Please umount and try
mount /dev/sdc1 /mnt -t reiserfs
if it mounts: ls -l /mnt
It fails with
mount: /dev/sdc1 already mounted or /mnt busy
If it is umounted, and mount -o ro /dev/sdc1 /mnt fails
try dmesg to see what did kernel say why it could not mount it.
This also fails with /dev/sdc1 already mounted or /mnt busy
dmesg has no error related with mount see what it returns (where else cld
the kernel be logging?)
