"... But, this didn't create any error during the dump process ..."
As it shouldn't. The minidisk whether formatted or not, empty or full,
should be dumped bit for bit. Even on a newly initialized disk, each
track has a Record 0 that must be copied.
Are you doing this on a 2nd level system? If so, is the disk where the
other minidisks reside linked R/O by it?

Subject: DDR Minidisk Restore Problem.
Hello all,
I'm having a problem restoring minidisks which I backed up using
DDR.
Backing them up all on one tape.
I batched up a bunch of minidisks, a quick sample is below:
SYSPRINT CONS
PROMPTS OFF
INPUT 12C4 3390
OUTPUT 181 3590 (LEAVE
DUMP ALL
INPUT 1191 3390
OUTPUT 181 3590 (LEAVE
DUMP ALL
INPUT 12A2 3390
OUTPUT 181 3590 (LEAVE
DUMP ALL
All are going to the same tape. The first mini at 12C4 is
empty. But, this didn't create any error during the dump process and
all the other DDR Dumps complete with problems.
However during the restore:
SYSPRINT CONS
PROMPTS OFF
INPUT 181 3590
OUTPUT 12C4 3390
RESTORE ALL
INPUT 181 3590
OUTPUT 1191 3390
RESTORE ALL
INPUT 181 3590
OUTPUT 12A2 3390
RESTORE ALL
Just the first minidisk restores to 12C4, which by the way there
isn't any records.
Then I get an endless stream of CCW errors on the 181 tape.
The minidisks to be restored are all R/W as an example indicates
below:
DASD 111F 3390 VPDPS1 R/W 8 CYL ON DASD 04B8
SUBCHANNEL = 0039
DASD 1191 3390 VPDPS1 R/W 9 CYL ON DASD 04B8
SUBCHANNEL = 002C
DASD 129D 3390 VPDPS1 R/W 9 CYL ON DASD 04B8
SUBCHANNEL = 0032
To get to the first minidisk I did a:
CP LINK USERA 11F 111F MW
Links are all O.K. no errors on any of the links.
Any thoughts on this would be appreciated.
Thanks.
