A Seagate engineer clarified the cause of the problems in the 7200.11 series.
The representative of Seagate explained the situation from the point of view of a person not working in Public Relations. The problem of slow media performance of 1.5 TB was most likely caused by the introduction of a chipset with a poor SATA implementation. When it became known that the problem was in the firmware, the corrected firmware versions were sent to the buyers who contacted the technical support for the correct version. This is a standard procedure for Seagate, which does not allow the firmware in wide circles to download.
The problem with the 7200.11 series, mentioned in the news last month, really made it work. A Seagate spokesperson reports that this is an old problem that is difficult to fix. When certain events occur, a log or log is written to the software. If the number of entries exceeds 320 and the media is disconnected from the power supply, initialization problems will occur, without BIOS reports. Engineers are working on software updates to avoid such errors.

Usually, the user must contact technical support for such an update and “this software must pass 5 different checks in order to make sure that it fits the special conditions before sending it to the user. In five cases, you can get: "Your media requires a different (or does not require) software update". " In any case, management submitted to the public the software in order to suppress the possible liability of carrier errors. "Suddenly, there was only one check, and that was applied only if the wrong software was sent."
Thus, some carriers, in particular with a capacity of 500GB, did not work with the SD1A firmware released earlier this week, and the update was removed from the site. Unlike the original issue with the journal, this “bricking” does not protect the media from sending a report to the BIOS, so it can be overwritten at any time.
