Other Help Topics :: Only a USB is seen many others are not

I've been able to see that DSL restore the backup.tar.gz from an old 128 MB USB pen.

I copied the file backup.tar.gz on
256 MB FAT formatted USB pen (*)
256 MB FAT32 formatted USB pen (*)
1 GB USB pen
160 GB external USB HD

But none of these was detect.

(many other 1GB pens in the past.)

Why?

Thanks, Fede

Check partition table consistency with fdisk -l

the 256 USB pen inserted from start

[/home/dsl]# fdisk -l

Instead the (working) 128 USB pen inserted from start

Weird enough, one time in the middle of the X session I inserted the pen of 256MB and it was detected as sda1: it never have happened again after that time. I swear.
