 A 20 GB disc? It would be very old. Are you sure it supports AHCI respectively NCQ? 
 Try to turn off AHCI in BIOS before booting pfSense. Maybe also a BIOS update could help.

 funny i have turned of AHCI and that made it worse… then it didnt even get past the Boot loader.

 Try setting a different disk access mode in the BIOS like LBA or CHS. What hardware are you running on? Steve

 Try interrupting the boot loader to get to the OK prompt and do: set hint.ahci.0.msi="0" bootAs refrerrenced here:
