the very least retreive the files on the drive, but preferably know how to just get it back to normal. If i could get it to force mount (via terminal or something) I know which file would possibly be the corrupt one or something so I could work with it.

Thanks for posting back with the pics of the messages from your computer. Disk Utility reports "Underlying task reported failure" when repairing a volume is a directory error which cannot be repaired by Disk Utility. Unfortunately, Disk Warrior may not be able to replace the rebuilt directory, either. Tech Tool Pro has a better chance of repairing it, although this particular directory issue can be stubborn, and is often rooted in a hardware issue. Your surest bet is to backup/clone the information on the HDD using a utility like SuperDuper or Carbon Copy Cloner, completely reformat and erase the HDD (directions below), then restore data from backup.
Formatting, Partitioning Erasing an External HDD
• Connect external HDD to computer
• Turn on external HDD
• Start up computer and log in
• Go to Applications > Utilities > Disk Utility and launch DU.
• Select your HDD (manufacturer ID) in left side bar.
• Select Partition tab in main panel.
• Click on Options button
• Select Apple Partition Map (PPC Macs) or GUID Partition Table (Intel Macs)
• Click OK
• Select number of partitions in pull-down menu above Volume diagram.
For more partitions than one, after you have selected the number of partitions adjust the size of the partition by selecting the top partition and typing in the size; then move down if more adjustments need to be made.
(See Dr. Smoke’s FAQ Backup and Recovery for tips on partitioning external HDD)
• Type in name in Name field (usually Macintosh HD)
• Select Volume Format as Mac OS Extended (Journaled)
• Click Partition button at bottom of panel.
• Select Erase tab
• Select the sub-volume (indented) under Manufacturer ID
• Check to be sure your Volume Name and Volume Format are correct.
• Click Erase button
• Repeat above procedure to erase each partition
• Quit Disk Utility.

I have iMovie 09. I just erased my external hard drive, but it is still formatted for the mac. However, iMovie will not recognize the hard drive. It shows the only hard drive available is the computers. How do I get the external hard drive to show up?

In Finder's Menu, select Go menu>Go to Folder, and go to "/volumes". (no quotes)
Volumes is where an alias to your hard drive ("/" at boot) is placed at startup, and where all the "mount points" for auxiliary drives are created for you to access them. This folder is normally hidden from view.
Drives with an extra 1 on the end have a side-effect of mounting a drive with the same name as the system already think exists. Try trashing the duplicates with a 1 or 2 if there are no real files in them, and reboot.

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

Please help... External Hard Drive not mounting

Hello, Please help me if you can:
I have all of my data backed up onto a Seagate External Hard Drive, purchased just a few months ago. I just got a new laptop (MacBook Air) and need to get my data off of my hard drive, but it isn't showing up on my Desktop or Finder. It shows up in Disk Utility, but when I ask it to "repair" it says:
"Invalid B-tree node size
The volume could not be verified completely.
Volume repair complete.Updating boot support partitions for the volume as required.Error: Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files."
The problem started after I added some data to it - I accidentally unplugged the Drive without Ejecting first. The next time I plugged it in it allowed me to view my files but not add anything else to the Drive, and now when I plug it in it doesn't even appear. I am running Lion.
I would be happy to back up the files as it says, but as it doesn't show up anywhere I can't find the files to access. Can anyone help me find a way to get the files off of the disk, or fix the disk so that it is readable?

Hi, Brian, and welcome to the Discussions!
You might perhaps launch System Profiler (from Applications/Utilities) and see if the device is listed there under the FireWire heading in Hardware Overview.
Can you hear the LaCie spin up when powered on?
You might download the free trial version of Data Rescue II and launch it to see if it recognizes the drive. This software often does when DW or Disk Utility won't. If it does, run a scan with it to see if the data on the volume is viewable.
You can test the FireWire port with another Firewire device, or by hooking up to another Mac via a FW cable and trying to boot into FW Target Disk Mode. Visibly check the port at the Mac end first to insure that there are no bent pins at the connector (so you won't damage another device).
You can try resetting a "dead" FireWire port by shutting down, unplugging the external FireWire devices, and disconnecting the Mac's power cord for thirty minutes or so. Before doing this, run Disk Utility's Repair Permissions process on the startup volume first, to see if that corrects it.

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.

How do I setup an external hard drive to mount at boot (without any login action) in Mavericks?

First the Details:
MacBook Pro, Retina, 15-inch, Late 2013
OS X Mavericks 10.9.5
USB 3.0 External Hard drive
I am currently using an external drive for my user storage. Right now I log in with a separate User account to mount the drive, log off, and then log in with my user. I am trying to remove the extra steps so I can boot my Mac and log right in. I have not found any method that pertains specifically to Mavericks, and all of the methods I have tried for older OS versions do not seem to work properly.
Thank you for your help.

