The Solution for Seagate 7200.11 HDDs


Recommended Posts

There is no new firmware that is to be loaded to "fix" an issue, that is something one can do once (and only once) the drive has been revived to not hit the same issue again.

The original issue (either the LBA0 or the BSY one) can happen because the firmware hangs/enters a no-exit loop when the event log hits 320 or a multiple of (320 + x*256),

The procedure(s) reset this in such a way that - typically - the disk is fully functional for 3-6 months of use or more.

Hence in 

 there is the point "IMPORTANT" that says:

In case of success, DON'T EVEN THINK to consider the unbricked hard disk as "FULLY WORKING" and avoid backing up the DATA (the drive has failed, and like all HD's will fail - again - sooner or later).

.....

DO NOT be obsessed by "firmware updating", the condition that can cause the problem is an extremely rare event and statistically will happen again, without any firmware update, no sooner than three to six months of intensive use, you have ALL the time in the world to perform the firmware update after the unbricking, and even if it bricks again, you now have the tools and knowledge needed to unbrick it in a few minutes.

Upgrading the firmware is a risky operation, DO NOT DO IT unless really necessary, and ONLY do it AFTER you have your DATA back and backed up on another media.

If the above wasn't explicit enough, DON'T EVEN THINK of attempting a firmware upgrade on a drive that shows 0LBA or BSY symptoms, in the best case, it will do NOTHING, in the worst case it may put the drive in an "undefined" state from which it may be EXTREMELY difficult to get it in a "fixable" state again.

Just DON'T do it!

.....

If the drive doesn't work after the procedure(s) have been applied (or if it works intermittently as in your case) it simply means that it suffers from another problem that needs to be diagnosed, which requires specific knowledge (besides possibly specific tools ).

There is somewhere on the thread a somewhat detailed list of commands that are available via serial, but most probably you need omething *like* SEDIV:

and some training in using it.

If you don't care about data on the drives, it is simply not worth the time/money/hassle.
