Hp dv7 hard drive

[Don53]

Hello,
I have a HPdv7-4910 laptop with dual "MK5056SY" hard drives. I have been getting a message for imminent hard drive failure on the "C" drive. I saved an image of the drive and purchased a new replacement drive. The problem is I have the back cover off and do not know which drive is the "C" drive. Is there a way to know which of these ddrives I need to replace looking down at the unit?
Thanks,
Don

Remove one of the drives.
If the laptop gives boot error when you turn it on, the drive you just removed is the one you need to replace.
