The forum constantly creates the same topics with the question of what to do with this error in the program log.



=============
Creating GPT-partitioninig
Writing PrimaryGPT at address: 000000000000
Error writing at address: 000000000000 , error: -8 , DATA SND CRC Error(Small ROM Size, maybe) ... Retry #1

Error writing at address: 000000000000 , error: -8 , DATA SND CRC Error(Small ROM Size, maybe) ... Retry #5
Too many errors. Writing has been stopped
=============

The problem is due to the fact that the memory cells in sector 0 have exceeded the lifetime and have a write error occurs.

One solution to this problem is to create a "fake" GP1 partition with a "zero" size.

Thus, the ROM1 is shifted by several sectors and the have a new logical beginning of the section falls on non-killed cells.

This operation sometimes completely kill the eMMC, so use it at your own risk.

eMMC/UFS Health status is calculated by chip and does not depend on create gp1 and anothers action

these values represent the average wear on the cells in the chip.

therefore, there are always very high wear and low wear cells in the chip. their partial mixing occurs when the chip is completely erased and the data is written again.

when any cell works out its number of cycles, it becomes to read-only state. those stops erasing and writing this cells, like 0000000 address cell

gp1 partition is created at 00000000 and next adresses cells and block this cells from use as begin ROM1 address

and nothing else
