Disk format 520 to 512 netApp

Hello everyone,

I am trying to format a NetApp 520 disk to 512 block size, but I’m encountering an issue. I’ve been using the sg_format and also setblocksize but i encounter this error for both tools:
“Sense key: Illegal Request”.

I’m wondering if this might be related to some kind of firmware lock or restriction on the disk. Has anyone faced a similar problem or found a solution for this?

Thank you in advance

May the following help you:
