      Summary: There has been a report of reemergence of SanDisk SSD’s 40,000-hours death bug. This article will discuss the nature of this issue and provide precautions and solutions to counter it.

      You might recollect that in March 2020, a severe SanDisk SSD’s 40,000-hours death bug threatened the data integrity of SanDisk SSD users. The issue was reported first by the users with servers based on the SanDisk SSDs. Many RAID array users too joined the league of victims soon.

      One of the popular sites, Hacker News, reported it again when the site went down on Friday, July 8, 2023. The site owners tackled the situation by shifting to another server and confirmed the same via the discussions on their page.


      What is the SanDisk SSD 40,000 Death Bug?

      The SSD 40000 hours death bug is a manufacturer firmware defect in SanDisk SAS SSDs. Dell and HPE identified the issue for the first time in 2020 and warned their users against the threat.

      The official statement in 2020 by Western Digital, the manufacturer and owner of SanDisk, acknowledged the firmware issue in SAS SSD. But, they didn’t share any concrete detail and directed the whole thing toward the responsible OEM.

      The SanDisk SSD’s Death Bug renders the SSDs with 200 GB to 1.6 TB capacity unusable after 40,000 hours of usage, which is approximately 4 years and 206 days. So, it might not be an imminent danger to users who have recently started using the drives for their servers or RAID arrays. However, if not dealt with on time, the bug results in complete SSD failure, with all the data lost beyond the scope of recovery.

      Dell and HP Enterprise released a firmware update in 2020, but it’s not clear whether this update tackles the latest reappearance of SanDisk SSD’s 40,000-hours Death Bug.

      What can you do?

      The most recent victim Hacker News reported “HN is down again with what appears to be a second disk failure. This is on the fallback server, which we switched to last night when the primary server failed.” and they had to switch to their rarely used backups to bring the site online.


      Apparently, you can do nothing more than rely on the backups you’ve created for failsafe operations of your server. However, if you’ve been taking those backups on the same SSDs, it is better to immediately start creating a backup of those too on a different SSD or other storage media.

      None of the stakeholders has issued an official statement, fixes, or updates, but it’s better to be on the safer side than to lose valuable data. If your SSD is still in a working condition, you may try to update it using the 2020 Dell updates or HPE updates, depending on your SSD provider, to resolve this death bug.

      We suggest you run the Stellar Drive Monitor on your SSD, and if you haven’t yet taken a backup of your data, it’s high time you do it. The drive monitor can help you get real-time information on your SSD’s health, temperature, and performance. Moreover, you can also scan your drive for bad sectors and clone the drive if need be. The drive monitor alerts you with warnings if it senses any issue with your SSD.
