How did you configure the enclosure? RAID 0, JBOD, or spanning?
Looks like spanning is the correct setting for this setup.
Also, I've read elsewhere in this forum that DTV reserves about 100 GB of disk space in a partition to itself, for recording showcases, and such. That stays fixed, no matter how large the disk. This makes our calculations more interesting:
320 GB (220 recording space) = 50 hrs MPEG4 HD programming
750 GB (650 recording space) = 148 hrs.
1 TB (900 GB recording space) = 204 hrs.
1.5 TB (1.4 TB recording space) = 318 hrs.
2 TB (1.9 TB recording space) = 432 hrs.
Can anyone confirm if these recording capacities seem correct? Someone mentioned their Seagate FAP 750 was yielding close to 150 hrs. recording capacity, so these figures may be pretty close.
