That only prints out the partition table. I want the kernel to recognise it too. ie fdisk -l says /dev/sdb1's there, but ls /dev/sdb* only says /dev/sdb.

Yes /dev/sdb is the drive

You can't see the internal drive partition under /dev/sdb*

Please tell us what are you trying to do...?

What partition type on your pen drive are you trying to read...?

Thank you

It's odd to partition a pen drive, but nevertheless, the command you looking for is `partprobe`
elart.it: The kernel keeps an internal list of partitions on which it operates. This list is once built at startup and not modified later on without explicit instruction. When you change the partition table of a drive while running, the kernel doesn't notice that change - until you use partprobe.

Can you help with this problem?
