Ultra fit 32gig usb doesnt play in car

I bought a 64Gb version to backup my cd’s to play in my new Nissan. It took a long time to rip my CD’s so I was looking forward to many hours of music on the road. However I quickly started to experience songs stopping for no reason. I also noticed that it was running ridiculously hot. btw I have 30 years experience in fixing computers as it’s my job. This drive runs way too hot, and in my opinion it’s a fault in the design. Certainly I have never come across a computer device that runs this hot.

Anyway I though I should backup the sandisk to my PC and soon found it kept crashing therefore I couldn’t backup the files. I am having to start all over again so really hacked off with sandisk. I wish I had ripped the cd’s to my hard drive first but I just didn’t expect the sandisk to be a problem.
