I have a short question concerning my Drobo 2nd Gen: It is filled with four drives (from up to down): 4TB - 3TB - 3TB - 4TB. I am currently running low of protected space – however, the Drobo doesn’t turn one of the two lowest-capacity 3TB drives yellow to replace, but the 4TB drive in the first slot. How is that possible? The first drive isn’t damaged, I assume, as otherwise it should turn red or all the lights should blink (as my data wouldn’t be save anymore).
Does the Drobo have some internal check that the 4TB one will fail soon so that it suggest to replace THIS one instead of one of those two 3TB drives? Or why doesn’t it tell me to replace one of those lower-capacity drives instead?
Also, as I am already asking: I am thinking about buying a Drobo USB 3.0 – my old 2nd Gen Drobo was formatted quite recently so there shouldn’t be the firmware problem when migrating. (I want to put my four HDD into the new Drobo and continue exactly where I have left.) However your FAQs also state that the Drobo shouldn’t be filled more than 90%. Could this turn out as a serious problem when putting the drives from my old Drobo to the new one? Do I have to be afraid that my data will be deleted in the migration process?
Thanks in advance for your help from Germany!
