Thanks for all your inputs.  But from most of your replies, it appears that 
we can no longer recover the data on the tape without the services of a 
recovery specialist.  By the way, the tape labeling failed because of the 
write protect. However, it appears that the physical write protect switch 
won't "really protect" us from accidents in the sense that it 
doesn't "completely" write protect the whole tape contents. Which, I think 
should not be the case, because then the physical write protect switch 
would be useless.  And because the label failed, I would think that only 
the "headers" (or something like that) was damaged and that there might be 
a way to scan the contents.  Hopefully someone out there has some fancy 
command I can run. Fingers crossed.

Seems like I posted the output of the wrong tape.  Here's the correct one.

X:\>mt -f \\.\Tape2 status
\\.\Tape2:
        Media Capacity  = 37.25GByte
        Media Remaining = 0
Byte
        Media Blocksize = 0
        Media Partition Count = 1
        Media is write protected
        default blocksize = 65536
        maximum blocksize = 524288
        minimum blocksize = 1
        MaximumPartitionCount = 1
        Partition = 0
        Logical block position = 0
        EOTWarningZoneSize = 0
        CompressionEnabled
        ...

Here's an output of the scanner command.
  
X:\>scanner -mv -f 3 -r 2 \\.\Tape2
