Is it normal for files to go missing from an external hard drive?
I've posted about this issue before but for slightly different reasons. I'm about to buy a new hard drive (the old one is full), probably I'll go for the exact same model, and I want to know if the problem I had described here has happened to Mac users.
I use a Retina MBP with OS X 10.8.4 that also runs Windows 8 on boot camp. At the same time I have an Acer Aspire and what I used to do is download movies onto my external drive with my MBP in Mac - I would also rename the files in Mac - and then connect the drive to my Acer so I could access the movies there.
One day I noticed that some of the files, after I had renamed and moved them to a new folder on the same partition, had gone missing. As I described in my old thread, it was a weird problem because those "missing" files would appear in Windows but not in Mac. But even in Windows when you could see the folders, they were all corrupted as the system indicated to me - the folders couldn't be accessed and the movies wouldn't play.
Thankfully I haven't had this issue again but then I haven't dared to move any of my movies to a new folder either. Not since that incident. I'm pretty sure that I wouldn't have lost those movies and had them corrupted if I had kept them in their original location. Is it normal for files to go missing or be corrupted when you move them back and forth, especially when you use an external drive with one OS (Mac) and then switch to another (Windows)? I've always wondered if this was an issue. I never formatted the drive when I got it, I just plugged it in and used it. That was before I bought my MBP.
I also was unable to delete those corrupted files/folders. Windows wouldn't let me and in Mac, they didn't even show up. I solved this eventually by using Disk Utility to repair the drive.
Now I'm fine with letting my files stay put if that's what it takes to keep them safe and secure, but I'd be more comfortable if I can understand what went wrong all those months ago.
The hard drive I have is this one from Samsung.
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), then guide it to the iTunes Library.itl file in the moved iTunes folder.
If 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.)
Longer answers if for any reason you do not think all library files are inside your iTunes folder (changed preferences settings at some point):
iTunes: How to move [or copy] your music [library] to a new computer [or another drive] - http://support.apple.com/kb/HT4527 - a somewhat bewildering and not always easily understandable set of options.
For the record there's this reference for iTunes 11 but it really doesn't strike me as having the specifics you need. iTunes 11 for Mac: Move your library to another computer - http://support.apple.com/kb/PH12168
2011 ilounge article: Transferring your iTunes library - http://www.ilounge.com/index.php/articles/comments/moving-your-itunes-library-to -a-new-hard-drive/ - An article with good background information (similar to the links above), particularly if you are not sure your media files are all grouped for quick answer above. Unfortunately under the single term "transferring library" it describes two very different moves; relocating just your media (not really transferring your library and not recommended unless you really need this configuration), and relocating media+database (really your whole "library"). Make sure you understand the difference before electing to move only media.

Any suggestions for running an iTunes library from an external hard drive on two computers?
I have two Mac computers: an iMac and a MacBook Air. My iMac has 1TB of storage space (plenty enough for my 200+gigs of music) but my MacBook Air only has 250gigs of storage space. I know I can access all of the music from my iMac on my MBA with HomeSharing. But that doesn't work when I take my MBA out of the house for work. I was going to switch over my iTunes library to an external HD but I don't know if I can access the library on the hard drive from my MBA, when the main library is on my iMac.
Any suggestions as to how to get two different computers to access an iTunes library from an external hard drive?
Thanks.I am confused as to what you had or have where and when. The bottom line is, your library (for the standard user) is everything in the iTunes folder. As far as iTunes' organization and display is concerned, your library is a file called "iTunes Library.itl" which points to all the other host of files and folders normally in the iTunes folder which all work together.

If you kept everything together in one place then you need to put the whole iTunes folder on the drive where you want it, start iTunes while holding down the option key and guide it to that .itl file. If things were split up and you had media on the external and the rest of the library on the internal you need to get them back to exactly where they were before. If you can't find that iTunes folder holding the critical .itl file anywhere then you have a bunch of media tracks and no organization and will need to rebuild the organization from ground level. -
I'm attempting to migrate files, address book, maile, etc to my new Mac Mini using an external hard drive and Migration assistant. I followed the instructions on using Migration Assistant to do this but Migration Assistant is not seeing the external drive, which is displayed on my desktop
I've been chasing this problem all afternoon. I had to reformat my internal drive on my MBP and reinstall Mountain Lion Start up assistant wouldn't see my extrnal drive with the Time Machine files on it. After many tries, I skipped the restore there and let the system boot. I could see my external drive from Finder and the files looked OK. I was told to use Migration Assistant and it had the same problem.
