Hi, I am sorry to tell you that we have no solution for this you could only try to use Seagate tools to do this.   Did you have any other questions?   Regards Martin
I have a pair of 2.5" SAS DL1800MM0159 (512e) that I want to convert to 4K because a vendor sent some additional drives in the 4K variant instead of 512e by accident, and it will be a lot less hassle to the vendor to restock and ship new drives if I can convert these two drives to 4K to match which would also suit me. I've tried SeaChest_Format (with the SeaTools boot disk) and also openSeaChestFormat with no joy SeaChest_Format -d /dev/sg2 --setSectorSize=4096just fails with "Failed to set sector size!" and also --fastFormat=[0|1|2] --formatUnit=4096just fails with "Format Unit Failed!" unless I use the "current" format size, then it works (and takes all day) but doesn't help because it's still 512 I've also upgraded firmware on my old drives from ST58 to ST5A (with an unlisted download from the dell website [URL] but all without success [IMAGE]claims to support 4096 I think it ought to be possible because the ST53 firmware download page ([URL] has as a listed fix: -Fix an issue where host block size is not changed after fast format Is there a special Dell tool that I am supposed to use? Or is it safe to use SeaChest_Firmware and flash some seagate-released ST* firmware instead of the Dell firmware? Anyone know where I can get any such firmware? Or is it impossible for me to make this conversion to 4096? EDIT: The 4K Toshiba drivers that the vendor sent are recognized and work fine as a group, they just won't combine in RAID5 with the 512e
How do I convert DL1800MM0159 (512e 4Kn) sector size from 512 to 4K on T630
