External Lacie hard Drive would not Mount on my imac

HI all,
I have had this Hard Drive for a few years now, worked great, no issues at all. Even after upgrading to 10.8 it continued to work.
A few days ago my cleaning lady moved the computer and disconected the Lacie drive (connected via Firewire) and since then I am not able to mount it again.
I see it on my Disk Utility but when I press "mount" I get an error messege "the disc can not be mounted, try First aid" but non of the buttons on First Aid work.
So far I tried re-settign the SMC, of course shutting down and starting back up numerus times but nothing.
I even tried working through Terminal, it can see the drive and its partition and when I looked online I saw a few commends to try and mount it, but nothing worked so far.
Here is what i wrote and got in terminal:

Details on my system:
its 10.8.2, iMac Intel core duo 2
The Drive is connected by Firewire
The drive is clearly there, it's working, I hear and feel it working (spining) but can't mount it.
What can I do in order to mount it and get my data of of it?
this is extermely important as my itunes library is there. PLEASE HELP SOON!
Thanks!

Update:
so, I shelled out the $100 to get Disk Warrior, and got the following messege:
Directory cannot be rebuilt, the file system is unspported
This disk is not a macintosh Disk
and further down the list it said: File system: Windows/PC
All of this is of course distressing as this has been a Mac disk for several years now, not to mention the $100 gone in the wind.
what should I do now?
I have Parallels, would that help? is there a way of mounting the disk on there?
Should I try connecting it to a PC?
Please Help me!!

HELP - External USB Hard Drive Will Not Mount

Ok, I've read through MANY other external HD mounting problems but can't find anything that helps me with my specific problem. Here goes...
I have all of my graphic/music files on the HD of my Mac. I want to copy these files to a drive so that I can clean it off and sell it. I will be transferring the files to a PC.
I purchased a USB external HD from Best Buy four months ago. I plugged it in and it asked me to reformat the drive as Macintosh. I took it back and had them reformat the drive as FAT32 so that I could use it on both systems. I had this done twice because it didn't work the first time. Well, it didn't work the second time either but they tested it on their Macs and it worked so I think it's a problem with my Mac.
The drive is recognized in both the System Profiler and the Disk Utility. When I try to mount it in the Disk Utility, nothing happens and it goes back to "Select a disk or volume".
I would like to get this problem fixed without spending any more money on it. I've contacted Mac techs and they usually charge $100/hour and can't guarantee how long it would take to fix. That, and I don't know anyone I trust with my precious data.
I'm beyond frustrated with this as I have been dealing with it for over six months now. I have tried unplugging and replugging but nothing seems to work. I've tried all USB ports (keyboard, monitor, tower) and various different power outlets (wall, power strip, etc...). The data is irrecplaceable and I'm nervous that it just sits on the computer without being backed up. If anyone has any ideas for me to try, please let me know. I am at my wits end.
Also, now it seems that Apple System Profiler "unexpectedly quits" when I try to open it. Any ideas???
Thank you

Here is a USB faq. Hope it helps!
Try using Disk Utility to do a Disk Repair, as shown in this link, while booted up on your install disk for your unepectedly quit issue.
You could have some directory corruption. Let us know what errors Disk Utility reports and if DU was able to repair them.
Try the repair first. if no luck try things in this Unexpectedly Quit link.
Cheers! DALE

External Hard Drive will not mount after upgrading to Yosemite

After upgrading to Yosemite, my external 3TB hard drive will not mount... can't see in Finder, but does appear in Disk Utility. Follow steps to Repair disk, but get a message that D.U. cannot repair disk.

External Hard Drive does not mount

My 2TB external hard drive does not mount and I cannot get it to. Have tried turning the hard drive off and then back on. No response. Any thoughts as to how I can get it to be recognized?

You can try doing a SMC reset, if it doesn't work the first time it's totally OK to reset the SMC several times.
SMC RESET
Shut down the computer.
Unplug the computer's power cord and all peripherals.
Press and hold the power button for 5 seconds.
Release the power button.
Attach the computers power cable.
Press the power button to turn on the computer.
PRAM RESET
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

Lacie Hard Drives won't mount

My two Lacie hard drives won't mount on my G5 running Tiger. They were fine on my G4 iMac running Panther. I've tried using the Lacie Update Tool but the drives aren't recognised. I've tested the firewire cables on another drive that works and they're fine, so it's not cables.
Both drives power up okay and whir into action, but just aren't talking to the G5.

Any ideas much appreciated.

