Windows 7: Sata Port Numbering

Sata Port Numbering

Sata ports are numbered on a mobo but I have alwarys had trouble relating them to Disk numbering in Windows Disk Manager. I have never seen in the bios what port a disk was connected to.

Which brings me to my question. Has anyone ever seen this behaviour? When I set up a rig with multiple disks. I clean the OS disk and plug it in alone by it self. Then after I have verified it will boot I will add a disk and clean it for third party apps. (clean means partition and format). Then I may have one or two more disks with data to install that was in another rig. I never cleaned those I just plugged them in. I noticed that my bios was hesitating on the boot as it read the disks. So I took the data off and cleaned them. Then installed them one at time each time booting letting windows install the driver and write the "System Volume Information". This caused a much smoother boot in the bios.

This makes me wonder what is in the "System Volume Information" that confuses the bios? Probably Disk type, Disk size, etc. Maybe a reference to a particular port?

It's most likely related to the SATA port numbering on your motherboard, and your BIOS setting for which drive to boot from first.

Make sure your boot drive is going to be in SATA port 0 (first one) as your motherboard dictates (they're all different) Then make sure you have the boot order correctly set in BIOS, ( I turn off all other boot devices and just use the boot menu on my motherboard to switch around if needed )
