SAFE TO DELETE OLD TIME MACHINE BACKUP FOLDERS ON UN-REFERENCED EXTERNAL?

Hey Experts:

I currently have Time Machine set to reference external  drive - we'll call it: "DRIVE A" - and I have some really old Time Machine backup folders on a separate external drive - we'll call it: "DRIVE B",  left over from a previous install of OS X.
I want to get back the space on DRIVE B used by these old Time Machine backups.

But I am hesitant to attempt to just "delete" the old backup folders on DRIVE B because I think I read somewhere that Time Machine creates hard links to its backup folders.

Can I safely delete these old Time Machine backup folders that are not on the currently referenced Time Machine disk? Does Time Machine in my system "remember" those old backup folders from an earlier system?

You should be able to delete the old backups on Drive B if you are now using Drive A for your backups.  There are no issues when changing time machine drives to wipe the old one clean.  To ensure you have a clean drive, you could reformat it in Disk Utility so that nothing is left over on the drive that you might have missed.
