    This external western digital hard drive installed in an enclosure, is connected with eSATA to a 2012 Dell XPS desktop computer. This hard drive is fairly new as I got it early this year. And so when I try to boot up my Mint 19.2 on a 50 GB partition formatted by the MBR method not GPT, it gives error; "kernel panic not syncing- VFS: unable to mount root fs on unknown block (0,0). And I am booting other Linux installed on a internal drive okay with the Windows 7. And a 2ND error which sounds alike; " attempt to read or write outside of disk hd0. So is possibly a defective hard drive or does it need a full reformat? When I run the sudo fdisk -l from a good booting other Linux, it does show all 8 partitions okay except for the sector size; ( other drives have both listed as 512 bytes ), this drive has;
    Sector size (logical/physical): 512 bytes / 4096 bytes
    I/O size (minimum/optimal): 4096 bytes / 4096 bytes
    So why is that?
