All Drives Dissapeared from BIOS

[EonDel]

Starting my system the other day and all of a sudden all of my HDDs dissapeared from the BIOS, the only drive visable is the DVD drive. Now the fact that they are all gone and not just one leads me to believe the drives are fine its just the HDD controller on my MOBO is toast. Just wanted to toss the question out there to anyone who had this issue before to see if there is any other reason before I buy a new MOBO

Thanks

Are the drives SATA ?
I have come across sata leads coming loose from the motherboard, replugging seems to work for awhile until the next time.

pretty sure I checked but I'll give it another go, thanks.
