Instead of buying a new sata drive, I was thinking about using an PATA to SATA adapter like the one seen here. Has anyone ever used a device like this and care to make a comment? Does it work well? any problem or special setups with the mobo/bios? Will the interphase require me to reformat the drive or can I just plug and play? and lastly, why do these products vary on price.....the range is from $14 to $35; what's the difference?
