SATA1 drive has priority over SATA2?

I have a MSI FM2-A55M-E33 Mobo

If I have drives plugged into SATA 1 & 2 connections, the SATA 2 Connection wont work.
It seems as though the SATA1 drive has priority over SATA2?

If 2 or 3 SATA drives are plugged in I can see them in the bios
In Win8 I can only see the drive(HDD or DVD) plugged into the SATA1 (I see it in the explorer).
It doesn't matter what I plug in, eg HDD or CD Rom, it will only let me use SATA 1 or 2 but not both.

Any ideas?

Not enough detail here to really help.

=>  Are all of the SATA ports enabled in the BIOS?

=>  What is the SATA access mode set to in the BIOS?

=>  Have you initialized all of the drives?  

=>   What does Disk Management show in Windows?

=>  Have you tried different SATA cables?

=>  And are you hot-plugging these devices, or are you making all the changes with power off??    (Notwithstanding the ability to hot-plug with AHCI, you should make all changes with power off until everything's set up correctly)

Not shown in Disk Mgment


Post a screenshot of Disk Management.   It's got to show SOMETHING ... at least the drive you're seeing in Windows.

Also, does Windows show any devices plugged in to SATA 3 and 4 ??

And what is the make/model/rating of your power supply?

Disk Mgment is an abbreviation of Disk Management

It's not shown, unless I swap SATA connections or pull out the other connection

SATA3 is ok, haven't plugged anything into SATA4, the Video card is covering it.

Disk Management shows SOMETHING ... even if it's a blank screen.

Post a screenshot of what it shows -- capture it with Alt-PrtScrn and save the resulting .JPG in Paint ... then just post that here.

Shall we presume the HDD plugged into SATA1 is the boot drive?

How large is the HDD you're plugging into SATA2 ?
Over 2TB ?

Nobus, you've done it again. Genius!

So weird, but having the boot disk in SATA1, Other HDD that wasnt showing in SATA2 & the DVD Drive in SATA3 all works. But if I change that config it doesn't work.

i have an ide disk drive here that works ok if connected as slave - but not as Master.
never found why; though it is seen in the bios.
it looks like a bios problem - or a motherboard problem to me

anyway - thanks for posting that info - always useful
