what is the exact use of the 2 floppy drives??
No use anymore,in the past we only had floppy drives.So to play a game or run a program everything was kept in memory,in order to make a hardcopy you needed to connect a floppy drive so you could save the data you created.
Think of text letters and datasheets,spreadsheets etc.
The first hard drives were small in size and after a short while it was possible to install a dos operating system so you could start the pc without using a floppydisk.
To go even further back,first media that was used for hardcopies was audio tapes.Took several minutes to load the 64kB in memory to run a game.Well,that was after the 4kB machines (zx-spectrum i believe?) also at that time came the 5.25inch floppy drives,you could fold those disks,as they seemed to be made completely out of paper(carton?)
Anyway,the 3.5inch floppydrive was a big step forwards,more loading speed etc.So it was handy to have 2 of these devices since a new operating system came on several disks and this way you had to swap less when reading the disks,same went for games that came on multiple disks.
So the pc hardware builders found it usefull to add this feature as standard.And it's still here today although not used(maybe a few ppl do?)
Today we use the same principle by using multiple hard drives or more sata drives).
To get to your problem,you have connected to sata port 5 you say?I believe port 5 to 8 are the silicon image raid connectors,1 to 4 are the nvidia ones,you want to use 1 of these.I read somewhere that for 2 sata drives you want to connect to sata 3 and 4.With 1 drive i don't know,have you disabled ide drives in bios?
Somehow i feel the pin message points to a hardware problem,plz try all sata ports one at a time,also try a different sata data cable,perhaps it's damaged.After setting the bios correct it should really work,if not your drive is bust,this can happen with new drives(as with any hardware)
I knew someone that thought he had a persistent virus on his hard drive,after searching and talking for more then a month he decided to take it back to the store and his new HD he then got worked like a charm.
