| retail-kit | identity | disputed | Seagate's product manual 100323825 lists the ST3300631A as a Barracuda 7200.8 PATA model; the Icecat data sheet and the 2008 Amazon-derived description call it Barracuda 7200.9 | ^icecat |
| | identity | unknown | Country of origin; the old Barcodepedia "Produced in Switzerland" line was generated from the barcode prefix | ^archive |
| | identity | unknown | Production status: the maker's current site no longer serves the 2006 retail range page, and no dated end-of-life notice was located | ^seagate-retail |
| retail-kit | relationships | disputed | The GS1 prefix owner rests on Seagate being the brand owner of two kits in the 0763649 block; no source names the prefix holder or its length | ^seagate-retail |
| | markets | unknown | Other markets: only US listings were matched; an Amazon.com listing exists without a price | ^amazon-us |
