Hi Timo and Rafael, I'm not a sysadmin, but just a hobbyist who ordered a used SAS Hitachi hus723030als641. I'm experiencing the same thing (`blk_update_request: protection error` and `blk_update_request: i/o error` on Archlinux and Ubuntu). Also, in Windows 10, I am able to view the drive, but have trouble formatting it.
Does this have anything to do with the read protection on the SAS drive? I was searching around and found the `sg_format` command. Running `sg_format /dev/sdX` reports that the drive has read protection on. I'm not entirely sure what that means, but I'm currently trying to format the drives with `sg_format /dev/sdX --format` (which, if I understood the manpages correctly, I believe will unset the protection bit). Will let you know in a few hours when it completes. In the meantime, do you know anything about whether this SCSI protection level business is related to the error at hand? I don't understand it very well and I can't seem to find much useful information on it on the web, so any input would be appreciated.
