There was a hiss and distortion in the vocals and I couldn't figure out what it was,after reading a lot I remembered I used to get a lot of the error 19 on my flash drive.I tried the cd source in order to see if the hiss was there or not,turned out that there was no problem on the CD but only on the USB. I use a Corsair Flash Voyager 16 gb flash drive.After looking into a lot of things like my gain structure,RCAs etc I finally gave this a shot by backing up the Music on my hard drive and using the following method to flash my drive.

I'm guessing the hidden bad sectors on the disk contributed to this mess which meant the unit was having a hard time accessing all the data,it used to not play some songs too.With this method it rewrites everything in zeros so it's kinda like having a clean slate and then you have a partition that you can format.
Note: When you're done with the cleanup use the HP format tool and don't use the quick format option,use the other to format the drive and FAT 32 as the format with default allocation size.
