I have a new gigabyte ga-Z77x-UD3H mobo (http://www.gigabyte.us/products/product-page.aspx?pid=4441#sp)that is supposed to have: 2 x SATA 6Gb/s connectors (SATA3 0/SATA3 1) supporting up to 2 SATA 6Gb/s devices 4 x SATA 3Gb/s connectors (SATA2 2~5) supporting up to 4 SATA 3Gb/s devices Marvell 88SE9172 chip: 0.2 x eSATA 6Gb/s connectors on the back panel supporting up to 2 SATA 6Gb/s devices.
The problem is the Marvell ports do not seem to be hot plug capable even when enabled in the BIOS. I have to re-start the system for Windows to see the esata connected drives.
I have read that perhaps Windows was not installed properly and the Marvell drivers are not working, but the device manager says the device is working.
My system is Win7 x64 Marvell controllers (Marvell 91xx Sata 6G controller) is listed in device manager as a Storage Controller and not under IDE ATA/ATAPI controllers (that's where the Intel controller is).
