62 file size

[Thrall]

I recently updated my HDVR2 to 6.2, now with Tytool each program is has 4 fsid's per 1 gig, on 401b it only had 2, my understanding was the tivo stored in 512meg chunks, did that change in 6.2 or are my programs being scattered around the drive? everything works fine extraction etc. Kinda curious if maybe I did something wrong using 62small and
mfsrestore -s127 -xzpi on a 200gig drive.

Thanks
