iSCSI - Windows 8

[tzpmrz]

I'm mainly just doing this as a learning exercise. I'm trying to connect a windows 8 machine to an iSCSI volume.

NAS4Free 9.1.0.1 (636)
so far I'm not really having any issues with the free NAS itself (other than a major learning curve )
I've been able to create a raid-5 volume using 4 disks and formatted it to UFS ( even though I'm want to use it with a windows machine )
started the iSCSI and I've actually got the Win8 machine to connect using CHAP.

the disk shows up in the windows disk manager as a healthy primary partition that I can't do anything with.
I guess I always thought it would look like a hard drive that I could format in windows, that windows would do all of the overhead of a file system and the NAS would just server up blocks of disk. ( any web links or suggestions greatly appreciated )

I'm having a hard time finding any more information about how I should have configured this for use with windows (7 or 8).
Should I have not formatted the disk at all?
Should I have formatted it as NTFS or UFS?

sigh... I rebooted the win8 machine and now it works fine.
figures it would start working the second I posted for help.

formatted the drive and copied some files to it. seems to have great performance with the few files that I've copied over.
