External drive will not mount over Firewire
OWC Mercury Elite Pro enclosure
SSD via SATA
MacPro 3,1 running El Capitan
Trying to repurpose an older external drive enclosure for an SSD. Here are the steps I’ve taken so far and the results I got
- Connect via FW400 on back - no mount, stalls bootup
- Connect via FW400 on front - no mount
- Connect via FW800 on back - no mount, stalls bootup
- Connect via FW800 on front - no mount
- Connect via USB on PCI expansion card - mount successfully
- Install SATA HD with same configurations tried above on SSD - same results FW fail USB win
- Connect SSD to old MacBook via FW400 - mount successfully
- Connect via FW800 to MacPro, boot into Recovery Mode, run Drive Utility, FW drive is recognized
- Recovery Mode, Drive Utilty, repair boot drive, repair FW drive
- System Profiler - FireWire page throws error, no drives listed
- Reboot while deleting NVRAM
So I can assume the drive and enclosure are functioning properly. The issue is with my FW ports/buss on the MacPro.
I have 3 other FireWire drives and a FireWire video camera connected full time, although the often powered off. All mount/work flawlessly and have done consistently.
I have 3 other USB drives too.
I have the spare FW800 port and when I needed to add an additional drive to my system I wanted to make use of it, rather than adding another device to an already busy USB buss and FW400 buss.
Any ideas how to get this one drive working -OR- identifying the issue with the FW800 buss with a definitive answer. I’d love it if the FW buss can be reset/cleaned/restored or whatever. Please I’d be very grateful.
Thanks
