You use the "md5sum" command. When you download your ISO the website
should also give you an MD5SUM file. For example, look at this
gNewSense page:
The MD5SUM is a code that is generated by doing calculations on the
ISO. The file provided by the website contains the code generated from
a working ISO.
To test your ISO, run
  md5sum my_iso_name.iso
It will print out a line similar to what is in that MD5SUM file. If
your code is the same as the code in that file then your ISO is not

If the ISO is not corrupt then it should write properly to the USB
drive. I am not sure if there is a way to test if the physical device
is corrupted (hardware problem) but you can test the partitions by
using the "fsck" command.
For example, if your USB drive has a partition at /dev/sdc1 then you can run:
  fsck /dev/sdc1
