    So with a new Western Digital 1 TB hard drive put into a external enclosure connected by eSATA which is to be better format type, MBR or the GPT? The reason I ask this is that I have 2 computers set up, one is a 2012 Dell with Windows 7 and has a MBR drive, and my other store built last year Windows 10 system which has 2 drives both with the GPT since that newer computer uses the UEFI as well. So if I want to share it between these 2 PCs will it work out okay formatted the newer GPT, or are the 2 types not at all compatible? I plan to just use that drive for storage as ntfs, and for backups. Okay thanks.

    It will work either way. Unless you want to delete everything one the drive and start over, just leave it as is. The only way to change a storage drive from mbr to gpt is by deleting everything off of the drive. A system drive can be changed in win10 however not a storage drive.

    Okay thanks, and I did find a MBR to GPT conversion tool and GPT to MBR available online which keeps your drive data and O/S. Here is one of them, as well as some of the better partitioning tools can do that conversion safely also; https://www.diskgenius.com/partition-management.php .If I install a newer Linux such as the Mint 19.2 onto that new hard drive in the external enclosure, after formatting it as GPT with my Windows 10 newer system, will it be okay with selecting the GPT type during the install?

    Yes, there are third party tools however you may find that they do not do the job. Using the native windows tools, only a system drive can be converted. In any case, IF there is anything you want on the drive, be sure and back it up prior to using any third party tool.

    To answer your question, when doing a windows install it is best to have the disk blank ie no partition info, no mbr/gpt ie nothing on the drive. Let windows setup install in whatever manner it thinks best.
