Thunderbolt port on MBPR wont mount external drive

I have a 2012 MBPR and the thunderbolt port wont mont an external drive? I have returned the drive and tried again with another with same issue. any ideas? update says everthing is up to date.

I don't know a thing about the Buffalo drives... it gets good reviews at MacMall... if I were you I would exchange the drive - there may be a simple problem with the TB cable. Or you may have just gotten a dud. One reason that I stick with the LaCie drives is that I've always had good luck with LaCie in general and, having had good luck with the 4TB, I went ahead and purchased the 8TB. I don't know that MicroCenter has LaCie drives but do know that Apple Stores carry them... but I would, at least, get an exchange for your Buffalo and see if that solves the problem.
Good luck,
Clinton

Time Machine can not be mounted - external drive

I have an external Maxtor USB drive that's been my time machine since forever. Yesterday I noticed that it's not mounting. I KNOW it was mounting the day before because I had to use it. But now the drive is not mounting, and I don't know why.
The drive is on, the light is on, but it's not mounting. Out of curiosity, my husband hooked it up to his Vista PC and he was able to browse to it all dandy. But then back on my computer, it's not being recognized.
It's not showing up in disk utility, though my other external drive, my iphoto drive, is having no problems. It's not the USB port, as my ipod works on either port, as does my iphoto drive.
Can anyone help?
I've unplugged it, plugged it back in. Rebooted the computer without it attached.

I solved my problem. I tried plugging it into another computer and it popped up on the screen. AHA! Before I tried that, I had ONLY unplugged the drive but had NOT crawled under the desk to unplug it from the main power source. It just needed to be TOTALLY unplugged and left alone for a few minutes. Those little green men obviously can bunch up anywhere and need a total disconnect, for several minutes at least, to unbind. Ahh, sort of like un-constipating the system?

How to recover data from non-mounting external drive?

OK- here is the pinch:
I have a Western Digital My Book 500GB Studio Edition which, though visible in Disk Utility, fails to mount, even when I try to do so via Disk Utility. I have tried all the usual- unplugged, repowered-up, changed the order of Mac to external drive power-up/plug in etc etc. It will not mount, end of.
Then I changed the housing, in case the issue was with that. No change.
Then I had a friend use his PC's software to recover the data and he pulled off what appears to be ALL of it (it was close on being the 500GB as the drive was full) but it is not usuable and the Final Cut Pro and iMovie files I am needing to recover, appear to have been "downgraded" to MPEGs and MP4s (how IS that even possible?!) with a few MOVs of which the bulk are unreadable. Oddly the clips are transitions only- no full three and a half minute (most of them are of music, songs of about that length) clips ever.
So- is there any chance that I can get software which will let me recover the content of the drive in a format which my MacBook Pro can use/understand? Or is it a lost cause?
I had done some research on the topic here and found one thread which mentioned accessing the drive via the "Terminal" (sounds wonderful, if I knew what it was and how to use it) and correcting a read and write setting, copying its content over to the hard drive (well- that is not possible as I have a smaller internal than that drive is but no never mind) and getting the non-mounting drive to once more mount.
Could that ^ be something worth pursuing? I cannot ask on the thread as it is from 2006 and, obviously, archived.
Hoping for some good news but am resigned almost.
Thank you for reading!

Did you try using a powered USB hub?
Mac's now cut off port powered drives if they draw too much current.
The external drive is a powered SATA, currently residing in a powered SATA to USB housing, no extensions. No, the drive is actually just not supported anymore and was not mountable before.
Also use the Mac version of Data Rescue for file recovery, it knows the Mac file formats better than PC file format recovery.
I cannot recover anything with a Mac because the Mac will not read it. It is not supported due to something my friend did with his PC:
This is only since he had a go at recovery. Before then it was supported and appeared fine- just not mountable.
Obviously what happened is it took the MPEG portions of the Mac files as it understood that and discarded the rest.
Yes, I gathered that and explained as much to him. It discarded the entire 120GB FCPro project file I kind of would like to recover.
Not sure what now...
You had mentioned cloning/imaging etc. which you edited out. Could that be something which can be done with a PC (I am not a PC user but I guess I could have a go) and then I use said image on the Mac to copy the bits I need to transfer to the Mac-formatted storage device? Or- with a different Mac? Not sure why that would make a difference but I am happy to try anything!
Thank you to you both christopher rigby1 and ds store- means a lot not to be completely up the creek without a paddle. I just wish that I had not been overwhelmed by the offer of assistance from a PC user and had had more of a go myself. I suspect it would not be this difficult now.

