Title: Any type or manufacture HDD that WON'T work on a Pro Vision 4k Solo?
Post by: caseyjones on February 09, 2022, 03:24:20 AM

Are there any HDD's by manufactures and/or type/model that aren't recommended or won't work on one of these for any reason?

Android uses a 32-bit register to address sectors causing the infamous HDD 2 TByte limit with 512 byte sectors. Using the 512e trick one can access just over 16TByte with 4K Physical sectors emulating 8x 512 byte Logical Sectors hence 512e format.

The unrelated cluster size is how big the OS writes the data single I/O in multiple logical sectors (up to 32K allowed but may increase slack with many small files on it).

But I may be mistaken as I see 18 TByte and 20 TByte drives advertised as 512e compatible. How they do that? Do they assume W10 64-bit OS using a 64-bit register for that? Will stick to max 16 TByte myself till I am convinced it can and will work flawless with Android 32-bit.
Some reported these drives working but others signaled disk errors found when inserted into a W10 PC next. Reducing the used partition size to 16TByte stopped those errors being seen.
Somebody tried finding the exact limiet: He claims it is 16.770.000MB (Win Explorer shows 15,9TB) which makes a lot of sense to me.

Thanks for the reply.

The drives I was talking about are only 4TB.
I thought I read something about WD's NASware 3.0 (or similar) drives having a problem.

Don't use SAS or 4Kn type of drives. In general the cheaper the type the better for a media player. Performance is not an issue so slower is better (less heat and less noise).

The drive I bought is a WD 40EFZX 5400RPM "Red Plus" it was $85 which isn't expensive (I wouldn't of bought a 7200RPM model).
