Today’s issue is related to one of the most popular portable storage devices ? USB flash drive. A reader asks me this question:
“I have a 4GB Kingston USB drive, it worked fine on my MacBook Pro. But when I insert it into the port today, it can’t be recognized. What could be the cause and how to fix it?”
I have an 8GB SanDisk flash drive. Unfortunately, I don’t use it that often after cloud storage like DropBox and Google Drive show their advantages. Thus, I haven’t personally encountered such issue myself.
As usual, I’d be more than happy to direct my reader to useful resources that are yet to be covered in this blog. Here’re a few I found that could be helpful.
Mac USB Ports Stopped Working? It?s Likely Easy to Fix ? by Paul Horowitz from OSXDaily. He shows a couple of common fixes such as resetting SMC and NVRAM, and other considerations for USB not working on a Mac. Very thorough.
OS X Yosemite: If a USB device isn?t working ? from official Apple support. Well, it’s more like a checklist for you to narrow down the causes, and then fix the problems after that. Also highly recommend.

One last tip: do make regular backs of the data. I quite agree with Paul said in its article that “sometimes a USB device itself can fail, which may have nothing to do with the Mac itself.” Digital device will fail, it’s just a matter of time. But, don’t let that happen before you realize you’ve tons of precious files to be transferred.
Using an external hard drive (or several) is good, but I prefer online backup services like Google Drive. Anyhow, it’s your choice.
