What brand is the 250 one?

Do you have experience using them in MacBooks? I'm asking because I'm worried about heat. When I got a larger drive for my iBook, it ran hot and the machine was never really the same after that (would overheat and shut down).

I just bought a WD 250GB SATA for my MacBook today.

Installation took less than 5 minutes. Only required two tools:

1) Tiny philips screwdriver. One was included with the casing I bought for my drive, so that was easy.

2) Hex driver. I didn't have one of those but a small flat/blade screwdriver did the job just fine.

After that I formatted the drive with Disk Utility, installed GUID partition with Disk Utility, then used free download program Carbon Copy Cloner to copy the existing 60GB drive across. That took about 2 hours.

So far working well. And it's nice to see "179.84 GB available" on my screen!
