A plasticizer called B2E, used in dampeners within vintage hard drives, is degrading and turning into a gooey substance. This "goo" can contaminate the platters and heads of the drive, rendering it unusable. While impacting mostly older Seagate SCSI drives from the late 90s and early 2000s, other manufacturers like Maxtor and Quantum also used similar dampeners, though failure rates seem lower. The degradation appears unavoidable due to B2E's chemical instability, posing a preservation risk for data stored on these drives.
Backblaze's 12-year hard drive failure rate analysis, visualized through interactive charts, reveals interesting trends. While drive sizes have increased significantly, failure rates haven't followed a clear pattern related to size. Different manufacturers demonstrate varying reliability, with some models showing notably higher or lower failure rates than others. The data allows exploration of failure rates over time, by manufacturer, model, and size, providing valuable insights into drive longevity for large-scale deployments. The visualization highlights the complexity of predicting drive failure and the importance of ongoing monitoring.
Hacker News users discussed the methodology and presentation of the Backblaze data drive statistics. Several commenters questioned the lack of confidence intervals or error bars, making it difficult to draw meaningful conclusions about drive reliability, especially regarding less common models. Others pointed out the potential for selection bias due to Backblaze's specific usage patterns and purchasing decisions. Some suggested alternative visualizations, like Kaplan-Meier survival curves, would be more informative. A few commenters praised the long-term data collection and its value for the community, while also acknowledging its limitations. The visualization itself was generally well-received, with some suggestions for improvements like interactive filtering.
German consumers are reporting that Seagate hard drives advertised and sold as new were actually refurbished drives with heavy prior usage. Some drives reportedly logged tens of thousands of power-on hours and possessed SMART data indicating significant wear, including reallocated sectors and high spin-retry counts. This affects several models, including IronWolf and Exos enterprise-grade drives purchased through various retailers. While Seagate has initiated replacements for some affected customers, the extent of the issue and the company's official response remain unclear. Concerns persist regarding the potential for widespread resale of used drives as new, raising questions about Seagate's quality control and refurbishment practices.
Hacker News commenters express skepticism and concern over the report of Seagate allegedly selling used hard drives as new in Germany. Several users doubt the veracity of the claims, suggesting the reported drive hours could be a SMART reporting error or a misunderstanding. Others point out the potential for refurbished drives to be sold unknowingly, highlighting the difficulty in distinguishing between genuinely new and refurbished drives. Some commenters call for more evidence, suggesting analysis of the drive's physical condition or firmware versions. A few users share anecdotes of similar experiences with Seagate drives failing prematurely. The overall sentiment is one of caution towards Seagate, with some users recommending alternative brands.

Several Hacker News commenters corroborate the article's claims about degrading dampers in older hard drives, sharing personal experiences of encountering the issue and its resulting drive failures. Some discuss the chemical composition of the deteriorating material, suggesting it's likely a silicone-based polymer. Others offer potential solutions, like replacing the affected dampers, or using freezing temperatures to temporarily harden the material and allow data recovery. A few commenters note the planned obsolescence aspect, with manufacturers potentially using materials with known degradation timelines. There's also debate on the effectiveness of storing drives vertically versus horizontally, and the role of temperature and humidity in accelerating the decay. Finally, some users express frustration with the lack of readily available replacement dampers and the difficulty of the repair process.
The Hacker News post "Gooey rubber that's slowly ruining old hard drives" has generated a number of comments discussing the article's topic of degrading flexible circuits within older hard drives. Several commenters corroborate the author's experience, sharing their own encounters with sticky residue and failing drives.
One commenter mentions encountering the issue with old Seagate drives specifically, while another points out that Western Digital drives from the same era appear to be less susceptible. This leads to a brief discussion about potential manufacturing differences and the specific materials used by each company.
Another thread focuses on the chemical composition of the deteriorating material, with speculation about the plasticizers used and the potential for outgassing of volatile organic compounds (VOCs). One user, identifying as a chemist, suggests the material is likely a thermoplastic elastomer (TPE) and offers further insights into its potential degradation pathways. They also mention the possibility of cleaning the residue with isopropyl alcohol, although another commenter cautions against this due to the potential for damage to other components.
Several users express concern about the long-term archival implications of this issue, lamenting the potential loss of data stored on older drives. This prompts discussion about the importance of regular backups and the challenges of preserving digital information over extended periods.
A few comments delve into the potential causes of the degradation, with theories ranging from temperature fluctuations to the presence of ozone. One user suggests that the issue might be exacerbated by improper storage conditions, highlighting the importance of keeping drives in a cool, dry environment.
Finally, some commenters offer practical advice for dealing with affected drives, including suggestions for cleaning the sticky residue and recovering data. One commenter even links to a relevant data recovery forum, providing a resource for those experiencing this issue.
Overall, the comments on the Hacker News post provide valuable anecdotal evidence, technical insights, and practical advice related to the issue of degrading flexible circuits in older hard drives. They highlight the challenges of long-term data preservation and underscore the importance of understanding the potential failure modes of storage media.
