GNU ddrescue 1.30 significantly improves automatic data recovery from drives with dead heads, reducing the number of read errors needed for successful recovery by orders of magnitude, making it accessible for less experienced users. The update also introduces a new '--no-sweep' option and other enhancements.
The iOS 17.5 photo bug caused deleted photos to resurface on iPhones due to a new local storage scanning mechanism, not involving any Apple or iCloud servers. The issue was fixed in iOS 17.5.1 by removing this scanning feature, and affected users need to manually delete the restored photos from the Recents folder. Claims about photos reappearing on wiped and resold devices were debunked.
Voyager 1, the 46-year-old spacecraft, had been sending gibberish data since November, but a "poke" from NASA engineers on March 3 may have brought it back to life. Despite their age, Voyager 1 and Voyager 2 continue to provide valuable information about the cosmos, and NASA is determined to keep them operational for as long as possible. The recent glitch in Voyager 1's data is being analyzed, and engineers are working on a potential solution. Even if communication with Earth is lost, the probes will continue their interstellar journey, carrying golden records with information about humanity.
German data recovery specialist CBL Data Recovery confirms that USB memory sticks are becoming less reliable due to inferior memory chips and the move to storing multiple bits per flash cell. The company suspects that flash chips from manufacturers such as SK hynix, Sandisk, or Samsung that fail quality control checks are being resold into the market with lower memory capacities. The adoption of multi-level cell architectures exacerbates the situation, leading to decreased endurance and storage capacity. Users are advised to use high-quality storage hardware, keep it cool, access it annually, and leave unallocated space to maintain reliability.
Japan's Smart Lander for Investigating the Moon successfully landed on the lunar surface but encountered trouble with its solar panels, leading to a shutdown with 12 percent battery capacity remaining. Japan's Space Exploration Agency (JAXA) has recovered technical and image data from the lander and is hopeful that the downloaded data will provide insights into the mission's success. Despite the unexpected solar panel positioning, JAXA plans to provide an update on the lander's status at the end of the week and remains optimistic about the mission's achievements.
Google is investigating reports from Google Drive for desktop app users who claim that their personal files have disappeared from the cloud service. The issue seems to be a sync problem affecting a limited subset of users using Google Drive desktop versions 84.0.0.0 through 84.0.4.0. Google's support team has been assisting affected users with data recovery attempts, but so far, no solution has been found. Users are advised not to disconnect their accounts or delete/move the app data folder, and it is recommended to create a backup copy of the app folder as a precaution.
Scientists at the University of Sydney have successfully recovered gigabytes of data from a NASA mission to map dark matter around galaxy clusters using a new recovery system. The Super Pressure Balloon Imaging Telescope (SuperBIT) was launched from New Zealand and damaged upon landing in Argentina. However, two Data Recovery System packages containing the mission's information were safely retrieved. The study provides instructions to build the recovery system and highlights its importance in salvaging data in worst-case scenarios. The success of the system has led NASA to consider producing similar packages for future science missions.
Scientists at the University of Sydney have developed a Data Recovery System that successfully retrieved gigabytes of data from a NASA mission to map dark matter around galaxy clusters. The system was used after communication failed and the balloon-based telescope was damaged during landing. The recovery packages, containing over 200 gigabytes of information, including a map of dark matter and space photos, descended by parachute and landed safely. The study provides instructions to build the Data Recovery System and highlights its importance in salvaging data in worst-case scenarios. The success of the system has led NASA to consider producing these packages for other science missions.
A NASA telescope called SuperBIT, which launched on a balloon earlier this year, lost communication and suffered damage upon landing in Argentina. However, the 200 gigabytes of data it had collected, including stunning images of galaxy clusters, were safely copied to SD drives and parachuted to the ground. The telescope's main goal was to map dark matter around galaxy clusters by measuring how celestial objects warp space and time. The successful recovery of the data demonstrates that valuable science data can be salvaged even in worst-case scenarios.
SanDisk portable SSDs have been plagued by reliability issues, including data loss and failure, due to construction weaknesses such as improper solder material and oversized components. Data recovery specialist Attingo has observed these hardware problems and believes a recall is necessary as they cannot be resolved with a firmware update. SanDisk has not publicly responded to inquiries regarding compensation for lost data.
Google is addressing the storage access issue on some Pixel devices after updating to Android 14. The issue affects Pixel 6 and later models with multiple users, causing media storage inaccessibility or device reboots. Google has released a Google Play system update to prevent the issue and is working on a system update to restore access to media files without a factory reset. They are also investigating data recovery options for devices stuck in a boot loop. Users are advised to avoid creating or logging into secondary users until the OTA update is available.
A family accidentally deleted their entire photo album when a teenage daughter deleted photos from her iPad, which were also deleted from the family's iCloud account. The family was able to recover some of the lost pictures by reaching out to Apple Support, but a delay would have resulted in permanent loss. Deleting photos on Apple devices moves them to a Recently Deleted album, where they can be recovered within 30 days. It is important to regularly back up photos and check iCloud settings before deleting any photos. Family photo sharing can be convenient but carries the risk of accidentally deleting photos from multiple devices.
NTDEV has released live11, the first bootable Windows 11 live DVD designed to run entirely on RAM and fit on a 4GB virtual hard drive. It can be used for troubleshooting, data recovery, virus removal, or other tasks. However, it requires 8GB of RAM to boot and only works on systems with MBR and BIOS. NTDEV plans to address these issues and deliver other improvements in future updates.
An analysis of 2,007 damaged or defective hard disk drives (HDDs) by data recovery firm Secure Data Recovery has found that the average time before failure among the sample size was 2 years and 10 months, missing the three-year mark. The company also suggested that older drives were more durable and resilient than new drives, with most of the least durable and resilient hard drives from each manufacturer made after 2015. Secure Data Recovery blamed SMR and size for the dip in HDD reliability, with SMR impacting HDD reliability as the disks place components under "more stress."
