External Hard Drive Suddenly Disappeared From List

Hi guys. About a week ago, a weird msg started popping up about my external (F:) hard drive, after which nothing inside of it would show up anymore.
If I clicked on a folder, there'd be nothing in it. Then if I unplugged, and re-plugged, it would all be back like nothing happened.
Yesterday, the D: drive disappeared from the population list in My Computer altogether, and no matter what I do it doesn't return. I've only tried plugging into different ports and restarting, but that's all I know how to do. I was going to system restore and
see if that helped, but this message came up on the screen:
"Changes made to drive(s) D: after this point cannot be reversed because the drive was either excluded from system restore monitoring, or was turned off or removed"
I have no idea what to do. Literally everything is on that drive. Any suggestions? And thanks in advance for any help, it'd be appreciated.

Just tried it on another computer and the drive didn't show up there either.
Its a Seagate FreeAgent Desktop harddrive.
What can I do?

External Hard drive has disappeared from fcpx

Hey guys,
I know this question comes up a lot so I'm suprised to say I've failed to find any fixes on other threads. Many people having the same issue say that the drive shows up temporarily in the events and project source windows but then disapear, this is not the case for me it just doesn't show up at all. I've put 90% of my fcp projects and events onto one external hard drive which is working fine with everything but fcp, it even recognises it if i want to import from the drive. It has been working fine up until now which is weird as I've not changed anything on it recently, the only thing I've changed is I used a client's drive to do the latest edit, which worked fine!
Someone must have found a solution to this problem by now, it's causing me a lot of trouble as I've got deadlines to meet and I'm being put out by what seems to be a ridiculous little bug, surely apple would have got onto a fix for this by now?? In the mean time all and any suggestions welcome!

Have you used it successfully with FCP X before? What content has changed in the drive?
I am assuming you checked all the usual things, but still it is worth taking a look again:
1) Is it formatted as Mac OS extended?
2) Did you add any folder titled something that may be thought of as a camera (folders like "AVCHD", "Private", "DCIM", "Video", ....)
3) Are the folders called exactly "Final Cut Events" and "Final Cut Projects" and located at the ROOT of the drive?
It seems like you know all this, but still there may have been something you missed.

Volume on External Hard Drive Suddenly Disappeared

Hello
I'm having problems with an external hard disk which i partitioned into two volumes several months ago. Since this afternoon one of the volumes will NOT mount on the desktop of OSX 3.9 The other volume on the same external drive DOES mount.
I restarted my mac using OS9 and the mystery volume reappears on the desktop, (which is reassuring because i can see that all my files are all still there). But some of these files are only useful to me with OSX applications.
How can i get this volume to mount?
I've already tried in Disk Utilities. It's name appears, but in that faded colour which means that my mac knows its there, but refuses to mount it - even when i ask nicely in Disk Utilities. I even asked Disk Utilities to run a check of the disk and do any necessary repair work.... which it did and now tells me that the volume "seems ok"! But unmountable :((
I've just tried connecting the disk to a neighbour's mac (OSX) and same problem, even using his cables. But i can still get the mystery volume to mount on a OS9 desktop...
Would be grateful for THE solution :)) ...urgently!

Hello! I've seen problems like this before and sometimes Diskwarrior can repair the directory for that volume when diskutility can't. Have you tried booting from the install cd to see if disk utility can see and repair it there? Tom

My external hard drive has disappeared

My external hard drive has disappeared from the 'open file' window in photoshop CS6. It's working fine and appears in other applications such as bridge and lightroom. How do I get it back? I'm running a Mac on OS X.

You may have accidentally dragged the drive out of the Devices list in the sidebar.
In a Finder window with visible sidebar, do Shift+Cmd+G to get the Go To Folder dialog. Enter
/volumes
then click OK.
You'll see all your mounted volumes in the Finder window. Drag the required one to the Devices list in the sidebar.

My Western Digital external hard drive suddenly stopped showing up on my Macbook Pro and disappeared from Disk Utility. It works on a PC.

My Western Digital external hard drive suddenly stopped showing up on my macbook pro and it disappeared from disk utility. I have tried making invisible files visible but nothing has worked and my hard drive shows up on a PC but not my Mac anymore.

What is the manufacturer of the external and how old is it? Does it have its own AC power supply or is it USB bus powered?

