I did connect a fourth external sata hd at the jmicron controller (needs to operate as a standalone hd) (i plan to connect a 5th sata hd at the ezbackup connector, after removing the cap). This hd does not show up at the bios or in windows (when using partition magic). The external sata hd is formatted and contains data. When i choose in the bios the option "raid" at the jmicron controller (just testing), the hd shows when booting. Still nothing in windows.
I have installed jmicron raid controller software (because i thought i needed to install a jmicron sata driver, to make the hd visible at windows), but no result. Anyone has a clue? Thanks!
Hi,

You can actually run 4 sata hdd's off your intel ICH7 southbridge, and I would highly recommend this over trying to get the JMicron and/or the SiliconImage crap(ez-backup) working.

Plug your drives into SATA 1 (red), SATA 3(actually#2 black), SATA 4 (black), remove the jumpers off the ez-backup area, and plug into the right yellow ez-raid port (actually SATA2). I don't remember the physical marking of the right ez-raid port, so please forgive me.

If you have the jumpers off and boot with the drive attached, you'll see it in the list of the ICH7 area as your box posts, if it's in the wrong one, you won't see anything. Also, you may want to set the DH Features Change option in the bios to Enabled when you take out the jumper and attach the drive to have it tell the SiliconImage crap to turn off.

Bingo. You have 4 hdds on ICH7 and can turn off JMicron in bios.
