Ext. Drive will not mount however it shows in Disk Utility?

Ext. Drive will not show on the desktop nor will it mount however, it shows up in Disk Utility but...
Back story: I've been using this Lacie backup on my MBPro with Time Machine. Decided to use the ext. drive to back up my old G3 yosemite running OS 10.3. It would not show on desktop so I decided to pass on that. Went back to my new MBPro, plugged it in and states disk utility cannot repair. "disk1s3" See images.
Help!! I have stored data on this drive and it was working great until now. Something must hae heppened going from the G3?
Anything help would be appreciated.

The disk directory is corrupt and can't be repaired by Disk Utility, or the drive has failed. You could remove the drive mechanism from the enclosure and install it in another one, or in a drive dock. If the mechanism is intact, you may be able to recover your backups that way.

OWC Mercury ext. drive will not mount via FW 800

Hi,
I just tried to hook up my OWC Mercury ext. drive to my new Mac Pro via FW 800 on the back panel and the drive will not mount. It does not show up using disk utility. Any suggestions would be greatly appreciated. Thanks, Mike

Try shutting everything down, and unplugging everything for 10-15 minutes.
Then, plug things back in in this order: the external drive firewire cable at both ends; the mac's keyboard and mouse, then the AC power for the mac and the external drive, and lastly, anything else you have hooked up.
Turn on the external drive first, then start up the mac and see if it shows up.

External Hard drive will not appear on desktop or in disk utility. HELP!?!

I moved my hard drive from upstairs to downstairs. there is no damage to the drive. Yet, now when I try to connect the drive, it powers up, but doesn't show an icon on the desktop, or an icon in the disk utility. The drive is still under warranty, but I don't want to send it back for a new one without all my info on it.
a) How can I get this drive to be recognized?
b) How can I get my files off of it before returning the drive?
Already tried:
• Disconnecting and reconnecting after powering off the computer.
• Using a different USB cable
• Using a different USB port
• Connecting to a different Mac
• Connecting to a PC laptop.

Actually, I did solve the problem myself, for free. To see if the adapter was giving enough power, I used a voltage meter. I found out the adapter I had it plugged into was actually giving TOO MUCH power. (Even though it was a 12 volt adapter, it was measuring 18 volts.) I figured out which adapter came with the drive and plugged it in using that one (also a 12 volt adapter, weird) and voilå - it appeared on the desk top as if nothing had changed. You can bet I'll be making DVD back ups tonight however, as the adapter kicking out too much voltage may have damaged the power board at some point, which may cause it to fail prematurely.
Thanks for your suggestions.

My external hard drive will not open and only shows up in Disk Utilities. When I try yo repair it, it give me and error of invalid sibling link. How do I fix my external hard drive?

My external hard drive will not open and only shows up in Disk Utilities. When I try yo repair it, it give me and error of invalid sibling link. How do I fix my external hard drive?

Invalid sibling link may not be fixable by Disk Utility. (Disk Utility is very conservative, and will not attempt repairs that might cause you to lose data.)
It is an indication of serious Directory damage.
that leaves
a) third-party Utilities that will take those risks, or
b) re-initializing the drive (which deletes all your data) and restoring from another backup source.
c) "Copying off whatever files you can salvage" has gone by, and you cannot copy anything off a drive that will not mount. You may be able to use "rescue" programs such as prosoft engineering Data Rescue to copy files to another drive, but that sounds a lot better than its reality. You may get many files, but not get ANY filenames.

Ext HD will not mount

My lacie HD - forwire 200 gig will not mount. It shows up in disk utilities but not on the desktop. In the info section of disk utility, the smart status is not verified. It seemed to go wacky after the last security update.

Lacie offers this advise in their FAQs. Put in FireWire drive and Mac OS for the search fields.
1) Try a different cable.
2) Repair the Permissions. Open the Disk Utilities and click on the First Aid Tab. Highlight your 'boot volume' on the left side of the window and click on 'Repair Permissions'. (Don't bother verifying first. It takes as long as repair and something always needs repairing).
3) Shut down, power off and disconnect all devices. Unplug the computers power cable (or remove the battery if a laptop). Wait about 15 minutes. Plug everything back in and boot up. This may reset the bus.

