Yeah. Someone tripped on my external hard drive USB cord while it was plugged in. It gave me the generic "Please unplug device properly next time." or whatever message.

Not, after rebooting the mac book pro, unplugging and replugging everything, it is still not detected. Not even under DiskUtility.

Please help? lol
 
Other computer can detect it. Different USB cable did no good.

No way I can make it force detect it? Or make the mac forget all the devices I accidentally unplugged?
 
Do you use the dual-usb plug cords with one end going to the HD and a split end with two USB ends, one for power+data, and the other for backup power? it may not have enough power.

Examine the USB port you were using on the MBP for damage. Try the other USB port. If it still doesn't work do the following:

1. SMC reset
2. PRAM reset

See if this helps.
 
No idea what either of those resets are, my apologies.

It uses one cord for power, one for USB power, both are plugged in, it is on.

Another device (wireless mouse) works in the USB port, and the ext HDD doesn't work on any of the USB ports.

So, what are those resets?
 
The SMC reset fixed it. Thanks greatly. Now I have it set up to my router as a time machine thingy. Thanks again guys.
