Oh, yes, indeed.  Nevertheless, the first two messages:

> tar: /home/share/D60/725CANON/CRW_2526.CRW: Cannot extract -- file is 
> continued from another volume
> tar: Skipping to next header

are perfectly in order: they indicate that tar is skipping the partial
member.  The fact that it does not find any subsequent member indicates
that CRW_2526.CRW is continued on volumes 147 and 148.  To compare,
here's what I get running tar-1.16.1 on one of my multivolume backups:

$ tar -xMv $(seq -f"--file=arc/b%g.tar" -s' ' 157 292)
./radwtmp
tar: ./radwtmp: Cannot extract -- file is continued from another volume
tar: Skipping to next header
./TAGS
./build.emris
tar: Error exit delayed from previous errors
$ ls
TAGS  build.emris

Here, the file `radwtmp' was occupying volumes 157-291 and, partially
292.  It was therefore skipped.  Other two files were found on vol. 292
and were extracted.

Please, verify whether the file in question spans all three volumes.

No, I don't think so.
