Since upgrading to Lion I can no longer mount my external hard drive

I backed up about 10 minutes before installing Lion when I was on Snow Leopard. I know my drive works fine and there are no issues with it.
However, when Lion was installed, I wanted to perform a Time Machine Backup, but it said my backup disk was unavailable. I checked in the Finder and it wasn't showing up in the side bar, even though it was connected to my Mac and the indicator light on the hard drive itself was flashing - suggesting drive activity. I can also hear the drive spinning.
I opened Disk Utility and the external hard drive appears in the side bar and it says 'WD My Passport 071A Media'. Underneath that is the 'Time Machine Backups' drive which is greyed out. I have tried right clicking on it and choosing Mount but it won't mount, and I have also tried Repair Disk which doesn't finish, but also doesn't report any errors either. If I run Verify Disk and Repair Disk on the 'WD My Passport 071A Media' drive (which is the same drive) it does not report any problems and says the drive is working fine.
I have tried updating the drive's firmware and using different ports but neither have worked. I have also tried rebooting my Mac.
I really need to use this drive to backup and I can't format it because I can't afford to lose any data on there. Could someone please give me some advice or tell me how to fix this? I would appreciate it so much.
Thanks,
Nathan

If you want.
or maybe install Snow Leopard using the disc it came on with my Mac and just set it up from a Time Machine Backup on my external hard drive (since it works under SL)?
Did you install Lion on an empty partition, or did you upgrade Snow Leopard? If you upgraded, I'd not recommend erasing it, since your backups are apparently gone. It's doubtful Snow Leopard will recognize them.
It's not just backups on the drive either, there are other important things on there, so why won't they show?
Mixing Time Machine backups and other data is not a good idea. See #3 in Time Machine - Frequently Asked Questions. It sounds like the whole disk is corrupted.
I just really don't understand how this happened. Could it not be an issue with WD because they haven't issued firmware to support Lion yet?
If this is a simple external HD, connected by USB or FireWire, no, unless you installed some of WD's software on it. That shouldn't prevent it from being seen at all, but anything's possible.

After I installed Lion, my MacBook Pro can no longer detect my external hard drives or my USB flash drives. What should I do?

And me -- My Mac at work running Snow Leopard reads the drive normally. My home Mac (on Lion) can't even find it....
Yet another Leo let-down.....

Why can't I see my external hard drive, Intel iMac / 500 GB, G-Drive

Why can't I see my external hard drive? I have a new iMac, Intel based i5, running Lion (2-3 months old). I have a 500 GB G-Drive external hard drive that has showed up when connected to my iMac for the past 2-3 months. Now it's gone. It's NOT visible when using Disk Utilities. I have all of the radio buttons chosen in the Finder Preferences. I've unplugged and replugged in the drive, have switched the cable ports and have switched firewire cable. The G-Drive powers up and whirls, so I don't believe the problem is with the drive. Yes, I set my Preferences to make sure ALL disk types are visible. I've restarted my iMac on a number of occations. I rest my SMC by totally unplugging my iMac for a minute, then plugging it back in. Any suggestions?

Unplug the HD, Zap the PRAM, reconnect the HD, power it up, and see if that fixes the problem. If not, then maybe the HDs bitten the dust. Try on another computer to verify.

Can no longer access NTFS external hard drive

Have been using the new Mac-Book Pro for about 4 weeks now. Until last week, when I attached by Seagate NTFS formatted external hard drive to my USB port, it showed up in Finder right away and I could access files ( read ) on it without any problems.
But since last week, if I attach the same drive to my USB port, it no longer shows up in Finder. I cannot see it at all !!
Any ideas ? All i need is to read files from it, I don't need to write anything to it.
Thanks.

BTW, after talking to a Apple-Support personnel and doing a bunch of hard-ware tests they recommended that I format the external drive to a FAT32 partition.
Not a good solution, as XP cannot format a drive using FAT32 for drives more than 32 GB, the drive in question is a 100 GB capacity.
I just want to read the NTFS partition on the Mac. Don't need write access. I thought Leopard supported "read-only" access to NTFS drives. What drives me crazy..is that Leopard could see and read this drive fine until last week.... What happened !!
Thanks for your inputs.

