So you have this error:

$ sudo blkid -p /dev/sdb1
/dev/sdb1: ambivalent result (probably more filesystems on the device)

This means that blkid detected the metadata of multiple filesystems on the device, and thus it will refuse to do anything because it could be either - and making an assumption could destroy your filesystem.