How can I edit lightroom 5 smart previews on mac book pro (mbp) when the lightroom 5 master image files are on my external hard drive is disconnected from the mbp

How can I edit lightroom 5 smart previews on mac book pro (mbp) when the lightroom 5 master image files are on my external hard drive is disconnected from the mbp? So far when I try to disconnect the external HD from the mbp, I get the following pop up window: The disk "external hard drive A" couldn't be ejected because "Lightroom" is using it. Quit that application and try to eject this disk again. When I do that and restart Lightroom 5, the Adobe Photoshop Lightroom - Select Catalog screen pops up but doesn't list my external hard drive A as a choice.
I've reviewed Adobe's Lightroom Help | Smart Previews Lightroom 5 web page and still haven't been able to figure what I'm doing wrong. Any help would be appreciated.

Your internal HDD. by default, is named 'Macintosh HD'. From what information you supplied, it looks like there is already a Lightroom catalog installed on you local (internal) HDD using the standard naming convention Adobe uses as well as a Lightroom catalog on your external drive which you created. To be sure of which catalog Lightroom is loading when it starts up, To do this, start Lightroom as you normally would. After it starts, select the Lightroom menu item, then select the Catalog Preferences item and finally, navigate to the General tab. The Location information will tell you exactly what catalog Lightroom is opening by default. This will likely be the Photography Mac Book Pro Versions catalog on your external HDD. Once that is confirmed, you are ready to proceed. As an additional test/verification, you can shut down Lightroom and, this time, start Lightroom while holding down the ALT/OPTION key. This will cause Lightroom to pause and display a screen which will allow you to chose a different catalog to open. Navigate to the /Users/[user name]/Pictures/Lightroom folder and select the Lightroom 5 Catalog.lrcat file. When Lightroom comes up, there should be no previews or folders as this catalog should be empty. Now you can be certain which catalog is being used and which catalog has all your data and you are ready to migrate your current catalog. Shut down Lightroom.
To migrate your current catalog, use Finder to locate your Photography Mac Book Pro Versions folder on your external drive. Select the folder and select COPY from the context menu. Next, use Finder to navigate to the /Users/[user name]/Pictures/Lightroom folder on you internal HDD. You can start at the Macintosh HD level and work your way down by opening each level (Macintosh HD/Users/[user name]/Pictures). Select the /Pictures folder and then select PASTE... from the context menu. When the COPY/PASTE is complete, you should see the following files on the Macintosh HD:
Macintosh HD/Users/[user name]/Pictures/Lightroom/ and
Macintosh HD/Users/[user name]/Pictures/Photography Mac Book Pro Versions
The Macintosh HD/Users/[user name]/Pictures/Lightroom folder will contain the empty default catalog the Adobe created when Lightroom was installed and Macintosh HD/Users/[user name]/Pictures/Photography Mac Book Pro Versions will contain a copy of the catalog you created on your external HDD.
You are almost done now. Make sure your external drive is still attached for this step. Restart Lightroom using the ALT/OPTION key again. When the Select Catalog screen appears, select the Choose a Different Catalog button (lower left side). When you do, a Finder window will open to allow you to navigate to a catalog of your choosing. Navigate to Macintosh HD/Users/[user name]/Pictures/Photography Mac Book Pro Versions and select the file Photography Mac Book Pro Version.lrcat. This is the copy you just created. Select the Open button and Lightroom should start. You should see all of your previews and settings just as before. Also, in the left hand panel, all of your folder should show up and none of them should be dimmed and none of your previews should display a small exclamation point badge. Either a dimmed folder name or an exclamation point badge indicates that Lightroom can't find the associated image file. If everything looks good, go to the Lightroom menu, select Preferences and then select the General tab. Under Default Catalog, select an option to either load the LAST catalog opened or select the Users/[user name]/Pictures/Photography Mac Book Pro Versions catalog from the drop down. Shut down Lightroom and then restart it normally. This time, when Lightroom starts, you should be viewing the new copy of your catalog. You can confirm this by looking at the General tab on the Catalog Preferences screen (Lightroom/Catalog Preferences menu items). Shut down Lightroom once again and this time, eject your external drive before restarting. This time, your folders in the left hand panel will be dimmed but you should be able to work with your smart previews. If Lightroom should display a Select Catalog screen with the external drive detached, double check your settings as it indicates Lightroom is still looking at the copy of the catalog on the external drive rather than the new copy you made.
Finally, if you are seeing dimmed folders and/or exclamation point badges with the external drive attached, this indicates a problem. You can select any folder and select Update Folder Location from the context menu. This will allow you to navigate to the copy on the external drive and select it. Lightroom will then update the catalog (select to synchronize the content). This will not only clear the dimmed folder problem but also remove the exclamation point badges for all photos in that missing folder. However, it may indicate that not all went well with the copy of the catalog so make sure to verify all went well. You can use the Get Info option on the two folders. You should see the same number of files/folders for both the copy on the internal drive as well as on the external drive but you can't rely on the byte count because of the possibility of differences between the geometry of the two drives. Hope this all helps!

