Can't restore data off my Zip drives

[KipMc4]

I'm trying to restore some data I saved on 4 Zip drives. It's from an
old PC I'm going to retire that is getting very unreliable.

I thought I ran the Backup correctly and saved the data on the Zip
drives but maybe not.

When i run the Restore, the software keeps asking me to insert the
last disk from the backup. I must have lost it or copied over it
because every Zip disk I try does not work.

So....

Is there a way to at least get the date off the disks that I do
have???

The data is there and the disks are not corrupted. They read fine.
They just are the wrong disk #.

Thanks for your help.
