Error when encrypting external hard drive

When I tried to encrypt my external harddrive I get the message "Core storage volume is already encrypt". And it isnt. It has been but i decrpyted it for a couple of days, and no I cannot encrypt the disk. Can any1 help me?

Triple-click anywhere in the line below to select it:
{ diskutil list; echo; diskutil cs list; } | open -f -a TextEdit
Copy the selected text to the Clipboard (command-C).
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window (command-V).
A TextEdit window will open with the output of the command. Post the contents of that window, if any — the text, please, not a screenshot. The title of the window doesn't matter, and you don't need to post that.

I downloaded several cds to my external hard drive in .mp3 format. Later, I copied them to iTunes. The songs only play when the external hard drive is plugged in. I tried to load the songs from iTunes to my iPhone and the songs don't play.

I downloaded several cds to my external hard drive in .mp3 format. Later, I copied them to iTunes. The songs only play when the external hard drive is plugged in. I tried to load the songs from iTunes to my iPhone and the songs don't play. I thought iTunes allowed me to transfer music to my iPhone and play it. What am I doing wrong?

Hi skoorb1,
When adding music to iTunes, you can set it to either make a local copy of the file, or simply point to the original location of the file (for example, on an external hard drive). If it is set to do the latter, it will not be able to play or transfer those files when the external hard drive is not plugged in. You may find the following article helpful:

Are you talking about a Bootcamp partition? You can't boot Windows from an external drive.

Error when exporting to hard-drive

Lightroom 4 was working fine before I tried to export to Flickr. The export was NOT successful, and after that, I encountered an error when exporting to hard drive. Although this error appears, the export to hard drive is always successuful. It is annoying to continuously receive this error message. Any help will be much appreciated. Thanks

That is the small trouble with screenshots: as unambiguous and helpful as they are they are hard to search for their content.
But it looks identical to several other posts here (http://forums.adobe.com/message/4341436#4341436, http://forums.adobe.com/message/4318154#4318154, http://forums.adobe.com/message/4285253#4285253, http://forums.adobe.com/message/4261252#4261252, http://forums.adobe.com/message/4177871#4177871):
In your export manager select "Do nothing" i.o. leaving it blank. down at the bottom where it asks for what to do in Post Processing After Export.
This should have the message go away.
For the sake of searchability I spell out the error message, so that others could find this being answered:
Unable to Export:
An internal error has occurred: Win32 API error 2 ("The system cannot find the file specified.") when calling ShellExecuteExW from AgWorkspace.shellExecute.

Itunes freezes when my external hard drive is plugged in

Awhile back, in the summer, I upgraded to the newest version of itunes, and ever since, itunes doesn't work when my external hard drive is plugged in (which contains most of my music). When I unplug it, it will play the music on my computer, but when it's plugged in, it won't work at all and only freezes. I reinstalled it, and then slowly started putting some music in from the external hard drive, and it worked, but after I put a bunch in it froze up again. I have no idea why this is happening, as it was never a problem before. SUGGESTIONS?!

Either use the startup key commands or use System Preferences>Startup Disk to select the external hard disk before you shut down.

Error message pop up when connecting external hard drive to eMac

Hi,
The external hard drive's icon don't show on desktop when the Maxtor 6Y160P0 Media connected to the eMac. Running the Disk Utilities still can detect the external hard drive.
After a while, it pop up a message shows that "You have inserted a disk containing no volumes that Mac OS X can read. To continue with the disk inserted, click Ignore." It has three options – Initialize, Ignore, Eject. Choosed "Ignore" to continue but useless. The external hard drive still spinning but can't access to backup data.
Sometime the icon showed after restart the external hard drive, unpluged the cables and pluged in again then restart the eMac. Sometime after doing these also no response.
Is there a fix for this?
Thank you!

If the previous user always SHUT DOWN the computer (vs. just sleeping it) then that wouldn't be the cause because when you shut down, the Mac OS closed up everything and dismounts the drives anyway. So shutting down without ejecting the hard drive and then turn the drive off after the computer is off is perfectly safe.
Is there something on the drive now that you need or would it be ok to simply reformat it and start over?

No "decrypt" choice in contextual menu - need to decrypt an encrypted external hard drive

I have a Firewire 800 external hard drive that I had previously encrypted using the contextual menu. I want to change the password on this drive so I'm trying to decrypt it and re-encrypt it while assigned a new password. I have Filevault 2 enabled on my iMac but this shouldn't affect this external drive. I also have a Firmware Password enabled on this iMac, but again, this shouldn't prevent a "decrypt" option in the contextual menu.
"Encrypt" is present in the contextual menu. When I attempt to use this option it appears to allow me to assign a new password. When I click "Encrypt" I get this message: "The target Core Storage volume is already encrypted." It's true that the drive is already encrypted, that's why I'm trying to decrypt it.
I'm running the latest version of Mountain Lion on a late 2012 iMac. I've searched online for someone with a similar problem, but haven't found this problem reference. Does anyone have any idea as to why "decrypt" is not an option on this external drive, but it is on similar external drives that are also already encrypted. Thanks.

Thanks for your help, Linc. By the way, I mistakenly said I had Filevault and Firmware turned on. Actually, they are NOT enabled on the iMac. Here's what I got in my Text Edit window:

You're trying to encrypt a bootable volume. To do that, boot from it and activate FileVault in the Security & Privacy preference pane. It's only possible if the OS X version is 10.7 or later.

