We decode only what the manufacturer documents. There is a large body of community knowledge about the undocumented segments above, much of it probably right, and none of it published by Toshiba - so it does not appear in this table. A reading nobody can check does not belong in a column headed “what it means”. Grammar reference: Toshiba - enterprise HDD model nomenclature.

A manufacturer part number does not imply a manufacturer warranty, and this is where part-number buyers lose the most money. OEM stock, integrator pulls and gray-market units all reach the market under the maker's own numbering. Retailers selling them sometimes state plainly that the manufacturer warranty is none; others simply do not mention it, which is not the same as it being covered.
Coverage attaches to the individual unit and its serial number, not to the part number. That means the only reliable answer comes from the manufacturer, about the specific drive you are being sold.
Ask the seller for the serial number before purchase, then enter it in Toshiba warranty support. We link the tool rather than showing a result here, because the answer depends on the individual drive and only Toshiba warranty support can give it.
