We’ve been having similar issues with our DroboPro out of the box. I put 2x 2TB in it. At Firmware 1.0.3 (out of the box) i had a steady 30MB/s transfer via USB, but after awhile the second HD showed a red light which shows drive failure. After checking the drive it was fine. We reinserted the drive and after it was added by the dashboard it showed drive failure again. After that we updated the dashboard plus the firmware to 1.1.5. The supposed red light now became green after reboot. All was great til we tested the USB transfer. We couldn’t get more than 5MB/s via USB. We also tested a Tera Station via USB and that went fine. Constant 30MB/s. We tested it in every way possible. We called Drobo’s support center and all we got is that after an update the Drobo had to rebuild its filestructure and that after that was done it would be back to normal. They told us just to leave the PC on. It’s been over a week and still no change. Copying 50GB’s took over 23 Hours to copy. Anyone else have this issue? I’m not getting much help from their support center.
