I have a serious issue with my Moserbaer Pen Drives. I had purchased a 4 GB Moserbaer pen drive (Red and White dual color). It was unable to store high volume video movies. I mean the video gets copied but gets corrupted instantly. Sometimes the videos get paused while being played if in case it did not get corrupted. So I had to replace it at service centre. Meanwhile I purchased an 8 GB of same Moserbaer pen drive from Flipkart. I never experienced a single problem out of that 8 GB pen drive. However the replaced 4 GB pen drive of Moserbaer works fine initially but now it is showing same defects with videos and I am just unable to understand why it is happening again. Please guide me here.
