Update Deleted External Hard Drive

After installing the iMac EFI firmware update, two partitions of my iomega external hard drive are missing from the desktop. Two other partitions are still there. Any suggestions for locating the missing partitions? Thanks for any assistance.

It was a simple fix by unplugging and replugging the USB cord. All four partitions are back.

Can't update iPod - external hard drive permissions error

I'm trying to change file permissions on an iTunes folder on an external hard drive. I'm able to get to the folder, but when I open the documents info screen, the Ownership and Permission section of it is disabled and I can't change it. I'm the administrator of the computer- there are no other users other than me, so I assume I can change permissions for a folder.
The problem is that all the easy options (I'm no UNIX tinkerer) are grayed out. I don't have the option to lock/unlock, change permissions, etc... because there is no way to access these options. See the screenshot of the folder here:
http://digital-goddess.com/img/itunes_screengrab.jpg
I have tried changing permissions on the parent of this folder and applying to all subfolders, but that didn't change this folder or my access to it. This folder holds half my iTunes library and throws up an error that I don't have sufficient permissions to update my iPod. This is very annoying and worrisome. Any help?

Sorry, I forgot one step.
When you expand 'Details' a button called 'Apply to enclosed items..' appears. Click on that to apply all permissions to the files inside the folder.
You can also use a free (donationware) utility called BatchMod to set the correct permissions.
Hope this helps.

Edit:
Just realized, you have that folder on an external HD.
Apply the Ownership & Permissions to all contents of the drive to prevent possible trouble with other applications.

Boot camp without deleting external hard drive

Hi,
the external hard drive im using has 2 partitions. One for Time machine backups and one which I would like to use for Windows/Bootcamp.
Is there a way to only delete/format the Windows partition without having to delete the partition used for back ups during boot camp?
thanks

It is NOT supported. Windows-to-Go, Winclone or the link I provided are the options that you have.

Updating an External Hard Drive Operating System to Yosemite

I have a MacBook Pro (late 2007), it was upgraded to 500GB hard drive. I use the old hard drive as an external hard drive for backing up files from the MacBook Pro. It's operating system is version Mac 10.6.8 and formatted Mac OS Extended (Journaled). Can this hard drive be upgrade to Yosemite 10.10?

Yes. You'll be given the option to choose it when setting up the Yosemite installation.

10.4.7 Update Now External Hard Drives don't work w/Camcorder on

I just updated to 10.4.7 and now when I have my firewire camcorder (Panasonic PVD-252) connected, my two external firewire hard drives (both Lacie) do not work and it causes the Finder to freeze. When I turn the camcorder off, the problem stops.
I had heard of this issue with certain camcorders with older versions of OS X but it was fine before the update (in fact earlier this evening).

Yes to all. I even tried to connect it to my old iMac G4 (that I also upgraded to 10.4.7 at the same time) and it didn't recognize the camcorder either. I will have to borrow a friend's different model camcorder and see if it is recognized.
I also had a disk error that Disk Utility had to fix on both the G5 and G4 iMac that appeared after upgrading to 10.4.7. And for some reason the G5 would not boot from the CD/DVD where the G4 would. I tried and tried and the G5 just wouldn't boot. I ended up connecting it to the G4 using target disk mode in order to fix the thing. After that I tried again to boot using the CD with no luck.

How to update/refresh external hard drives?

Okay, lets say that you add some music to a memory card but later you want to remove those songs and add a new stack of songs... So you delete your old songs and try to add your new songs (keeping it in the size) but it wont allow you because the memory card/external says not enough space because it has not registered the fact that you have already deleted your old songs. Even though the songs do not show up, and the size is correct when plugged into any other computer just not the mac.
What to do?

After you delete the songs on the memory stick, you need to *empty the trash* to recover that space for reuse.

