Mac Book Pro just replaced hard drive, new drive isn't showing up

Hello I have a mac book pro that had a Hitachi 320GB drive and it failed so I purchased a Seagate 500GB SATA drive and it's not showing up in the disk utility .... Any suggestions

Could you please be a bit more specific. What are you booted from? Presumably not the new drive as it is not formatted, and not the old drive as it has failed.

Are you sure the cable on the new drive is firmly pushed in?

It's a new drive the old drive keep giving me the folder flashing with question mark I took the drive out and put it in another system and couldn't recovery most of the data so I got a new seagate 500GB installed the new drive booted to mac os x install dvd then went into the disk utility and the newly installed drive is not showing up ... Should I take it out and partition it with another computer or??

You could try that, but it sounds like there might be a problem with the drive cable in the computer. Try reseating the cable first.

I just opened it back up and ensured the cable is firmly attached to the drive

It is also possible that you only plugged in one cable. Disks usually need to have 2 cables, one for the data and the other for the power (unless in your PC a single cable holds both, which is unlikely). So make sure all cables are plugged in, and also make sure the other end of the cable is plugged into the PC's mainboard.

Only one cable in MacBooks, Rindi.

If you choose the correct model of your MacBookPro at the iFixit site, it will give you the part number for the ribbon cable and a link to purchase one:
