External hard not mounting

Upgraded to Lion last night on a macbook pro. Now my external hard drives will not mount. Get the following error message. Is there a fix. Cant reformat because they are 2tb disks mainly full of data.
NTFS-3G could not mount /dev/disk2s1
at /Volumes/PenfoldPC 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)
They worked perfectly in Leopard

Your external drives must use NTFS, and you were using MacFuse to write to them, which does not support OS 10.7.x yet, i suspect this might be because it's a 32-bit kext and lion defaults to 64-bit kernel mode? don't quote me on that. But if true you might be able to use MacFuse if you force lion to boot into 32-bit kernel mode.
However it might be better to uninstall MacFuse which hasn't had a release in a long time, and use OSX Fuse instead, which is supposed to support Lion:
https://github.com/downloads/osxfuse/osxfuse/OSXFUSE.pkg
You need to uninstall MacFuse first, If you have the latest version installed then there is an uninstall button in the macfuse pref-pane (look in your system preferences), if not then you run the uninstall script manually by pasting this into your terminal (it will ask for admin password):
sudo /Library/Filesystems/fusefs.fs/Support/uninstall-macfuse-core.sh

After installing Mountain Lion doesn't external hard drives mount or stay mounted. Anybody else with this major problem?

After installing Mountain Lion doesn't external hard drives mount or stay mounted.
I have tried resetting my Mac's PRAM but the problem still remains.
Even USB memory sticks are unmounted efter a few seconds.
Anybody else with this major problem?

I have the same problem, although mine has not been solved by ESET update, finder settings, PRAM & SMC resets or anything else.
Don't get it, my external hard drive still works on both my housemates computers - one macbook pro (with snow leopard) and one dell, just not on mine with mountain lion.
Any ideas for me guys?

TS1550 Do external hard drives mounted on my Mac get backed up by time machine on a time capsule wireless Apple external back up disk? How can I see what folders have been actually stored in the wireless back up disk?

They can provided you remove them from the Exclude list. Normally, Time Machine does not automatically backup external drives.

External Hard Drive Mounting Issues

Hi everybody!
Problem:
My G Technologies external hard drive mounts inconsistently since the Pro Tools session I was working on today crashed. When it does manage to mount my Trash Bin on the dock fills up with trash automatically and this trash cannot be emptied.
In addition I have been unable to even open up my external hard drive on the desktop once it has mounted--I get the infinite pinwheel of death! If it does open, I'll eventually get to a folder that upon opening also brings up the pinwheel of death. Each time this happens I am forced to manually shut down my computer. Any suggestions? You help would be GREATLY appreciated! Thank you in advance.
I'm using a MacBook Pro with OSX 10.4.11 and it has a Intel Core 2 Duo processor. The ports I'm using with the external hard drive is Firewire 800.

Try booting in safe mode and emptying the trash. Try doing a Finder - Secure Empty Trash deletion....
I believe your problems are related to large files that were marked for deletion not being deleted...

External Drive not mounting anymore. HELP!

I was messing with permissions. I was trying to restrict others from using my external drive. I do know that I never removed myself. Now I see that my external LaCie 250GB drive will not mount. Both 'Disk Utility' and 'Disc Warrior' see and 'repair' the hard drive, but it still does NOT mount on the desktop. What can I do? Please help!

I opened a 'Terminal' window and discovered that it appears I changed the owner. My username is bobbysteele. I changed it from 'admin' to my username (it's truncated - bobbyste). The permissions on the external drive are as follows:
d---rwx--- 16 bobbyste bobbyste 646 Jan 7 08:01 Jukebox01
It appears the permissions should be drwxr-xr-x because that is the setting for all other drives and folders. How can I change the permissions? Please help.

External Hard Drive mounts, but can't be selected or opened

I have a 1 TB Western Digital external hard drive. When I plug it into the Firewire 800 port of my 13" Unibody MacBook Pro (running Snow Leopard), the drive shows up on my desktop and in Finder windows, but when I try to access the drive, or "select" it, I get the message "The alias "[name of drive]" can't be opened because the original item can't be found". If I select the fix it option, it gives me a finder window to identify the item to which I want it to refer (the hard drive), but when I select the hard drive in this window I get the same message. I've used Disk Utility to verify the disk and it says that it is fine. Also, I have two other external drives, a smaller WD drive and a smaller Seagate, and they both mount and are accessible. Any thoughts?

having the same issue with a mounting a hard drive that drovers is. any solutions? funny thing as that the drive will mount on a G5 running 10.5.8. have spent several hours on the phone with apple help to no avail. final suggestion was to wipe drive and reformat. cant't do this as I do not have enough space to back-up to. Would appreciate any suggestions.

