How to identify unlabeled recovery disks?

We have 2 HP laptops, both running 64-bit Windows 7. One's a dv7t-3000 the other's a dv7t-4000. I made recovery disks for both but stupidly didn't label the disks themselves-instead I put them into separate, labeled, envelopes. Then we moved. During the move it appears the disks were dumped into a single envelope labeled 'recovery disks' so now I don't know which disks belong to which computer. Does it matter?

If it does, is there any way I can reset Recovery Disk Creator to make new sets? Both PC's are OK including the Recovery Partition but I don't want to rely on the partition-I want disks I can reload from if I have to replace the hard drive.

Alternatively, is there a way to identify which set goes with which laptop? I can identify the sets because they're on different brands of disks. Any suggestions? Thanks.

 

I believe you can see the creation date from the disc properties? Older set would belong for the older laptop. Maybe.

Disc Creator should be able to reset but how to do that differs from software version to another. Extensive googling might help, perhaps a call to support too.

 

Creation date doesn't help-at least not that I can see. They're very close-like within the same month yet the laptops were bought a year apart. But they don't match the file dates in the recovery partitions either-which leaves me very confused. I'll try HP support but I'm doubtful-the instructions are very clear that you're only allowed to make one set of recovery disks. But maybe they can tell me how to identify which is which. Thanks.
