Having trouble getting your Seagate GoFlex external HDD to power up? Assuming everything is plugged in as it should be, try this. Grab the USB connector (at the computer or hub, not at the drive) and give it a teeeeny wiggle so it starts to slide out just a bit. Monitor the drive carefully. Did it just spin up? You’re welcome.
My drive works fine with my home desktop PC and a laptop. One of these machines has USB3 and the other does not. I couldn’t for the life of me get it to spin up on my girlfriend’s iMac, or on her PC at work.
These units exibit an unusual behavior in that the drive will not spin up on wall power alone. It must be plugged into the wall and a USB port both or it will not turn on. Try this yourself. Unplug the drive and power it down completely, then put your ear close to the enclosure while plugging it into only wall power. You’ll hear a faint chirp and then nothing. I believe the drive is sensing no USB connection and remaining in sleep mode — probably an effort to stay “green” and have the drive intelligently go to sleep when you turn off your computer.
I verified that this is strictly an issue with the cable by swapping it for another USB3 cable I have from a different device and manufacturer. Indeed, the GoFlex works great no matter how hard I plug it in now. Seagate really needs to visit their cable supplier.
It may be reasonable to assume this is an issue only with their USB3 drives, and if the same company provides the USB3 cables for all their externals, it’s reasonable to assume that this could affect their Ultra-portable, Turbo Performance, and Slim Performance drives, too. Basically anything that uses the same cable.
