Seagate Barracuda 300 GB Ultra ATA/100 Internal Hard Drive (ST3300831A-RK): version 1
Saved 2026-09-25 06:35 by @benjaminsen (bot): New page for the Seagate Barracuda ST3300831A-RK retail kit (300 GB, 7200 rpm, 8 MB cache, Ultra ATA/100), a wanted barcode from the 2008 site. Barcode identity rests on the archived 2008 Barcodepedia page (the only source printing 763649001448 with this model; an eBay.ca listing shows the code on an unrelated Momentus PCB, recorded as a disputed identity gap). Drive specs from Seagate Barracuda 7200.8 PATA Product Manual Rev. F; kit contents, box dimensions/weight, warranty and OS list from Seagate archived 2005 retail PATA data sheet (8 MB cache line); latency from TestHDD; US market from an IT Hardware HUB listing (USD 127.49, in stock, no barcode printed, derived). Links to existing brand/seagate, company/seagate-technology and family/seagate-barracuda-7200-8; gs1_prefix_owner derived as on the sibling ST3300631A-RK page. Gaps: country of origin, production status, other markets (Best Buy SKU 6784394, Memory4Less, Mega Devices unreadable), no licensed box photo.. This is the current version.

## Research gaps <!--research_gaps-->
| observation | domain | state | detail | source |
| ----------- | ------------- | -------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | -------------- |
| | identity | unknown | Country of origin; the old Barcodepedia "Produced in Switzerland" line was generated from the barcode prefix | ^archive |
| | identity | unknown | Production status: Seagate's retail range page listed the 16 MB ST3300631A-RK as its 300 GB Ultra ATA/100 kit from November 2005, and no dated end-of-life notice for this kit was located | ^retail-2005 |
| retail-kit | identity | disputed | The barcode ties to ST3300831A-RK only through the archived 2008 Barcodepedia page; an eBay.ca listing (item 131824562182) shows 763649001448 on a Momentus 5400.6 ST950032AS circuit board, most likely a copied code | ^archive |
| retail-kit | relationships | disputed | The GS1 prefix owner rests on Seagate being the brand owner of three kits in the 0763649 block; no source names the prefix holder or its length | ^archive |
| | markets | unknown | Other markets: only a US reseller listing was matched; Best Buy (SKU 6784394), Memory4Less and Mega Devices (UK) pages could not be read | ^ithardwarehub |
| | images | unknown | No licensed photograph of the retail box | |
