USB3 not working on my Retina MBP

I have a timemachine backup that is on a USB3 Toshiba 750 GB drive. Obviously ive been using it at USB2 speeds, and it works fine on other macs, but when I plug it into my retina MBP, the HD will spin at low speed, but it never fully loads. For those that know these toshibas, the light on it stays blue instead of turning white.


I have tried mounting it via diskutility, but to no avail. Anyone have any thoughts? It has a fair number of things I need to transfer over!


Thanks,


- Jeremy

...I bought a new MBP Retina last week and none of my USB 3 Harddrives are recognised by it. (3 different ones) I went to Apple Support today and they first blamed the harddrive but then we tried it on all their Retinas and it doesn't work on any of them...

Are these bus-powered drives or do they have their own power supplies?

Hi, The WD definitely works on my MBP 13" and on iMac but I haven't been able to check with a 15". One of my other harddrives that doesn't work is a Seagate GoFlex which also works on all other computers so I'm pretty sure its the Retina

I tend to agree, 3 drives and 2 brands is pointing at the Machine not the drives. But it is not nornal. I would test that your drives work on a Non Retina machine (test the Seagate as well)

Hey,


So I actually was the priginal poster in all this...and basically it comes down to this right now


It seems to be the retina. Wall powered USB3 is no problem, Bus powered USB3 is hit or miss.


I do a lot of video production and work with a lot of different drives with different people, and its just hard to say for sure what might work/not work when.


I have them mount fine as USB2 with other machines, but nothing since Apple introduced USB3..and we tried on macbook airs, iMacs, etc. Some bus powered USB3 just wont show up, or at best, shows up as USB2.


Personally, ive found that all the other retina attributes make up for that..I've rarely REALLY needed usb3, and I suspect a software update in the future will make a difference.


Cheers!

FWIW, I've been using a couple of Toshiba 3TB externals with a rMBP 15" 2013 with no trouble and full USB 3.0 speed. I just tried a WD MyBook Essential drive and that worked properly too. Only variable may be that I used the Toshiba cable with the WD and that none of the externals are bus powered. I've also found that while a USB 2.0 device resets the Mac's USB 3.0 port to 2.0 and sees a subsequent 3.0 device as 2.0, the port resets itself to 3.0 speed during the transfer (watched it in Activity Monitor). With all the complaints I've read since this thread started, I've been surprised at how well the combine 2.0/3.0 port works.


Following StuartOnLine's link reminded me of the other issues, so, both right and left side ports work and the ports support booting from external boot drives at USB 3.0 speeds, which gives some of the flexibility of the Mac Pro.

I had this same issue when I purchased the 15" Retina Display in June 2012. In fact I ended talking to one of the Techs from Apple Hqs after I posted this issue in the Apple Forum. They actually called me at home to discuss this issue. We did end up resolving this issue. See this Forum for the results we came up with.

Ended up doing a Tremninal Control input change.


Since then all of my USB 3 drives have worked with not issues.

I finally managed to get a Seagate Backup Plus 1TB drive to always work as USB3. I reformatted to Mac GUID, and use it for backups and data. I have also used a 2.5" bare drive off of the Segate adapter and it runs as USB3. Making sure to plug in a fully compliant USB3 drive and cable, not USB2 drive first does apply.

I still have issues with a Newer Tech Voyager Q (quad I/O) using USB3, firmware is bad. I use the FW800 or Ethernet port instead. Those work fine.

Good luck, Greg
