Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Did you get any further on your problem after updating the disk firmware?
I experience exactly the same problem when i try to make a RAID1 with two Samsung HD204UI drives.
I'm using Fedora 14 (after first using Centos 5,6), i've updated the firmware although i've purchased the drives last week and i read somewhere that samsung is using the new firmware in the disk produced after dec. 2010.
I've got a mini itx board (Jetway jnc96fl) which has 4 sata ports, 2 with the intel chipset en two on the jmb363.
When i make a mirror with the intel ports there's no problem. Only with teh ports on the jmb363. Because i've bought this board to build a nas server with 4 2TB drives in Raid5 i hope there will be a solution. otherwise the board is useless :-(
Also good to mention is, that before i got the smasung drives i did some testing with 4 500GB WD drives, and was working ok.
So it seems to be a problem with the combination of the HD204UI's and the jmb363.
Well i hope you have found something in the mean time.
I'm sorry to disappoint you. Unfortunately I haven't found any solution yet and, upgrading the HDs firmware, did not change anything.
I have temporarily bypassed the problem not using the jmb363 controller but an "IDE to SATA" converter which is not giving me any problem at all. Obviously it's a very poor solution but it does the job for now.
My hope is that, with the next Ubuntu/kernel upgrade, the jmb363 will be better supported... (fingers crossed)
Yeah well... you can disable the jMicron controller if you have enough SATA ports to do what you wanna do.
In Breekie's case and mine we want to have a RAID5 and, if we disable the jMicron controller, we would end up with 2 SATA ports only... which are definitely not enough. That's why a workaround is needed... :-/
In fact what I'm looking for is a PCI-E x1 with 2 or better 4 SATA ports...
The 2 port one is quite cheap. Even less than £10 in England. The 4 port one starts from £40/50...
I will try one of them... sooner or later.
Thanks for the links but i already searched (and found these threads)
The controller is on a mini itx (jetway jnc96fl) i wanted to create a nas with 4 sata disks in raid5.
There's only one pci slot on this board. External sata controllers with 4ports are mostly pci-e, so this is no option either.
I think my project with this board will end here :-(
I'm still on Ubuntu 10.04 but soonish I should upgrade to Ubuntu 12.04.
Once upgraded I might give it another try, unless that computer dies first (sometimes it feel like it can't take it anymore... LOL).
