External Drive and Duplicate files

I moved my images to an external drive through LR5.2. Everything is working great except there are 6 files (organized by date) that LR says already exist on the external drive. They are not on the external drive and I can't seem to get LR to move them. Everything is in date order, so it's easy to see thay they are not there. Any ideas on how to move these files? BTW this has happened with more than one batch move... now I have a few dates from each move that remain on my computer leaving holes in the file dates on the external drive.
I'm using Mavericks (10.9) on MacBook Pro.

Hi,
SElect the dublicate images and press ctrl-s (cmd-s on mac?). This saves you developments as xmp files. Now sync the target folder. Perhapst Lr states the dublicate images as missing - remove than.
DO the same with the source folder.
IF you removed the images from one of your folder, everything is ok.
IF not remove then from the target folder and move than.

External drives and dmg files mount fine, but won't show on desktop

Recently purchased a new Mac Mini 2.3 ghz i5 with OSX Lion. Everything is updated, repaired permissions from the check disk utility.
Still my firewire drive, and any DMG files from software I'm looking to install are not showing up on the desktop. They mount fine, I can write to them, see them on the Finder left siderbar, share them on my intranet at home and use Back to Mac and Screen Sharing without any problems.
Anyone have an idea why this peculiar flaw is occuring? Is it a "feature" of Lion?

Much better: I was in the same shoes once as you

External Hard drive and dmg files not mounting

External Hard drive and dmg files suddenly not mounting. Im running Mavericks on 27" iMac. Anyone have a fix or has anyone else suddenly had this problem? There was a Mavericks update a few weeks ago, but things were fine until today. This is weird. Ive checked in disk utility and can see one of my two external HD's, the one that I back up. But not even this will mount. Ive tried repairing HD thinking it was damaged but now see that all my ext hd's suddenly dont mount. Ive tried several mac restarts.

Solved the problem. My external HD is a WD (My Book Studio). I needed to install updated driver manager and this fixed it:

Import is just a word for copying photos from the phone to a computer and not that different than what I do in Windows -- although I haven't compared the speed on a large number of photos. If you are importing and using iPhoto, you might try doing it with Image Capture which will allow you to copy them directly to an external drive. It may be faster than doing it to iPhoto but I haven't compared the speed. Instructions from http://support.apple.com/kb/HT4083 are shown below.
Connect the iOS device to the computer.
If Image Capture does not open automatically, you can navigate to your Applications folder and open Image Capture from there.
Choose the location to which you'd like to import pictures.
Click Options.
Click the Options tab if it isn't already selected.
Enable the option "Delete items from camera after downloading".
Note: Deleting photos after importing helps to reduce Camera Roll size, and it improves backup and restore times. You may choose Keep Photos if you wish to import the photos to additional computers.
Click OK.
Click Download All.

External hard drive and viewing files

I have recently upgraded to a 15 inch 2014 Macbook Pro (OS X Yosmite Version 10.10) and imported all my old iMovie files from time machine without any major issues. I'm now running iMovie 10.0.6 and I have since had to move them to a external hard drive and want to delete them off my computers hard drive to free up space, but my problem is this......the files appear under the external drive in iMovie, but under Finder I can't physically see the actual files on the hard drive. Just a film strip icon with what I named the external drive and some old files. Anyone else had this problem or any suggestions?

IIn iMovie 10.0.6 all Events And projects are saved in one iMovie file!!!!! So no chance to see the created events and projects in old filed and folder structure which is a big **** regarding backups as the one file can be TB big although only a small piece in it has changed.

Until I get it fixed Is there a way to copy the files off of an Apple Install DVD onto an external drive and then do theinstall from the external drive? It's ILife 11 if that makes a difference.

Thanks.

Adding an SSD is not a simple endeavour like adding additional memory or adding another hard drive to a Mac Pro. That's probably why the option is only offered as an option at the time of purchase. Even if your Apple store was willing to install the necessary parts you will probably be paying for 1-2 hours of labor plus the cost of purchasing the necessary service parts (SSD, bracket, cables, etc) which I suspect will make the upgrade cost much higher than what it costs to add the SSD option when purchasing a new system.
I use my system for business and need it to work reliably. Even though I'm fairly handy with tools I would not be willing to risk damaging my system and voiding my warranty by opening my system and removing the logic board and several other parts in order to squeeze in an SSD option and attach the appropriate cables and brackets. I'm also not prepared to deal with the hassles of explaining why my system has unauthorized parts installed in the event I experience issues and need to make use of my Apple warranty. My time is valuable, so I would probably investigate external storage options, or if I needed the speed of an SSD, I would consider selling my existing system and then purchase a new system configured with an SSD.
If you haven't already done so I suggest doing a search on 'iMac SSD installation' to see what's involved. It might help you understand why the SSD option is not offered post purchase.