How is the EHD formatted? It is USB powered? If it's formatted OS X Extended (journaled) with ownership set to be ignored and connected to a USB port it should mount as soon as the MBP is booted up and the EHD is spun up. It should be accessible to all accounts on the Mac.
Do you have additional software that came with the drive that you've installed? What make and model drive is it?

Problems getting an external hard drive to work on the new Airport Extreme

I have spent hours trying to get my 320GB external hard drive to work with the new airport extreme 802.11N. I have spent hours pouring over all of the posts here discussing possible solutions, all of which have not worked. This morning, however, I gave it another try and FINALLY, I have it working. I tried something simple. Here it is:
Using the Apple Disk Utility Program, I formated my drive using the MS-DOS mode, called my Hard drive "ItunesHD". It took about 20 minutes to complete (i'm assuming because of the size of the drive). I then unplugged the router and hard drive, turned on the hard drive, then the router. After my macbook pro reconnected, I clicked on the iDisk utility icon in my menu bar, provided my password and FINALLY saw the network drive icon on my desktop!!! It seems that formatting my drive using MS-DOS compatibility mode finally worked for me. I'm not saying this will work for anyone else who is having this problem, but you can at least try it. I tried all of the MAC formatting options and have had no luck.
What I would like to know now is (..if anyone has these answers, please let me know):
1. What is the maximum SINGLE drive capacity that this router will understand...500GB, 1TB, 2TB? I would like to get the biggest bang for my buck.
2. Keeping #1 one in mind, I purchased an Apple TV (still waiting on it to arrive) and I would like to know if it will read multiple hard drives connected to the Airport Extreme router (...say (2) 500GB hard drives). I know you can have multiple libraries in iTunes (which to me is a cheesy solutions, there should be an option in the preferences that would allow you to save your music in one place and your movies in another). Anybody have any idea on this one?
I basically want to rip all of my dvd movies on a big hard drive connected to my airport extreme to use with my AppleTV , so I just need to find out about the maximum size and hooking up more than one hard drive and getting the AppleTV to recognize them all.

MacBook Pro Core Duo Mac OS X (10.4.8)

Sorry you had so much trouble hooking up a hard drive to the base station. I've done some experimenting with the feature and this is what I've found out.
You can use either the native Mac format, Mac OS Extended, or the Microsoft format known as FAT. Apple calls FAT, MS-DOS File System in Disk Utility.
If you use Mac OS Extended, the Macs on the network will be able to connect to the drive using the native AFP (Apple File Protocol) or the Microsoft native SMB (Server Message Block) protocol. PCs will only use the SMB protocol of course.
If you use MS-DOS File System both the Macs and the PCs will only use SMB to connect to the drive over the network.
Basically I've found everything works as expected with regard to volumes connected to a network.
One thing I don't have installed is the iDisk Utility. I'm wondering if it may be the cause of the problems you were having. But reading through your post it may also be the difference between expected behaviour and the proper procedure for discovering and mounting network volumes. Let me explain.
You only mention having trouble getting the drive to show up on your Desktop, you didn't describe how you went about discovering the network drive. It isn't just suppose to show up on your desktop when you plug it in to the Extreme base station. It doesn't work like the iDisk or disks connected directly to your computer using USB/Firewire.
Normally with network drives you're suppose to either browse for them using the Network icon in the Finder or using the Connect to Server command in the Finder's Go menu, you would type the address in directly for the network volume you want to mount. Try it and see what happens.
Now to answer your other questions.
I don't have a volume large enough to hit any limits the base station may have but I did read a post about someone who said they had a 1.5 TB volume connected and could only see 1 TB of it. They were forced to partition the drive to see all available space and of course the volumes showed up as two separate drives. One thing wasn't made clear though. They didn't say what volume format they were using to format the drive, Mac OS Extended or MS-DOS.
Everything having to do with the AppleTV is just speculation at this point since no one has one yet but from what has been demonstrated so far, AppleTV relies on iTunes. In other words, it won't pull data from network volumes on its own, a computer running iTunes needs to feed it.

WD Elements External Hard Drive not mounting

My external hard drive is not mounting it is connected by via USB connected directly to my Macbook. When I connect it error "The disk you inserted is not redable by this computer". I can see it on Disk Utility however all options are grayed out. I also tried connecting it to my sister's windows machine same thing not mounting. I've tried this suggestion http://support.apple.com/kb/TS2176 but I got an error "Error: -69877: Couldn't open device".
By the way it's a self powered 2.2TB WD Elements
Badly needed help!

