I'm amazed that there is no command line version of 'rm' to delete these, or no information from Apple as to what the command-line version is.
BTW, if your interested, the unique identifier for a given backup is the MAC address of the Ethernet port (not AirPort) of the Computer being backed up.
I don't know what you
are doing, physguy, but only last week I cleared a full external Time Machine backup HD, 300GB, in minutes with Disk Utility's 'Erase' command...
Time Machine needs to know what external HD to backup to. So, with the new, empty, external HD you want to backup to connected and mounted on the desktop, open Time Machine Preferences, click 'Change Disk', select the new, empty, external HD you want to backup to from the list. Click 'Use for Backup'. Then click 'Backup Now' (in the Time Machine menu in the menubar) and go grab a cup of coffee, or two, because a completely new incremental backup set will be generated on your 'new' Time Machine Backup Disk. The first backup being a complete one, obviously, which may therefore take a couple hours. Depending on the amount of data to backup and the interface class you run: FireWire800, FireWire400, USB2, eSATA, 802.11b/g/n, etc.
