Subscriber John Paul wrote about an intermittent problem getting his external hard drive to be recognized by his computer:
I have been using a Toshiba external hard drive, 298 GB capacity for about 3 years now for backup.
Recently, however, my Lenovo R61i does not recognize the drive when plugged into the usb port that I usually plug into.
Then if I switch to another port, and after a couple of tries, finally the computer recognizes the external drive. Do you have any idea why the external hard drive is not being recognized by the Lenovo?
Is it a matter of not enough current being generated at the usb port? If so, is there a solution? Any help will
be greatly appreciated.

I wrote back to John Paul to suggest that he try a different USB cable. I think the cable connections are worn or corroded. The hint is that after several tries, it works.
I asked him if this was a full-size drive that gets power from the wall? If so, he should make sure he let’s the external drive spin up before connecting the cable to the computer. And, as above, it could be the cable.
If it’s a pocket-sized external drive, it may be the cable.
Hopefully it’s not the ports on the notebook…

Thank you, Wizard Terry. It was the cable. I would never have thought about that. I guess that what makes you the computer wizard and me the retired land surveyor.
My sincere thanks. In a world of less than ideal people, you shine an honorable light.
Another one solved…
