Hi, I have an old Drobo DRO4D-D that has been working great for many years but now the unit won’t mount and I get solid red lights up the side, solid blue lights all along the bottom and a solid red light for the power light. As it won’t mount I can’t run any diagnostics on it.
I run it to my 15" 2017 MacBook pro, running High Sierra 10.13.6, via usb. The 2 firewire ports burnt out years ago so have only had the usb port to work with but it worked fine for years.
Also I have the chance to pick up a Drobo FS NAS but I don’t know if I can just transfer the drives to this other unit or not and I can’t update the firmware on my unit to the most recent update.
If anyone has any tips I would be very appreciative.
