Constatly having to rebuild thumbnails in Aperture 2.1.4. Huge Library

I have over 62,000 images in one Aperture Library contained in several projects. One main project is over 48,000 images and requires me to rebuild the thumbnails almost weekly. It takes 12 hours to rebuild. What is wrong? What am I doing wrong. This is the main library that I use and don't know how to stop this. Is there something corrupt? Aperture Library is over 1.5TB

Forgot to mention the Aperture Library is over 1.5TB

Rebuilding Library = Rebuilding Thumbnails?

I have rebuilt my Aperture library since the upgrade. I have not specifically trashed and rebuilt the "ap.thumbnails" for each project. When a library is rebuilt, are the thumbnails for each project rebuilt as well? I had presumed "yes," but now doubt this is true.

Thanks for the quick reply. I am having some issues with Aperture 2.1.4 and Snow Leopard. But I revisited all of my steps since installing the new OS and I may have quit the program while it was building some thumbnails for a project (maaaayyyybeeee). Coincidentally, it is possible I installed the new OS before rebuilding or letting these finish. I also noticed that after the Aperture 2.1.4 upgrade install, the "generate previews" was automatically checked. I never make previews. When I loaded a new project into Aperture 2.1.4, I turned off the preview generation while it started to create them for a new project. I thought the best approach was to delete the previews in the newer project and rebuild the thumbnails in the project I may have interrupted between upgrades.
Though I believe this is grasping at straws since I did a clean install of SL and Aperture and photos on an external and when using Aperture, still had some issues. I have posted on this forum regarding these issues hoping for someone to shed some light....

IPhoto 6 crashed after rebuilding thumbnail cache

I, too, have had trouble with iPhoto 6, but only when I finally clicked "ok" after the endless suggestions to rebuild my thumbnail cache. The result? A loss of all my thumbnails on my eMac. My elaborate structure of albums was there, but each one was empty. I gad to call Apple several times, as the solution seemed to work but didn't at first. I hunted everywhere, as 10,002 photos were seemingly lost, and eventually found the image files in the iPhoto trash. The Apple expert told me that my iPhoto library was probably corrupted (perhaps too simplistic an answer, or were all 10,002 photos somehow corrupted?) so the suggested solution was to rebuild the library after having made a copy of the old library just in case--knowing that the images were actually there in the iPhoto trash. Thank goodness I had just enough space on my hard drive to do this. This crisis occurred the very night before a vacation where I was planning to take a lot of nature photos, so when I returned 10 days later, my first task was to rebuild the library with a whole new album and folder structure. It took two days! Now I am getting the "rebuild your thumbnail cache" instruction again every time I open up iPhoto on my iBook that I use for work and my eMac, and I won't dare do it. Who has a thorough explanation of this problem and has any information on whether or not Apple has encountered this enough to address it? Thanks for weighing in on this.

Christina:
Did you check the file sizes of those files you found in the Trash? If you still have them check their size to see if they are truly the full sized files or just the thumbnails?
Does your current running library have the albums, slideshows, keywords, etc. intact? If so I suggest you try letting iPhoto Library Manager rebuild your library. It will create a new library and a new database file and copy the full sized files from the old library. I believe it creates new thumbnails. That might get you away from that incessant "rebuild thumbnails" message. Here's how:
Using iPhoto Library Manager to Rebuild Your iPhoto Library
Download iPhoto Library Manager and launch.
Click on the Add Library button, navigate to your User/Pictures folder and select your iPhoto Library folder.
Now that the library is listed in the left hand pane of iPLM, click on your library and go to the File->Rebuild Library menu option
In the next window name the new library and select the location you want it to be placed.
Click on the Create button.
Note: It can take some time to create the new library if you have a lot of photos. One user reported that with a library of about 5,000 images it took about 12 hours so plan ahead.
Do you Twango?
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.

Having installed aperture 3 and imported iphoto library (15000 photos) Apertue 3 does not render most of my photos corectly most a blurred pixellated and distorted. Reverting to photo produces perfect results. Any suggestions

Galdaplh,
What do you mean by "reverting to photo"? "Revert" is not a function in Aperture so you must be talking about something else.
If you just performed the import of that many photos, Aperture will take some time to generate thumbnails. You can see if it is doing this sort of thing by {Command}-{Shift}-0 to show the Activity window.
Once Aperture generates all its thumbnails, you will have nearly instantaneous access to much, much better thumbnails than Aperture uses immediately after importing photos.

I am trying to "rebuild" thumbnails

I have been having some problems with iPhoto-----some thumbnails not showing; so I decided to Rebuild Thumbnails. It seems to have "hung." I has been several hours and the blue bar hasn't really moved past 1/2 way in awhile. Should I "stop" the procedure? What will happen? Should I then try to "rebuild" thumbnails again or should I choose "Repair" or "Rebuild" Library or Database?

