Installing iTunes to alternate internal hard drive?

Question

Cliff Notes Version:
Can someone help me re-install iTunes on an alternate internal drive (a drive other than C)?
I have just removed iTunes and all components from my PC and now need to reinstall.
You can read the details below but ultimately I want to install all things Apple on my E drive as opposed to my C drive.
If you do read the details, I chose option 3 at the bottom as opposed to trying to fix existing errors or files.
I tried moving both the library file and the database file as instructed but you can see the error messages below.
What I am looking to do is do the original install on the E drive to avoid moving anything as that did not work the last time.
I am not looking to save any files or playlists...I can repopulate those fairly easily. I just want this set up right out of the gate.
Any advice greatly appreciated.
Original Posting on Another Board:
I originally tried to move itunes the library & database and got the these errors
- iTunes Library cannot be saved . There is not enough memory
- the iPhone Doug's iPhone cannot be synced. An unknown error has occured (-23)
My System:
Windows 7 64 bit
C drive = 96Gb SSD that is used for program files only. I want to move both the library and database (ie all Apple software) off of here.
iTunes 10.7.0.21
System has 8Tb of memory over several hard drives (music, photos, etc...). iTunes will only manage the music part of my media
Of these drives, about 1.5 Tb is music. Of that 1Tb is a copy (FLAC) of all my CD's. The other 1/2 Tb is digital music I have downloaded.
E: = 1 Tb drive for digital music (mp3 files) It is less than 20% full
H: = 1 Tb drive containing a FLAC copy of my CD collection
Bonjour was/is disabled as it had been causing other issues with the system (edit - is has now been uninstalled with the remainder of the Apple software)
I wanted to move itunes (both the library and database files) is to keep the SSD at a lower capacity. Obviously the library files alone would have over-ran the drive, but I am not sure how large the database file gets, so to be safe I moved it too. Here are the steps I took:
First I moved the library (at the point it was moved it only had 3 mps cd's in it).
1. Edit>Pref>Advanced
2. Checked only the Keep iTunes Media Folder Organized (I do not want a second copy of all my music in the library.
3. Clicked CHANGE button and chose E:/Music folder (the same drive I have my digital files on and only 20% full.
4. File>Library>Organize Library>Consolidate Files>OK
I then moved the iTunes Database:
1. Shut down iTunes
2. Copied the iTunes folder to the new location (also E:/Music)
3. Restarted iTunes while holding the shift key and chose the library.
Finally, I moved in all the digital files from the E drive (File>add Folder to Library). This appeared to work and all my MP3 files appeared in iTunes.
The problem started when I attempted to sync my iPhone. I should note that my music library has been recently rebuilt as I lost everything on a previous drive (music, iTunes, etc...). So, when I attempted to sync the phone for the first time since re-installing/rebuilding everything, I got an error message: this iPhone is already synced to another Library. And that if I continued with the sync, I would lose all the files on the iPhone. I was ok with that as I had the files in the new/rebuilt iTunes. Also checked was the button to let me check the files I wanted to sync as iTunes is much larger in size than my phone. At that point I tried to select several files to sync with the phone and got the error messages listed at the top.
So, I have a few questions:
1. Can anyone tell me what the error messages mean? The first about not having enough size makes no sense. The drive that iTunes was moved to was only 20% full at the time on a 1Tb drive. Even if I had chosen to keep a copy of the music in iTunes (which I did not) it would have still only been 40% full including the iTunes Library file. I have no idea why I got this message.
2. Just how large will the iTunes database get. I know this is subject to how much it "manages" but assuming 3-4 Tb of music, photos, etc... how large will this file grow? On my SSD Windows is taking up more than 25% of the drive. I could leave this on the SSD provided it will remain fairly small and just move the library but thought it would be just as easier to move everything.
3. Would I be better off completely installing iTunes and re-installing it on the alternate E drive as opposed to the default C (SSD) drive? This is what I have choosen to do, so far have uninstalled iTunes and now have questions regarding re-installing on an alternate drive (see very top)
Any help is greatly appreciated!

Answer 1

turingtest2 - thanks for the info. Have some questions:
1. Already used 3rd party software to backup all the music from my phone (about 99% ripped from cd or purchased elsewhere than iTunes. So, I really need to just get any data (contacts, etc...) and the apps purchased backed up. I assume doing steps 3-6 from the Recover Your iTunes Library link you sent will do this?
2. From what you sent, just my database file will be about 20Mb on a 96Mb drive. That is precisely why I want to move the database as well as the library off the C drive.
3. I currently have no library as I deleted all things Apple earlier today. What I do have is 2 drives that contain music, an E drive for music downloaded and an H drive for music ripped from CD's. So I don't currently have a library to know if it's working. The process you describe is a split process with the library database on one drive and the media folder on another drive. In my case I do want to "move" the entire iTunes folder to another drive but an internal drive. And as opposed to moving the files, is there a way to simply install them that way when downloading a new copy of iTunes (rather than installing then moving the files)?
Also, in the Make a Split Library Portable document you linked, it sawy that any media files outside of  the media folder will need to be consolidated. Since I am starting from scratch, I assume there will be no files there yet to consloidate. Or would this be the files I backed up and restored (apps, data,etc...) in step 2?
As for manipulations you mention, are any of these necessary in my case if I am not moving a library but rather creating a new library on a different drive? I assume once the
Or, in short, how can I simply install (or move) the entire iTunes folder to my E drive and then compile the library with music? And if you don't mind, could you be pretty detailed on moving/installing both the library database and the media folder on the new drive? I got confused about renaming, root drives, etc...
Or am I overthinking this and it is as simple as downloading iTunes (to the C drive)> copying the iTunes Media folder (and all contents)>pasting that folder in my E drive> going back and deleting the original iTunes Media folder in the C drive> then re-opening iTunes +shift key to point to the new iTunes Media folder on the E drive?
Thanks again