External Drives will not mount

Hi guys ... this is my first post in these forums, so sorry if it is in the wrong category.
I have a Mac Pro, purchased in Feb this year. I have an iOmega Ultramax firewire drive, that is partitioned into four disks.
I have had time machine running well, and it backs everything up onto a second iOmega drive I have.
Yesterday, before I left for work, I saw TM was sbusy backing up. The finder was not responding but I just left it, as didnt have time to loko into it before leaving.
When I cam home last night, I saw it was still not responding, and TM was still trying to backup. All other apps were functioning fine.
I tried to force quit Finder and TM, but it did not work. I then shut down the Mac manually, and rebooted.
The problem has now arisen, where the partitioned drives will not mount at all. The TM backup drive is fine, and I can browse TM fine with it - so good to know all my data is backed up.
I looked at the logs in console, and see the messages saying that the drive cannot mount as it is dirty?
What I have tried as troubleshooting steps:
•Disk Utility to try and mount the drives, but they are not showing up
•Connecting the drive to my Mac Mini - still nothing.
•DiskWarrior - nothing. Only my TM backup drive and Mac HD show up.
•Running FSCK from Terminal. I can see the drives in /dev, but keep getting "Bad Super block" errors. When I try looking for another Super Block, it says nothing found, and would I like to run it manually? The same happens when run in single user mode.
•Unplugging the Mac and the drives from the Mac, waiting 5 mins, resetting the NVRAM and PRAM (booting up holding CMDPR and waiting for the second chime, shutting down, plugging in and turing n drives, rebooting ... nothing!
It seems as though I have exhausted all possible options.
I now accept that the drive is unrecoverable, and am relieved that the TM backups are OK. I am thus happy to format the drive and repartition it, then restore everything from TM. Will be a fairly big job, but at least the data is backed up.
The only problem I have, is I cannot even mount the drives to format them!
Is there any safe way of doing this over the command line. Or even better, has anybody gt any other advice as to options I can try?
I hope I have been thorough enough in my explanation here.
Thanks in advance,
Dave

The only problem I have, is I cannot even mount the drives to format them!
I have a feeling that the partition map is bad. Does the drive itself report to DU? If the drive does show up, you can select that, and click the Repair Disk button under the First Aid tab. If that doesn't fix it, with the drive selected, click the partition tab and re-partition the drive. After that, I would erase the newly created volumes with 1-pass/zero out option selected and restore the data that was on the external from TM.
If none of this works or if the drive itself (not the volumes) doesn't show up in DU, you either have a bad drive or bad controller in the external case. How old is the Ultramax? Just wondering if it might still be under manufacturer's warranty. I would check to see if you are still eligible from the manufacturer's warranty and get the whole external unit replaced. If you are out of warranty, I think it likely that you need to replace that external with a new one. I've had a drive go bad in an external case (this one I could still mount but the heads would 'freeze') and the controller on another external go bad (this one, the drive would not report to DU so I took the drive out of the enclosure, stuck the drive in another case and there was no problem with the drive.)

10.9.1, decrypted G-Drive will not mount

I encrypted a 4tb G-Drive and later decrypted it. Now the drive will not mount. It does appear in disk utility but not in the finder or the desktop. To troubleshoot I rebooted the Mac and the drive (and I powered both completely down), I tried a different usb port (but since it appears in Disk Utility I didn't think doing this would matter). In Disk Utility the drive shows 16mb free (I have less than 1tb data loaded to the drive).

Solved my problem - no help needed - and I feel kinda dumb.
In Disk Utility the drive was greyed out. I simply right clicked on it and there was an option to unlock the drive. I clicked on unlock and was prompted for the drive password - entered password and the drive is now on the desktop and in the finder. Problem solved.

After upgrading to Mountain Lion, my LaCie USB 3 drive will not mount

I just upgraded my OS to 10.8 and now my LaCie P'9230 USB 3.0 external drive will not mount. I have re-installed the USB driver and re-booted the computer and drive several times to no avail; any ideas/help?

It's my understanding that LaCie hasn't released a Mountain Lion driver for their PCIe card yet. Sonnet uses a modified version of the LaCie driver and theirs is dead in the water too for that reason-they also warn that their driver won't work with 10.7.5 when it's released.
Indeed, yesterday I pulled the Sonnet USB 3.0 card from my Mac Pro and replaced it with a CalDigit card from OWC; CalDigit has separate drivers for 10.6, 10.7 and 10.8 and I can say that the card works with all three, the first time in 1.5 years that I've had a reliable USB 3.0 connection.

How do I repair a hard drive that was being written to while my MacBook Air crashed? (Drive will not mount)

My external backup drive will not mount. I have tried to mount it in Disk Utility via the app and the command prompt but the attempt times out. Any suggestions?
I backed up my HD the day before dropping off my Mac for repair, and then tried again just before going to my appointment. During this last and final backup my Macbook Air crashed. I have since discovered that the drive will no longer mount, likely due to the crash that occured during the last attempted backup. I am unsure if the drive can be repaired.
My logic board was short circuiting some where that controls the headphone jack. Initially this prevented me from using the jack but eventually caused my mac to crash several times before I brought it in for repair. I believe that it is the this crashing that is responsible for my back up not being accessible but that my data may still be intact.
Thanks for any help you may have!

If possible, attach it to another Mac and see if it is recognized in Disk Utility. If so, run Disk Utility>First Aid. If not, the HDD may be damaged.
Ciao.