Can no longer access USB external hard drive

Hi - I am running OS X 10.8.4 on my iMac (21.5-inch, Late 2009), and have been using a La Cie USB external hard drive for several years for my Time Machine backups without issues. All of a sudden yesterday, the external hard drive disappeared from Finder and my Desktop, and as a result, no more Time Machine backups I rebooted both the external hard drive and iMac several times and changed the USB cable but with no success. Disk Utility and Time Machine cannot see the external hard drive but it does appear under System Information => USB (see below). I connected it to my Windows 8 laptop. The Windows laptop can see the external hard drive under Disk Management as an uninitialized disk. But I will not allow me to initialize it and therefore cannot acces it.
Product ID:          0x0951

Any help to restore the external hard drive would be appreciated.
Ron

Thank you for your quick response. Disk Utility does not see the hard drive. Windows 8 does see it under Device Manager and says that it is working propoerly but it will not allow me to initialize it.   As indicated to Lin Davis, I'll buy a new external hard drive.

Can no longer access my external hard drive

My husband I and switched to a Mac after using Windows machines for years. We have a Free Agent external hard drive to store ALL of our music files and, most importantly, our photos. When we first got the Mac, we plugged in the FreeAgent and it worked fine (obviously, I couldn't write to it, only read the files, but that was basically fine). In the last few days, I realized I can't access the drive at all, no icon, nothing under Computer, no ability in iTunes or iPhoto, nothing. I unplugged its and powered both the Mac and the FreeAgent down, and then reconnected everything and that did not help. Any thoughts or suggestions? It would break my heart to lose my photos. I have a lot of them backed up on removable media, but I take a lot of pictures and stand to lose hundreds.
This is a possible duplicate post, so please bear with me. Our Mac was purchased at the end of May 2012, but we have not upgraded to Mountain Lion. As the Genius in the store put it the night we bought the computer: it's better we learn our way around the system as it is now without all the extra bells and whistles.

Thank you so much for your response. I tried your steps this evening...both of them, and still don't find the FreeAgent drive. I don't have my Windows laptop here at home, but will bring it over so that I can connect the external drive and make sure that there's still DATA on the darn thing. If all the files are still there and can be accessed through a Windows machine, then I guess all is not lost. I'll have to look into purchasing a new external drive to work with the Mac now.
I apologize for the lack of info on my system. I am brand new to Mac - as stated, we only purchased our first-ever Mac back at the end of May and then I almost immediately started a new job, so I haven't really had time to get to know the ins-and-outs of the system. For instance, I don't know where to look to get OS info..all I can tell you is that the machine is 4 months old and I haven't installed Mountain Lion yet. I don't have a boatload of apps installed either - pretty much what came with the computer with the additon of MS Office for the Mac, which I needed for work and school.
The external hard drive was initially used with Windows machines, so when it WAS working with the Mac, I wasn't able to write to it, but the files were all there. Because there are days at a time now where I don't come near the computer, I can't say when the FreeAgent stopped working with the Mac.
Thanks for your help, and if you have any other suggestions, I'd be very appreciative.

I updated FCPX to 10.9 after I had updated my os to 10.9.1. And the result is that FCPx can no longer read LaCie external hard drive where all the projects and events are stored. The program simply crashes every time I try to read anything from the LaCie.

Could anyone tell me what to do to solve the problem. I updated FCPX to 10.9 and the program keeps on crash every time I try to read files stored in my LaCie hard drive. And the program also keeps on crash every time I try to import files from my SDXC cards.

I have solved the problem. Once the update is done, you need to launch FCPX, and go to File, then "update all events and projects". It will solve the problem and everything works fine.