I saw a hint on one of these posts that the icon that you see and is label Macintosh HD is actually your backup disk and it is telling you that it has a copy of your internal Macintosh HD. I went ahead and told it to continue and it started to restore my apps, settings, and documents. It's been going for a couple of hours, and is close to being done. I expect to see my old system restored when it is finished.
Wish that Apple would put some type of note that it is seeing the backup. That is most confusing and seems to be a problem for lots of users.
It's been a month or so since your post Did your get it to work? -
I moved some time machine backup files from an external USB hard drive to the trash. Tried secure empty trash. It counts 74,003 items, then just sits there. The external hard drive window shows it's empty, but the info pane says it only has 50G of memory left. I left the secure empty trash on over night. It did nothing. Ideas?
Thanks,
RonRelaunch the Finder, then from the Finder menu bar, select
Finder ▹ Preferences ▹ Advanced
and uncheck the box marked Empty Trash securely. Try again to empty the Trash. -
I imported files from an external hard drive to Itunes on a new computer. they imported & play fine, but the ratings & playlists are gone & i am unable to update any info. I found a file name playlist on old drive & imported now most files are missing! Help!
Can you locate the iTunes Library.itl file on the old drive? Ideally you would have simply copied over the entire iTunes folder structure from <User's Music> on the old computer into <User's Music> on the new one to transfer the library will all playlists, ratings, play counts etc. intact.

I can't copy iTunes media files from one external hard drive to another.
Hi, I am running the latest iTunes and Mavericks software on my MacBook Pro. My iTunes library is stored on an external Seagate 2tb hard drive and it is almost full. I want to transfer the files to a WD Elements 3tb external hard drive and have made that new volume the destination folder for my iTunes library. However, even though I have enabled read/write on both volumes and made the iTunes media folders on both shared folders, I can't copy all the files from the Seagate drive to the WD drive. It comes up with an error message that says "The operation can't be completed because an unexpected error occurred (error code -8058)". I can transfer files from my MacBook hard drive to the new volume, but can't copy files from the old Seagate volume to my MacBook hard drive; it makes the "boing" sound that indicates it is copying but nothing transfers. Files that won't copy include all music files, some video files and all podcast files. Some transferred with no problem. Any ideas out there?
Hi Limnos, thanks very much for your reply.
both external drives came preformatted for Windows but I erased each and reformatted them for Mac before using them.
i made the destination folder on the new WD drive the new iTunes folder using Advanced preferences in iTunes.
my original iTunes folder on the first drive contained all my iTunes files, as that, also, was the destination folder that was linked via Advanced preferences.
If I download new content now with the new drive attached, iTunes has no trouble finding where to place the files.
in Preferences I have both boxes checked (copy files" and "organize") that deal with copying iTunes files.
When I first attempted to copy all iTunes files from one media folder to the other on the external drives, I just did a drag and drop of the whole iTunes media folder from one to the other while both were mounted on my desktop. It started copying immediately with no problems, but as it progressed it started skipping files, each time displaying the error message I reported earlier. that included my entire Music folder. When I open, for example, a season folder that contains files that would not copy, eg, Modern Family Season 5, the episodes that won't copy are there and visible but any attempt to drag and drop them into the correct folder on the new drive results in the error message. There is no pattern to it; it will choose some episodes from some seasons but not others, and no music at all.
when I look at the "missing" files in iTunes they have the small exclamation mark that indicates the file is missing, but when I locate it through iTunes it doesn't copy the file on the old external drive to the new one. It just plays it having found the file on the old drive.
originally I had to make the iTunes folder on the old drive into a shared folder using the Get info window after either a software upgrade or an OS upgrade (I can't remember which, it was several years ago). For some reason the upgrade changed the preferences of that folder to a Read Only folder and after researching the problem found the only way to keep using the drive was to make the folder a shared one. I can't remember why and I apologise for that but it was a long time ago.; I can tell you that at the time it was necessary.
thanks again for your time; I have a good working knowledge of iTunes and Macs in general so I truly believe I have done everything according to how it should be done,, but clearly I've done something wrong! -
Importing .mxf Files from an external hard drive...