Cannot mount external drives

Hi all!
I have an 2010 imac i5 32GB RAM, running on 10.9.2.
All of a sudden my machine does not mount ANY extrenal hard drive. It recognises them in Disk Utility, but they appear greyed and cannot be mounted. Not even disk repair. Last week though the drives were mounting on the system without any problems.
Yesterday I have upgraded the OS to 10.9.2. (from 10.6.8). Still the same problem, the drives are recognisable in DU but cannot be mounted.
All of the disks I've tried are NTFS format (originally formatted on a pc). Funny thing is I have VMware Fusion on my mac runing a virtual Windows 7 pc. Windows do recognise the drives and mount them without problem, but not the mac.
Also note that I'm using Tuxera NFS to work with these drives with no problem so far, until now.
Also checked the cables, I'm connecting the drives though USB ports, they are ok.
Any suggestions?

just guessing you are using USB to mount the external. you may need to use two usb ports to mount the drive. that means a cable with two usb connectors which should provide enough power to the external.

Can't mount external drive

I have an IOmega 1TB external drive that I use for my Time Machine backup that I always leave connected through a usb port.
It had been working until this past week.
I check the manufactures troubleshooting guide and I was able to check that the System Profiler does recognize the connected drive. I also tried to use Disk Utility to 'mount' the drive and I wouldn't let me.
Does anyone have any idea what I can try. This is my backup drive and can't loose all the info.
Thanks

Hi Rossana,
In Disk Utility, Verify Disk, does that report it's OK or not?

Can Time Machine back up data stored on a mounted external drive?

Can Time Machine back up the data that I have stored on an external drive? It's mounted on the desktop but I can't seem to add it to Time Machine.
Is it that Time Machine doesn't back up mounted External Hard Drives? If so, does anyone have a hack?

then the problem is not those external drives. As I said, I've never seen this particular error message.
Try using a different connection or a different port for your TM drive. If that doesn't help I'm afraid your options are very limited.
Unfortunately, TM is configured in such a way that when anything goes wrong, there is usually nothing a user can do short of reformatting the TM drive and starting backups anew. I'm very much afraid that's what you are looking at.
At least, I have no other advice to offer.

USB wont recognize external drive

I see that there have been a lot of problems with the usb ports recognizing external hard drives. Some of the fixes are so confusing, I cant even follow them! Does anyone have an easy fix for this problem or do you think apple care will know? i have used this drive for about a6 months with no problem, and then all of a sudden my Imac wont recognize the drive.

HI
You should check in System Profiler, under the USB section to see if the drive appears there (Apple -> About This Mac -> More Info -> USB)
Also, try resetting the SMC & PRAM to see if that helps

PowerBook wake on Sleep-then kernel panic when re-mounting External Drives

Hey all, I found a peculiar behavior with my PowerBook and my Lacie External Hard Drive. If I wake up my PowerBook from sleep, either by shaking the mouse, or opening the lid- the computer sometimes kernel panics when it attempts to re-recognize my partitioned 250 gig external hard drive. This seems to happen 1 out of every 5 times. The external is already mounted that I can tell upon waking; its just that it seems like it panics when it tries to recognize it again. Any one else experienced this? I've had this problem since I've had my external drive, and that probably dates back to 10.4.2. Thanks!

Hi, Zach.
You might want to try a different FireWire cable, a different FireWire port on your Mac (if available), or contact LaCie, the latter as the enclosure may be malfunctioning. Another potential problem area, although this also usually shows up as spontaneous dismounts of the FireWire drive, is the FireWire drive's power supply, i.e. its power brick, but that seems less likely here.
While it certainly seems like you've isolated the cause to the FireWire drive, you may also want to review my "Resolving Kernel Panics" FAQ. This FAQ includes step-by-step instructions for identifying and resolving some of the most common causes of kernel panics. The FAQ is a roadmap: start at the beginning and work systematically through the end, i.e. the "If all else fails..." section.
Good luck!

HT3382 With a MacbookAir (mid-2012) using a mini DisplayPort to VGA adapter plugged into the Thunderbolt port, can you configure the external monitor to FULLY display in portrait mode yet keep the built-in display in landscape mode?

With an 11"-inch Macbook Air (mid-2012) using a mini DisplayPort-to-VGA adapter plugged into the Thunderbolt port:
Can you configure an extended desktop with an external monitor (20") displaying full portrait mode (1200 x 1600 resolution) and keep the built-in display in landscape?
I'd like to see something like

Yes, I can't see why not.
Just give it a try and report back if you have a problem.

