MP 1,1-5,1 MacPro 5.1 & high capacity hard drives

[guygizmo]

No reason that it should.

I didn't think it would either but someone earlier in the thread said that it worked for them, so I figured I may as well give it a try.

did you try the "tape over pin 3" trick

I haven't tried the tape trick, and might give it a try just in case it ends up working.

However, as I understand it, the tape trick only works on hard drives that won't mount for both a cold boot and a warm boot. My drives will mount during a cold boot every time so it probably won't improve my situation.

Ok yes this is exactly the problem i had with the 10TB WD drive. i need to do the tape trick to get it to mount on cold boot.

but using the mountain app the drive now survives a warm reboot too!

I can contribute and say that I have a 2009 Mac Pro (running 2010 firmware in order to install Sierra) running macOS 10.12.6 and I have four internal hard drives. Three of them won't mount on a warm boot, but all mount on a cold boot.

Disabling trim did not fix the problem.
...... snip

Of the three drives that won't mount on a warm boot, one is a 4 TB HGST drive, and two are 4 TB Western Digital drives.

The one that does work is an almost identical 4 TB HGST drive. There's no rhyme or reason as to why one of these drives works and the other doesn't!

I hope that someday I'll be able to fix this problem. It's quite annoying!

Seems really strange I just took 4x 4tb western digital and a ssd that was connected in the dvd bay out of a machine I sell. They always mounted no matter what type of boot I did it is updated to the 144 firmware no problems like that ever, does not do any good for you really but I did not experience that.

I have never heard of the tape trick or the warm/cold boot problems. Can someone either explain the issue or point me to a thread explaining it? Thanks so much!

Can you explain in more detail how you configured this app to allow your drives to mount after a warm boot?

This whole thread describes various versions of the problem in great detail.

But the gist of it is that some larger hard drives (typically 6 TB or larger) are incompatible with older macs because of a change to the SATA specification that was made recently, and you can fix it by putting tape over a few of the pins on the SATA connector. In this case these drives will not mount at all, either from a cold boot or a warm boot.

The other problem is that some hard drives will mount fine if you cold boot, but if you warm boot / restart the computer then it's as though they're not connected to the system at all. There's no good indication which drives will have this problem. For example, I have two 4 TB HGST drives, one of them has the problem and the other doesn't. The problem is due to a bug in macOS and not the drives themselves as other operating systems have no trouble detecting them. No general solution has been found to this problem so far. (Though I'm curious what krakman is doing with Mountain.)

You can get a demo version free of charge. It works for 30 min then quits i think the website is app engineers .de

In the advanced prefs of the app you click on the desired HD and select 'do not mount on boot'

So on boot/reboot the HD does not automatically mount on the desktop. You need to click on the Mountain app icon in the menubar and from the dropdown menu you can select your hard drive and mount it.

This works for my WD10 TB HD i use it as a data drive so i kust mount it when i need it.

I also tried an app called jettison which works more or less the same.

So this is a bit of make some things better, other things worst -- i.e. now a cold boot will no longer work without re-mounting 2 out of the 4 internal drive manually is my case (and i'd still need to do it in the case of a warm boot). I may be better off sticking to doing cold boots only - at least I don't need to do anything else.

Hi guys. Has anyone tried there 10 TB drives (TOSHIBA HDWG11A)?
Will they work without issues seen in this thread?
I'm also running N300 6TB drives (TOSHIBA HDWN160) without problems, but these seem newer.
Thanks

EDIT: Bought these 10 TB models and they do work with no problems, both in MacPro2,1 and MacPro5,1

Don’t recommend the Seagate Ironwolf drives, I got a 10TB NAS version. It uses non standard mounting holes. You can’t put it on one of the sleds. I had to get a 5-1/4” adapter and put it in the upper optical bay.

Do you know which 10TB HDD still use the cMP's standard mount points?

It seems all high capacity HDD now use the new standard mount points.

Afraid not, that was the first one I bought. Didn’t realize it was a widespread issue. Took me by surprise when I pulled it out of the box. It is also my first 256mb cache drive and I have to say it is quite fast for a magnetic drive. Cut my full TM backup time in half.