External hard drive spontaneously unmounted? Try these tips:
NEW FIRMWARE: Try updating your external hard drive's firmware, which is available from your drive manufacturers Web site--or just use VersionTracker's (www.versiontracker.com) search function to find it. Be sure to back up your data before applying the update, and carefully follow the manufacturers instructions.
OUT OF iSIGHT: If you're using an iSight camera while you're using a FireWire drive, the camera may be interfering with the drive's ability to stay mounted. Try temporarily disconnecting your iSight and moving it to a separate FireWire port. If you have multiple FireWire devices, try using a FireWire hub.
POWER PROBLEM: A faulty power adapter could be causing your drive to unmount. Your drive may not be getting enough juice to stay on, causing the drive to turn off and thereby unmounting it from your Mac. Alternately, the power adapter may not be providing a steady amount of power, causing your drive to turn on and off. Try replacing the adapter. If you can't get a replacement adapter from the hard drive manufacturer, try your local electronics store. Just make sure the adapter you choose has the same connector and input/output voltage. you can find the input/output voltage on the adapter itself.

I have just purchased my 1st mac and want to start my iTunes fresh. I have all my music on an external hard drive and want iTunes stored on it. How do i do this

I have just purchased my 1st Mac Mini,
I haven't imported any music yet except from purchased music.
I have 100gb of music on an external hard drive (already formatted to Mac OS Journaled.
I want my iTunes to be store on the External Hard drive, and to update my External Hard drive with new music I add to iTunes.
I also want to know the best way of adding my music on the Ext Hard drive e.g.: "add folder to library" or "import"
I plan on buying a Macbook Pro soon, and want to be able to use the same iTunes library.

Launch iTunes with the Option key held down, click on Choose Library, and specify it. If the external drive doesn't contain the iTunes database files, create a new library there and import that music.
If the library contains any rented movies, they won't play on a different computer.

External Hard drive wont show up in Finder

Hi,
After Mountain Update, the external hard drive icon wont show up in Finder sidebar, Desktop and in Disk Utility.
Is there anything which needs to be set in System Preference ??
I have the External Hard Disk checkbox checked in Finder Preference, inspite of this I cannot see the Hard drive icon
Please help.

You can try looking in Finder Prefereneces.
Go to the Finder Menu > Prefeences
Look at the sidebar pane. Make sure the Devices box is checked.
Go back to your finder window and make sure that Devices are not hidden. To the right of the Devices work there is a dimly visible show/hide command that is visible only when you have your cursor next to the Devices word.
You can also try unpluggin the drive and unplugging its USB cord then plugging it all back in to try again.

External hard drive suddenly not readable

Help!
I have an external 160GB hard drive (LaCie; Firewire connection) that has suddenly stopped mounting on my desktop. I have used this drive with no problem for ages and with OSX 10.4.
Now I get the message:
'The disk you inserted was not readable by this computer.'
With three options: Initialize; Ignore; Eject.
I have lots of valuable data on this drive that I need to access. What can I do? I have looked at Disk Utility and the disk shows but still will not mount.
Please help!

Yes I have checked System Settings -> Removable Devices - but there is no option for an external hard drive.
And yes it is a ntfs drive, but as I said it worked before couples of updates ago, and just to be sure I checked ntfs-3g - it is installed.
Oh, and I should have said, checking /dev/by-label the drive appear there once turn on, but doesn't get mounted, I use to have a line in the fstab file, but I removed it because it tried to mount it during booting process, and it work anyway.
Any other advice?

Emac won't recognize external hard drive

Had a problem with my emac freezing. After running apple hardware test and repairing disk permissions without any changes I decided to backup eveything and reinstall OSX. Although this solved the problem, I cannot get the emac to recognize the 160GB lacie external hard drive where all the backup files are stored. Any suggestions?

I need to delete a lot of duplicates on iPhoto. I just bought my MacBook Pro and was so excited I downloaded my external hard drive without thinking through the process. I now realize I had my photos doubled up. So I actually have the same library twice.

