ptr727 Posted April 25, 2019 Share Posted April 25, 2019 (edited) Hi, I am finally ready to convert one of my Hyper-V servers to Unraid. This machine has 8 drives, in 3 volumes, managed by an Adaptec 7805Q RAID controller. I am using the Adaptec BIOS utility, I deleted all volumes, I unintialized 6 of the 8 drives, 2 drives are grayed out, I can't select them to be uninitialized. When I try to switch from RAID to HBA, I get an error that I need to delete all volumes and uninitialize all drives. Any idea why some drives cannot be uninitialized, or an alternate way to force the switch to HBA mode?? Update: I mounted and booted into the bootable ISO support environment, and found that MaxCache was enabled on those drives. Disabled it, and was able to enable HBA mode. (MaxCache is not configurable from the BIOS) Edited April 25, 2019 by ptr727 Quote Link to comment
Zeppi Posted November 15, 2023 Share Posted November 15, 2023 I'm getting the same error. I don't know what you did to fix this. How do I mount/boot into support Enviro and disable the maxcache? So frustrated Quote Link to comment