This happened to me with a LaCie external drive as well.
The problem is that LaCie formats the drives as PC-based
and not Mac Extended, so unless you reformatted the
drives to Mac when you started using them, your access
to them on any Mac may result in a failure to mount.
Once that happens retrieval of data is made more difficult
because of this formatting incongruity.
There is no way you can get the data once your G4 quits
mounting them. If you can get the data off of the drives,
back it up and then reformat the drives using Mac's Disc
Utility. Then you can reload the data and I suspect all of
your Macs will then mount the drives via Firewire.
Good Luck!

External hard drive is not mounting via hub

Hi mates,
I bought LaCie D2 Quadra external hard drive and when I connected it to LaCie Huby firewire port it would not mount at all, but when I connected the hard drive straight to my MacBooks firewire port it mounted nicely.
what could be the problem that its not mounting with the hub?

Just tested with USB and it works.
oh.. just remembered that I sync my iPod through one of the Hubys fw ports, so I guess that ports are OK.
Maybe I have a faulty fw cable?

External Hard drive will not mount on desktop

I have a 17" Powerbook G4 that has replaced a broken iBook G4. I've been using a Western Digital MyBook Pro Edition as a secondary drive for my multimedia as well as my iTunes Library. It worked fine on the old iBook.
When I plug it into the Powerbook, using either USB2 or Firewire 800, it will not mount to the desktop. It DOES however appear in the System Profiler as "External HD Button and Lights". The drive is formatted for FAT32 and works fine on my Windows XP desktop machine, so I know the drive functions mechanically. A different hard drive, a Maxtor mounts to the desktop fine using USB2, so it isn't a bus issue.
This is driving me nuts. I LOVE this computer, but I have WAY more invested in music than the cost of the computer.
Thanks in advance.

It took a while to figure it out but apparently there was a conflict with bluetooth. I disabled it and all is well.

LaCie Hard Drive No Longer Mounts on iBook G4

Hello,
My LaCie 600 GB Hard drive will no longer mount onto my iBook G4. I had this problem about 6 months ago. It was solved by reformatting my whole computer through the installation disks that came with my computer. After I reformatted it, the hard drive was immediately recognized. I don't want to go that route again because I have a lot of programs on there that would take forever to reinstall. I have all of my important info backed up, just not the programs itself.
I've tried running:
Macaroni
Utility Disk
Data Rescue II
And neither of these came up with any "diagnosis" on why my hard drive won't mount. I check my cables through plugging my hard drive in other computers, and it works fine. I think it has to do with my hardware on my iBook G4.
When I plug it into my usb port, the blue light on my hard drive turns on, and I can hear the inside spinning. It just doesn't pop up onto my desktop. It doesn't show up in disk utility either.
Any ideas on what I can do?
-Kristen

I would contact the folks at LaCie for their feedback.

Hard drive will not mount shows up in Disk Utility

I have an external drive with a bootable OS X 10.6.8. I was in a transition between building up a SSD swapped drive. The SSD is installed in the CPU box but I have my old installation running from an external.
I have several external hard drives. They are all Firewire. Some have USB 3.0 and or eSATA options but my MacMini only talks to Firewire and USB 2.0.
I understand that you daisy chain Firewire drives and turn them on and off in sequence as they fall from the CPU box/case.
Firewire is a power source. I run the external with the OS using an AC adapter but one Firewire drive is powered through Firewire.
I have had as many as 4 external drives running along with the internal drive without a glitch while I was reorganizing files.
Today I booted off the external drive. It was running fine. I turned on one Firewire drive (the one that runs on Firewire power). That drive stumbled. I recognized the sound when there is an interruption in power. This cause the external boot drive to stall. I had to force a reboot.
Now the external boot drive will not boot up. It does not mount but Disk Utility sees it. The drive itself is bright and clear in Disk Utility but the partition (single) is faded out. I can run Verify and repair in DU. DU says it doesn't see anything to repair. It will not mount on its own or when I click the Mount button in DU. It does not produce an icon on the Desktop (because it is not mounting).
I also have SpeedTools. But although it sees the drive I cannot do anything with it. None of its tools run more than a spli second before they fail.
This drive has USB 3.0 and I see everything through USB that I see through Firewire. Connecting the other way did not get around the problem.
Of course I will buy an AC adapter for every external drive and never run them using Firewire again but the horse is out of the barn.
I have the original installation disks and could run the Archive and Install option but it would require physically swapping drives with the internal. I'd like to avoid it if possible. It is a MacMini and tedious.
Any suggestions?