 

[Zlobnick]

It's easy fixable with existing sleds and some duct tape Install the screws that match the holes, and fix the other end with an duct tape. Works fine in my machines for a year or two.

I couldn’t bring myself to do that.

Nylon cable ties might be a better idea. Drives can run at up to 60° - temps that can dry out the glue on duct tape.

Going back and reading through the thread and I have to say, sounds like I lucked out with the 10TB Ironwolf NAS. I have rebooted plenty of times now warm between Mac OS and Windows and didn't have a issue with it mounting...

I am looking at replacing the WD Red 6TB I have with a faster 6TB like a WD Black (larger cache, higher RPM), anyone using one and can report on if the mounting holes are standard or has the mounting issue?

 

[s.m.t.]

Well I ordered a 6TB WD Black (WD6003FZBX), will be here today. Will see if it has the same mounting issue.

Are people still having this issue on 10.14 fully patched with the 144 boot rom?

 

[s.m.t.]

Happy to report that the 6TB WD Black showed up fine on a cold boot for me, will need to reboot a few times to see if there is an issue with warm boots...

 

[ZombiePhysicist]

I just put in a 16TB drive. No issues. You need the updated sled with screw holes in right spots.

Seagate 16TB HDD Exos X16 7200 RPM 512e/4Kn SATA 6Gb/s 256MB Cache 3.5-Inch Enterprise Hard Drive (ST16000NM001G)

Seagate brings innovative helium technology to the Exos X16 hard drive. The drive is designed for maximum storage capacity and the hiest rack-space efficiency. Features a 16TB drive in the same 3. 5-inch footprint for 33% more petabytes per rack compared to leading 12TB drives. Helium-enabled low...

I have 2 6tb seagate barracudas farmed from externals in bays 3 and 4, but they are not raided. I have a couple of evos in the other bays and an ssd blade for the system in a pcie slot.

 

[s.m.t.]

So I found the 6TB black I bought doesn't mount after a restart, cold boot is still fine. But the bigger issue is I noticed Time Machine doing a large backup afterwards. The capacity it shows it needs to copy has to be the data stored on the 6TB drive. Anyone else see similar behavior?

 

[atonaldenim]

I just picked up a couple of the popular 10TB WD100EMAZ drives (shucked from the inexpensive WD Easystore / Elements 10TB external drives) for a RAID 0. They do need the 3.3v pin to be taped over to be recognized by the sytem. (Note: it's easier if you tape over pins 1-3 rather than just pin 3, since 3.3v power is not needed by the drive at all.)

But also, I'm disappointed to see they seem to have this warm boot issue, where the drives mount normally when starting up the machine after it was fully powered off, but will not appear to the system if it has been restarted.

Maybe then I will go ahead and build that 10Gbe FreeNAS server I was contemplating...

edit: This is in a Mac Pro 5,1 2010 144.0.0.0.0, Mojave 10.14.6. I also had to buy the OWC drive sleds. I'm curious, if anyone has successfully used zip ties + the original drive sleds, where do you put the zip ties? It seems like they would interfere with the rails sliding in properly.

Would this sled work with Seagate Ironwolf: https://eshop.macsales.com/item/OWC/MPRODBKTLG6/

I got it for the Western Digital 10 & 14TB Ultrastar - a couple of the mounting holes had different locations from the standard Mac Pro ('09) sleds, but the OWC sleds work both with the Ultrastar & older standard HDs. Is the Ironwolf different or identical to the Ultrastar. Is there a pic Ironwolf?

I dont see why it wouldnt work. I dont have an iron wolf but that sled has hole layouts for both the old style and new style. So barring iron wolf using some custom hole layout, it should work.

Yes, I can confirm IronWolf is the same and works fine with the OWC sled. So far, so good.

 

[Plutonius]

I have a single (non-raid) Toshiba 10TB MG06ACA Series 3.5 " SATA drive in my Mac Pro 5,1 and I have had no issues with it.

It does require the different mounting sled for installation.

I'm running Mojave and I use the drive for backups.