Any advice or tips would be greatly appreciated. My problem comes close to others discussed, but I haven't been able to find a duplicate post. And I apologize for the length; I just want to give you as much info. as possible (I also put details in my signature) to help you help me.
I shot a short film using Panasonic's HVX200 camera, filming in HD 720p/24p, and downloaded each P2 card through a PC laptop into a LaCie Brick external hard drive. I was originally planning on editing the footage with Adobe Premiere Pro 2.0, but became frustrated with how much trouble it was having handling the .mxf files. Assured by Apple salespeople that FCP 5 would have no problem importing the footage from an external hard drive, I purchased the computer described in my signature.
Now I know that FCP/Apple only supports importing footage from the P2 card directly, and not from an external hard drive. A representative from ProMax.com was able to help me out, however. First, he had me copy the footage files onto my Mac internal drive from the external hard drive. Then, he had me select IMPORT -> PANASONIC P2. Then, I was to highlight the CONTENTS folder and import away. And it worked... sort of.
There are two major problems: 1) During this transfer, not all of the footage is making it across. I import it, and then get the much-talked about "one or more P2 clips failed to import; probable incomplete or corrupt clips" warning. After checking the original video folder on the internal hard drive and comparing it to the number of clips FCP imported, I learned that I had lost around 20 clips/video files at one point. Other shooting day transfers worked completely smoothly with all of the files imported (we split up the footage by shooting day, without touching or changing the CONTENTS folders). So, some transfers work and some don't. And 2) When I try to import the files from our 4th day of shooting, I get a "Selected path does not contain a P2 volume." Nothing is imported.
So, that's my situation, and I'm getting very desperate. I know that I'm not doing things in the Apple-supported way, but I'm really hoping there's still someway to successfully get the files from the external hard drive into FCP completely. It seems to work some of the time.
Final notes: When importing, I make sure to import the entire CONTENTS folder. There is never a LASTCLIP.TXT file listed under it in the window, but some of the days of footage have transferred perfectly, so I'm hoping that's not a dealbreaker. If it is, isn't there some way to rebuild a lastclip.txt file? I don't even know if that's the issue. And one last note: In most of my folders, the "CLIP" folder has a number of files in it. In the 4th day's footage that I can't import at all, I noticed that the CLIP folder is empty. And on the days where FCP isn't importing all the files (like I mentioned above), there isn't a CLIP file for every single VIDEO file. Could this be the main problem? Along this line, is there a way to somehow put the footage on the external hard drive back through a p2 card and then into the Mac?
Okay, I'll stop typing. Thank you so, so much for any help.

PowerMac G5 (Dual 2.3 GHz) Mac OS X (10.4.6) Quicktime 7.1.1 - Final Cut Pro 5.1 - Aforementioned External Hard Drive: LaCie Brick (FAT 32 based)
PowerMac G5 Mac OS X (10.4.6)The problem didn't turn out to be as complicated as I had thought. The process I described above ended up working fine, and I'll explain how. And this is a cool workaround, because the AppleCare helpers told me that they didn't think it would work (FCP P2 import is only supported straight from the P2 card/viewer or the camera).
I hooked up my external hard drive to the Power Mac G5, and copied the files and folders onto my internal scratch disk. Then, I opened FCP and chose IMPORT -> Panasonic P2. I chose the "CONTENTS" folder for each day's filming, and imported them in, no problems. There was no visible "lastclip.txt" file shown (under the "CONTENTS" folder or anywhere else), but this didn't seem to cause any problems.
The reason that not all of the footage was bring imported (the aforementioned "one or more P2 clips failed..." warning) was because we were missing clip files (in the CLIP folder) corresponding to certain video files (in the VIDEO folder). Luckily, we had just forgotten to transfer all of them from the original external hard drive, and once we transfered them completely, FCP could read all the video files. FCP needs a clip file for every video file in order to make it work (that's why our aforementioned "Day 4" could not be read; we hadn't copied all of the clip files over with the video files).
