Why would the Firewire Port and/or External DVD-RW suddenly not work?

Question

Hi, it's me again. I swear, I must be destined to just use Windows machines...
Anyways, I have a used/refurbished iBook G3 500MHz 320MB RAM Dual USB (1 Firewire)laptop running OS 10.2.8 that I bought a few months ago. I went and purchased an external Firewire/USB 2.0 DVD-RW drive as I only had a CD-ROM drive on my machine and I wanted the option to burn CD's or watch/read data from DVD's (I know that with my slow processor writing DVD's -other than data- would be a stretch and have other machines to do that with anyways so it wasn't a concern really). I received it and installed it, also installed the free version of Toast that came with it, and the drive worked fine. I have not needed to use the drive since then and have not used the laptop much at all since then really, but I do need to say that I did end up adding a new user account, though I can't remember if I changed the original Admin account and then still have the one I created myself when I first started the laptop after I bought it (had a fresh install of Jaguar on it, but I have no disk to re-install with if needed) or if I created a separate (new) account and ended up deleting the Original Admin accout (I know in Windows, you cannot delete the original Admin account but I do not know if that is the same for OSX or not). I did this as I wanted a master Admin account that I just wouldn't really use and then wanted the other as my main account (and use it to connect to my home windows network) and for some reason it would not let me put a check in the box to allow that account to do so (from either Apple or my user accounts) and so I know that my main user account now is set up to allow it (was it the old Apple user account or a new one, I can't remember- sorry).
Ok, so that is the back story to my problem, which happens to be this:
I just bought a new chip of RAM (512MB to make it a machine with 576MB RAM total) and as I had been looking at getting OSX Tiger (but didn't want to do it without the extra ram and had been considering Panther instead as well), I thought it was necessary if I wanted to not bog down my machine. I bought the Install Disks on DVD for Panther, as well as an upgrade disk (DVD again) for Tiger, therefore letting me use the External Firewire DVD-RW to install Panther, and if I liked I could go ahead and upgrade to Tiger (and if I didn't like it too much, or it slowed things down too much etc, then I could always go back to panther and have both available for future options). The extra RAM coming in handy here definitely.
So I was going to install the RAM today, and decided to go ahead and test out the External DVD to make sure it could boot from it (before making any changes to my system) and then go and install the RAM, and after that, install Panther to start... But I plugged all the cords and cables in, used my laptop with AC power even, and I could not get the External to show up at all... (kinda like the very current post right below mine but for the G4- it worked before, but now the firewire External just does not show up).
I only have USB 1.1 on this laptop obviously, and I don't even know if you could do a boot from an external with USB 2.0 if my laptop had it (the DVD player does). I was recommended to boot with an external firewire DVD or firewire to another machine with DVD capabilities to do the install. So my problem right now is getting slightly bigger, as of course, I can't seem to momentarily find the stuff that came with the External (spare USB cable to check and see if the laptop will recognize it at least with that and to show it is the firewire that is not working properly, or the disk that I used to install it -might have been only used to install Toast free version if it didn't need any drivers, but I don't know where that or the instructions for installation sheet currently is -- I am looking for it, but I have switched bedrooms just last week and I also seem to be missing a few other Windows laptop disks as well so there is a good chance that they are all together, I just need to figure out where, heh.)
I am waiting currently before installing the memory, though if I don't get the External working tonight, I may go ahead and do it first as at least I will have more memory on my laptop then, until I can get other stuff functioning and be able to do the Panther install.
But my main question is, is there something that would cause an installed external to suddenly not show up in OSX? Since I hadn't used it since that one day, and it was unplugged from the laptop itself, would that end up doing it, or more likely, the changing of the user accounts (though I have been trying to test it with different types of media and through both of my user account (which are both "admin" ones), though I do still have one of those being an account that was on there when the External DVD was first installed, so it really shouldn't have done this at all (one would think). So how big of a chance is it that the firewire has somehow gone dead and this is the main culprit to my wasting the past 4 hours on this???
I am currently scavenging around for an extra USB cable to try and test the External that way and will post the results when I can... I love the look and idea of macs, now I have a mac and want to upgrade it even, but why is it that whenever I attempt to use it after having not used it for a bit (and try to make the iBook feel better by using it more as I am sure it feels sad and alone sitting on the shelf while my Windows Laptop gets more attention), or try to fix it when it can be made better (and therefore used more often), the mac (all macs really), just seem to get all pissy and cause problems and make me spend hours upon hours trying to get things to work again??? You have to admit it, I am "mac cursed"... sigh I can program in 4 or 5 computer languages and am very advanced at many tech things (the ones I am not as good at I am still usually Average or Medium skilled) so it makes me wonder why I have so many tech problems with Macs when they are supposed to be the "easy" OS to use...

Actually, I think I have it all working now. After going back to the Plextor Website, I found out that the switch between the USB and 1394 ports only gets activated (switched over to the other) with you turn the device off first, move the switch and then turn it back on. I was sure that I had done this with the ibook, but maybe not as when I went back and did it with first the USB and then the Firewire cables, it did work. I definitely knew that I had not done this with the Windows laptop, the reason it would not have the USB work for me on it.
but back to the iBook, I was confused as it was only showing up as a DVD-ROM (which I guess is what they do until you actually open up the burning software to then be able to burn to it), and it also had the wrong Model #, which after more research, showed that it was the Internal DVD drive model version (PX-708A) compared to the actual model version (PX-708UF) which is the USB/Firewire (External) model. The firmware was really out of date as well (from June 2004 I think, v1.06) and they had v1.12 from Spet/Oct 2006 available so I went to get that (which was a hassle). They had nice easy Windows self extractor/installer packs, and then the BIN files for use for all systems (Sun OS/ Mac OSX/ Mac OS/ Linux etc as well as usable for Windows), and those needed a special Firmware Updater Application which was OS specific. Only I had the hardest time trying to get the OSX one as it would send me to a FTP site and not give me any clues as to which file(s) I needed to get and the Mac OS version was just for older 9.2 or below versions and didn't want to install under the OS Classic mode.
I ended up using my windows computer which made it easier to view with the FTP stuff as I have FireFTP in Firefox, and downloaded the files I thought I needed (to test out), and then realized my silliness, and just downloaded (as well) the Windows Auto Extractor/Installer as the Firmware is the same for all OS's, just the way to install/update it was different... So I hooked the DVD drive to my PC and updated the firmware, checked it out on here before moving it back to the ibook, where I checked that it still worked and had the new update version showing, which it did, and now I have my fully working and newly updated drive ready for the OSX installations... I had attempted to update my Jaguar system as well while online, but it had no new updates available (I guess those were all mostly Tiger updates that were just recently released).
I am now off to install my additional RAM, and after checking that it all shows up correctly, I will go ahead and do the Panther Install (and test it out and see if I like it or not).
For anyone that currently uses Panther on any mac, are there still any major problems I should know about before hand, or know about things that they have mostly fixed (like the issues with Firewire ports and External Drives that they had around the time Panther was first released for example)???
Thanks to all that helped... I now know to attempt an "eject" of any external HD (which I do have one that I will setup to use after I get Panther on the ibook) or CD/DVD drive instead of just unplugging the USB/Firewire cable.