Taking the plunge - external drive and exclamation points

Okay...
I have cried for help on this forum before about the somewhat common problem of iTunes 7 having a strange relationship with music on my external drive. The drive in question is a Lacie 250 GB Firewire drive.
A few months ago, out of the blue, one day I opened iTunes to find a sea of exclamation points. Though all the music I had added after a particular date was there, most of the music I had added prior to that was tagged with the exclamation. When I'd try to play one of these songs, iTunes would say it could not be found, though I could manually locate it and things would work fine. I tried a few fixes recommended on this forum by well-meaning but misguided people that resulted in a few sets of duplicate playlists but no fix to the problem. Then, one day, out of the blue again...it started working fine.
I don't even recall having restarted the computer. iTunes had just fixed the problem somehow.
Well, now the problem is back, and I've dealt with it for about a month. But I'm not convinced that it will just go away this time. So, even if I destroy my painstakingly cultivated hundreds of playlists, ratings, play history and comprehensive information (artwork, composer, etc.), I am determined to fix this problem without manually locating over 10,000 songs.
I am posting my attempts here as a record that will hopefully help those struggling with this problem in the future. Though I would welcome any and all comments or questions, I have frankly come to expect very little assistance or even the willingness to assist from this forum (that is to say, I imagine my unresolved question will languish for awhile as a monologue until I either fix the problem or die).
The first thing I will do (after doing a final backup, of course) is to determine whether it makes a difference if an updated version of my iTunes library file and .xml are in the Music folder (on my hard drive) or in my Musica folder (on the external drive). The latest edition of the file is currently on the external drive.
So, here we go...

Dual 1GHz G4, 1G RAM, 80G HD Mac OS X (10.4.9) iPod (1st Gen), iPod Shuffle (1st Gen), iPod Mini, External HD