Even after we did this, we STILL were getting the "one or more P2 clips..." warning for our Day 5. After taking a look at all the folders, we figured out that there were still more files in the VIDEO folder than in the CLIP folder, even after we transferred them all over. Finally, we figured out what had happened. For some reason, some of the audio files for some of the clips had been included in the VIDEO folder for our Day 5. There is no way we did this accidentally; somehow, the HVX200 placed some of the audio files into both the VIDEO and AUDIO folders. And FCP was trying to read those as video files, and therefore couldn't find the corresponding clips in the CLIP folder. After making sure that those audio files were also in the AUDIO folder, we simply deleted them from the VIDEO folder and stopped getting the "failed to import" warning.
Final thing to share: If we had actually been unable to find the corresponding clip files in our original external hard drive, we had also found a potential solution (that we didn't end up needing to try). You can record from FCP back onto the P2 card, in the hopes that the clip files would be regenerated when you re-import it into FCP. I received a PDF file about this process, and I'm not sure how to put it up on the page here. If interested in this described process (which, again, I can't fully vouch for), feel free to email me at [email protected] and I can forward it to you.
Hope this helps.

My Windows 7 PC just had to be reformatted, and I have retrieved all of my files from an external hard drive. About half of my iTunes library is working fine, the other half pop up the error statement "original file cannot be located." If they haven't come off my external drive, where are they?
This happens if the file is no longer where iTunes expects to find it. Possible causes are that you or some third party tool has moved, renamed or deleted the file, or that the drive it lives on has had a change of drive letter. It is also possible that iTunes has changed from expecting the files to be in the pre-iTunes 9 layout to post-iTunes 9 layout,or vice-versa, and so is looking in slightly the wrong place.
Select a track with an exclamation mark, use Ctrl-I to get info, then cancel when asked to try to locate the track. Look on the summary tab for the location that iTunes thinks the file should be. Now take a look around your hard drive(s). Hopefully you can locate the track in question. If a section of your library has simply been moved, or a drive letter has changed, it should be possible to reverse the actions.
Alternatively, as long as you can find a location holding the missing files, then you should be able to use my FindTracks script to reconnect them to iTunes .

I have an iMac purchased in May 2011. OSX Lion 10.7.3. I deleted backup file from the external hard drive which operates from Time Machine.
Now, the trash can will not empty some of the files deleted from the backup harddrive.
The trash contains-- File folder: "Core Services" which contains a locked file: "boot.efi".
It will not delete.
How do I get the trash can empty of these files?Yes, the Old Master file has a folder for each year where I find all photos from that specific year. I am attaching a screen shot of the file.
In the meantime i have managed to download all photos (it did not download any video files though in mpg, avi, 3gp, m4v,mp4 and mov format) to a new iphoto library. Unfortunately the photos are quite mixed and often doubled up. I ma considering to purchase iphoto library which checks all duplicates in iphoto. this will save me a lot of time. What do you think? -
I cannot copy my doc and photos and videos from one external hard drive to a second external hard drive -- both plugged in to my MacBook Air -- I get Error 8062 and the copying (which seemed to be going on for 10 minutes) stops and nothing gets copied.
As any Macbook Air owner knows, there is SO LITTLE storage capacity on the computer that you have to back up big files onto an external hard drive to avoid getting the other annoying error that says you have no more memory/storage capacity/whatever the proper term is, and you cannot use the computer.
Backstory: Before this error cropped up, I had backed up lots of files to an external drive and then removed them from my computer. But then the external hard drive got corrupted and I could not access my entire photo library. Had to pay $850 to Kroll Ontrack to recover those files. I have now bought 2 new external 1 Terrabyte hard drives as protection against another such disaster. BUT I cannot copy the files from the first hard drive where all my reovered files now sit, to another backup hard drive.
Feeling vulnerable. Please help.
SusaninNYFrom the menu bar, select
▹ System Preferences ▹ Energy Saver ▹ Power Adapter
and uncheck the box labeled Put the hard disk(s) to sleep when possible, if it's checked.
If the drive has more than one interface (USB, FireWire, Thunderbolt, eSATA), try one of the other interfaces.
Check that the data cable is securely inserted at both ends.
Try a different cable.
If you're connecting the drive through a hub, connect it directly to a built-in port on the Mac.