I had the same info (with a WD essentials encolusre where I just replaced a 750 with a 2TB), but after closing both DiskDrill and Disk utility, the terminal worked. So have a look if there are any other disk monitorings on.
good luck

External hard drive NOT mounting to mac

I have never had problems with my external hard drive (I just bought it a few months ago), but suddenly it is not mounting on the iMacs at my work or my Macbook pro at home. The drive does NOT show up in Disc Utility, but when the drive is connected via USB, the light on the drive comes on and it is clearly operating. It will not mount on any mac product all of a sudden. I have no idea why this is happening someone PLEASE HELP thanks

you have a MacBook Pro, we are Mac Pro users.
It uses bus-power? has its own power brick?
Formatted for Mac (HFS)? Used on PC Windows and Mac?
Do you have it backed up?
Has there been an inadvertent outage or crash?

Lacie firewire 800 external hard drive not mounting in mac os 10.4.8

I have a pm g5 Dual 2ghz system ,i have connected an firewire 800 lacie 1tb external hard drive to the system,now the problem is it is not mounting on the desktop shows in the diskutility repaired the disk say's disk volume ok any way to mount the external hd on the desktop

Hi Veena, Welcome to Apple Discussions.
And you've tried choosing the volume and pressing the "Mount " icon on the tool bar of Disk Utility?
Have you shut down your Mac and disconnected your firewire cable from both ends and let it sit about ten minutes then reconnect and try. Also, it is important to disconnect the AC power to your Mac, this helps to reset the FireWire port(s).
Do you have TTP or DW, both of which you could use to try to mount it.
It is also possible that you have a bad cable or a bad port, do other FW devices work?

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..
http://www.iomega.com/support/manuals/800mseries/trblshoot_conf.html
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

How to get an external hard drive to work on my iBook?

I have an old iBook G4, and I recently bought a newer macbook. I want to transfer all of my stuff from my old computer to my new one, but there's a problem. I have a Toshiba external hard drive that I bought a few years ago to use on my mom's iMac. It mounts on her computer, but for some reason, it won't mount or do anything on my iBook. Whenever I hook the hard drive into one of my iBook's usb ports, nothing happens. I have no clue what to do to get it to work. Does anyone have any ideas?

You can find the instructions here:
https://discussions.apple.com/message/15189318#15189318
Because Migration Assistant isn't the ideal way to migrate from PowerPC to Intel Macs, using Target Disk Mode, copying the critical contents to CD and DVD, an external hard drive, or networking will work better when moving from PowerPC to Intel Macs. The initial section below discusses Target Disk Mode. It is then followed by a section which discusses networking with Macs that lack Firewire.
If both computers support the use of Firewire then you can use the following instructions:
1. Repair the hard drive and permissions using Disk Utility.
2. Backup your data. This is vitally important in case you make a mistake or there's some other problem.
3. Connect a Firewire cable between your old Mac and your new Intel Mac.
4. Startup your old Mac in Target Disk Mode.
5. Startup your new Mac for the first time, go through the setup and registration screens, but do NOT migrate data over. Get to your desktop on the new Mac without migrating any new data over.
Copy the following items from your old Mac to the new Mac:
In your /Home/ folder: Documents, Movies, Music, Pictures, and Sites folders.
In your /Home/Library/ folder:
/Home/Library/Application Support/AddressBook (copy the whole folder) /Home/Library/Application Support/iCal (copy the whole folder)
Also in /Home/Library/Application Support (copy whatever else you need including folders for any third-party applications)
/Home/Library/Keychains (copy the whole folder) /Home/Library/Mail (copy the whole folder) /Home/Library/Preferences/ (copy the whole folder) /Home /Library/Calendars (copy the whole folder) /Home /Library/iTunes (copy the whole folder) /Home /Library/Safari (copy the whole folder)

/Home/Library/Cookies/Cookies.plist /Home/Library/Application Support/WebFoundation/HTTPCookies.plist
For Entourage users:
Entourage is in /Home/Documents/Microsoft User Data Also in /Home/Library/Preferences/Microsoft.
Credit goes to Macjack for this information.
If you need to transfer data for other applications please ask the vendor or ask in the Discussions where specific applications store their data.
5. Once you have transferred what you need restart the new Mac and test to make sure the contents are there for each of the applications.

You need to read the entire User Tip for warnings about what may be incompatible, but that is the gist of how to get things over. (To start up your iBook in FireWire Target Disk Mode, hold down the t key during startup.)

External Hard Drive not Mounting any more

Hi all,
I have noticed since couple of kernel updates, my external hard drive - plugged via USB doesn't get mounted any more. To access the drive I need to reboot the computer with the hard drive switch on.
See below for the dmesg output, regular usb keys get mounted normally, I have check autofs set up and it seems fine compare to the wiki,

Yes I have checked System Settings -> Removable Devices - but there is no option for an external hard drive.
And yes it is a ntfs drive, but as I said it worked before couples of updates ago, and just to be sure I checked ntfs-3g - it is installed.
Oh, and I should have said, checking /dev/by-label the drive appear there once turn on, but doesn't get mounted, I use to have a line in the fstab file, but I removed it because it tried to mount it during booting process, and it work anyway.
Any other advice?
