Narrative:

All aircraft had 'data' flashing in the data block; so I called to verify the aircraft positions. Apparently pdx approach hands off aircraft too soon or stars performs an auto hand-off too soon and eram can't correlate the aircraft position. Recommendation; have portland approach wait 20-30 seconds before attempting hand offs to the center to allow eram to catch up.
