Looks like a bug in the IDE driver of the kernel to me. It assumes that interrupts are enabled for the controller which is not the case for VirtualBox (iirc the BIOS disables interrupts). Visopsys polls a variable which is set if an interrupt is asserted to wait for completion of IDENTIFY. The waiting times out after a while and an error is returned. The detect routine will skip the drive. CD-ROMs are working because the code issuing the IDENTIFY PACKET command doesn't wait for an interrupt but just waits until the busy bit in the status register is cleared.
Will close this ticket as invalid for now. If someone finds out that my findings are wrong please reopen and correct me :)
Confirmed. Not sure if the visopsys kernel is too fussy or if the IDE emulation of VBox isn't 100% perfect.