Disk utility wont format external drive

Hi all
I have a friends 1 TB toshiba external drive, purchased at office works. I am trying to format it for NTFS so he can use it to watch the movies he is copying on any machine, xbox etc..
using disk utility I am erasing the 1tb drive with the NTFS format option, then I am creating the partition with NTFS but after formatting, it is only allowing me to read. I have tried formating the hard drive with Mac OSX journaled and then creating the partition at 1tb with NTFS, but getting the same issue.
I am a little confused as I just did the same thing with my 2TB drive I purchased from Office works as well.
any ideas?
bret

Hi Bret. I am not sure I fully understand the details of your problem - the mention of another drive (the 2TB one) confused me a little. I'll try to help though because it doesn't look like anyone has had a chance to reply to your question yet.
As far as I can see, OS X doesn't write to NTFS formatted drives by default. It appears you can enable it by altering the mount options, e.g. http://learnaholic.me/2013/11/11/enable-ntfs-write-on-mac-os-x-mavericks/
Alternatively, perhaps just formatting it as FAT32 would achieve your aim - although now that I check, it doesn't really look suitable as it has a 4GB file size limit and some of the movies could be over that.
Hope that helps.

How to mount external drives

Being new to iMac and connecting four external drives I need to know how to mount and dismount them

noondaywitch
Thanks for your help and I've followed your reply and yes I can see how to mount and eject drives.
Probably it would have helped if I had told you that my drives are all USB.
All connected to a small four way hub which is then connected to one USB socket in back of computer.
One - I use as a music drive and is a 160 gb iomega
Two - is a partitioned drive for Photoshop use 340 gb WD
Three - is a drive which has all my ex-Windows computer files and is one TB WD
Four - is a Video and Film drive of one TB WD
Five - is my dedicated auto backup drive which is of one TB WD and is connected directly to a USB socket of computer.
I normally set my computer to sleep until the next time I'm using it, then when I do go to use it, I get the warning message regarding drive was not ejected. Didn't have problems like this on PC so I became worried that in time I'm going to loose files and or the complete drive. Which one is giving me this message is also a bit of trial and error problem. Like suck it and see.....lol.
Anything else you can help me with this query would be most helpful and appreciated. Like do I have to eject all drives before leaving computer and then mount all the drives again for next session.
Regards
John

Mounting external drives with UID in Openbox?

I've just changed my system from gnome to openbox as my main WM.
In Gnome, my external drives were mounted as i connected them, with the UID.
Now, in OpenBox with every filemanager (pcmanfm2, thunar + thunar volman installed, nautilus) i tried, they are just being named
"disk [insert number]" again. how do i change this behaviour? which terminal outputs do you need?
Last edited by gpunkt (2010-05-30 11:11:55)

I don't quite understand what behavior you got with Gnome. Is that the filemanager "names" the drives with their UUID?
For me, the filemanager shows the drives with their label names.

Cannot mount external drive on network when no user logged in

We have a few workstations on our network that have multiple accounts for users in order to preserve preferences, etc. An external hard drive attached to the each workstation, holds work done on that station by the different users. When all users are logged out, the external drive does not appear as a mountable device when trying to log into the workstation from another computer; only the internal drives are seen and mountable.
Is there a way to make the external drive visible and available for mounting over the network when no user is logged in? The external drive is set to ignore permissions for that drive in the get info window.
Additionally, when a user is logged in to the workstation and someone tries to log in over the network to access the external drive, the drive is sometimes available over the network and other times not. What causes this inconsistency?
thx, j

You really want to format it HFS+ wiyh GUID Partition scheme to ensure your data transfers correctly...
How to format your disks...
http://www.kenstone.net/fcphomepage/partitioningtiger.html
(On IntelMac the Drive it needs the GUID Partitioning scheme mentioned at the bottom.)
Not sure if that'll make it see it or not, but your data will be better. Besides, you should be able to install to that then & maybe boot from it to ease matters.

Cannot mount external drive

I can't mount my TOSHIBA 1.5 TB external drive on my 15' Macbook Pro Retina.
What should I do?

download Tinker Tool, if you don't have it already.
Open Tinker Tool, under finder > finder options
select "show hidden and system files", relaunch finder.
Close Tinker Tool, using finder navigate to /Volumes directory.
If there is any left over references to your USB drive, remove them
(drag them to the trash).
Open Terminal.app
at the prompt:
sudo disktool -r
(press return, enter your admin password, press return again)
should give the message: Refreshing Disk Arbitration ...
close terminal
