One very quick (and missing several key things to be called complete) crash course in original xbox modding coming up.
First that looks like bytes to me (European version of number splitting)- it is not completely accurate (the whole 1000 vs 1024 thing) but consider the first three numbers (on in the case of E the first 4) and call them megabytes.
Still the only drive you can really use is E (you might be able to rejig a few things and increase the space/give you a 2 gig F drive*- MS shifted to 10 gig drives later in the xbox lifetime but left the partitions as they were originally).
The C drive is probably a fake one (known as shadow C in the hacks/guides/documentation) used to make sure people do not overwrite the true C drive (it is one of the two main protections along with virtual EEPROM but that is a different matter for a few sentences time).
X, Y and Z are cache drives games store things on to help with loading times, many programs will not even show them as they are liable to be overwritten at any time.
*a really old guide
http://www.xbox-scene.com/articles/formatf.php but there are easier ways using Auto Installer Deluxe- if you are new to this then Auto Installer Deluxe aka AID is the one stop shop for all things 360. It stopped being updated a while back but all that means is you might have to grab a new version of XBMC or some emulators.

Things on the 360 were usually built with the offcial xbox SDK so downloads are a tricky thing. For that we have the xbins network, many ways to do it but easiest is

If, when referring to the original xbox or xbox 360, anyone ever says you can find it in the usual places or has a N/A next to a download it is a safe bet they are pointing you towards xbins.
First things first just about everything on the original xbox (and 360 too for that matter) revolves around FTP. USB support is there* but it is tricky and only works with some smaller drives (2 gigs or smaller) so do not count on it like you might for the wii or the 360.
*several guides around but most people just solder a USB extension lead to the wires inside an xbox controller (like coloured wires to like coloured wires and leave the yellow connected).
It would be bad form not to mention that XBMC has some of the best streaming abilities of any device that is not a straight up PC- just about every big streaming protocol is supported but it can not be used for games.
Games from the hard drive- you are limited to either running from disc or extracting isos and running them from the hard drive. AID above has a toolset called xbox-hq PC essentials which has several programs to extract xbox isos and even FTP them for you. C-Xbox tool is my chosen program although you can pick what you like.
As for DVDs you can burn isos straight (usually wasting several gigs of DVD- nicely enough that does mean many can run from a stock xbox drive) or you can try making a multi game disc.
At some point though are going to consider a larger hard drive and this is where it can get tricky. There are four main modding methods for the original xbox- two hardmods and two softmods.
A hardmodded xbox is either a chip or TSOP flash and as it replaces the BIOS it can do what it likes and use whatever hard drive it likes.
The softmods (game hacks and hotswaps of hard drives) work just as well but for modding a hard drive as there is a little used feature of the IDE/pata spec that allows you to lock a hard drive to a device and the xbox uses said feature before the softmod kicks in and as such such you need a drive that locks. Several manufacturers and worse drive lines/models do not include this ability which means you can not use them, fortunately we have
http://xboxdrives.x-pec.com/?p=list
It is a bit trickier to find IDE drives these days but it is not that bad.
Just about all original xbox hard drive modding revolves around a custom version of linux called xboxhdm 1.9 (which you can find on xbins among other places). You do need a IDE/pata port on your motherboard though- the 1% of things the USB adapters do not support just happens to include these.
As for the virtual EEPROM thing liveinfo is the tool you want (match serials to the bottom of your xbox) and if you are dumping your EEPROM for use with these tools you want to make sure you are using the proper EEPROM and not the virtual one. AID and the sister tool SID have the ability to dump the EEPROM and hopefully work around any issues with virtual EEPROM.
Lastly the original xbox makes a stunning media player (indeed it is only missing the ability to play back higher resolution videos, especially H264 and record video from sources- you want something that plays back scene grade xvid then the xbox with XBMC is the thing to do it) and you will see it does have HD outputs but in PAL countries like yours it will be locked out, enigma video switcher can sort that and you can either make HD cables or buy them in