Hard Drive will not Mount

I have a Seagate Barracuda 1.5 Gig installed in a MacPro as an additional drive and as of today the drive will not mount. Yersterday I noticed it ejected itself; I immediately rebooted and started to download the data to another drive but it ejected itself again after about 25% complete copy. I attempted to "verify drive" with Disk Utility but it was not listed. This morning it will will not mount. The drive is still under warranty so replacement is not an issue. Where I am at a loss is recovering the data. I fired up time machine and there was no data from this drive backed up (Bay 2). I checked the preferrences and the drive was not "excluded". So, I'm at a loss as to how or if I can recovery any data. I removed the drive from the MacPro and fired it up in a docking station (SATA) without results; still will not mount. Is recovering my data beyond hope? Any ideas or tips would be appreciated.
Thanks,
Koyangie

Hatter,
Tried Recovery Mode without success. Although the drive appears in Disk Utility I get an error after selecting Restore! If I click on the Image icon it will not list the contents.
There is perhaps .6 TB on this driver (images). After I posted and received yourt reply I took another look at my Time Machine and found all my data under Shared. What a relief.
Thanks for your advice. I'll return the drive to Seagate for a replacement. Hopefull I will be able to format it before sending it back.

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.

Dropped WD external hard drive will not mount

Hi there,
First ever post on this forum!
I have a mid-2010 macbook running Mountain Lion
A 2TB Western Digital Hard Drive dropped to the floor while plugged in and spinning.
I reconnected it, and after a few minutes mounted, showing all my files. There is NO RATTLE and it powers up with the light flashing.
I ran Disk Utility 'Verify Disk' to check if there was any damage - this ran ok for a few minutes but eventually Disk Util froze and crashed and the drive disconnected. Any attempt to reconnect the drive then froze the computer for a few seconds then didn't mount
I disassembled the drive from the case and USB circuit board and put it into a caddy - the drive again spins when turned on, but does not mount - doesn't appear in Disk Utility, and strangely when disconnected (physically unfortunately, no way to dismount it) the drive keeps spinning, and the 'USB device has been unplugged' warning appears in Finder
When connected in system profile, it doesn't appear on the USB device tree
Finally, I ran the diskutil list command in Terminal and the drive briefly appeared, but when I ran the diskutil mount command, I was told 'device not found' - now diskutil list no longer finds the drive
What to do?

There are companies which offer recovery services which could include disassembly and repair of the HD's internal mechanism or other sophisticated methods but that's going to be an expensive proposition. If, when the platters start spinning, you can't hear the ticking of the heads seeking, that type of recovery is likely all that's left. And that's assuming the platters themselves weren't damaged by the heads when the HD hit the floor.

External drives will not mount if wi-fi is on

I was really unsure where to post this. If you think it should be in a different thread then let me know.
My problem is this. I have a Macbook that I use at home no problem. I teach at a college where there is a wi-fi connection that my Macbook automatically connects to. Recently, I have discovered that any external drives will not mount until I switch the wi-fi off. Additionally, almost everything I try and do causes the spinning beachball for 10 minutes or more at a time.
I have searched the net and cannot seem to find any reference to this problem anywhere else. Any ideas at all why this might be happening will be much appreciated.

It was not until Mac OS X 10.6.4, not possible to run on a 10.2 machine, that ExFat was supported.
Many older Macs also will not recognize GUID formatted partitions made to boot Intel Macs either.
10.2.3 is the first system to support Apple Partition Map HFS Extended (Jornalled).
There may be NTFS support based on my tip here:

External drives will not mount if the wi-fi is on!

I have had no replies where I had previously posted so I thought I would try here as I think that it is mainly an Airport problem.
My problem is this. I have a Macbook that I use at home no problem. I teach at a college where there is are two wi-fi connections that my Macbook automatically connects to depending on where I am in the department. Recently almost everything I try and do causes the spinning beachball for 10 minutes or much more at a time. Additionally, I have discovered that any external drives will not mount on my laptop, unless I switch the wi-fi off! No-one else is having any problems at all.
One of the wi-fi connections is an Airport Extreme. Each morning my laptop gets the message that there is a problem and I need to update the firmware to 7.5.2. (I originally set the Airport up through my laptop) I am very wary of doing this as everything is working fine for the other 20+ laptops in the department and I have read lots of reports of problems with this update.
I suppose my questions are these - 1 Does anyone have any idea what is going on with my laptop? 2 What should I try doing to solve this issue?

Firewire drive will not mount

Firewire drive will not mount USB mounts fine.

It's nearly impossible to offer any help given the dearth of information you provided.
What Mac are you using? What external FireWire hard drive are you trying to use? Is it a FW-400 or FW-800 interface? Have you tried any other FireWire device with that computer? Have you tried that FireWire drive with any other computer?

Ext. Drive will not mount however it shows in Disk Utility?
