I executed the command "sg_format -v --format --size=512 da0" on a Huawei storage TOSHIBA AL14SEB090N 520-format 900G SAS hard drive, and after a long wait, I successfully obtained a 512-format usable hard drive. （DELL R730xd with a HBA330）
Although this operation successfully made the 520 hard drive readable and writable, the actual speed is halved.
A normal 10k 900G drive has a throughput of about 200MB/s using dd if=zero of=/dev/da0 bs=1m, while this drive, reformatted using sg_format, shows only 95MB/s in actual performance.
cannot accept a 50% performance loss, so in the end, I could only change it back to 520 format and plan to sell it.
