Make sure termination is correct. Check this page for more information.

Ok, so the harddrive definately has no termination, not even any old resistor-packs?

Btw, the first harddrive usually is jumpered as id 0 - ie all id-jumpers removed. This shouldnt matter as it works when only the harddrive is attached, but for wierd problems, wierd things can be worth trying .

The ImpactII has onboard termination and should have id 7 per default. It was the harddrive and id 0 I was talking about.

Sounds very reasonable.

Unfortunately, there is no option to lengthen the wait of the ImpactII controller at poweron. Is there any jumper on the harddrive to enable/disable auto-spinup at poweron which you could try changing?

Aye, I know, but maybe the ImpactII acts different when it has to tell the drive to spin up.

There is one more option, a long shot actually which most likely wont work. If you have access to an EPROM-burner, you could update the onboard ROM-driver (gvpscsi.device) to the latest version and hope that version waits longer. Check this page.

Amiga version numbers are composed of two integers which are written out in the form number1.number2, so 4.15 comes after 4.5, just like chapters in a book.

But seriously, there is no need to argue about this as Ralph Babel who wrote the driver writes on his page that 4.15 is more recent than 4.5.
