Why can't I install Tiger on an external drive?ne is

I have a MacBook Pro running Leopard. For reasons I won't get into, I need to have a Tiger boot volume. I have any of 3 external drives I could install it on (one is a FireWire hard drive, one is a USB, and one is an iPod). However, the Tiger installer won't recognize any as valid drives. On the window where you pick the drive to install, they all have a red "!" on them and on mouseover it says something like "Tiger cannot be installed on this drive. Your Mac cannot boot from this drive."
Why?
Could it be because I'm using the Mac OS X install disk that came with my MacBook Pro when I bought it in 2006 and not a separate Tiger installation CD?

Limnos is onto the correct path, mostly. Install DVDs for Intel Macs require an external drive to be partitioned with the GUID partition table in order to install onto that drive. If the drive is formatted with the Apple Partition Map (APM), or something else, the OS X installer will not install onto the drive. Also, the volume must be formatted as Mac OS Extended (Journaled).
You can check the partition scheme of the drive with Disk Utility. Be sure to select the Drive (size/model# in the list), not the Volume (whatever name you gave the drive), and look at the bottom right - will either be GUID Partition Table or Apple Partition Map.
Note that it is possible to get the OS onto an APM-partitioned drive, formatted as Mac OS Extended (Journaled), and successfully boot an Intel Mac, but the OS must be cloned onto the external drive (e.g. with SuperDuper or Carbon Copy Cloner) from an Intel Mac - it cannot be installed directly from the Tiger install DVDs. I have a LaCie external drive with APM partitioning, and I can boot my MBP in Tiger from that drive (and my wife's PB from it as well, since the bootable clone of her machine is on a separate partition of the drive).
Having said that, since you have upgraded to Leopard, I suspect you no longer have an MBP running Tiger to use as the source for that bootable clone. So, you'd need use Disk Utility erase one of your external drives (FireWire is best for an external boot disk, although Intel Macs will boot via USB as well - it's just slower), and set it up with the GUID Partition Table (one partition, or more if you like), Mac OS Extended (Journaled) format, then the Install DVD should recognize the drive as a valid target for the Tiger installation.
Hope this helps...

Why can iTunes NOT FIND songs on an EXTERNAL DRIVE

I've read many posts regarding the use of external drives for iTunes data storage. Here's my situation:
I've just restored my computer to it's factory settings, then installed iTunes 9.2.1.5 My iTunes consists of songs only and they reside on an external drive following this path: E:\iTunes Music\(artist)\(album)\(song[s])
iTunes Music, artist name, and album name are all folders. The songs appear in numeric order (01, 02, etc.), and are individual MPEG files.
I have tried changing the iTunes Media Folder location to: E:\iTunes Music (by following: Edit-Preferences-Advanced) Indeed, I have attempted all possible folder paths...right down to individual songs...nothing works. iTunes simply does not see the folder(s)/songs. What's up?
The frustrating thing is that this very same external drive worked just fine before this whole affair! ??? What am I missing? Please provide a detailed answer. Many of us out here would like to know the secret.

You'd have had more luck if you'd moved your library files out to your external drive as well as the media. That way, when you'd reinstalled all you would have needed to do was use SHIFT-start iTunes and point it at the library on the external.
Next time you reinstall Windows backup the entire *Documents and Settings* or Users folders from the C:\ drive so that after the rebuild you can restore anything you discover you still want from your old profile.
Better yet do these backups before something goes wrong, say once a month. The following tool is great for general backups of any specifc set of folders, not just iTunes.
<hr>
*Fast backup for iTunes library (Windows Only)*
Grab SyncToy 2.1, a free tool from MS. This can be used to copy your entire iTunes library (& other important data folders) onto another hard drive or network share. You can then use SyncToy periodically to synchronise or echo your library to the backup. A preview will show which files need to be updated giving you a chance to spot unexpected changes and during the run only the new or updated files will be copied saving lots of time. And if your media is all organised below the main iTunes folder then you should also be able to open the backup library on any system running the same version of iTunes.

I can't seem to find the audio driver that the notebook likes. It installs fine, but then goes back to found new hardware and can't install it.

Hi:
You first neeed to install the MS UAA driver before installing the audio driver.
Install the chipset driver first if you haven't done so already. Reboot.

Why can't I install Snow Leopard on my videos hard drive?

I have a Mac Pro with four hard drives. Lion is on the primary drive but I need Snow Leopard for a legacy app. My plan is to install Snow Leopard on a hard drive that I use for video projects, and then restart from that drive when I need to use the old app. The problem is that the Snow Leopard installation disk says that it can't install onto the videos hard drive unless I partition the hard drive, which will erase all the data. Why can't it install onto the videos hard drive? There's no operating system on that hard drive. The hard drive has folders for Final Cut Express Projects, iMovie Events, iMovie Projects, DVDs movies I've ripped, a folder of music, and an iDVD project. What do I need to remove to enable installing Snow Leopard?

If I understand what you are saying you have a drive with "stuff" already on it and you want to install a version of OSX on to it while still retaining that "stuff". If that's what you want to do you cannot do that mainly because there's already "stuff" on that drive.
The only way you can do this is to either of the following:
a. Copy the "stuff" off that drive to another drive. Install the OS. Copy the "stuff" back on to the newly created boot drive.
b. Copy the "stuff" off that drive on to another drive. Partition the drive into at least 2 partitions; one for the boot and one for the "stuff". Install the OS into one of the partitions. Copy the "stuff" back to the other partition.
Either way, if you want to use that disk for a boot disk, you got to get that "stuff" out of the way to do the OSX install on to that disk.

