Files disappear when selected.

I have several MP4 and M4V files on an external MyBook Studio 500 GB hard drive. All but 4 show a small preview. These remaining 4 show the QuickTime logo, but when I select these files, they disappear. If I then click away and then back to this folder, these 4 re-appear. If I use QuickTime to open them, Open is in gray. Finder will not allow me to get information about the file. I figure the file is corrupt, but how can I be sure? Is there a way to recover/rebuild these files?

ITunes playlist songs disappear when selected to play

iTunes playlist songs disappear when selected to play - ie double-clicked, or clicked once and then play selected. The song doesn't play although there is a brief 'flash' of something at the top of the screen where you would normally see the song details mwhile playing.
The song is not deleted from the library but is still missing from the playlist when iTunes is restarted.

Ron Kozinski wrote:
I just recently upgraded to iTunes 9 and have found that some songs (18 of 750) will no longer play. I get a couple different error messages, one saying iTunes cannot find the URL for the song and another saying iTunes cannot find the file for the song. I hate to pay for these songs again since I already purchased them from the iTunes store, but I don not know what other options are available. Has anyone had this problem and if so, is there a way to fix these songs?
Usually that occurs when the file, or one of its containing folders, is moved, renamed, or deleted. If you remember doing one of those things, see if you can put it back the way it was. Otherwise, search on your hard drive for the song file, and re-add it to your library.

iphoto and itunes files disappeared when i upgraded to os mavericks. How can i retrieve these files? Time machine is not opening my backup files on an external Lacie HD.

Apple keeps books for a short time (used to be 40 days. I've not seen a recent time frame)
What version did you have?
Books do nor exist except in the iPhoto database so you can not "find" a book vista TM. You restore a previous library (be sure NOT to overwrite your current library) and switch to it

An issue whereby Photoshop .PSD files disappear when saved to a network file share

It has been reported and reproduced by Support, an issue whereby Photoshop .PSD files disappear when they’re saved to a network file share.
Upon initial investigations Support have observed the following behaviour when saving a Photoshop file.
The document is initially saved as a new file on the file share.
The original .PSD file is deleted on the file share.
The newly created file is renamed to the same name as the original file.
An issue often arises when steps 1 and 2 complete however step 3 fails. When a file is reported by users as having disappeared, the new file created in step 1 can be renamed from .00_ to the original *.PSD file name on the server as the *.00_ files are normally hidden by the desktop operating system. This allows people to see and open the file from both PC’s and MAC’s using AFP and SMB protocols.
A related issue often reported by users is that they receive an error message “Could not save as” when trying to save a .PSD file. Troubleshooting the issue confirms that the user is able to save the file if they perform a “Save As” operation in Photoshop.
From the reported problems and observations there is clearly an issue with how Photoshop performs a file save operation further exacerbated by the fact the process doesn’t fail safely.

Sounds like you're hitting one of the known MacOS filesystem bugs - worst when working with SMB volumes.
Apple knows about this, and we are pursuing workarounds to the OS bugs.
Yeah, if you value your files, don't save directly to servers, especially on MacOS.

Files disappear when creating a new folder

I'm new to mac....got a macbook this week. I'm in Iraq so I have very limited access to anything. No internet for my mac at the moment...so I can't update even if there are ones. I assume I have the currenct version of everything though. The question...
While switching over my files I decided to reorganize them. I'm working on my external HD and creating many new folders for all my files. On numerous occasions now (4) I have created a new file the standard way...right click>new>file...then named it. On these occasions I have done this it has renamed the previous file I had worked in (even though it was not selected) and then the contents of the file disappeared. This leaves me with the new file I created and another identical file of the same name...now with nothing in it. Some of my files I have backed up, but the last one deleted many videos that I didn't. Happens randomly at no particular time. If I select the file and view its contents often it will briefly change its name back to the original name, but still nothing in it. Then next selection of anything will switch it back. Have not been able to fine the files anywhere. Tired of losing my files. Any ideas??? Thanks.

