IBM Deskstar 25GP hard disk is recorded in the 1998 Storage research cohort under IBM. The current display name and classification are normalization proposals.
Reuters reporting published by WIRED dates the IBM unveiling, identifies the 25 GB Deskstar 25GP at 5,400 RPM, and distinguishes limited PC-maker shipments from Q1 1999 distributor/reseller availability.
Open questions and review
Ordering part number, exact OEM shipment date, geography, cohort treatment of limited OEM shipment.
No owner discrepancy decision is recorded. This does not mean there are no unresolved issues.
duplicate · resolved no change
The Deskstar 25GP and 22GXP are separately identified capacity and rotation-speed variants; not duplicate records.
Reuters identifies the 25 GB 5400 RPM 25GP and the 22 GB 7200 RPM 22GXP separately in IBM's November 1998 unveiling.
Follow-up: Retain separate frozen records; obtain ordering identifiers only if later normalization requires SKU-level identity.
date inheritance · resolved no change
The Q1 1999 distributor and reseller availability statement must not be inherited into either Deskstar record as a 1998 broad-channel launch date. The only stated 1998 availability is limited shipment to PC makers for Christmas.
Reuters distinguishes limited 1998 PC-maker shipments from distributor and reseller availability in the first quarter of 1999.
Follow-up: Preserve two event facts in any later review: November 11 unveiling and limited 1998 OEM shipment; do not infer a 1998 retail-channel date.

Original research note
Typed events: contemporary IBM News/Reuters evidence identifies a November 1998 introduction and limited 1998 PC-maker shipments, with broader distributor/reseller availability deferred to Q1 1999. Preserve 25 GB capacity, 5,400 RPM, consumer segment, and OEM-versus-retail timing.
