From the Readme.txt in the WinUAE archive:
Amiga formatted harddisk support
--------------------------------
Requires Windows 2000 or newer with administrator privileges.
All Amiga formatted or empty drives (=zeroed partition table) are autodetected.
WinUAE does not care about interface type, drive can IDE or SCSI or even
memory card if Windows detects the drive in device manager.
Use uaehf.device to access the drive in HDToolBox.
Note that some versions of HDToolBox don't see drives with unit number > 6.
Remove some mounted harddrives (directory or hardware) to fix the problem.
WARNING: you can force all drives to be detected if you run WinUAE with
-disableharddrivesafetycheck command line parameter but be very careful.
Don't try to select and partition/format your Windows drive(s)!
NOTE: uaescsi.device or ASPI don't have anything to do with harddisk support.
So it should work
