Corsair Voyager GTX ejects on sleep on macbookpro

[willinliv]

Hi,

 

I've just taken happy receipt of a Corsair Flash Voyager GTX 128GB usb stick (SSD in usb stick form). All very well and good speed, however I notice on my retina Macbook Pro every time the computer goes to sleep the device gets ejected (rudely) by the computer, and when I come back to the computer the 'Disk Not Ejected Properly' message is on-screen.

 

For copying across files not too much of a hassle, but running programs/documents from the usb stick could cause problems. And also the rMBP does seem to sleep an awful lot!

 

This does not happen with normal USB memory sticks. I also notice that on the Mac the drive shows up with a hard drive icon instead of what is normally displayed for usb sticks so I'm wondering if the computer recognises this as an SSD over a standard usb stick. Testing on the rMBP on mavericks (10.9.4), and also on a secondary computer running Mountain Lion 10.8.5 and have same thing.

 

Thanks, Will

 

Apple have to say this on the matter:

Archived - Third-party USB hubs may incorrectly disconnect after wake from sleep, causing system instability

This article has been archived and is no longer updated by Apple.

Symptoms

 

Some third-party USB hubs and devices connected though them may disconnect unexpectedly after the computer is woken from sleep. This may cause unexpected behaviors such as general system instability within open applications, or data loss if a connected device was being used to store data from an open document. If a printer was connected through the third-party USB hub, it may not be recognized.

 

Resolution

 

This behavior will only occur if the following conditions are met:

 

The third-party USB hub doesn't support the proper USB wakeup sequence.

The third-party USB hub is connected downline to another USB hub. Note: Apple displays containing USB ports are considered to have a hub, so if you connect a third-party hub to the display, then that USB hub is considered downline.

The computer is woken from an external USB device such as a mouse or keyboard.

The problem can be avoided by doing the following:

 

Connect all USB input devices, such as mice and keyboards, directly to a USB port on the computer or to an Apple display that is connected directly to a USB port on the computer.

Press the power button on the computer to wake it up instead of using an input device that is connected to a third-party USB hub.

Connect USB storage devices directly to a USB port on the computer to prevent third-party USB hubs from affecting them.

Note: Wireless input devices that use the computer's built-in Bluetooth interface will not cause this problem.

 

Note: Third-party developers may change the specifications of their products at will without notifying Apple, so we cannot provide a list of hubs that correctly or incorrectly support the USB wakeup sequence.

For more information on third-party product specifications and features, contact the manufacturer of the device.

bump please. Still getting this in OSX Yosemite, but now I have to also restart the computer!

This might be due to the Flash Voyager GTX being an SSD instead of a standard USB drive. But i'm not sure about it. When the Macbook sleeps, i'd suspect the USB ports also turn off to save power which would "eject" the Flash Voyager GTX, but it does not seem to "wake" when you turn it back on.

 

Have a look at the power settings on the Mac and see if any changes can be made to keep the USB ports powered.
