Announcement
Recently we have received many feedbacks from our customers who were experiencing some troubles while running Seagate (ST31500341AS with SD15, 17 or 18) 1.5TB hard drive(s) on the QNAP NAS, such as randomly pause or hang for around 30 seconds at a time during certain write operations. And this randomly freezing will also lead to losing the existing RAID configuration.
Here is the statement from Seagate on TechReport.com which were posted on Nov. 10, 2008 (http://techreport.com/discussions.x/15863). Seagate has stated that they have noticed this and are working on an upgradeable firmware to resolve it.
In order to solve this problem for all the QNAP users before we can actually have the solution from Seagate, QNAP now provides our customers a special edition firmware, which is based on the latest official release (v2.0.3 build 1111) with Seagate ST31500341AS (SD15, 17 and 18) 1.5TB hard drive write-cache disabled. This should be able to fix the problem, but you might also experience some performance drop at the same time.
Enhancements
- Support Seagate 1.5TB HDD (ST31500341AS) - Disable write-cache on HDD model ST31500341AS with firmware SD15, SD17 or SD18.
