Is USB 3.0 expresscard adapter compatible with mac?

I have a new 17" macbook pro with expresscard slot.  I purchased the usb 3.0 on expresscard adapter for my goflex drives and it works on the pc side of my mac, but not when I'm booted into osx.  It never claimed to work with mac, but before I give up ... is it supposed to work?

It won't be the 3.0 doing it, many folks have issues trying to use these between Windows and Mac O/S at the same time, if you can partition it half and half it may work as two drives in one but with half the capacity for each O/S if you get what I mean.

 

So try partitioning it and format one half NTFS or FAT32, and the other half the OSX format.

Apple does not yet support USB 3.0 so it very well could be the 3.0. For a list of acceptable and supported connections for free to visit http://support.apple.com/kb/HT1151  Called USB and FireWire Quick Assist  and can be found at the Apple page, does you which devices will work with your Mac with tips for troubleshooting. Good luck hope you find was causing the problem I still haven't and I'm still looking.

Guys hope this thread is still alive !!

 

Since OSX Mountain Lion brings in native USB3.0 support, did any one try the seagate USB 3.0 upgrade cable package with express card adapter?

According to seagate KB (http://knowledge.seagate.com/articles/en_US/FAQ/217951en#13) ,
The Express card Adapter would provide USB 2.0 speeds in OSX as there was no USB 3.0 support, but since now we have USB 3.0 support does the adapter work and give better speeds than before .

I know the limitations of Express card bandwidth, and that it cannot give full USB 3.0 speeds for PCI based express card but a USB 3.0 support means a definitely higher speed for my 1TB seagate GoFlex Freeagent HDD.

Awaiting Reply !!


P.S (No, eSATA does not work for my HDD. Sadly )

THIS IS NOT COMPATIBLE WITH MOUNTAIN LION

 

:smileymad:

 

Ive been a fan of Seagate harddrives but eversince I got the GoFlex drives I cannot use the exprescard on my Mac (Macbook Pro 17-inch). I found a patched Lacie driver which works but keep getting a kernel panic and it's unstable.

 

I have no idea why Seagate doe not release a simple (ONE FILE KEXT DRIVER) driver for the mac for the GoFlex Express Card. Come on Seagate its one bluddy file - Lacie, Caldigit and Trendnet did it - why cant you.

 

I am seriously considering going to Lacie or Caldigit drives and ditch all my Seagate drivers.

 

NOT HAPPY WITH SEAGATE AT ALL ATM.