Slow boot time Mac Osx when USB external hard drive is connected

I have bought some days ago an external hard drive, the Western Digital 500 GB Elements.
It goes very well by now but I have a problem.
When I turn on my MBP, after the "bong", I have to wait 60 second more than the normal boot time.
The screen stay grey and after 60 second it appears the apple.
It appens only when the external hdd is connected.
Someone has a solution?

Some time ago, I read that the OS has a problem waking from sleep or booting if an external was attached (USB or Firewire), something about it being confused about the startup order. Anyway, since then, I have religiously followed this procedure when I'm done using the external: unmount, unplug, and then turn it off (if necessary). I have never experienced a problem with my Mac not recognizing or not being able to boot because of an external. It certainly doesn't involve more than a second or two to unplug a USB drive.

HT1751 So what happens when the external hard drive with all of my iTunes media on it crashes??

I moved my iTunes media/library (as well as iPhoto) to an external hard drive many moons ago. It's been a great decision up until today, when the portable hard drive I was using decided to commit suicide. Is it possible to restore the lost media and library files from Time Machine, or are all of my music (and picture) files officially gone??? Help!!

If you have been doing the basics and backing up your computer, then they are not gone. They are in your backup.
Use your backup to put them back.

ITunes Locking Up When Using External Hard Drive

Has anybody else had any trouble with ITunes locking up for about 30 seconds at a time. The music keeps playing but the cursor locks up and you can't click, use hot keys, etc. I'm using a 150GB external hard drive to store my music and while it's locked up the hard drive is crunching something, almost like ITunes is looking for something. All of my files are organized, no viruses or spy-ware that I can find. Doesn't happen with any other audio program, just ITunes. I've watched the CPU usage on Task Manager when it happens and the only thing that is running is ITunes. Please help!

I came across your post because, I have been having issues for a while with the same description, except that I am using separate partitions on my main drive.
What I noticed is that if I set my podcast downloads to go to my NTFS main partition, there is no lag... but the moment I set it to my FAT32 partition, the lag starts back up.
I believe that the issue is with the slooow write time to FAT32 in large drives. (And in my instance, the move command apple does to put the podcast, which writes to the FAT32 partition and removes the NTFS temp download) Do you see the same lag or alot shorter if the drive is formatted to NTFS?
I don't really have any space currently to format my partition to test the issue, but I the fact of the downloads speeding up when set to my NTFS main disk makes me think that this issue could be lessened by using FAT32.
a side note for me, I'm considering reformatting my drive to NTFS, after backing up due to the advancement of ntfs3g in linux, so this could solve my problem at least.

Screen Lock When searching external hard drive?

Why would my screen be locking up when I try to access my external hard drive? It shows the folders contained in it, but won't let me scroll down to see the rest or open the folders when clicked on. when I try to use the menu at the top I just get the spinning wheel. I have to force quit to get back to my main hard drive, which works fine. I'm able to access the folders through lightroom so I feel like the hard drive is not at fault.. Any help or ideas would be greately appreciated

…and I suspect you want some clairvoyant or mind reader to guess all the details and specs of your setup?

If I start up when my external hard drive is plugged in Mac doesn't boot up

If my external hard drive is connected to my MacBook when I turn it on, Mac OS X does not load. What can I do to make the computer load with my external hard drive attached?

Either use the startup key commands or use System Preferences>Startup Disk to select the external hard disk before you shut down.

Ethernet not connected when using external hard drive

My brand new Mac Mini (mid 2010) works fine when I connected it out of the box to my router via Ethernet cable. But when I boot that new mini using an external hard drive (La Cie 500 GByte Firewire 800 connection), the Ethernet shows up as "Not connected". It advises that I should plug it in, or the other end may not be plugged in. But when I simply reboot again to the internal hard drive, without changing any connections, the internet connection works fine. When I boot a different and older Mac Mini (2.0 GHz Core Duo) off that same external hard drive (using Firewire 400 of course), the internet connection works fine. I'm stumped despite using Macs since 1986. I tried automatic mode, but I can't get far, because it thinks there is nothing plugged into the Ethernet port. But there is, and it even works when booting off the internal hard drive. Both the internal and external OS are at 10.6.4, latest. I also tried erasing the internal hard drive so it couldn't get confused, but that didn't help. What else to try?

The ethernet service has nothing to do with the cable plugged or not, and the ethernet cable is working fine with the other system, so definitely the issue with your other OS. Forget about the working OS for now and boot into the OS that has the problem and select the ethernet service from the service list in System Preferences > Network then click on minus button then apply the changes then click the plus to add it again.
If this didn't work, go to :
/Library/Preferences/SystemConfiguration
and trash the NetworkInterfaces.plist file then restart and see if it solves the issue.

Grey 'rolling' screen when using external hard drive

Hi,
I have the mid 2009 MacBook, and recently started having issues when plugging my 500GB Seagate external hard drive into the usb ports. I plug it in, it shows up in finder with the name, but when I click on it to view the contents, the grey screen comes rolling down and asks me to hold down the power button to reboot.
I tried reinstalling Snow Leopard (I'm on 10.6.4) but it hasn't worked.
Would appreciate any ideas.

What are seeing is a kernel panic*:

Since it only happens when plugging in your external hard drive, it sounds like either there is a hardware issue with the ports, the drive has specific software that has not been tested with Snow Leopard for connecting the drive, or issue with the cables you are connecting with. Follow my tip for isolating your issue.
