Replacement hard drive slows everything down

[SavMBP15]

MBP mid-2009 15", 2.53ghz, 8GB Ram

I replaced the factory hard drive today with a Western Digital Scorpio Black 500GB 7200 RPM drive. Before I installed it I used Carbon Copy Cloner to clone the drive and then I put the new one in.

As expected it took a few moments to find the drive (searching for startup drive), and then it booted. From that point on, everything was lagging and whenever I clicked on anything I would get the spinning beachball. I tried resetting the pram and power settings, and repaired all the permissions. I changed the startup disk to the new disk under sys prefs.

With all that, the extreme lag persisted. I put the old drive back in and everything worked fine.

Any ideas?

My only guess would be that something is wrong with the hdd

Yeah I agree with this, considering the black is WD's performance HDD. Did you run a disk speed test?

No, sure didn't. Best way to run this test?

It was, but looked like it had finished. Plus it was happening at the login screen.

Is this a restore from CCC? Have you tried a clean install instead?

hmmm, i read once it might have issues if you didnt select the drive in startup disk preferences it could cause odd issues, but at the log in screen i would imagine it would be passed that problem. might check it just for giggles

I'll try a clean install next. Probably won't get to it until Tue or Wed. Thanks.

If you have the App Store look up Black Magic Disk Speed Test. It's free and will tell you if its up to spec in terms of speed.
