Hi,
I found out, that that UEFI firmware (BIOS firmware is ok) is duplicating GPT table to middle of drive, where regular data is and thus making corruption.
It happens during boot process. Problem is in firmware, it is OS (Windows/Linux tested) independent.
On 10TB drive affected drive sector, where GPT is written is 2 353 004 511, on 8 TB affected drive sector is 2 743 151 247.
Look at this it is GPT table. This should not be in the middle of drive (only beginning and end).
You can read this thread, where I discovered that this bug is real and reproducible SnapRAID / Discussion / Help: Strange file corruption
Can someone help me replicate problem on same card?
Thanks
