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.
Archivists are racing against time to preserve valuable government data vanishing from data.gov. A recent study revealed thousands of datasets have disappeared, with many agencies failing to properly maintain or update their entries. Independent archivists are now working to identify and archive these datasets before they're lost forever, utilizing tools like the Wayback Machine and creating independent repositories. This loss of data hinders transparency, research, and public accountability, emphasizing the critical need for better data management practices by government agencies.
HN commenters express concern about the disappearing datasets from data.gov, echoing the article's worries about government transparency and data preservation. Several highlight the importance of this data for research, accountability, and historical record. Some discuss the technical challenges involved in archiving this data, including dealing with varying formats, metadata issues, and the sheer volume of information. Others suggest potential solutions, such as decentralized archiving efforts and stronger legal mandates for data preservation. A few cynical comments point to potential intentional data deletion to obscure unfavorable information, while others lament the lack of consistent funding and resources allocated to these efforts. The recurring theme is the critical need for proactive measures to safeguard valuable public data from being lost.
The blog post details how the author lost access to a BitLocker-encrypted drive due to a Secure Boot policy change, even with the correct password. The TPM chip, responsible for storing the BitLocker recovery key, perceived the modified Secure Boot state as a potential security breach and refused to release the key. This highlighted a vulnerability in relying solely on the TPM for BitLocker recovery, especially when dual-booting or making system configuration changes. The author emphasizes the importance of backing up recovery keys outside the TPM, as recovery through Microsoft's account proved difficult and unhelpful in this specific scenario. Ultimately, the data remained inaccessible despite possessing the password and knowing the modifications made to the system.
HN commenters generally concur with the article's premise that relying solely on BitLocker without additional security measures like a TPM or Secure Boot can be risky. Several point out how easy it is to modify boot order or boot from external media to bypass BitLocker, effectively rendering it useless against a physically present attacker. Some commenters discuss alternative full-disk encryption solutions like Veracrypt, emphasizing its open-source nature and stronger security features. The discussion also touches upon the importance of pre-boot authentication, the limitations of relying solely on software-based security, and the practical considerations for different threat models. A few commenters share personal anecdotes of BitLocker failures or vulnerabilities they've encountered, further reinforcing the author's points. Overall, the prevailing sentiment suggests a healthy skepticism towards BitLocker's security when used without supporting hardware protections.
This spreadsheet documents a personal file system designed to mitigate data loss at home. It outlines a tiered backup strategy using various methods and media, including cloud storage (Google Drive, Backblaze), local network drives (NAS), and external hard drives. The system emphasizes redundancy by storing multiple copies of important data in different locations, and incorporates a structured approach to file organization and a regular backup schedule. The author categorizes their data by importance and sensitivity, employing different strategies for each category, reflecting a focus on preserving critical data in the event of various failure scenarios, from accidental deletion to hardware malfunction or even house fire.
Several commenters on Hacker News expressed skepticism about the practicality and necessity of the "Home Loss File System" presented in the linked Google Doc. Some questioned the complexity introduced by the system, suggesting simpler solutions like cloud backups or RAID would be more effective and less prone to user error. Others pointed out potential vulnerabilities related to security and data integrity, especially concerning the proposed encryption method and the reliance on physical media exchange. A few commenters questioned the overall value proposition, arguing that the risk of complete home loss, while real, might be better mitigated through insurance rather than a complex custom file system. The discussion also touched on potential improvements to the system, such as using existing decentralized storage solutions and more robust encryption algorithms.
