Since I saw some posts that the Edge (running TE4) can format drives larger that 3 TB properly, I thought I would test the Bolt on TE4. I did and so I thought I would post my findings on my Bolt when tested with a large drive. The drive I used for this was a 10 TB drive.
- Bolts can now self format drives larger than 3 TB properly. So far I find no issues with its use, however, I have not filled one up yet to near capacity.
- Kickstart 57 and 58 will put it in a GSOD boot loop (technically it is not a green screen but the verbiage on the screen is the same.) You can recover from this by using MFSTools mfsck to change the MFS header magic to 'OK'
- My unit has not gone through an OS update so I am not sure if it will go into a GSOD boot loop.
- I have fixed MFSTools (but have not released it yet) to do a direct copy to large drives (no more limiting the copy to 4 TB and then using mfsadd and mfsaddfix to expand.) The copy from my 500 GB to 10 TB went smoothly and booted it up fine. Recordings were there. Running KS 58 like I usually do after a copy resulted in a GSOD boot loop. Recovered using mfsck.
Consequently, it appears on Bolts running TE4 that TiVo has fixed the bug in the OS which limited partition sizes to 2 TB thus allowing the use of drives greater than 3 TB with a native partition layout but then broke Kickstart 57 and 58 which provides a rudimentary check and fix of the MFS file system.
I have not tested a Roamio on TE4 but I am inclined to think it can handle large drives properly as well. Some one else will have to test that as my units are on TE3 and have been instructed not to tamper with them.
