Is There a Sample Driver?

Yes, you may get it over here. The sample driver, which demonstrates presence of a bus filter by adding a new compatible ID, "BffDevice", to the compatible IDs list, must be installed on Windows 7 or higher, x86.

If you have an old CalDight T3/T4, you may also try the experimental driver, which will add "BffDevice" compatible ID to each of the disks inserted to T3/T4. Thereafter, you may run as administrator asm106x\create_raid_volume.ps1 in PowerShell to create a RAID 5 volume with those disks.

Caution: Make sure you have backed up data in your disks before you run asm106x\create_raid_volume.ps1.
