PrimoCache only remember disk by disk drive letter?

[MemoChou]

I'm testing PrimoCache in case that i have more than 26 hard drives need to be cached and seems like only disk get drive letters get remembered by PrimoCache after plug in and out disks, other disks that can't be assigned by drive letter were forgotten by Cache Task.
Anyway to fix this? I think it's better to remember it by other things in disks than drive letters.

No, PrimoCache does not remember drives by drive letter. You can cache a volume without a letter assigned.
