Bear in mind that IDE drives have not been made in at least 3 years, and so any drive you buy is at best going to be old stock(even if unused) and probably more likely going to be used. Both the physical age(the manufacture date usually printed on the label-sometimes explicitly, and sometimes in the form of a date code that you look up online as to how to decode) and more so the usage hours(easily readable by a program like SMART Utility) can lead to death of a drive. If you installed a 6-year old drive with 100,000 power on hours(as an example), it's probably not surprising that it failed shortly after installing.
High capacity laptop IDE drives-particularly "low mileage" ones-are getting hard to find and increasingly expensive.
For that reason, my Powerbooks that I actually use have solid state drives. I use mSATA drives, which can be had for $40-50 in 128gb. There are several adapters available on Ebay and elsewhere that will allow you to fit connect an mSATA drive to a 44-pin IDE. I've been buying some for about $10 from China that have the same form factor as a 2.5" laptop hard drive.
These have a lot of advantages-especially on later ATA100 Powerbooks. The adapters I use-at least in sequential read speeds-will nearly saturate the ATA bus(the adapter has an "overhead" of about 8mb/s). This will perk up your computer very nicely, while also helping your battery life, making your computer quieter and cutting down on heat. IMO, they're a win-win-win, especially since it's not that much more expensive than a "low mileage" 100gb 7200rpm drive.
