Others have basically said the same thing I'm about to, but I'll phrase it differently along with another reason:
If the drives have data on them that you want/care about in any way/shape/form (even if just for archival purposes), then yes, you absolutely should hook them up and get the data off them ASAP.
The reason has to do with the fact that the magnetic media of platters, over time (especially long periods of time) begin to degrade. Bits become harder and harder to pull off the drive, even with proper ECC regions per sector, I/O becomes slower, and so on. Eventually the magnetic attributes degrade altogether and stuff will be lost.
So yes, I recommend you get the data off the drives and put it on something that might last you longer -- with drives that size, try CDs, DVDs, USB flash drives, or all of the above. Bare minimum
(especially for how small capacity-wise the drives are), take a raw disk image of each disk (not partition, but disk) and back that up somewhere.
I can tell you a short story about me doing something similar to the above, if you want, and how what I did brought a really big smile to an old colleague/co-workers' face almost 15 years later. Just let me know.--
