New tests with a 1.5TB EHD
After my unsucessful attempts to use a 2TB, I tried with 1.5TB. As some folks here had good results with a 1.5TB, I hoped I would work for me too.
I bought a iPro Drive 1.5TB (IP-HDE1-1.5TB) and hooked it to my 9242 receiver. I was pleased to get 200hrs in HD or 1505hrs in SD. I then checked the partition on my computer: The 1397GB on the drive where partitioned like this: 1GB, 500GB, 500GB and 396GB.
It looks like the receiver can handle all the available space on 1.5TB but not on a 2TB on which it uses only 1TB.
Besides, the 1,5TB iProDrive is very quite (I can barely hear it compared to my other Comstar 1TB that was pretty noisy) and it gets barely warm. On the long run, I'll see if it's all that good.
