With large capacity tapes an erase can take a long time. Listen to the drive or look at the activity lights to tell that it is working.  If so try letting it run for a few of hours and it should finish.

When you interrupt the erase operation it will probably do a rewind, which will also take some time.

I don't do use erase any more for preparing tapes, just retention.

If the drive is indeed locking up, look at SCSI issues next - termination enabled, termination power, sync vs async operation, channel speed, etc...

Also make sure you have the latest bios/firmware for the controller card and tape unit.

Also get the sonytape test utility and play with that for clues.