Well, I've made quite a mess of things. So I have 14,000 songs. Most were added years ago. Looking at the date added in correlation with the exclamation points, it seems as though iTunes forgot the location of most of the songs added before 5/9/06. Mind you, iTunes worked fine (with the exception of doing this whole thing once before) until about a month ago. So, in May 2007, iTunes forgot most of what happened before 5/9/06.
(For reference purposes, the gap seems to exist between two songs I downloaded. "Help Me, Ronda" by the Beach Boys is the last song with an exclamation point in the date added list (see two exceptions below). "Proud Mary" by Ike & Tina Turner, on the other hand, is exclamation point free and only a couple of songs added after "Proud Mary" have exclamation points. They are:
Freedom, by Richie Havens, added 6/3/06.
Slow Free Bird, by Geesekey, added 12/17/06, a song I made in Garageband.
Now, don't let me give you the impression that there is a solid wall of exclamation points up to "Help Me, Rhonda." Maybe about every 10/20 songs, there is a song with no exclamation point that plays fine. Following Jase's lead before (his advice to another user), I have investigated some of these songs that work fine, but can't find any reason why these work and others don't (any difference in the iTunes Library.xml, files created with/without track number, etc.).
So, here's what happened in the past couple of days: I dragged my "iTunes Music" folder (located in my "Musica" folder on the external drive) into the iTunes source list). Most everything was duplicated, with the new songs playing just fine but lacking ratings and play history. Also, the new songs were not included on any playlists.
What I did next was poorly executed. I sorted iTunes by the Date Added and selected the first few thousand (roughly, A-J; seeing them according to the Date Added reveal that they weren't added in exactly a linear fashion). I hit the delete button and selected "Remove", but I then told iTunes to "Move to Trash." What I should have done, I imagine, is told iTunes to "Keep Files". So, my A-J songs are now deleted off the External Drive and gone (though I have backup DVDs generated by the iTunes "Back up to Disc" feature).
What should I do next? is the pressing question. Should I rip everything out and start from scratch with my backup discs? I guess the question I would have with that approach is this: if I restore from backup discs made three months ago, will I still have all my playlists, ratings and play history as they were when I made the backup? If that's the case, that'd be fine with me...I just want to make sure that's what will happen. Also, I have a backup of my iTunes Library file before I've done all this crazy stuff of the past few days, so if that enters into the equation, let me know.
Otherwise, let me address your comments, Jase.
Anyway, here's a question. Can you export your
playlists, even though they're made up of songs with
exclamation marks? If so, you could try exporting one
of them as an XML file. Then import it--you'll
probably wind up with duplicates (playlists, not
songs). Does the newly imported playlist play, or
does it still have the exclamation mark problem? I
wouldn't know what to expect, but it might be worth a
try.
My playlists themselves are all still the same as they were (though there are exclamation marks all over the place). From what I can tell, they look fine when exported to an .xml (the music folder seems to have the correct path). When I import it, it's the same deal: exclamation points at the same places.
If your playlists are exportable, you might want to
export them to XML files, just so you'll have those
little databases of them. Then, if worse came to
worse and you had to give up on your current Library
file and reload your Music folder into a new library,
at least there's a chance you could import your
playlists and not have to build them again from
scratch (assuming nothing has changed in terms of the
organization of your Music folder).
I'm not willing to export every playlist, because I have hundreds and it would just take too long. Is there a way to export all or a lot of playlists at once? Anyway, I figured that my playlist data was stored somehow in the iTunes Library file, so I felt I had a backup already. I could be wrong about this, though, as I really don't understand much about the iTunes Library file and .xml and the like.
Can you drag songs that have exclamation marks into a
playlist? Somehow, I doubt it. But if you can, you
could use new playlists to make a record of some
information that you might want to save if you had to
start all over again with a new Library.
Believe it or not, I can add songs with an exclamation point into playlists and they're added just fine (though, they still have the exclamation point). How this works is: I can't drag and drop them into a playlist. However, I can control-click and select "Add to Playlist" and it works. There's another mystery for you.
Have you looked at your iTunes Library.xml file --
specifically at the location information for
individual songs -- to see if the location
information exactly matches the information you see
in the Finder? I have found mismatches when
investigating some exclamation marked files. I didn't
know how that happened, and I didn't know what to
about it, but it was intriguing to see evidence of
some iTunes mischief.
Is the iTunes feature to start music file names with
the track number turned on? To my mind, fewer missing
song file problems occur when this is on.
Yes and yes. Based on what you told others, I have looked at the .xml of some of the problem songs and the working ones and could find no difference, but I didn't really know what I was supposed to be looking for. I also use the Add Track Number feature and always have.
If you still have the 28,000 songs in your Library
and want to go back to the 14,000, you could sort all
your songs by Date Added and delete the ones you
added on June 21. Or, if you saved a copy of your
iTunes Library file before you dragged your iTunes
Music folder into the library, you could just throw
out the more recent Library file and reinstitute the
back-up copy.
I probably should have done the latter (just restore the backup of the iTunes Library file). Oh well...
Some advice for future experiments. Try them with a
small sample if possible unless you're absolutely
sure they will work the way you want them to. For
example, drag one album in your Music folder into
iTunes rather than the whole Music folder.
This is a great idea. I wish I would have checked my sample more closely or done more tests before I plunged off the cliff.
Back up your iTunes Library file, as well as your
Music folder. (You might already do this.)
Check.
Those are a few things to think about. They probably
will not be helpful. Like I said, I don't think there
are clear answers to this problem. The best I can
wish for you is that iTunes will magically fix the
problem, like it did once before. Then, maybe there
are some preventive measures you can take.
Since iTunes did fix it once before, I would not
throw your current iTunes Library file away, no
matter what. If you decide to start a new library so
that you can actually listen to your music, rename
this Library file and keep it around, since it has a
lot of your metadata in it. You can try it every now
and then and see if iTunes spontaneously revives it.
Okay, I will post what I do next, provided that I don't hear any compelling advice and make my own decision (though I should be even more gun-shy after my recent blunders).

I'd love some help trying to figure out why my 2008 MacBook no longer recognizes my external drive and now is not downloading photos from my iphone....?