[Solved] External Hard Drive mount point in fstab crashes launch

Hi there,
I have an external hard drive that I'd like to automount when I plug it in. Sometimes it seems to work, but other times I have to manually mount it. In order to make this a little easier, I copied the mounting info into my fstab file so that I could just run:
mount /dir/to/mount
However, now I can't actually boot up my machine unless the external drive is plugged in. I get some error from systemctrl saying one of the drives couldn't be loaded.
An obvious work around would be to write a one line script that mounts the drive for me, however, I'd like to learn how to do this correctly. I think the rules have changed a bit with systemd, as I didn't have this problem a few years ago.
Thanks for the help!

Thanks for the answer, that fixed it.
You're welcome but I think Mr.Elendig's post gives the actual solution (my proposal is just a workaround -- using fstab for a filesystem that is not permanently attached is sub-optimal)

Firewire External Harddrive not Mounting

I recently bought a 1TB Seagate internal drive and put it into a casing, and have been using it for Time Machine backups on my white Macbook. I was using FireWire, but all of a sudden the harddrive either doesn't mount at all, or if it does, the backups stall and never finish. It works fine through USB. I tried rebooting the computer, rebooting the harddrive, and clearing my computer's pRAM. When I first started using the harddrive, I was using a basically completely fresh install of Leopard (10.5.6).
This is only the first time I've tried to use the FireWire port on my computer since I bought it in summer 2007, so I'm wondering if maybe the port itself is faulty. Is there any way to determine if this is the case? Should I just take the computer and the harddrive to the Apple Store? Any advice will be helpful at this point. Thanks.

You might want to check your firewire cable, too. It seems that the drive is working (since it can back-up through USB) so the next step in the chain is the Firewire cable. If you have a second one, try that. If not, borrow one (if you can) and see if that fixes the problem. Most cables that I have used are pretty good, but, on occasion, you can get one that either has been stepped on or damaged in some way.
The mac checks internal operations first before it looks at peripherals (your external hard drive) so, if you were having a problem with the drive or the cable to the drive, it would stop the start-up operation there.
If you have some other device that uses the firewire port you might want to try that too, just to see if the port is having some problem. I would use a digital video camera and iMovie to see if it can see the camera or not.

External HD not mounting since update 10.9, not enough power

Hi,
I have troubles with a Lacie Rikiki USB 3.0 external hard drive since I updated to OS X mavericks: when connected via USB, the disk starts to make noise, but the LED indicator stays off. I have tried several things, from formating the disk in all available formats to downgrading the Macbook pro (mid-2010, 13inches) to OS X Mountain Lion. The disk does not mount and does not appear in the disk utility soft. I have the same problem on a late 2009 iMac, on OS X and Bootcamp since the upgrade. Apparently the disk doesn't get enough current from the USB port, but I can't figure out why.
Thanks if you have any idea.
Rémi Grosjean

If that drive doesn't work on any Mac then it might be the drive has failed. you could also try a Y USB cable that connect to 2 USB ports at the same time to supply more power to it.
Mac notebooks have always had low power output on the USB ports. Mavericks might even lower that trying to save power.

After Leopard upgrade external drive not mounting

Ok, after finally getting through the dead blue screen issue I have Leopard up and running.
New problem, my external USB hard drive (I/O Magic 80GB USB 2.0) will not mount. I've used this drive up to and including the day I started the upgrade as my backup drive. Now when I plug it in it does not mount, I cannot see it listed in Disk Utility and it does not show up in the System Profiler. Can anyone suggest what I need to do to get this to work?

Update:
I brought it (third time's a charm?) to the Apple Store once again: the iMac, the WD My Book, my cables, etc. They tried it; no luck. They tried the My Book in their computer (think it was a MacBook running Leopard) with my cable; showed up no prob.
One other interesting thing this tech did was look in Apple Profiler for Firewire, where there was an odd Warning in red that no Firewire devices could be found. (This while plugged in to 400 Firewire port w my cable.) Then tried it plugged in to my iMac w 800 Firewire cable; voila! It appeared! Then tried another device in the 400 slot; it showed up fine. (huh?) Tried a different 400 FW cable w My Book in iMac, no luck.
The tech looked bemused. He sold me an 800 FW cable and told me to try sending the cable back to Western Digital.
Meanwhile, twelve days after contacting WD about this problem, they responded with this link:
Thank you for contacting Western Digital Customer Service and Support and I apologize for the delayed response.
We have seen a couple of issues with Leopard.
The following link Addresses formatting issues with certain drives used with Time Machine
(specifically, single-partition MBR drives greater than 512 GB in size as well as NTFS drives of any size and partition scheme). http://docs.info.apple.com/article.html?artnum=306907
The following link addresses the latest release updates to the Leopard operating system 10.5.1. http://www.appleinsider.com/articles/07/11/12/latestmac_os_x_10_5_1_build_fixes_finder_data_lossissue.html
I haven't used Time Machine yet (will get different external for that if I decide to) so the second link was more applicable to my situation.
I did just install 10.5.1 a couple days ago, it didn't resolve this for me; since other devices worked in the 400 port, the tech thought perhaps it was a software issue...<grin>
Hope others have equally simple solutions..

