Advertisements For those that are interested in maxing their Premiere, RussMuscle and I developed a procedure with a new tool that can be used to expand your premiere to 8TB. No intermediate drive is necessary. First pick up the latest MFSTools from the post here. Then follow the following procedure. sdX is your source drive and sdY is your 8TB drive. You can use fdisk -l or lsblk -o name,size command to look at the sizes of the attached drives to determine which is the source and which is the 8TB. 1) mfscopy -aiM 4000 /dev/sdX /dev/sdY or mfscopy -aim 2000 /dev/sdX /dev/sdY This step does 2 things for us. First it copies and expands the source image to the 8TB drive limiting the expansion to about 4TB in size. Second it rearranges the original partition layout from 1,13,2,3,4,5,6,7,8,9,14,10,12,11 to 1,11,2,3,4,5,6,7,8,9,14,10,12,13. The reason for this will be apparent later. Boot the drive in the TiVo to make sure the image connects to the TiVo servers and updates correctly. 2) mfsadd -xM 6000 /dev/sdY This adds a new partition pair 15 (application) and 16 (media) to the image which adds another 2TB of recording space. Now the Premiere only allows for 15 partitions on the internal drive. So if you put the drive as is into the TiVo it will divorce off partition 16 leaving you with only the application partition that describes the extra 2TB recording space which now does not exist. When the TiVo tries to access this space, it will error out. This is why we need to to the next step. 3) apmfix /dev/sdY The main purpose of this step is to coalesce partition 15 and 16 into partition 15. It also does some other manipulation of the APM and house keeping chores. 4) Boot the 8TB drive in the TiVo and allow it to divorce the now non existent partition 16 if it asks. Once it boots up fully, you will need to connect it back to the computer for the next step. 5) 8TBprep /dev/sdY The main purpose of this step is to make room for another expansion. Since mfscopy rearranged the partition layout when it copied, it placed partition 12 and 13 in such a way we can coalesce 12 and 13 in 12. Then we can rename partition 15 to partition 13 and now we are back to having 14 partitions. This allows us to add another partition 15. 6) Boot the 8TB drive in the TiVo and allow it to divorce the now non existent partition 15 if it asks. Once it boots up fully, you will need to connect it back to the computer for the next two steps. 7) mfsadd -x /dev/sdY 8) apmfix /dev/sdY 9) Boot the 8TB drive in the TiVo and allow it to divorce the now non existent partition 16 if it asks. Once it boots up fully, you now will enjoy 8TB of recording space.
