The first clue is there will be a Laser Safety Warning on the drive of some kind. Manufacturers of these drives are required to place notices on the packaging with United States having the notices of: "Complies with FDA performance standards for laser products except or conformance with IEC 60825-1 Ed. 3., as described in Laser Notice No. 56, dated May 8, 2019" or "Complies with 21 CFR 1040.10 and 1040.11 except for conformance with IEC 60825-1 Ed. 3., as described in Laser Notice No. 56, dated May 8, 2019." Within the European Union, the notice of the HAMR drive will have the notice: "Class 1 consumer laser product EN 50689:2021". Refer to manufacturer and model numbers to correctly identify the drive type
