I have this old PII MMX 266 MHz laptop that I got for free. Right now the dead hard drive in it seems to be the only problem. It's only a 5 GB drive, and I assume 4200 RPM at the most. Am I going to have any issues if I get a 20 GB 5400 RPM HDD? Am I likely to experience problems with the new drive being much too hot? If it matters I am looking at the Seagate ST92011A. Thanks!