I took the problematic hard drive and installed it in my Mac Mini so I could attempt a Safe Boot and then Archive and Install if necessary.
Safe Mode didn't work. The drive produced the circle with a slash symbol.
I reset the PRAM which was part of a list of steps to work through I found created by Apple Support.
I was able to boot up to Verbose Mode and view the text of the boot process. I wrote it all down. I can answer questions about the content better than typing it all out exactly. It includes, "...journal magic is bad..." "...failed to open..." and ends with "...cannot mount root, errno = 19"
I attempted Archive and Install however when it went to show what target drives were available it was a blank box and all buttons were grayed out.
I rebooted and opened Disk Utility from the DVD. The drive appeared the same with the top main line bright and the partitioned volume faded. Still was unable to mount. I ran Verify and this time a red line of text appeared "Invalid content in Journal" and at the end I ran Repair. When running I could read line by line and at one point it showed "checking volume information" then the following line "Repairing volume" the following line "Rechecking volume" more line of checking then it ended with "The volume was repaired successfully."
It still would not mount. I ran Verify again and again said "Invalid content in Journal" and this time it stopped midway saying "The volume was found corrupt and needs to be repaired. Error: This disk needs to be repaired. Click Repair Disk."
I clicked Repair and it ended with The vol. was repaired successfully."
Still unable to mount I began repeating Repair over and over. Each time it found something to repair and ended with a success message. After several more Repairs I tried Verify and it stopped midway saying to Repair the disk.
Question: Does running Repair multiple times continue to correct bits and pieces little by little or is this a generic message and we should treat it as a problem Disk Utility cannot pinpoint and is just beating its head against the wall?
The step by step instructions I downloaded mentioned running Repair more than once but it did not say that running it 20 times would erode some problems and eventually lead to a fully repaired disk (if the problem was something DU could take care of in the first place). At this point I have run Repair about 20 times total with a series of 10 back to back skipping Verify. I keep seeing the lines about invalid content in a journal and that it repaired something successfully. Yet I still cannot mount the disk.

Internal hard drive does not mount in disk utility

My internal hard drive no longer mounts in Disk Utility. It is grayed out. I have extraordinarily frequent spinning beach ball/freezes, in Safari or Apple Mail. The most recent symptom: upon rebooting or just starting up, I see flashing black on the display. This has been occuring for more than six months. Of course, I have made total and frequent backup's. I bought new RAM, but have not yet installed it, and I susect this might help. I have done repeted troubleshooting many times each: Apple's Disk Doctor, Repaired Permissions, Reinstalled the Mac OS, safe boot, Alsoft's Disk Warrior, Apple's longer Harware Test, etc. I have worked as a new user, too. All tests done report that all is well. What od you thnk the problem is? Must I drive 1.5 hrs. each way to the Genius Bar at my nearest Apple Store? Might I try to erase the hard drive as a fix? I hate to do this, only as a last resort, as it is so time-consuming. Should I just update my Mac OS? Please advise, out there, if anyone can offer any advice, I would be greatly appreciative.

The list of issues you posted probably would not get shorter if you attempt to 'upgrade them' away, as usually that kind of effort is not effective yet may expose more of the same problems while not necessarily revealing the original weakness. Another OS X installed over a set of problems seldom helps.
How full is the hard disk drive? If it is too full, or has been very busy in use several years, it may be time to replace the HDD and perhaps put a larger capacity one in the computer. And if the main computer hardware checks out OK (tested under a variety of duration and stress tests) then also consider a RAM upgrade if the device is not already at the maximum capacity.
When was the last time the hard disk drive was devoid of content, maybe wiped -- erased and reformatted by a third party disk utility or have a utility overwrite the entire HDD with zeros? This used to be a common tech service in the course of a major effort to restore a Mac. Or Defragment?
If you can do the latter, this could help resolve bad sectors and remove old data or corruption on the hard drive. Or get a new HDD and before committing a new OS X install & apps to it (or a re-clone of a complete backup) test the drive and be sure it is ready for use. Not all new drives are perfectly ready; some need to get exercise first.
I'd bet on a new hard disk drive of larger capacity (also note spin RPM rate and data speeds) and a full RAM upgrade.
If you have a backup clone on an external hard disk drive (in a boot-capable enclosure) you could really go to town and before you erase the main/only hard drive, make a backup clone and test its ability to boot the Mac. Or put the old drive and content in a suitable boot capable enclosure of the kind with its own power supply, and deal with it later.
Then consider a later version OS X -- whatever most recent version that model can support... {edited}
Good luck & happy computing!

