normal sata-usb should be ok. seagate/toshiba sata-usb will eat
sectors. some gigabyte dual-bios motherboards will eat sectors (with
disk HPA function).
In the early days different vendors made different capacity harddisks.
But at some moment, maybe 250GB or 500GB, suddenly every vendor made
the same capacity harddisks. It's a mystery to me. who decides the
disk sector numbers? why 2TB disk capacity is not double 1TB, 8TB not
double 4TB? capacity is different for sd-card and ssd, but harddisk
capacity seems normalized at some time.
