Evidence and limits

COMDEX Fall 1997 report on IBM Deskstar 18GP · COMDEX Fall 1997 Deskstar 18GP passage

Contemporary report identifies the 16.8 GB desktop HDD, GMR heads, RPM/seek/interface context, and OEM-only target.

No retail availability or shared performance workload is established; systems using the drive were described as months away.

What difference it made

Comparable benchmark evidence has not been established for this record. Missing results do not imply poor performance.

Release evidence

The year above is a research-cohort label. Announcement, production, shipment and retail availability are distinct events.

Proposed event: product announcement and oem exhibition
Proposed timing: 1997-11 · month precision
Assessment: review required

The contemporary COMDEX report supports an OEM-only family announcement/exhibition, not an actual 1997 shipment or retail/system launch.

PC Watch / Impress · COMDEX Fall '97 report, 1997-11-17 to 21; IBM Deskstar 18GP passage
Contemporary report identifies the 16.8GB Deskstar 18GP desktop 3.5-inch HDD, says IBM announced it just before COMDEX, and explicitly says it was OEM-only with no retail sale and systems at least three to four months away.

Open questions and review

Exact announcement date; OEM order/ship date; first PC-system availability; geography; whether announcement alone qualifies.

No owner discrepancy decision is recorded. This does not mean there are no unresolved issues.

evidence gap · follow up

COMDEX announcement/exhibition was followed by systems expected at least three to four months later; no 1997 shipment is shown.

Audit source · COMDEX Fall 1997 report

Report identifies OEM-only status and delayed system availability.

Follow-up: Keep announcement separate from shipment and system availability.

Original intake sources

These notes preserve the state at intake. Later verification is shown under Release evidence above; an original note saying verification had not occurred is not the current assessment.

Original research note

Family identity. Contemporary reporting supports a November introduction/display but warns that PC availability was later; first commercial/OEM shipment remains unresolved.
