Replacing hard drive in 6000HD

[kb2syd]

Years ago I replaced the 15 meg hard drive in my 6000HD with a 40 meg seagate. It works great. However, if I don't manually park the hard drive the system won't boot the next time. This is consistant.

Does the default 15 meg hard drive auto park and I just have a weird drive that doesn't auto park?

Thanks for any thoughts.
