Hi dep,
warning of its impending doom to a 6-tb drive and thus enduring the process of going from MBR to UEFI,
Had not been stringent necessary! Sufficient had been to partition the new drive with GPT iso MBR. Even the old BIOS-settings had stayed in place.
presume they're there for a reason and before i upgrade i thought i'd try to fix the problem. i searched the archives and found no evidence of a solution.
A few hours ago Stefan Krusche posted a long and detailed overview on this matter. Just search the archive again:-)
Regards Peter.