After many years of having no problems at all on my Macbook, I recently figured I should finally upgrade my OS. I did that about three weeks ago, updating to Snow Leopard (10.6.8). I used Time Machine at least once after the OS upgrade but now Time Machine no longer recognizes the external drive I have used for all these years to back up. The MacBook does not "see" it. (Disk Utility does however.) The computer then also stopped recognizing another La Cie back-up that I have and now... my iPhone cannot download photos? Yikes.
I have, of course, shut down numerous times, used different cables (that worked for some) and the two USB drives. I even used a firewire. Nothing worked. I also tried to "Repair disk" on Disk Utility. It didn't work either, giving me an error (that I didn't save, sorry).
I read many other discussions on the file format of the external drive and of course I'd be happy to reformat the external drives--however, it is obviously a tad nerve-wracking to reformat drives before having an accessible back-up. Suggestions? I do not remember what file format they have but am pretty sure it's not the Mac file system someone mentioned. The drives are a 2009 WD "My Passport Elite" and La Cie 2007 d2 Quadra,
In terms of other hardware available, we do have another MacBook Air but it has started rejecting both drives as well (without the Snow Leopard upgrade). We have an old Dell but it wouldn't have the disk space to help out much.
Any thoughts on the process involved would be welcome. Any ideas on the iPhone rejection would be helpful as well! It is a 30gig iPhone 4 that has 20 or so gigs free (not clear as iTunes says that there are abour 18 Gigs on the phone but 24 free gigs? I may be bad at math but that's 40 gigs...).
I am checking out iCloud but apparently there are only 55 gigs available?
Will be glad to hear any thoughts. Thanks!

Good afternoon Lyssa,
Phew. First of all, thanks in advance...these blogs are always comforting help!
So, to answer your questions: For the age of the hard drive.Well, I added memory a couple of years ago (RAM and hard drive). Being a mom leads me to eat up a fair amount of gigs with photos of my kids and, in fact, I think I entirely replaced the original drive, so it is a couple years younger than 2008 since I did that in March 2010. If there is some way to verify that (whether or not I replaced the entire drive), I'm all ears. I have 311 Gigs free, so it is not a space issue. I verified the startup disk on Disk Utilityand nothing showed up.
Question 1- What formats...
The La Cie is format Windows NT Filesystem 3G ....At the time that I bought it I was still using a PC as well as a Mac and was told by afriend to use this format...
The WD is Mac OS Extended (Journaled). I again tried to repair the WD last night and this is the error message: "Error: DiskUtility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files."
Also, Time Machine tried again to back-up and gave me this error: "Files can't becopied onto the backup disk because it appears to be 'read only'. You may needto repair or reformat the disk using Disk Utility. If the disk can't berepaired, you must use a different disk for backups. Open Time Machinepreferences to select a different backup disk."
Question 2. Other cables...
I used two other cables with the WD and that didn't change anything.
Question 3... Fire Wire from the La Cie
Yes, I used the Firewire cable from the La Cie and it is indeed present, though still not visible in Finder. Since it is not Mac OSExtended I know that I can't use Time Machine with it.
So, in summary...
I can plug in the La Cie and it is functional on the MacBook, visible on Disk Utility but not visible in Finder. The WD drive is not visible and not functional. So we can think it is indeed the WD that is not working.... Also, the iphone photos did, in the end, get downloaded, so it is not something more general.
Causes...
I forgot to mention that there is a "lost+found" file on the WD which apparently points to a UNIX /OS issue?
Some kind of "insurance"?....
I'm curious about how people avoid this kind of issue. You just regularly replace back-up drives and hard drives before problems come up? Time Machine is great and saves many of us from disasters, however, knowing that your Time Machine back-ups are vulnerable makes the whole system insecure. No way to have alarms ring before the drive goes out?
As for ways ahead...
It seems that I ought to be able to copy off of the WD to the MacBook then erase it and reformat it and start over again. However, I haven’t been able to see its contents except on random occasions. If you have any ideas on how to copy the Time Machineback-ups from the WD, again, I'm all ears!

I redirected iTunes to an external drive and moved my iTunes library and folder, but my hard drive is still low on space. How can I be sure that my music is all on the external HD ONLY, especially with the new iCloud technology?

I redirected iTunes to an external drive and moved my iTunes library and folder, but my hard drive is still low on space. How can I be sure that my music is all on the external HD ONLY, especially with the new iCloud technology? It doesn't look like I created any more space by doing this, AND I totally lost all my iTunes playlists. I'm not sure if because I added old library materials manually if this messed up my playlists, or if the new location is just not reading my moved library. In any case, I followed step by step instructions and found a few holes and thought I'd just "figure it out" but I guess I'm not as smart as I thought since I'm still scratching my head many hours later.
Thanks for any support ;-)

Quick answer if you use iTunes' default preferences settings: Copy the entire iTunes folder (and in doing so all its subfolders and files) intact to the other drive. Open iTunes and immediately hold down the option (alt) key (shift on Windows) so you get a prompt to select a library, then guide it to the 'iTunes Library.itl' file in the moved iTunes folder.
If this is to a new computer and you put the copied iTunes folder in the default location of Macintosh HD > Users > *User Name* > Music then you don't even need to start with the option key held down, iTunes will automatically look for it there. (Make sure there isn't anything already in the iTunes folder there that you want to keep since you will be replacing it with the one you are moving.)

