I had a Z8 for many years and attached a external HDD for recordings. Now I bought the new Z12 ultra and wanted to attach that same HDD to it. But it doesn't connect. Under device preferences - storage - removable storage I see the HDD but it says safely ejected.

Did you formatted the HDD with NTFS again before connected with Z12?
-
Hi Sam , no I didn't. I thought there would be no need to because it was formatted NTSF in the beginning and it worked well with the Z8 and without external power. I can format it again with a friends laptop ( I have a macbook) but would loose all the recordings on it.

Did now a format with exFAT on my macbook, (don't have a windows computer, so NTFS is not possible) lost all previous recordings from my Z8, but Z12 recognises the HDD finally.
