I have a problem, caused by me. I just bought a NAND usb stick 2 TB which worked out of the box.

I tried to copy 36GB into it. That of course took too long so, I put my laptop on suspension to not interrupt the process, (that's what I thought). The process stopped of course, and I tried to delete half copied files. This also took too long so I closed the window and tried to delete the from command line which also took to long so I stopped the process and pulled out my usb stick.

Since then my stick is not recognized.

I can see these on journlactl

With lsusb I have this

I think 

Bus 003 Device 006: ID ffff:1201

is the records for my USB.

I have Centos 7 with kernel 5.4 and xforms as window manager.

I don't know what to do.

I am sorry to inform you that the only 2TB USB flash drive available in 2020 is the Kingston DataTraveler.

All other USB flash drives indicated with this capacity are a fake product. They will usually only have a capacity of less than 128GB (or way less even), and trick the OS into thinking they have such a capacity. They will become unwritable once past their true capacity.

I highly suggest getting a refund for your purchase.
