Samsung M3 portable drive problem

[ricky2014]

Have had the M3 running ok on my old Asus usb2 system without a problem.

Have just upgraded the mobo to an Asrock H81m with USB 3 but the Samsung M3 , though recognised by the Device Detector and shown in Device Manager, will not show up in File Explorer, be it connected to a USB3 or a USB2 port ?

I can plug in USB2 and USB3 sticks and it does open them ok in file explorer.

Tried the Samasung M3 on the old USB2 laptop and it opens up and R/W to it ok, but try it in the Asrock again and still nothing.

Did try via the Asrock fast usb program but made no difference.

Help please ..

Go into Start menu->right click on Computer->Manage->Drive Management: Make sure your M3 shows up in there and if necessary assign it a letter drive: right click on it->change drive letter and access routes.

Thanks, but found other usb /data problems so ended up having to do a clean install which cured all the problems.

I see, good you got it solved.

Well not quite, seems I had suckered myself.

Had the drive working ok on the old USB2 mobo and had a 2m usb2 extension cable on the drive which I now realise is the cause of the problem with it not working on the new mobo USB3 port.

If I plug the drive into the USB3 port with its original 450mm usb3 cable it works fine at full speed.

Today, got a decent USB3 2m extension cable but even this gave problems and the drive becomes unusable.

Had read tha USB3 was good for 3 mtrs so was just wondering what the limitations on these portable hdds was ?
( did not find any mention on Samsungs site about cable length limitations)
Don't have any other usb devices using much power, could it be a power rather than signal problem ? though don't have an externally powered usb hub to prove the point.
