I have a couple of Sandisk USBs which do not get recognised on the screen by any linux I have tried.
They do show up in dmesg, dfisk, etc.
Any ideas what I can do to get these back please?
I understood that the USB interface was in a hardware chip and reports a description of itself. I see this in the dmesg printout.
Can I just try to make the filesystem type decimal(hex?) 83 for linux and then maybe it will allow gparted to write a partition table?
Thanks for any help.
Paul

however when I try to use gparted to write a partition table I cannot do it.

So, I see this looks OK but cannot be mounted. Error message is the same as the previous one.
