I was in the market for a couple of USB flash memory drives when I came across these two 64GB for about $20. I prefer SanDisk Drives from long ago. Previous drives I had show up as /dev/sr0 and /dev/sd[d] as there was a U3 “device” on the drives. This drive has something similar. I am unable to partition this device to produce boot images for Linux recovery and install medium. Is there a similar tool to U3 removal to free up my memory device to use it as I want?