If you're connecting it directly, try a different port.
Disconnect all other devices on the bus, or as many as possible.
Test the drive with another Mac. Test another drive with this Mac.
If the drive is bus-powered, but has an AC adapter, connect the adapter.
Start up in Safe Mode and test.
If the drive doesn't work under any of the above conditions, and if another drive does work with the same Mac, then the drive has failed. You may be able to salvage the mechanism by removing it from the enclosure and installing it in another one, or in a drive dock. -
I recently reset my computer and copy my music from an external hard drive to my itunes library. When I click on a song to play i get an error message that says " the song could not be used because the original file could not be found". But when I have my external hard drive plug in the song will play with no problem. What do I need to do to play my music without having the external harddrive plug in ???????? Please help
Because the location for each song in your library is on your hard drive. If the hard drive isn't there, how can iTunes play it?
You'll have to move/copy the music from your hard drive to your computer's hard drive.
Basically, EASIEST way to do all this, if you don't care about your play counts, etc...
-Delete EVERYTHING from iTunes, so that your library is now empty.
-Go to "Advanced" inside of the "Preferences" window, found in the "Edit" drop-down. You can also access Preferences by pressing Ctrl+, (Press Ctrl and the comma key)
-Change your iTunes Media Folder Location to something simple, but on your computer. I use C:/iTunes. Make sure "Keep iTunes Media Folder Organized" and "Copy files to...." are both checked. You can close Preferences now.
-Now, drag and drop your music from your hard drive into your iTunes library. iTunes will automatically add the music to your library, as you would expect, and also creates a copy of each file to place into that iTunes Media Folder you just created.
Shouldn't have any more problems... -
I cannot find videos (not movies) that i have transferred to my macbook pro from an external hard drive, these files used to be on my windows PC. Photos and a few of the videos came over but i am missing the majority of the videos. Help please!!! I have tried omnidisksweeper with no success in finding them.

Why can't I copy files from my external hard drive - error code -50.
I sm trying to back up an external hard drive to a network drive. Some files copy but not all;. SOmetimes a folder seems to have copied but then I see that most of the files inside have not. And sometimes I just get 'An unexpected error has occurred'. Error code - 50.
I need to have a back up copy of the files on this hard drive. How can I stop this happening and copy files properly and securely?
The external hard drive is a LaCie bought from Apple, share formatted FAT32.
The network drive is a WD MyBookLIve Duo which WD tell me should work equally well with any operating system.
Please advise. I need to archive a security copy of this data urgently

Is there a possibility to recover erased files from an external hard drive that was reformatted by the Time Machine?
Basics of File Recovery
Files in Trash
If you simply put files in the Trash you can restore them by opening the Trash (left-click on the Trash icon) and drag the files from the Trash to your Desktop or other desired location. OS X also provides a short-cut to undo the last item moved to the Trash -press COMMAND-Z.
If you empty the Trash the files are gone. If a program does an immediate delete rather than moving files to the Trash, then the files are gone. Recovery is possible but you must not allow any additional writes to the hard drive - shut it down. When files are deleted only the directory entries, not the files themselves, is modified. The space occupied by the files has been returned to the system as available for storage, but the files are still on the drive. Writing to the drive will then eventually overwrite the space once occupied by the deleted files in which case the files are lost permanently. Also if you save a file over an existing file of the same name, then the old file is overwritten and cannot be recovered.
General File Recovery
If you stop using the drive it's possible to recover deleted files that have not been overwritten by using recovery software such as Data Rescue II, File Salvage or TechTool Pro. Each of the preceding come on bootable CDs to enable usage without risk of writing more data to the hard drive. Two free alternatives are Disk Drill and TestDisk. Look for them and demos at MacUpdate or CNET Downloads.
The longer the hard drive remains in use and data are written to it, the greater the risk your deleted files will be overwritten.
Also visit The XLab FAQs and read the FAQ on Data Recovery. -
I downloaded Mavericks but can't get past the install; it thinks my hard drive is reserved for Time Machine. I have an external hard drive but dis-connected that before download.
I have Time Machine turned off.Check to see if you have a file name Backups.backupdb on the disk drive.
If the installer sees such a file it assumes that the disk drive is being used by Time Machine.
