Hello,
I run the command [it took some time] and the result was as follows:
# fsck.reiser4 --check /dev/sdc
*******************************************************************
This is an EXPERIMENTAL version of fsck.reiser4. Read README first.
*******************************************************************
Fscking the /dev/sdc block device.
Will check the consistency of the Reiser4 SuperBlock.
Will check the consistency of the Reiser4 FileSystem.
Continue?