How do I back up my itunes to an external hard drive and restore from same if necessary

How do I back up my entire itunes to an external hard drive and restore from same if necessary.
Thanks

This is where iTunes stores backups for different operating systems: http://support.apple.com/kb/HT4946
I do not use a Windows machine, have a Windows Vista Dell I rarely startup now. But, from what I remember with Win boxes is, you will have to create on the external hard drive a file system like that one iTunes normally uses, and then in the iTunes preferences or control panel edit the location for the storage to specify the name of the external hard drive, or its letter code, with the name of that file system you created on the exernal drive.
I would also move all of the files from the internal file system to the external since you have now told iTunes that is where they are...before deleting from the internal drive, test iTunes to see that it goes where you want it to go.

External hard drives suddenly changed to read only

Three of my external hard drives suddenly changed to read only. These hard drives have been working on my macbook pro for months. When I click on get info 'read only' shows up and there is no lock icon nor is there a window that shows name | permissions, also in disk utility the 'verify disk premissions', 'verify disk', 'repair disk', and 'repair disk premissions' buttons are ghosted and I can not select them. I have not made any changes to my computer and I have read many other posts and have not been able to find a solution.

About a hundred times with no luck. Some of my research is leading to Western Digital, there may be a problem with the drives' 'smartware' software. I've been using this drive for months and I never used the 'smartware', but I tried it anyway with no luck. I just remembered that four days ago I had this drive plugged this drive into an Iomega wireless storage device and it seemed to work fine. Now the wireless storage device can't find the drive at all. I just need to know if there is a way I can change the permissions back to read/write, otherwise I will have to buy another drive and transfer all the data to the new drive and re-formatt the wd drive.

Where did my Disk Space go?

I can't import my movies to work on them. They are coming from a external hard drive, not directly from the camera, its type mpeg-e (.mts)

My movies are type MPEG-2
I can't import my movies to work on them. They are coming from a external hard drive, not directly from the camera, its type mpeg-2 (.mts)
What can I do ?

1. Is your external HD connected by firewire?
2. mpeg2 is the final compressed delivery format of a DVD, not intended for editing, and iMovie cannot handle such files, so you need to convert them first:
For that you need mpegStreamclip:
http://www.apple.com/downloads/macosx/video/mpegstreamclip.html
which is free, but you must also have the Apple mpeg2 plugin :
http://www.apple.com/quicktime/mpeg2/
which is a mere $20.

HT1751 I want to copy the songs that are in my ipod in to an external hard drive and not from a itunes folder in my computer.

I want to copy the songs that are in my ipod in to an external hard drive and not from the itunes folder in my computer (the reason being is that the songs in itunes folder are not to my taste. Please help?)
I have the orignal ipod 120gb
Many thanks.

Bare in mind that Sync is only oneway, from PC to your device. Unless you have the same music on your PC, iTunes is going to wipe out what you have on your device if you are syncing to a new library.
You can only transfer Purchased music over to Itunes on your PC.
iTunes Store: Transferring purchases from your iOS device or iPod to a computer

As for you own music, you may have to use a third party software. A good Free one is called Sharepod which you can download from Download.com here:

Music from External Hard Drive suddenly not playing...

The other day I disconnected my external hard drive to use it elsewhere, plugged it back in later, then suddenly none of my songs located on it could be played on itunes...
Funny thing is that if I right click and go "show in windows explorer" it takes me to the correct directory on the external...however when I go to play the song the small speaker icon appears next to it, however without the "sound waves" that appear when a song is playing....
Can anyone help me out???
Thanks

If you have relocated the media folder to an external drive and then start iTunes with the drive disconnected iTunes will reset the media folder to the default location on the internal drive. It will also assume that all files on the drive are "not present". Correct the location of the iTunes Media folder, then close iTunes, wait a few moments and open it again. iTunes should now find your files.

