    Does anyone have the pdisk output for a stock TiVo Premiere 320GB drive? I'm thinking of buying one to replace my HD, but am wondering if it is 4K aligned.

    Thanks!

    You're thinking of buying a Premiere to replace a TCD652160, or you're thinking of buying a 320GB hard drive that came out of a Premiere and using it in a 652, or using it to replace a hard drive in a computer?

    I'm thinking of buying a 320GB Premiere to replace a TCD652160. My intent is to upgrade the drive, but I want to make sure that the existing partitions are 4K aligned. The HD is not, and I ran into serious performance issues when attempting to use a 4K drive.
