Answer to "Problem with 750 GB HDD"Have the same problem with WD 7500BPVT. after complete format I started with the Installation Disk. the Installation was fine, it took about 1 hour, but the system was very slow. I started the upgrade from leopard to snow leopard and the installation takes more than 10 hours, so I quit it. Is this normal?? I replace the old drive and I have no problems!!
