sorry my brain is fried..NAS=?
Sorry, Network Attached Storage. It basically an external hard drive that acts similar to a server, although not as "smart".
do you think the organizer could be the problem? i did have everything nice and orderly then when i moved it off line
I'm not sure what you mean by this? I have found that you should maintain a connection to any externally stored images so that PSE knows where to get the original, full sized image (it stores thumbnail views of the images in it's own database, the theory being that you don't have to have direct connection to the original, but I find this to be unreliable) when you double-click on it.
as soon as i get some extra money i'm getting an extenal harddrive and wondering if i put the photoshop and raw software i have on there also everything would be in one place and just use that for strictly photos. I am afraid with the pse5 continually crashing someday it's going to mess up the whole computer....guessing i just get to an external harddrive like anyother drive , point and click?
Yes, getting to an external drive is the same as any other. Moving your software, as Mickey88 stated, to your external drive is not a good idea. The best strategy is have your software on you C: drive and data (the images) on some other drive (preferably an external device). There a number of reasons why, but I don't think you need to be bogged down with details.
With the state you are now in, I am going to suggest (wait for it ............) to start a new catalog. I know this is a pain but I think you may be in a position that would require more time to recover than to start over.
I suggest you place your image files in their appropriate location using the Windows file manager. Once everything is where you want it, then use PSE to build a new catalog. I usually import (using the File | Get Photos | From Files and Folders option) the images one folder at a time. This gives me a small number of items to have to tag at one time, making it more managable and less stressful for me. I can then stop at any point, continuing later when I feel like it.
One significant point I want to rephrase. I do not move, rename, or otherwise change anything about the original image, including folder names and locations, after I import it into PSE. This just causes me headaches, and I can get those anytime/place, so try not to add to them. If something does happen to a file or folder, use the File | Reconnect option in PSE to attempt to fix it. This may or may not be easy or successful, depending on what happened to the original file.
I wish you success, no matter what route you take to fix your issue.
