[nvmewin] Tested LBA size ?

Hi Olivier,

Windows OS only supports 512b and 4K LBA sector sizes. Using any other sectors size is untested for the Windows OFA NVMe driver... and results will be undefined and may lead to issues. 

Thanks,
Ray

Subject: [nvmewin] Tested LBA size ?

Hello.

Does anyone already experience to use a NVMe SSD with a namespace defined with a  LBA size higher or equal to 8kB.
I successfully tested a device with LBA sizes of 512 bytes, 1kB, 2kB or 4kB.
But when I use a LBA size of 8kB, the NVMe initialization is good but I can not see any read command access to drive after.
The controller is enable but the host does not perform any access expect for CSTS read.
My host page size is 4kB.

Any idea (bad configuration, ...) ? I don't understand what is expecting the driver.
Thanks.
Regards.
Olivier.
