Now here's what I did:
I received the Conceptronic CH3SNAS (DNS-232)
The other supplier couldn't supply the 2x Samsung 750GB drives yet, so I bought a slightly more expensive Samsung 750 GB at a local supplier.
(I just couldn't wait)

Formatted as a standard drive. Alle worked well and was pumping it full with data.

Today I received the two identical 750 GB Samsungs from the supplier.
I removed the 750 GB from the NAS and put it in my PC.
I couldn't read the data. (Reading through this forum, now I believe I had to install a Linux FS driver and it would be possible)
Meanwile I formatted the two new drives as 500GB Raid1 and 500GB JBOD. Fine!!

Well I needed to acces the data on the first (and full) 750GB disk, so I removed it from my PC, pulled the two empty 750 from the NAS and inserted the full 750 in the original left slot.

After power on, the drive was accessible, the data was all there.

I can read and write, but even when there's nothing being read or written to the NAS, the single disk is working vigorously.

What's going on?

Is the drive being checked after re-insertion?
Currently I'm formatting one of the two new disks in my pc. I want to transfer the data over the network to the PC and the reformat the NAS with two drives again as raid1 500GB + JBOD 500GB.

Can anyone explain the disk activity on the NAS?

It's a long story, but I wanted it to be complete

I've read changing the powermanagement to 5 minutes and rebooting was an option.
After doing this, the drive in the NAS is working even harder.
I'm afraid, if I keep it powered on tonight, the drive is toast in the morning.
It's realy moving the head fast over the drive.
Sounds like a drive being defragfmented

Does someone have an explanation for this strange behaviour?

Well, no one provided an answer. So today I reformatted the drive and also included another 750. The drive that wasn't able to shut up before was placed from the left to the right bay to have the most "new" configuration.

I've reformatted the drives as standard, because I also wan't to implement the nightly backup that's getting so many positive results on this forum.

After reformatting the drives are both quit and the leds are ON and not flickering anymore in standby mode.

Still don't have a clue what the reason of the drive activity was.
Even with the lan cable removed the drive was searching for something on the disk....
The contents of the drive was accessible throughout the whole process (until I reformatted...duh!)

Printing out the backup procedure now, my next big project.....

This box was not designed todo the what you did. It keeps information in the config about the setup. If you move disks around with out formating them you might get strange behaviour.... as you noticed.

Pulling out the disk after normal shutdown and installing it in a xp machine and then putting it back in de NAS, makes the drive being different?
I assume that reseating a disk in the NAS has to be possible. The only thing remains then, is tat XP has written something on the partition/disk that makes the NAS confused?!

There is NVRAM on the DNS-323 where system configuration parameters are stored.
The D-Link web GUI writes these parameters to NVRAM to remember your setup after a reboot.
Perhaps when you switched drives (and RAID levels) the configuration parameters in
NVRAM didn't match the new disks anymore.

If you had Fonz's fun_plug installed and had telnet access, you could have inspected
the process list to see what process was accessing your drives, which might have
led to some understanding of the drive activity.
