5 - 30 minutes
Well, I'm now on my third hard drive in this little laptop. No more clicks of death though as I've moved onto an SSD.
Easy once I had the bracket. The other bracket is off somewhere lost amongst other broken hard drives.
Read IFixit repair guides before getting ready to do the drive. I went to do the repair prior to having the bracket. Otherwise this repair is one of the easiest I've ever had to do.
