Hey guys, I wonder if anyone can help?First things first here is my system as best as i can describe it.....
This Pc Was Built By Dell in 2005 but i added a few tweaks here goes:
Dell Dimension 5000
Intel Pentium 4,3.0 Ghz Processor
Graphics Card: ASUS EAH 3650 HDMI 256mb, to HDMI Pro 2 Range Cable, to 32" WSTFTHDTV.
(The cards cheap..i know but the Glaciator cooling fan is the same size as the tail rotors on an Apache Gunship....)
Hard Drive: Internal :80GB Maxtor 6y080mo,250GB WDC Caviar.
External: Lacie 250GB,Freeagent 320GB,Freeagent 500GB,Freeagent 1TB.(2.4TB Total)
Memory: 4X1GB Orca DDR2 Modules (Only 3GB detectable on my 32b Windows XP, Got 64 Bit Version But Don't Really Fancy backing Everything up.)
D-Link Air Plus DWL-G520 Wireless PCI Adapter(rev.B)
Odds & Sods: USB Audio with full 7.1 Surround Sound.

Now I have windows installed on both sata hard drives and i have the western digital caviar set as primary,
i can access most things on the maxtor through my computer (just not the desktop folders and shortcuts),
which is fine as i can turn off my 250gb drive via bios and my 80gb will boot up, allowing me to access it all.
Now i just bought a 250gb hitachi Deskstar brand new which is a sata as well,
now I don't know what i'm doing wrong
but no matter what combination i put the drive in (whether swapping it for my 80gb or my 250 gb)
i cannot seem to get my pc to detect it,
i have even put in my windows sp3 recovery disk and tried to boot off rom drive
but it gets so far then says it cannot continue cos no drive is detected,
i have also had no bootable disk found or detected,
my pc is in a large desk and because of all the wires hubs and what nots i have attatched to it,
it is very painstaking to access the inside of my pc and by moving it in and out, connecting and unconnecting wires i am going out of my tiny mind,
the new drive needs to be formatted and partitioned and an operating system needs to be installed on it,
I bought a docking station so i can have it as external
but my pc doesn't detect it in docking station without O.S,
please can someone, anyone help by giving me a clear guide or description i can print out and follow so i do the least amount of work, simple trial and error is mind buckling for my limited abilities
I am honestly at my wits end and would love to have this running before my birthday in December,
any help much appreciated.