Hello All!
I am so excited about my new computer and I didn't know that my external hard drive had so many pictures duplicated on it. So I downloaded the entire hard drive. I thought iPhoto was going to be my answer, and now after reading a lot of discussions, it seems I have royally screwed up. Please help me fix this problem. I am a computer novice. An even more Mac novice. I need very simple directions. I would just start over with iPhoto, but I downloaded my digital camera with brand new photos on iPhoto and also downloaded my digital camera software on my new MacBookPro. I am afraid if I "start over" with iPhoto I will lose my digital camera pictures. I bought the Mac to finally get my pictures straight, and look at the mess I have made. I had AVG PC cleanup and used that program last night to delete duplicates from my PC. I also used it to delete duplicates from my external hard drive. I omega. I know, I know, too late huh? But I am teachable. And I now have my external hard drive fixed. But now, my question to the community is how to fix my new Mac, and my iPhoto.
Thanks,

When you say to remove the photos out of the iPhoto folder, then import the clean single copies, I am understanding that the "original" file that the decloner was run against is now the "clean" single copies?
Ok, you've got iPhoto Library that you have imported everything into, you can't delete the iPhoto Library and start over because you have only one copy of some pictures in there, combined with a lot of duplicates.
You want all the duplicates out, but it will take you ages to do it by hand.
What you do is.
1: Right click on the iPhoto Library and "Show Package Contents"
2: You will see a folder called Originals, these are all your original photo's, copy this folder to a external drive someplace, it's your backup.
3: Select the Originals folder again and from the Finder Menu > File > Duplicate.
4: Now you will have a OriginalsCopy folder, move that OriginalsCopy folder onto the desktop area out of the iPhoto Library folder. Close the iPhoto Library folder/window.
5: Download the Decloner software and install it, use it to find all the "real" duplicates, via it's content on the OriginalsCopy folder.
6: From the Finder menu > New Folder, now send the duplicate files to that folder, so all that is left in the OriginalsCopy folder is 1 copy of your pictures, minus all the duplicates which are now in New Folder.
7: Open iPhoto and remove all your pictures in there. The iPhoto Library will update to become empty.
8: Now import the pictures from the OriginalsCopy folder, these will now have only one copy of each picture.
9: Open your New Folder, from the Edit menu > Select All and
10 From the Finder > File Menu > Open With > Preview.
Now you have one copy in your iPhoto Library and the duplicates in a New Folder opened with Preview which you can compare to make sure.
Make as many backups of your pictures as you think you need during this prcess, but eventually you only want 1 picture of all you have in the iPhoto Library.
Some pictures may be the same thing but a little smaller etc., these obviously are not duplicates, and you can weed those out by hand in iPhoto.
Good Luck.

Can't delete files from external hard drive

So here's an interesting problem that I've never run across. I have a Western Digital hard drive plugged in and I was deleting some files off it today when suddenly it started saying that there were some files in use and it couldn't delete those. I hit "Continue" which usually does the trick but it just deleted everything else and left a bunch of folders with these weird empty files in them. So I quit all programs and tried again. Same thing, "Cannot delete, file in use." Tried rebooting both my computer and the external, again "Files in use." Did a google search, followed numerous suggestions, terminal sudo rm -r +file name, a force delete app, secure delete, holding down the option button while deleting... No dice. When I try the sudo rm thing in terminal it tells me that the folder doesn't exist AND that it isn't empty and won't delete it. (I love computers) When I do a right click->Get info on it, it says that I have read-write permissions but that the files are locked but won't let me unlock them (I'm the system administrator). When I look at the files in finder, it says they're actually aliases. What's really weird is that the file names are all messed up and have asian characters and stuff in them. I didn't create these aliases or have files with those characters in them. Soooo... Any suggestions? Cause I've read the threads and tried just about everything. I'm concerned this drive is headed for a crash or maybe just needs to be wiped and then put my stuff back on cause it's gotten errors over time. I don't know, I've never had this happen before and I'm pretty good with computers. If it was a windows computer I'd be doing a scan disk and defrag on it but I don't know how to do that on a mac to an external hard drive. I honestly don't know if this is a hardware or software problem. Any help would be appreciated.

Oh... well this is interesting... disk utility is say that it IS formatted MS-DOS (FAT32). Is that what's causing these errors? This thing has been running with my mac beautifully for years. So do I pull my stuff off, wipe it and reformat it for a mac? Or since it is FAT 32 can I hook it up to a windows computer and fix the problem? Since I had the wrong format, I can delete the files but if I don't fix the format this will keep happening?
