Basically the link you're missing is the RAID controller suspend seek action that RAID controllers do (amongst other things). There was a reason Apple (back in the day), sold a separate PCIE RAID Controller Card. TLER (time-limited-error-recovery) in NAS drives are purposefully set to drop the data seek in a shorter amount of time than standard hard drives.

Keep up with the TLER request associated with the Mac Pro hard drive system controller. You're basically asking the NAS drives to do something they're not built to do. Everybody is happy now - but it did cost me more for the new WD drives. I found many others with the same experience - sorry, I can't find the forum/thread with the others' experiences, but I learned that my experiences were not unique.Īfter a few weeks of beating my head against a wall, I finally just bought some WD 6TB Black HDDs, put those in the Mac Pro, and put the HGST drives in a NAS. The 6TB HGST HDDs just don't work in the Mac Pro, running anything above 10.6.x (as far as I could tell). If anyone has experience with this or has any ideas, I'd love to hear from you. This isn't the end of the world, but I don't like power-cycling the computer that much. I am still unable to force the 6TB HGST HDDs to mount when rebooting (but they always mount from a cold start). I have tried using Cocktail and Tinkertool System to delay the restart to allow the drives to mount, but it is not working. I have no idea what's going on here - but it's appears to be more complex than simply waiting on the disks to spin up.Īgain - if anyone has any advice, I'm all ears. Furthermore, they can't even be used as a boot device - the machine tries to boot, but then you get the circle with a slash symbol, indicating something wrong with the boot drive (when rebooting. Apparently, under OS 10.6.x, the 6TB HGST NAS drives work fine in the 2010 5,1 Mac Pro. and I'm open to any other advice if anyone has some!Įdit: I was just reading this thread ( ) more thoroughly. (But, i've used NAS drives in the past, with no issues.) This kinda sucks. these are labeled as NAS drives, so I guess their firmware may not be suited for internal use. I'm guessing I just got the wrong drives. strange too - I thought the option-key was a really good idea! That could give it time to spin up ( ).Īnother delaying tactic: "if I boot into Single User mode (holding down Command+S during boot), then wait until all messages have completed, then hit Ctrl+D to continue the boot, /Volumes/RAID6-11TB is properly mounted as intended." (. Not ideal, but if you are only rebooting occasionally, you could try holding the option key and then waiting a few seconds before choosing a boot drive. if anyone has any advice on the 6TB HGST not mounting, I'd appreciate any input. Do any of you have any experience with Tinkertool System and/or Cocktail? Before I make another mistake, I'd like to figure out if this will help or hurt the system.Īlso. At the very end of thread that I linked, someone mentions using Tinkertool System to automatically mount the drives before login, and then using Cocktail to delay startup by 20 to 30 seconds. After discussions with Apple and HGST, no one expects any updates that would fix this issue. so, on a reboot, they are too slow to mount. The basic gist of that thread is that the SSD boots so quickly, and the 6TB HGST HDDs require a little more time to spin up. Turns out, I didn't do my research very well, and this has been documented before: Cold start boot - everything is fine again. Rebooted the computer - the 6TB HGST HDDs wouldn't mount.
Booted the computer, everything worked great. I installed an SSD for the boot drive, and a couple 6TB HGST for data and backup. I am currently refurbing a Mid-2012 Mac Pro (side project) and I fully intend to put this exact card in the mix.I'm doing some updates/upgrades to my wife's mid-2010 Mac Pro (5,1).

Personally, I have used the AMD Sapphire Radeon HD 7950 because it wasn't just compatible with OS X (10.7+), but Windows Vista (which meant it worked in 7 and should work in Windows 10) and FreeBSD as well. Well as the "Mid-2010" and "Mid-2012" Mac Pro models. The other four videoĬards above are compatible with the "Early 2008" and "Early 2009" as Please note that the Sapphire Radeon HD 7950 only is compatible with
Now, according to, there are several more adapters that are compatible: The ones specific to the 5,1 are: Mac Pro (Mid 2010) and Mac Pro (Mid 2012) Apple has an "official" list of graphics cards that are compatible with the Mac Pros (Mid 2010).
