My Hitachi 5K160 arrived yesterday. Unfortunately, I missed the step about using a size 8 Torx screwdriver to remove the old drive from the bracket. I was still able to get the drive in the MacBook without the bracket, but I need to get the bracket off so I can put it in the 2.5" SATA enclosure that will be arriving today.
The drive seems to run fast...it was copying about 16MB/sec using SuperDuper! I selected 31 GB for my Windows partition with Boot Camp Assistant which made the partition 31.7 GB...just under the FAT32 limit. I don't know if I'll keep the partition as FAT32, but at least I have the option to and shouldn't need more than 32 GB for Windows.
Once I get everything up and running again, I'll be a very happy camper
