Review on 💾 Western Digital 4TB WD Blue PC Hard Drive HDD with 5400 RPM, 6 Gb/s SATA, 256 MB Cache & 3.5" Form Factor - WD40EZAZ by Ryan Lindstrom

I tried formatting 6 times with different connection types: 2 power supplies x 2 drive bays with XFS, + 1 time with SATA, + 1 time with ext4. It is known that SMR is not suitable for long write operations as it doubles work in itself. It's known to be broken for XFS, which is what I found, so I tried ext4. Even then, the format failed after an hour. Something like this happens every time: #mkfs.xfs:mkfs.xfs: error writing libxfs_device_zero: IO error#mkfs.ext4: group table mapping: finished writing inode tables: finished creating log (262144 blocks) :done Writing superblocks and filesystem accounting information :mkfs.ext4: I/O error writing and closing filesystem It's just past the return window, so I screwed it up.
