Sabrent M501-2902

I bought this to use with a Seagate external drive.While I was able to plug it all up and try to use it, my machine never even recognized that it was there. To be fair I was having to use a PCMCIA adapter which did register on my machine. Installed...

did a test on this. a file 50 gigs took 12 minutes using this so called usb3 and yes it doe's come with a power adapter. Transfered the same files without this so called usb3 adapter and it took 14 minutes. I actually lost time just hooking this up!!!...

My Thinkpad T61 laptop got crashed the moment I plugged-in this ExpressCard into the laptop slot...With Thinkpad T60, it didn't work for four times... then all of sudden it started working... later on, when I plugged-in USB 3.0 HDD it didn't work...!!!...

Is supposed to be Mac OS compatible... not true

Installed properly but haven't figured out how to get it to work period. The 3.0 drive while not spin up.