USB2 Hard Drives will not mount under 10.4.11

I have a 2.33 GHz Intel Core 2 Duo MBP, with 2 GB of RAM. Using the 10.4.9 OS and earlier, I had no problems at all mounting and using an external USB hard drive that I use at both work and home. When I updated to 10.4.10, the drive stopped mounting, so I took it and the computer in to the Genius Bar. The only solution he could think of was to roll my OS back to 10.4.9, which worked immediately. The drive started booting again without any problems.
I took my MBP in for an unrelated issue and the Genius at the Genius Bar (same guy who rolled it back, I think) suggested I upgrade and that the USB mounting issue wasn't a problem any more. I upgraded to 10.4.11 and once again, my USB hard drive won't mount.
I have no problems getting it to mount on my XP machine at work and our G4 Mac Mini at home has no trouble with the hard drive either, so I'm positive the drive is fine. The problem is with the OS update to 10.4.11.
My iPod mounts just fine (which is also USB2) and my thumb drives seem to work just fine, but I do have an older drive that has stopped working. Like my external HD, it mounts just fine on other computers.
Does anyone have a fix? The Genius I spoke with when this problem first started suggested I ditch the drive and get a Firewire one, which is a nice thought, but I shouldn't have to replace hardware that works just fine, because something in the OS updates isn't working. Do I have to roll back to 10.4.9 again?
I have to say, this is a bit frustrating, as I already dealt with the problem, was assured it was fixed, and then ran into it again.
Robb

I recently had a similar issue (different conditions, same issue) and here is what I posted, maybe it can help you:
http://discussions.apple.com/thread.jspa?threadID=1638087&tstart=0
I didn't mention another possible solution mentioned somewhere else: replace certain kernel extensions in your 10.4.10 or 11 installation with those present in 10.4.9: "IOHIDFamily.kext", "IOUSBFamily.kext" and "IOUSBMassStorageClass.kext" (using Pacifist).
An update to this post: now my external disk doesn't mount again. I'm pretty sure the disk is OK, as it mounts in different machines and it works fine thru the USB 1 interface (keyboard hub).
I tried the solution's point two (deleting kext caches) and it worked pretty fine... Until the next restart. Doesn't work anymore. USB Prober (point three) no go. I think I'll try replacing the kernel extensions. It was reported as successful, but I'm currently running 10.5.4 and I don't feel inclined to use 10.5.3. I would use better 10.4.9 ones, which were mostly reported as OK, but doesn't seem a pretty safe operation.
Anyway, my external HD was working fine under 10.5.4 in a different machine and doesn't work in this new one (also 10.5.4), so I'm not sure about the results, but I won't trash this external HD, as it works fine in every other machine except for this one
Already many posts regarding USB issues, I hope Apple fixes this ASAP, as most of peripherals today are purely USB-based. I think this issue regards usually to external HDs. Surely some simple lines of code mangled across the various OS updates

External Firewire Hard Drive is not recognized

Hello
I have a LaCie External Firewire Hard Drive (like this one (http://www.lacie.com/us/support/support_manifest.htm?id=10105). Since it uses a fireware 400 cable, I bought a FireWire 800-400 adapter, the one from moshi that is sold in the mac store.
I have tried connecting it to both ports in the external harddrive, connecting and disconnecting and still is not recognized. Any idea and suggestions?
I already tried in another computer, with windows xp, and the hard drive works.
Thanks.

Hi, oops, I have more than 1 mac & I apologize for assuming you are a multiple mac owner..
You could visit your local Apple Store or Local Apple Approved Service Agent.
You could try connecting via USB if your external HD has the capability, it could also be a bad cable.
You can check the Finder -> Preferences & the Show These Items..
You can reboot with the Ext HD connected & see if it shows up on your d/top...L

Hard drive will not mount after optical drive upgrade

I recently performed an optical drive install. Had to remove the hard drive bays (I use three hard drives - Luckily, 2 run OSX).
I carefully removed all three drive bays and the empty bay. When I inserted the drives into the computer I had changed the position, swapping one OSX drive with a different one and reversing the drive bays. On restart, the computer started on the drive I had not selected for startup and I received an error message stating the other drive could not mount and it gave three options (Initialize - Ignore and Eject).
I can see the drive in Disk Utility and repair the permissions (it's also located in the System Profile).
I tried a few things I read in the community using various Terminal commands but was unsuccessful.
(Let me point out that I recently switched from a PPC G5 to MacPro and swapped the drives from PPC into MacPro and all has been fine until I removed changed their positions in the bays)
Any suggestions/help would be greatly appreciated.

I would recommend you reformat your drives that you brought over, and if possible put in a Firewie case.
Swapping drives will normally not matter but you should use Startup Disk to reset the default after using Option key the first time.
Putting in an optical device shouldn't require removing the drives to get the cage loose and let you put in a 2nd superdirve.
G5 used APM partition map, Intel Macs use EFI and requie GPT/GUID.
A drive with just data should not matter but that is not fool-proof either.
A drive iwth the system from a G5 though can.
During startup the boot process scans all volumes and looks for systems and mountable volumes.
Pull all the drives except the one with OS X that you were using, and put that in bay #1.
I've moved arrays between bays and that never "broke" the array or had trouble mounting and using (even moving to ODD ports).
