DJM350 Recording Issue

Heeello!

So, I'm after any advice on this f*kin horrible problem i have, i'm recording a mix via USB through my mixer 'DJM350' because it has a USB record function in the top right side, everything is great VDJ runs lovely and smooth and no hiccups, BUT when i take out the USB and listen back, there is horrible noises everywhere and it litrally speeds the tracks up x10 faster and then after so long goes back to normal before doing it again?

I've tried multiple USBs and have also tried a desktop PC & 2 other laptops, (each have a quad core i8 processor) to no avail.

I've posted a link to the noise, if anybody could just give it a listen and see if you have ever heard of this problem before you'd be a massive help!

Everything has the latest firmware too.
