Bests & Worsts Reviews from Amazon

I got a defective unit. It took me awhile to figure it out because it works on some devices but not others. Here at the office, it is readable on 2 PC's but 4 others say it's corrupt. I thought it was the PC's USB reader but have discovered that not to be the case. The event log on the USB hardware manager shows 4898 warnings and errors stating that the samsung hardware configuration won't load. The errors were dated 5/16/2018. This product was delivered to me on 7/7/2018. Tried reformatting the drive multiple times but no go. Return period ended 2 days ago. Waste of $25!
