Make USB flas drive Read Only
Hi guys, I have a unique situation that I could use some help with. I want to be able to save files and folders on a USB flash drive that can not be erased. The tricky part is, this is to be read by several different models of sewing machines for embroidery use. Some sewing machines have to write something, i don't know what, to the flash drive in order to format the drive to work with the machine. The only solution I have heard of that may work is to partition the drive and then flip the removable bit to secure the files on one partition. None of which I know how to do. I can purchase a flash drive and have my data pre-loaded and then locked from several online USB sellers, but none can guarantee it will work, and the start up costs are something I can not afford to gamble with, and none of the companies I have contacted are willing to sell me a prototype. Help Please!
