This has been discussed and posted in various ways here, but I haven't seen/found a solid solution yet which might be out there.
Has anyone figured out the solution to a USB3 drive ejecting on it's own?
My staff's OWC USB3 external portrable hard drive keeps ejecting during any operation: time machine, Carbon Copy, Lightroom, importing, moving files, etc.
Attached is a screen shot of the warning box that comes up when the drive ejects itself.
The machine is a 2012 NON-Retina MBP.
The drive is an OWC Mercury Elite On the Go drive: USB3 only
We have used the drive, and cable on my 2011 MBP, OSX 10.7.5 with only USB2 on my machine, and it runs perfectly fine under all conditions.
Repaired disk permissions
All Updates for OSX
All updates for 2012 MBP
Taken to Apple "Genius" bar twice. They confirm the failures. Initially blamed the drive/enclousure/cable. Then blamed that there were firmware and other updates that would fix it....which they did not.
YET TO ATTEMPT :
Creating a 10.7.5 boot partition on the 2012 MBP and test that.
Trying a powered external drive on the 2012 MPB
Trying a FW800 drive
Any thing else I am missing? Trying to avoid having to send it into Apple Care and be without a needed machine for week+, and concerned that like others, it won't be fixed anyway.
Appreciate your thoughts.