SOLUTION - USB 3.0 External Drives Not Mounting on MBP Retinas - SOLUTION

So I have been having the same problem as everyone else who has issues with USB 3 external hard drives not mounting on their MBP Retinas. My friend told me to try unplugging the USB cord and plugging it back in instantly (like in half a second, so as to not let the power turn off on the drive). I had my doubts but then I tried it just now, and MY DRIVE MOUNTED.
GO TRY IT AND SEE IF IT WORKS FOR YOU!
UPDATE: I am using a powered external drive (Seagate Backup Pro 3TB). Not sure if this will work with bus powered drives, but I think it might, as my friend might have been using a bus powered drive.
Also, I just bought two Hitachi TOURO 750GB bus powered portable drives (7200rpm/USB 3.0) and they mounted perfectly without problem as soon as I plugged it in for the first time.

Did you unplug the USB cable from the computer or from the external drive? This fix has been posted here previously but it was reported that the cable had to be unplugged from the device, not the computer. If the cable was unplugged from the computer instead, the fix didn't work.

Seagate Goflex external drive not mounting

Upgraded to Yosemite with no problems. However my Seagate 3tb external drive will not mount, but it is recognized in the disk utility and it is recognized on a pc but will not mount? Is there anything I can do? I tried the goflex thunderbolt dock, Ive tried usb, Ive plugged it into an older imac with 10.7 on it and it says "unrecognizable drive" and gives me options to initialize or eject. Is there anything I can use to just get these files off of here on win or osx?
I have also plugged in two 1tb drives seagate and toshiba and they both work perfectly. And, I have also updated the thunderbolt drivers and all that... I am at a loss of what to do next.

Okay found out the problem, on my exfat formatted drive, after I upgraded to Yosemite it basically created a new partition, a corrupted partition and would not mount my drive. However, I could open it and see it in Disk Utility.
Here's what I did to fix it:
Goto disk utility to see the name of you drive.
Open Terminal and type: sudo fsck_exfat -d disk1s1(this should be the name of your disk)
It will ask for your password then press, enter and it will display all files on the disk.
Then is will ask: Main boot drive needs to be updated?
Type: Yes
It will update and say that you can repair disk in disk utility.
Do that, and it will show up on the desktop.
Link to original forum post if you need more information:
https://discussions.apple.com/thread/4154638?start=0&tstart=0
Hope this helps, it was a headache for about a week but, Ive read osx does not handle exfat formatting very well.

External Firewire not mounting

Since the quicktime 7.5 updater I have been unable to mount ANY firewire devices. A check of the system profiler shows under firewire,(in red) "Unable to list FireWire devices."
The same external drive when using USB 2.0 connection does indeed mount and work properly suggesting there is now a problem with both FireWire and FW800 connections. Ive tried everything listed in every forum and the issue persists. Since finding this "Warning" in the system profiler Ive decided to post with the hopes others may recognize the same issue and perhaps we can find a solution.
Onward and thanks.

Hi Dennis,
I read your thread with interest because I just installed Leopard X.5.3 on a partition on my iMac G5, and the FW 400 devices that had been working fine were not mounting. I, too, have a Belkin FW "powered" Hub, and I was beginning to think it was bad. I had even gotten the same error in red in System Profiler/Firewire/Firewire device Tree/"Unable to list Firewire Devices".
So as I wrote this note, I'd say 5 minutes after the problem started, the drive (actually a mirrored array of 2 drives) appeared. I have since tried to mount the other drives I have connected to the Belkin Hub, and they wouldn't show. I connected the hub to my other iMac and unforunately 2 of 3 Mirrored Arrays are showing as degraded. Only the 1 "good" array appeared on the Leopard install on the iMac G5.
So I guess I've got to remember to unplug devices when doing a system install? That's must be how these guys got hosed?
YMMV.
So long for now, TOM

External drives not mounting

My external drives are not mounting on my desktop. When I chekck my about this mac, more info, system report, firewire the message is Warning: Unable to list FireWire devices.
Just out of the blue my FireWire 800 externals don't mount? Have mounted all of them to my MacBookPro no problem. Not daisey chained simple front and back worked just fine now nothing.
Anyone have a solution?
Thanks in advance,
Mark

Mine take a very very long time to mount then they will not sleep even when unmounted. The firewire driver in Mavericks needs some work. If at all possible, I would use USB until the driver get's resolved.

Why won't my external hard drive mount?

Hi
I am having problems getting my new iMac to recognise an external hard drive. It is a 40gb Western Digital hard drive that I copied over photos and music from my old computer (not an Apple) on. When I plug it in to the USD port it recognises the hard drive but then drops it after about 2 minutes and then it won't recognise it again until I restart the computer at which point it recognises it again for 2 minutes.
The hard drive work's fine on my Thinkpad and my Dell desktop.
Can anyone help?
Thanks.

It doesn't make sense.
Anyway, I found the solutions. Download software for solving this problem.
