Provjerio sam 3 kom 16TB Exosa x18 (ST16000NM000J)

Na netu je većina tumačenja ove gornje poruke da se radi o diskovima iz velikih narudžbi raznih integratora koje su kasnije preprodane, puštene u maloprodajne kanale iako to teoretski nisu smjeli napraviti.

Karikirat ću sad malo, ali naruči se recimo 10 ovih punih do čepa
Sirko SSG-540p
Ipak smanji se u zadnji čas projekt na recimo 40 komada po šasiji i ostal si sa 200 diskova koje nekam moraš utopiti i samo ih pustiš van kroz nekog distributera s kojim inače surađuješ :)

I to je ok, sve dok su stvarno novi i nekorišteni, dapače, dobra prilika da i mi mali korisnici dođemo do dobrih diskova.
Problem su ove krivotvorine, rabljeni koji su prodaju kao novi jer očito postoji način i da netko drugi osim Seagatea resetira SMART. Na koncu, nisu ni rabljeni kuga koju treba pošto poto izbjegavati, uz 100% ispravnost i dobru cijenu, zašto ne.

I auto od 200.000km može biti 100% ispravan i imati dobru cijenu.

Samo… koliko dugo će biti ispravan?

Ako je u pitanju dizelaš koji je doživio tokarenje, zamjenu vodilica i reparaturu turbo puhala, bude išao taj možda i do 500-600k.

Lijevo, Toshiba P300 (još dok su 3TB modeli bili CMR), desno novi IronWolf 4TB koji je počeo umirati prvi dan (ponašao se puno gore nego ovih 10-tak realociranih sektora na slici).
Toshiba umirovljena prije godinu i nešto nakon 24/7 radnog staža u DIY serveriću i sad se povremeno koristi za offline backup.
Nisam tokario plattere a ni podmazivao aktuator :)

Evo na brzinu sam bacio račun...ako uzmemo u obzir da je prosječna veličina diska za CHIA mining bila 10TB, smanjenje netspacea u odnosu na vrhunac otpustilo je
oko 2 milijuna diskova nazad na tržište...to je jako puno diskova i nije čudno da se neko polakomio za parsto milijuna dolara zarade

Nakon povrata Exos-a kupio Ironwolf Pro. Pod napomenu sam stavio da zelim disk iz 2024., pa sam takav i dobio (10/24, prema provjeri novi je sa 0 sati rada a naljepnica je standardna kao sto ima original).

Ovaj radi, nadam se da nece zezati...
Kada se pokrene nije toliko glasan ali je nervozan, na dodir se osjeti koliko jako prenosi vibracije dalje. Ako je NAS na podu, tisi je u odnosu na druge povrsine. U radu rostilja kao Archive (5900okr) i Barracuda (5400okr). Definitivno po mojim mjerilima nije za dnevni boravak :)

Seagate hard drive controversy persists as scammers discover methods to alter reliability metrics:kafa:

Citiraj:

In a follow-up to the ongoing Seagate hard disk drive fiasco, German outlet Heise.de has uncovered a new method fraudsters use to sell used Seagate hard drives as new by manipulating their Field Accessible Reliability Metrics (FARM) values. This makes it increasingly difficult for consumers to detect tampered devices. Traditionally, buyers could identify used hard drives by comparing the operating hours reported in the SMART (Self-Monitoring, Analysis, and Reporting Technology) data with those in the FARM logs. However, fraudsters have altered the FARM logs' operating hours, making this comparison unreliable. This advancement in deceptive practices presents a significant challenge for consumers trying to verify the authenticity of their purchases.

Consumers must now seek alternative ways to confirm whether a hard drive is new. Comparing the SMART operating hours with the FARM Power-On Hours (POH) is insufficient. Instead, checking the operating hours of individual heads can help determine if a drive has been previously used. Another recommended method is examining the production date—new hard drives typically reach customers within six months of manufacturing. A significant delay between the production and purchase date could indicate potential fraud.

Additionally, the absence of a front-facing sticker displaying the serial number and barcode can serve as a red flag. Consumers can also use smartphone barcode scanners to verify the authenticity of a drive’s serial number. This issue first surfaced in January when reports emerged that used Seagate Exos enterprise-grade hard disk drives (HDDs) were being sold as new. Investigations revealed that the fraudsters had erased usage logs, altered serial numbers, and modified labels to make the drives appear unused. However, tools like smartmontools could still detect extensive usage histories, with some drives running over 22,000 hours.

Further investigations traced the origin of these fraudulent drives to Chinese cryptocurrency mining farms, particularly those mining Chia.:hitthewal:

During Chia’s peak, HDD demand surged, causing shortages and price hikes. As the profitability of Chia mining declined, many farms shut down, flooding the market with second-hand drives. These drives, often with 15,000 to 50,000 hours of prior use, had their internal records altered to appear new. Seagate denied involvement, launched an investigation, and provided tools to help consumers verify the authenticity of their purchases. Seagate has advised resellers to buy drives only from certified distribution partners to ensure authenticity. However, reports indicate that even some certified partners have inadvertently sold these fraudulent drives, highlighting supply chain vulnerabilities. The company emphasized that factory-recertified drives are clearly labeled and urged consumers to report any suspected fraudulent products directly to Seagate.
