Same to me here, but I also noticed that the time taken to open the disk is proportional to the size. So a 1 Gb USB drive takes a few seconds (10 or so) and a 250Gb USB drive takes about 10 minutes to mount. Using HTOP I could also notice that the kernel process is using 100% of the CPU while I cannot access the drive. When it stops being at 100% I can start accessing the drive.
