When you use AHDI to boot off of a hard disk you should have a floppy disk
in drive A.  The ST will not boot off of this disk unless it has a boot 
sector on it.  With a formated disk in drive A the ST will boot Very quickly
from the hard disk. I usually keep a copy of "SHIP.PRG" on drive A, which
I usually run before I turn off the HD.  Note be sure there are no open
windows to the Hard Disk when you run SHIP.PRG.  As for why the light stays
on, I can only guess it has to do with the fact the ST is trying to read
drive A when no disk is in drive A, and therefore is getting some sort of
read/drive error.

Unlike MS-DOS system The ST looks for a BOOT sector first at the Cartridge 
Port then on Drive A, Drive B then it looks for a Boot sector on DMA Logical
Unit 1 (The Hard Disk), If it finds a boot sector on drive A it boots drive A
and If It Does not Find a boot Sector on Drive A it looks else where until it
finds a Boot Sector.  When you Instal AHDI you are actually installing a Boot
Sector on the Hard disk.
