MacOS: Can the TimeMachine HDD's be used on a different PC?

I bought a replacement MacBook, and inserted the 500BG SSD from the old machine into the new one. I also have a few backup HDD's which I used with TimeMachine on the old machine.

Can I safely use those drives with the new PC? The new MacBook Pro is of the same vintage as the old one, and I moved all configurations to the new PC by way of swapping the old SSD into the new PC.

Thanks.

The HDD are for TimeMachine use only and they are not formatted in a disk format of OS X.

Do you want to use them by putting the HDD in a USB case and directly attach then to the Mac Book Pro?

If yes, you need to reformat the HDD.

Sorry not to have said, I want to use them with TimeMachine on the new MacBook Pro, to back up the same SSD, which was formerly in the old computer.

I am just afraid to plug it in to find out what would happen.

It should still work. The old data will remain, but you can manually go and delete that to make room if necessary.

I have no need to delete it. It's the same data.

I was just worried that Time Machine would see the different machine serial number and consider a new backup and shred the old data.
