I’ve got two 4TB Seagate backup drives on my iMac that are configured as a RAID. Up until a recent OS upgrade, they were working fine. Now, after an hour or so, the RAID unmounts and I get a message that the disk was not ejected properly. I can hear it spin up, then it ejects. Unplugging the USB and re-plugging gets it to re-mount just fine, and I can use them no problem. Could this be an OS issue? I went from OS 10.7.5 to OS 10.9.5 (via 10.8). I have no qualms about going to 10.10, if that might fix the problem. But I’m not ready to go all the way to El Capitan. Would it be worth backing up the backup and reformatting the drives?
A 935 for your time.

I don’t know, but I do want to have the option to have my Macbook themed like that livery.

I used to have a little hack that brought back the rainbow Apple icon for the Apple menu, and you could configure it as a launcher. I stopped using it when I started using Spotlight as a launcher.

Here’s another Mac themed Porsche drag racing an absolutely evil sounding Mustang.

Apple rolled out a new version of Disk Utility with 10.10 to support the Fusion drives and CoreStorage.
By the time you find the answer to what it did to your RAID, you probably would have had time to backup/format/restore your set.

I’m sure it’s still possible, I just don’t know how.

I remember that video. Really great. But I can’t afford a Porsche with that livery, so I’ll just have to settle with my computer.

But I’m not on 10.10. I wonder if something got borked when I went to 10.9. I’ve got my whole iTunes library on the RAID, which I had to rebuild when my last backup drive (a Seagate 3TB) took a shit. I really don’t want to have to go through that again. However, the first time the RAID ejected, I quickly backed up everything except the iTunes. So it’s doable. The 3TB drive ejected itself too, but it was also making the click of death and never remounted.

Oh shit, I read that and forgot that you only went as far as 10.9.

External array, correct? Change the usb cable and if that doesnt help, change the power supply for the external unit.
Also, crack open disk utility and run a disk check and look at the bottom of the logs for anything in red text, thats bad.
Seagate drives are your first issue, they fail super often, I would honestly replace them with WD or HGST immediately if its in your budget.

Yes, external. There is a separate power supply and USB able for each HD.
I will run the Disk Utility and see what happens.
Yes, I was a little hesitant about the Seagate. The 3TB drive that failed on me was a Seagate, but I had also read that the 3TB drives were dodgy, but the 4Tb drives were better. Maybe I’ve finally learned my lesson. I think what I’ll probably end up doing is get two drives by somebody else and set up a new RAID, then use these as single backups on less critical computers.
Thanks.

So, I just remounted the RAID and fired up the Disk Utility. This looks odd. Any idea why the different colors?

That looks very wrong. Shoot me an email. [username]@gmail
You shouldn’t see the disks listed like that. Click on “Verify Disk” after selecting your 4TB RAID array.
