Connecting a PS3 HDD to a PC

My PS3 stopped working and I never backed up the data on its HDD. Since I can’t power the console on, I can’t use the console’s backup utility. I was advised that it may be possible to connect the PS3’s HDD to my PC using a serial ATA cable and access the data on it. If this is true, can anyone offer specific instructions as to how to connect my HDD to my PC so I can access its files?
