Hey there, Got this mobo atm, running on raid 0, using 2 Samsung 256gb pro ssd. Had some minor issues with the bios files, since i have been told that the 2 last bios are buggy, so i decided to install the 16xx version. I have finally finished to installed w7 atm, but this damn issues keeps coming.. Everytime i want to move any file from any of my current drives connected from the Marvell sata ports, starts copying and then STOPS and never finishes at all. This is the 3rd time i have installed w7 64bits on this mobo, using the latest drivers and also the drivers that came with the mobo, and yet the problems continues. I dont know what else to do, im getting frustrated because i like this mobo but im thinking of return it and get another one or perhaps another brand. Has anyone heard from this issue??? It seems that im not the only one, because it does show on the asus website that it takes forever to copy files. "The SATA ports on my motherboard behave quite strange lately. SATA devices connected to it may show one or more of the following symptoms from time to time: - SATA devices not detected at POST stage or inside CMOS setup screen. - SATA HDD cannot complete the installation of operating system after enabling AHCI or RAID function. - Computer takes forever to install operating system or copying files. - Operating system may hang while large disk access operations are under progress. " Thanks for any help! Btw, everytime i start a w7 clean installation, i try to copy files from different drives, no problems, the issues may arrise when i start installing the drivers. I know it's my drivers causing the issue, they were working before and the sata cables are brand new as well.