Hi Craig and Welcome to Apple Discussions....
First of all, thank you for all you are doing. It's so appreciated! Just be safe and come home soon.
Now... I have a feeling your external hard drive is the culprit. Read here:
Changing the names of items
You can easily change the name of a file, folder, or disk on your computer.
IMPORTANT: To avoid problems using Mac OS X or applications on your computer, don't move or change the names of folders that came with your system (such as the Library folder or your home). You should also not change the names of applications or items associated with specific applications. If you accidentally change the name of an installed item and you experience problems, you can change the name back.
Locate the item you want to rename on your desktop or in a Finder window.
Click the item to select it, then click the name. The name is highlighted and you will be able to edit it.
Type the new name and press Return.
Some document names have a file extension, such as ".txt" or ".jpg." If you change the name of a file and delete the extension, some applications may no longer recognize the file. To ensure the file can be recognized by the application that created it, change only the part of the name that comes before the extension, or open the file using the appropriate application, then save the file with a new name.
You cannot change the name of an item in the Finder window's sidebar. You must locate the item on your desktop or in a Finder window to highlight and change the name.
And more here:
Getting information about files and folders
You can view and modify information about files, applications, and volumes in the Info window. This information can include:
Comments that Spotlight can search on
Who can view and modify the item.
The applications that can open it.
Metadata that describes a file's contents and how it was created. For example, a photo's Info window may contain the picture's dimensions, exposure time, and the make and model of the camera.
To see information for one or more items, select the items and choose File > Get Info. An Info window opens for each selected item.
To see a summary of information about several items, select the items then hold down the Control key as you choose File > Get Summary Info. A window summarizes information on all selected items, including their total size.
To see information about each item as you select it, select one of the items then hold down the Option key as you choose File > Show Inspector. An Inspector window displays information on the selected item. When you select another item, the Inspector's contents are replaced with information on that item.
I realize that's a lot to digest and your time might be limited. This is something that only takes a few minutes and might help immediately.
Go to MacintoshHD/Applications/Utilities and locae Disk Utility. Launch DU, select MacintoshHD in the panel on the left and then click: Repair Disk Permissions. Depending on the size of your drive, it should only take a few minutes. When it's finished, Quit Disk Utility from the Menu.
Here's how to find out exactly which Mac OS you are running. Click the Apple logo top left of your screen then click, About This Mac. A pane will open. Just under "Mac OS X" will be the version number. ie., 10.4.x
Reboot your MacBook and see if this helps.... I'm retired and have time... if you need one on one help e-mail me: [email protected]

Why do windows source directory files disappear when their folder is added to iTunes?

I just got a new Windows 8 computer and installed iTunes. I then copied all of my music to my new computer from the old one into a similar \data\music directory organized by artist and album.
On the old computer (XP)when I add a folder from \data\music to itunes the source album music files remain inplace.
On the new computer (W8) when I add a folder from \data\music to itunes the source album music files disappear.
However, although the album directory is empty, the "parent MUSIC directory" hasn't changed in size. Is iTunes encrypting the source files? Itunes Help does have anything on this happening.
How do I access my source files if I want to do something with them?
This is scary stuff. Luckily I still have a copy on my old computer.
Any clarification on this would really be appreciated.
Thanks,

Here are typical layouts for the iTunes folders:
iTunes 11 also adds a Home Videos folder...
Your library is obviously in the newer layout, the designated media folder (red outline) is C:\Data\Music and the option Keep iTunes Media folder organized is enabled, so music goes in C:\Data\Music\Music\<Artist>\<Album> etc.
If you're interested you could probably "normaiize" your library with a few carefully chosen steps...

Why do my pls files disappear when doubleclicked?

Someone asked me how to make an alias of a streaming radio station that they could just click, have it open iTunes and play.
While experimenting I found I could drag the radio station off the iTunes playlist to the desktop and it would create a URL. Doubleclicking the URL usually opened a browser, went to the site and downloaded a .pls file to the desktop. Doubleclicking that file opened iTunes and started playing the station.
Fine, I thought, I'll just rename the .pls file and use that as an alias to quickly get to the station. But alas, the .pls file disappears from the desktop once clicked, even if renamed and/or put into a folder.
I explained what I did to the person who originally asked and they were able to rename the files and not have them disappear on their Mac like mine did. Both of us are using 10.4.11.
Can anyone shed some light on this?