Hi,
I tried everythink, but same as before!
- droppings ot the main screen
- loosing Home Share
now even on iPads !
Frustrating!
I'm now more than convinced that this is caused by the latest iTunes version.
As some others stated in other threads .... it seems that Apple doesn't really take care of this problem. So what if, if we could make them feeling the same pain as we do. ... Just by dropping them a mail as soon as we have the problem again. Not more often, we don't want to be unfair, but everytime it happens.
I found this feedback site http://www.apple.com/feedback/itunesapp.html
I will start now with this.... maybe this will help to rise a little bit of attention
Tweety
This is the mailbody I always use
Hello all,
Since the last update to iTunes Version 10.6.1 (7) streaming content (Movies and TV shows) to Apple TVs and iPads has two major problems:
- Home Sharing is lost during streaming (streaming stops even if a large portion of the content is already preloaded)
- streaming stops and the main screen pops up (Home Sharing still available)
This happens sometime after some minutes, sometimes after several hours, but it surely happens.
I followed every advice I could found on this support website. There are now a lot of threads following this issue.
Sometimes it seems getting better, but hours later the same isues occured again. Watching content on this enviroment is a real pain and very frustrating.
As many others I'm now convinced that the latest update of iTunes caused this problem.
Our family enviroment contains the following Apple products:
- iTunes on a Win7 32 bit Noname PC (all content)
- second iTunes on a iMac with OS 10.6.8 (all content)
- third iTunes on a MacBook Pro with OS 10.6.8 (daughter, only selected content)
- fourth iTunes on a Win7 32 Samsung Notebook (son, only selected content)
- all iTunes sharing the same Home Sharing ID
- 2 Apple TV second generation
- 1 Apple TV first generation
- 2 iPod touch (bought last year)
- 2 iPads (second generation)
all firmware or software are on latest available patchlevel.
At this moment, I can not recomend to others to buy this products.
I will drop this feedback everytime my famiily and I facing this problem... just to help you to get a better feeling of the urgency of this issue.
Thanks for every effort in advanced.

Some have reported success simply by reinstalling the update.

Or download and apply, or reapply, the 10.6.8 Combo update first, then apply the Security Update again.

I'd suggest starting with the simplest of these fixes, so look them over first.

the benefit of this https scan feature is at least questionable. in order for it to work, avast has to perform a kind of man-in-the-middle "attack" in order to get to the content of the encrypted connection (firefox supports a feature called [http://monica-at-mozilla.blogspot.co.at/2014/08/firefox-32-supports-public-key-pinning.html key pinning] which can be used by websites to address such MITM attacks and which also seems to pick up AVAST's interference).
when you download files over a https-connection, they will be scanned by your AV software once they land on your hard-disk anyway. on the other hand it should be the job of the browser to make it impossible to get infected by malicious software by just surfing around...
''edit: please try to restart the browser again, it may take a new session for the change to take effect.''

After the latest update I can no longer see my iPhone listed on the left column - how do you get to where you can pick

After the latest itunes update I can no longer see my iPhone listed on the left column. How can I get to the section where I can pick & choose apps etc to be synced?
Also I had to get a new iPhone & so I backed up the night before to the cloud & my computer. When I tried to restore from back up with the new phone my back up wasn't there - shouldn't it be automatic via wifi from the cloud?
What am I doing wrong?

Your iphone is shown at the top of the page.
You can also simply click View>Show Sidebar and it will look about the same as it did before.

Solved the problem by dumping my external HD onto another computer. Re-formatting and re-installing the data. Not what I wanted to do but it solved the problem.

Why can I see my external hard drive?

For 2 years or more I've had an external hrad drive to back up my Imac. One day I got a message that there had not beeb a back up for for a really long time ( I have it on automatic).
Ever since, I have not been able to see the external hard drive on mi Imac and have not been able to do regular back ups.
First I turned off, on, restart computer and tried to see if it showed up on another computer, which it did.
What could the problem be? It was working just fine.
Please help
Thanks

EHD's can crash. First thing I'd recommend though is to do 2-3 SMC resets. Shut down the computer, then remove the power cord from both the wall plug and back of the computer, wait 15-20 seconds and restart normally and test.
If that fails use another cable to connect the drive, if that fails open Disk Utility and see if the EHD can be seen. If that fails then replace the drive. I would STRONGLY recommend 2 backups, use Time Machine on disk 1 and then use a create a clone using either SuperDuper or Carbon Copy Cloner on the other drive. When it comes to backing up, redundancy is smart. Would you trust your bank if they only had one form of backup of all your money??