How big is your Library?
Where is it stored?
Do you have a back up?

Rebuild thumbnail cache

Hi all,
Let me assure you that before posting this question, I read through many of the posts on the same subject. But there were lots of different pieces of advice and I'm not sure which one to use. Also the last post was a few months ago and maybe some new advice has come up.
I'm getting the message to 'Rebuild thumbnail cache' a lot, even though nothing seems to be wrong with the way iPhoto is working. What's the best way to get rid of this message?
I've tried Option + Apple + Launch iPhoto, then selecting all boxes but the 'orphaned photos' one, then rebuilding. That has not stopped the message.
Thanks and regards,
Andrew

Did you go to home/library/caches and delete the iPhoto Folder therein. Then launch iPhoto. It'll take a few moments to launch as it rebuilds the caches.
Do a get info on your HD icon. It'll tell you the capacity and the available space. The reason I ask is that an overfull HD can cause problems like this, but most likely it's just a malformed cache file.

How can I export a comp or pre-comp to another AE project without having to rebuild or make a movie?

Can I export an AE comp or pre-comp to another AE project without having to rebuild or make a movie? In regard to tweaks or timing changes based on that projects' needs.

First, save the project in a different name. Delete out the comps & precomps you neither want nor need. Run AE's reduce project command to remove any unused footage, then save it again. Now you have a simplified project, which you can then import into any AE project you want.
If you like things nice & tidy, don't forget to use the replace layer (Alt-drag, Opt-drag) trick on any duplicated footage, using the footage from the project into which you import the simplified project. The alternative: just leave all the footage alone, and know you can't delete it.

What to do if "rebuild thumbnail caches" is stuck?

How long should it take to "rebuild thumbnail caches?" It has been over 24 hours and after I closed and reopened iPhoto it tried again and still nothing. The wheel just spins. What can I do to bypass this or make it work correctly?

What version of iPhoto?
Backup your iPhoto library, depress the opeion and command keys, launch iPhoto and rebuild your database

Volume structure - having to rebuild daily

Lately I've been having to rebuild my volume structure every morning with TechTool. My hard drive isn't particularly full (30gb available), but just looking for tips on now to resolve this. I've been putting off upgrading to 10.4.x as I figured at this point to wait until 10.5. I also run Onyx daily.
thanks.

What version of TT are you using? If not TT Pro 4.1.2 or higher, your using an incompatible version.
There is absolutely no reason to use Onyx or run maintenance on a daily basis.
Please do the following. If any errors are reported as not reparable then report them verbatim here.
Repairing the Hard Drive and Permissions
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. Then select Disk Utility from the Installer menu (Utilities menu for Tiger.) After DU loads select your hard drive (mfgr.'s ID and drive size) and look in the DU status area for the SMART status. If it doesn't say "Verified" your drive is failing or failed. Otherwise, select your OS X volume from the list on the left, click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported, then quit DU and return to the installer. Now shutdown the computer for a couple of minutes and then restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior (3.0.3 for Tiger) and/or TechTool Pro (4.5.1 for Tiger) to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X. Note that Disk Warrior will not work on Intel Macs.

Oh, oh! Not Again!!!! Rebuild Thumbnails Message...

A few weeks back I began getting frequent Rebuild Thumbnail messages when I launched iPhoto. Eventually, despite the fact that I'd been faithfully rebuilding as instructed, the Last 12 Roll option began to malfunction via displaying rolls with incorrect date sequences. When this occurred I first tried the Rebuild Library option within iPhoto. This didn't rectify matters so I downloaded Library Manager and ran it. Still no luck so I reverted iPhoto back to an earlier Library6.iPhoto and things magically were fixed. Or at least they seemed to be at the time.
Two days ago I began getting the Rebuild Thumbnails message again and I fear I am headed back into difficulties. I have no idea why this is happening and since the security of my photos is extremely important to me I wouldn't mind finding out so that I can keep it from happening again. Anyone have any idea of what might be causing the Rebuild Thumbnails message to display so often?
Also, the other day when I backed up the current Library6.iPhoto I did so by highlighting the file, selecting Duplicate, and then renaming the duplicate created with that day's date... as in 090114Library6copy.iPhoto. I then dragged the file into a folder named iPhotoLibrary6 Backups. When I launched iPhoto the next day it couldn't find the library so I had to use the select library option. Any idea why this would happen?
Last, but not least, after a few months of using iPhoto I would have to say that the application is a good deal more capable than is indicated by the "Mom & Pop Photo Manager" label that is often applied to it. In fact, as a fairly skilled professional photographer whose images are usually pretty decent quality I would have to say that iPhoto is all I need for processing my images about 97.3% of the time. The more seat time I have with the application and the more I get used to using the various tools offered the more amazed I become with the power of this application to create truly stunning images. My one reservation has to do with the issues I've been experiencing with database glitches.
Thanks,
Winston

