Hello everyone, So I have a ASM1061 PCI-E Sata III card I bought about two years ago. It's been in my 5.1 Mac Pro unused for pretty much the past two years. I just got a 1TB Samsung EVO 840 SSD but I can't seem to get these two items to work together. Ironically, I'm pretty sure the ASM1061 card was working just fine two years ago when I had a 128GB Crucial M4 SSD for a short period of time. The SSD is mounted under the SuperDrive, using the Sata extension method. The SSD mounts but I can not erase or partition the drive. I get the following error "Disk Erase Failed, Wiping volume data to prevent future accidental probing failed." I was able to format the drive buy using the on-board SataII connection but once I connected the drive back to the ASM1061 card, it's not working again. It mounts but I am unable to write to it, or re-format the drive. PCI-E Configuration: Slot 4 - ASM1061 card (2 external ports, 2 Internal ports) Slot 3 - Lacie USB 3.0 card (2 external ports) Slot 2 - RocketRaid 622 card (2 external ports) Slot 1 - GPU Could it be that the firmware on the ASM1061 card is no longer supported by the current version of OSX 10.9.4?