I have my iTunes library on external drive and can access from any PC. However I cannot access from new MacBokk Air.

My iTunes library is on an external drive and been using it on two PCs with no problem.
Now that I got a new MacBook Air I want to access the same iTunes library from the external drive and keep all the library and media on that external drive.
When I try to change to another iTunes library by hitting "option" with iTunes and select the library on the external hard drive I get the following message:
"The iTunes library file is locked, on a locked disk, or you do noy have write permission for this file."
I have read many posts in which many suggest to go to the library or media file on the PC and right click to make sure the read only tab is not checked.
I uncheked the read only tab and gave full permission to all the iTunes files and folders.
The unusual part is that I can use this external drive on many PCs that I have tried with no problem at all.
I just select a different library, which is on my external hard drive and everything works, play lists and everything.
However, when I try it on a MAC i get the message stated above:
What can I do to be able to access my External iTunes library from new MacBook Air while keeping everything on the external drive like I can on PCs?
I am running latest version of iTunes and Mavericks.
Please advise.

Using an external drive with shared files (iPhoto, iTunes), attached to a Time Capsule, can the contents of the external drive be backed-up to the internal Time Capsule drive? Perhaps a RAID1 mirror to a partition?

Using an external drive with shared files (iPhoto, iTunes), attached to a Time Capsule, can the contents of the external drive be backed-up to the internal Time Capsule drive? Perhaps a RAID1 mirror to a partitioned Time Capsule? I understand that the Time Machine (software) cannot backup a networked drive (the external) and that Time Capsule (the router/wireless hard drive) does not have its own backup software... so it won't backup the connected drive. What I would like is an alternate solution for having an automated backup of a networked drive. A 2TB Time Capsule has more than enough space for Time Machine backups of my family of Macbooks, so I had hoped to mirror a 500GB external drive (with shared media files) to a portion of the Time Capsule internal hard drive. I assume this would require a partition of the Time Capsule drive. If not, would the sparse file from the various computers being backed up need to be copied to the external drive as part of the RAID1 setup? This seems like overkill for the Time Machine backup, but it would cover the media files.

The complexity with this idea is the software has to run from a Mac computer on your network.. so you need a Mac turned on, probably most of the day.
It isn't possible to partition the TC although you can create a image area.
The software would have to copy the material, that means all files to be copied, go from USB drive, back to the Mac, then back to the TC, and written to the drive. In other words you have just added Network congestion, although a proper incremental backup type software will not actually use a lot of capacity.
Finally it will be slow.. network drives are slower than internal drives. Well USB connected drive is much slower than the same drive connected directly to the computer.. and if the drive is connected directly to a computer it can be shared with the network.

Read carefully the speed of the USB drive plugged into the TC.

How do I move my iTunes Library to an external drive and retain everything?

I'm sure this is a common [stupid] question, but I couldn't find a clear answer and I want to be sure I'm doing it correctly.
To clarify; I want to move/relocate my iTunes Library folder to an external drive (FW800 two-disk RAID1) to free up my system drive and have a backup. Do I redirect iTunes to the new location and use File>Library>Consolidate Library, or, can I just move or copy the 'iTunes' folder to the external drive and then change the iTunes 'music folder location' to the new location? Will this now save all subsequent imported/purchased music, movies,,..etc to the external drive and retain all my library details?

My late 2006 iMac stopped finding my back up drive. I've tried rebooting but no good. Tried unplugging the external drive and rebooting. How do I tell my computer to find the external 500 GB dive that is plugged into it?

I have a Western Digital 500 gig external hardrive that I have been using successfully with Time Machine to back up my files. A few weeks ago I noticed that the external drive light was ON but not moving back and forth indicating that it was working. The light was now simply ON but not moving. So I checked and sure enough Time Machine didn''t "see" it anymore. When I tried to fix it, the drive is no longer on the list. Nothing is on the list. The external drive is not showing anywhere, including the desktop. And when I tried to switch Time Machine on the list is empty and it wants to "look" at airport for a wi-fi type peripheral. Help! How do I get the iMac to realize it has an external drive plugged into it? I don't even know why it worked when I first got it or why it stopped working. I only know that Time Machine doesn't have it listed.

Open disk utility and check the external drive and repair it. If that didn't fix the problem or if you are unable to see the drive in disk utility then the drive could be bad.