I love iPhoto for many reasons but it is sensitive to database issues
Therefore backup a lot
I make a daily clone to an external hard drive, just purchased a 1 TB Time Capsule which I have not received yet and use Old Toad's automator script often when I have loading and modifying photos - knock on wood I have not yet had a problem that even required me to use these
I am hoping that Apple improved the database operation in iPhoto '09 - it clearly is too sensitive to disruption and needs improvement
All of that being said you are very unlikely to ever lose any photos with iPhoto - the worst that I've ever seen iPhoto do is lost track of them and fixing that causes yo to lose your edits and keywords and projects - not good but better than losing photos
If you get a good clean library, use Old Toads script religiously and back up often you will not lose anything short of a massive failure of your entire computer

IPhoto6 - after a full reistall of Snow Leopard, iphoto does not display thumbnails. I've restored from time machine, rebuilt the library and run through the rebuild thumbnails function with no success. The files are there, I just get a dotted outline.

iPhoto6 on iMac running SL - after a full reistall of Snow Leopard, iphoto does not display thumbnails. I've restored the library from time machine, rebuilt the library from iPhoto and run through the rebuild thumbnails function with no success. The files are there, I just get a dotted outline instead of the thumbnails. Does anyone have any other ideas on how to restore the thumbnails?

Try the following:
Using iPhoto Library Manager to Rebuild Your iPhoto Library
Download iPhoto Library Manager and launch.
Click on the Add Library button, navigate to your Home/Pictures folder and select your iPhoto Library folder.
Now that the library is listed in the left hand pane of iPLM, click on your library and go to the File ➙ Rebuild Library menu option
In the next window name the new library and select the location you want it to be placed.
Click on the Create button.
Note: This creates a new library based on the LIbraryData.xml file in the library and will recover Events, Albums, keywords, titles and comments but not books, calendars or slideshows. The original library will be left untouched for further attempts at fixing the problem or in case the rebuilt library is not satisfactory.

Rebuilding database in Aperture

Rebuilding database in Aperture causes "Recovered Folder" to appear in project, even with Aperture & Mac trashes empty. Tried deleting "recovered" images and emptying trashes then rebuilding but it has the same effect, another Recovered Folder.

While I agree "repair" should -- as Apple recommends -- precede "rebuild", I have not in my experience found any reason to not run "rebuild" when needed, and have never seen an ill effects. Have you?
I have. It was related to a bug I'd discovered a few years ago. Rebuilding the database made it worse, and afterward I was warned that rebuilding could be destructive, and that it should only be done as a last resort. So be careful.

Why frequent prompts to rebuild thumbnail caches?

Why does iPhoto 6 continually prompt me to rebuild my thumbnail caches? It takes me less than one minute to do it, but I can't understand why it is necessary to do this so often.
Bob

When you launch iPhoto the app runs various checks on itself to assess the database and so on.
He fact that you are continually being prompted to do this rebuild is of some concern. It suggests that the app is finding a glitch on the DB and is not able to repair it.
First off, back up.
IF you want to: Download iPhoto Library Manager and use its rebuild function. This will create a new library based on data in the albumdata.xml file. Not everything will be brought over - no slideshows, books or calendars, for instance - but it should get all your albums and keywords back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one.

Can you build a new version of an exe without having to rebuild its installer afterwards?

I'm currently testing a LabVIEW-built exe on a PC without LabVIEW installed. Each time I go back to the development PC to fix a bug / change something, and then rebuild the executable, it seems I also have to rebuild its installer which takes a significant amount of time.
Is there a way to rebuild an executable without having to rebuild its installer? Or a way to tell the installer it doesn't need to be completely rebuilt, but rather just needs to look at the new executable?
After writing this out, I've realised there probably isn't a way to do it, but it's worth a shot.
Christian.
Solved!

In my opinion, it's just easier to create installers.
Yes, in your circumstance it would be. For me, I only have to worry about internal customers, so I am the only one that does the install; therefore, I don't have to worry so much about the details of the installation.

HELP@!!@ Accidently declined to rebuild thumbnails in iPhoto!!!!

I opened iPhoto and a message popped up that said something to the effect of "for best performance rebuild your thumbnail cache" there were two options: rebuild now and ok. I accidentally clicked ok and the message went away. I tried quitting iPhoto and re-opening it to get the message to pop up again and it did not, I also tried restarting my computer. Does anyone know how to manually rebuild the thumbnails or if there is somewhere in the toolbar to do so?
any help would rock my world
thanks

Launch iPhoto while depressing the option (alt) and command (apple) keys - select the rebuild thumbnails option for the resutling dialogue