External Hard Drives Suddenly being removed:

I have two different external hard drives that I use for storing video (1 Seagate and 1 Western Digital). Over the last few days I have had them powered up one at a time. After about 10 minutes, I receive an alert that says that a “device wasn’t properly removed. Material stored on the device could be lost or damaged.”
The Icon for the Ext. HD has disappeared. A few minutes later it re-appears only to have the same thing happen again in the next 10 or 15 minutes.
The Ext HDs are connected via the firewire ports on the back of the computer.
Per a one to one suggestion, I unchecked the "Put hard Disk(s) to Sleep when possible. It didn't help.
Anyone have a similar problem and know the Fix? It's two different brands of ext. HD, so I think it's my computer and not the ext. HDs.
These are my specs:
Model Name: iMac
Model Identifier: iMac4,1
Processor Name: Intel Core Duo
Processor Speed: 2 GHz
Number Of Processors: 1
Total Number Of Cores: 2
L2 Cache (per processor): 2 MB
Memory: 2 GB
Bus Speed: 667 MHz
Boot ROM Version: IM41.0055.B08
SMC Version: 1.1f5

same thing happened to me on my iMac the other day
the WD xdrive (plug 800fw) suddenly stopped working and did not show in finder (worked perfectly for 2 months)
ran a diagnostics program downloaded from WD's site to a PC and everything worked fine
i have another xternal plugged into usb so my guess - PROBLEM W/FIREWIRE!!

How to stop my Time Machine external hard drive preventing iMac from sleeping?

I have a late 2012 iMac, and have discovered that sometimes (I haven't noticed a pattern of when it doesn/doesn't happen) the computer will immediately wake up after I set it to Sleep (Apple Menu>Sleep). Through elimination I have found that it is the the USB 3.0 external hard drive I use as a Time Machine back-up that is the culprit; unplugging it then allows the computer to sleep. If I unplug it, then plug it back in later on, this normally solves the problem for a while, but not forever. This same Hard Drive didn't cause the wake problem on my previous '08 iMac.
A big issue is that when the machine immediately wakes from sleep, the display stays off (until I move the mouse) - this is good from a power saving point of view, but means I don't know if/when the machine is immediately waking from sleep (I have to listen to the fan when setting it to Sleep mode to hear if it has actually woken back up).
I've searched the forums, but can't find another poster with the same problem as myself. Can anyone advise a course for me to pursue to prevent this from happening?
Thanks. Jamie

Hi Frank. Nope, I'm still having the same symptoms; the plugged in external drive (TIme Machine) will wake the machine up a couple of seconds after it winding down when put to into sleep mode. Ejecting the drive and then sleeping the machine works. After plugging it in again to do a Time machine backup, it will allow the computer to sleep soundly for the first few sessions (eg a few days of sleeping, waking, sleeping, waking, etc), but then it will then suddenly start preventing it from sleeping again after a while.
It seems I'm fortunate in my case that the display stays dark (or off?) when the machine has been woken from sleep, but this was actually preventing me from knowing the machine wasn't in fact asleep for quite some time; I only eventually cottoned on because there wasn't any delay when 'waking' my machine (which there normally is). I would then have to carefully listen to the spinning fans to know if in fact it had gone to sleep or not.
So, to summarise, unfortunately no, I haven't solved this yet. If anyone else has a solution, please let us know?
Also, I've noticed occasionally after waking that there is a relatively quiet 'crackle' sound (kind of electrical sounding) from the bottom-right area of the machine. This goes on every so often for about 30mins. I see this is also an issue with other people's late 2012 iMacs, but I've not seen if anyone has a solution to it?

External hard drive mysteriously disappeared.

My external hard drive (Firewire) mysteriously disappeared. I can get it to pop up in Disk Utility, but I can't get it to show on the desktop. I've tried it on a few Mac computers. Do you have any idea what happened?

That's very strange. I don't think I've heard of DU exhibiting that behavior before.
I presume the reason you don't want to erase the drive is that there is un-backed-up data on it, and that if you could recover that data you could either reformat (erase) or dispose of the drive.
You may want to try downloading and using the free demo version of one or more of these data recovery utilities:
Data Rescue II
FileSalvage
VirtualLab
In each case, the demo will show you what files the full version would be able to recover from the drive. You can then decide whether the files you could recover are valuable enough to justify buying the full version of the utility.