Try showing the import options and make sure the crop option you want to use is one that is not grayed out.

How can one make the drop down list of bookmarks disappear when selecting an item?

File names in finder disappear when selected

When I select files or folders in an open window in Finder, the names disappear, but the icon still shows. Scrolling or moving the window will cause them to reappear. Also, None of the toolbox windows show information (like font name or point size) in Adobe apps until you click in and select all. Type something in, click enter, and new text disappears.
I've deleted Finder prefs, deleted font caches, repaired permissions, reinstalled LucidaGrande.dfont - no effect. Help!

Help with JTable - content of cell disappears when selected

Hello,
I have a jTable and I have created a custom cell renderer. It does what it's supposed to do (which is set the background color of all cells with null or "" value to red - as an indication to the user that b4 proceeding he/she has to fill in this cells). The problem is that when I select a red cell, it becomes white and the text value it contains disappears. When I double click I can start typing in a new value.
I would appreciate any hint why this happens? Ideally I would like the cell to keep its color when clicked or double-clicked and its value, and only when i'm done editing its content and it's not null or empty string to become white.
I'm including majority of my code (some automatically generated code from Netbeans is not included).
Thank you very much,
Laura

Ideally I would like the cell to keep its color when clicked or double-clicked Not sure why is changes color when you click on the cell.
But when you double click the editor is invoked, which is a JTextField and its background is white by default.
The code you posted doesn't help because its not executable.
If you need further help then you need to create a [Short, Self Contained, Compilable and Executable, Example Program (SSCCE)|http://homepage1.nifty.com/algafield/sscce.html], that demonstrates the incorrect behaviour.
And don't post NetBeans generated code, because we don't use IDE to write GUI code.
Also, why did you create a custom TableModel. The DefaultTableModel will store your data for you.

Objects in InDesign files disappear when exported to PDF (CS5.5)

I have some text that was created to outlines, filled and has a drop shadow applied. When I export the document to pdf, part of the text (the fill) disappears, and all I get is the drop shadow. I tried changing to a non-spot color, I tried removing all attributes, and nothing seems to work! I also tried copying that artwork to the clipboard and pasting it into an Illustrator file (says it is too big to fit the pasteboard, which I verified sizes - and it should fit. I tried copying the paths and pasting them in Photoshop as a smart object... no luck either. What am I missing? Thanks in advance for any help!

FYI - in the "Adobe InDesign Component Infirmation" dialogue box I learned all kinds of info - are you looking for something in particular? I learned that the document was created in InDesign version 7.0.4.553 (which is what I think I was using before I updated my InDesign earlier today)
There aren't particular obvious signs, no.
Generally at this point the right way to track this down is to work with a copy of the document, and delete pages or objects in the document until you find the cause of the problem. Then look at it closely, perhaps look at the IDML file, or make it available so we can look at it.
It sounds like you have a workaround, but if you have time, it might worth trying to find the real problem.

Files disappear when played - ARGH!

I had several dvds converted to play on my ipod. The external hard drive is where I stored them, since my laptop doesn't have the space. itunes advanced properties was set-up for the external drive's use. I opened the H drive movies with itunes and noticed after they had played in itunes, they disappeared from the original folder that I put them in! The "movies" are now somewhere within the itunes library (likely renamed so I'll never find them manually) now but I have no idea why they were moved from the original folder or where the insane program put the files. I CANNOT find the movies to watch it through another program that is not so insanely complicated to use- the movies are now gone!
I had to buy a 250Gb external hard drive to manage the music, since there's not enough room on the computer's hard drive. For some reason, itunes decided to start using my C drive one day, instead of the H drive, originally designated as MY choice (maybe I opened itunes one day without the external hd on?). I noticed the exclamation points on the music and panic!! I started trying to backup music, for fear of losing it. I re-designated the H drive again and did some hacking to backup the songs saved off the ipod and into another backup- then imported the backup folder and lost all play lists as a result. I'm NOW afraid to syc.
How can you backup your files if you don't have control over which drive you designated as the sync or even where the files are placed? Why does itunes remove files from folders when you play them? I've never been so confused by any software in my life as I have with itunes. I'm not able to enjoy the music comfortably and am always in fear of losing what I have. I've turned into a music manager instead of a music lover. The program has a mind of it's own...totally alien to what I want it to do. ARGH! No way I'm ever going to update the software again either. I cannot manage the learning curve on what I've got now, after over a year.