Can I install Linux on an external drive?

I'm kinda curious about something. If I boot up off an external firewire drive at boot time and I have previously partitioned it into 2 partitions (techtool or iPartition) is it possible to install a Intel Linux distro on the 2nd partitition?
When I go to boot from that external drive will the Linux installed boot loader allow me to select OSX or Linux to actually boot from?
Even better can I just install Linux on this external drive in the only partition?
I'm only looking to experiment with a Linux distro and I don't want to use Parallels anymore so I'm wondering if I can use an external drive to do so.
TIA,
Peter

Here is an indirect answer. I know you can using Paralles, not sure about the other way though.

Trying to run Tiger on an external drive for Pro Tools LE on a new iMac...

okay, i am buying an mbox2 that runs pro tools LE (which, as we all know, is not yet supported by leopard), and i am also buying an iMac 20-inch 2.0GHz Intel Core 2 Duo, ATI Radeon HD 2400 XT with 128MB memory (with leopard pre-installed). i've read in some forums that people have been formatting an external firewire 800 drive an installing tiger on it so as to use it as the startup disc when running pro tools LE. i basically have two questions regarding this:
1) does anyone think this would not work? why? and
2) will i be able to install tiger on the external drive using my macbook pro osx install disc that came with my laptop? (it's a tiger 10.4.8 install disc, but it does say "macbook pro" on it, so i'm wondering if apple doesn't allow you to install these on anything other than the laptops). my laptop is a macbook pro 2.16 GHz intel core duo.
thanks in advance for your help. please let me know if there's any other information i need to provide.

I run my Pro tools from an external drive on my iMac and have no problems. Digidesign say this:
+To use Pro Tools LE 7.x currently, you will need to boot from a Mac OS X 10.4 (Tiger) startup system.+
+If you choose to upgrade to Mac OS X 10.5 (Leopard), you will need to install Leopard on a separate hard drive or drive partition.+
+If you purchase a new Mac with Mac OS X 10.5 preinstalled, you will need to install Mac OS X 10.4 (Tiger) on a separate hard drive or drive partition.+
+If you are purchasing a new Mac with Mac OS X 10.5 preinstalled, check with Apple to see if your computer is able to boot from Mac OS X 10.4.+
You may well have problems using your MBP disks however. I would suggest buying a copy of Tiger.

Why can't I see Tiger as a startup disk on external drive since upgrade?

Hi,
Before I upgrade my Powerbook G4 Aluminum 15" to Leopard, I decided to create a bootable external drive, both with Tiger and Leopard partitions installed on it, to try Leopard out and also so I can later boot into Tiger if I need to. Now that I've booted into Leopard on my external drive, when I go to "startup disk" in system preferences, the Tiger OS on the same external drive isn't showing. I know it's on there and it showed up as an option when I was running Tiger off of the PB's internal drive, but now it's gone when booted in Leopard from my external drive.
I do see the option to choose to boot from Tiger on my PB, but my fear is that once I upgrade it to Leopard, it won't recognize Tiger on my external drive and I'll be unable to boot back into Tiger if needed.
Does anyone know why this might be happening?
Thanks!

No but you still can boot up into Tiger if you want to. Plug in your external HDD. Restart your computer holding the option button. You'll have the option to choose which start up drive you want to boot into. That's how I do it all the time.

Why can´t I install system on ext. disk??

Why can´t I install my system on an external firewiredisk to have an alternative boot disk? My dealer said I can do. Now I tried to install Tiger from original DVD to an external firewire 400 disk from lacie, that was originally formatted to mac extended in two partitions. Before installation now, I formatted one partition to mac ext. journaled. Installer didn´t accept that. Why?

I'm not sure that's correct. "Not sure" because of the 10.2 issue, but I can say definitively that you can boot a both a G4 PB running 10.3 and an Intel MBP running 10.4 from the different partitions on the same external drive.
The two issues are partition scheme and the formatting of each partition. For my example, both partitions can have the same format, but that shouldn't matter for this since partitioning is "above" formatting in the drive architecture.
PPC machines must have an Apple Partition Map (APM) partition scheme on the boot drive to boot (they can't boot from a GUID drive). The Intel Mac OS installer requires a GUID-partitioned drive to install onto, but Intel Macs don't require GUID drives to boot. In other words, the Intel flavor of the Mac OS can't be installed directly onto an APM-partitioned drive with the install discs, but the OS can be cloned to the APM-partitioned drive. I have a LaCie external, APM-partitioned, and I use SuperDuper to backup my MBP and my wife's G4 PB running Panther. The external drive successfully boots my MBP and her PB.

Why can't I install iTunes on windows RT? Is Microsoft deciding what software I can use?

Why can't I install iTunes on Windows RT? Is Microsoft deciding what software I can use?

Welcome to Apple Support Communities
Theoretically, Microsoft is deciding what apps you can install. In Windows RT, you can only install apps from the Windows Store and they must be ARM-based, things that Apple and iTunes don't meet, so you can't use iTunes in Windows RT