Writing to Multiple Data Files Only When selected?

I am building a system that is measuring the CO2 content of 12 vessels but only 1 CO2 gas analyzer. So, my system has a series of valves that only lets one valve open at time so that only one vessel is being measured at a time. What I would like to is have a measurement file for each vessel so I don't have to worry about determining which data came from each vessel. Also, I only want to write measurements to each file whenever its corresponding valve is turned on. The third thing I would like to do is to be able to read the data file and plot the trend data as the test is running. These test will run for 14 days. So what would you recommend to do this? Would you recommend using a Write to Measurement File Express VI, Write to Spreadsheet, Write to Text File, Write to XML?
Requirment Summary
1) File for each vessel
2) Only write data to file when corresponding valve is selected
3) Ability to read the data files and plot the trend data over time for the 14-day test.
I am using a Consumer/Producer design with two consumer loops one for processing and writing the data and the other to control a pump for a waterbath that was made inhouse.
Thanks!

This is such an open ended question...but I will give some advice.
If you plan on reading and writing to a file, dont use the write to measurement, you want to use the open/create/replace and close file functions. The particular file you write to can be either of those listed, but the text file will require all numeric values to be changed to strings, which is just more overhead to take care of. If I could recommend a type, it would be datalog files. They are great to organize your data. I don't see any reason to use XML. Do you want to be able to open and review this data later? Do Post-Analysis in Excel? Maybe write to spreadsheet is what you are looking for then.
Also, how fast are you gathering data? At high speed, maybe you want to use binary files. Downside is that you wouldn't be able to easily open the file for viewing outside of LabVIEW. For a 14 day test, make sure you have enough resources for your sampling rate, as any ASCII files, such as .txt, can grow large very fast depending on how you sample and how many digits you store.
For example, if we only store a 5 digit sample from one channel at 10 hz for 14 days:
5bytes/sample*10Samples/s*60s/min*60min/hour*24hour/day*14days = 60,480,000 bytes, or 60MB.
Are you wanting to show all of this data on a chart at once, and update live? This will use a lot of resources(RAM), but should be doable. I would obviously have to know more about your engineering requirements to make any more suggestions, just wanted to give you a feel for the ups and downs of some of your options. If you have the LabVIEW DSC module, then Citadel would be great for logging this data for you.

Why are NEF files desaturating when selected in CS3 Bridge?

File disappears when trying to export with "share" in FCP X...

I have FCP 10.1.3 running on a macbook pro running 10.9.4; attached to an external 8 tb drive with over 6 tb of free space.
When I try to export a project using "share," the file will start to save to my destination, but then just disappear at exactly the 50% mark. I've shared previous versions of the same file with no problem, and I have enough space to hold the file. I've tried restarting the app and the computer; I tried saving to an external drive and to my hard drive; the file will simply disappear from either destination at 50%.

This is weird. Before we proceed with other possible tests, did you try this with just one project, or with other as well? If just this one, create a new library, a new small test project and export that. Does it work? If it does, then the problem may me in the specific project or library.
A few other ideas:
1) Delete application preferences (almost always the first thing to try, as corrupt preferences have been known to cause strange malfunctions). Hold down the command and option keys while starting the application and confirm the deletion of preferences when asked.
Note: deleting preferences does not delete the application nor your media and libraries
2) Open the Console application (it is in /Applications/Utilities) and look for messages that appear around the time the export fails.
3) Try running the program from a pristine new user account and see if it exports correctly a small project there
