SATA corruption

[karanbhagoji]

Hello all,

We have custom boards with imx6 quad processor with android jelly bean running on 3.0.35 kernel with SATA boot , size 30 gb .  After using the board for some time we are getting a SATA corruption messages, the errors are different for different boards, like eg

1->

EXT4-fs error (device sda4): ext4_lookup:1044: inode #22: comm er.ServerThread: deleted inode referenced: 69

Aborting journal on device sda4-8.

4->

binder: 4716:4716 transaction failed 29189, size 80-4

binder: 4716:4716 transaction failed 29189, size 212-4

We getting stuck in this error. Due to these errors the displays hangs at splash screen with no android UI prompt .All the errors indicate that the SATA cards are getting corrupted. Is there any error with the JB android /  kernel/ anything  which is causing this corruption?

Kindly advice , also suggest solutions if any.

Regards,

Karan

Hello Ambika ,

Sorry for the late reply , but the above  suggestion is  true , it is due to improper power supply and etc. Abrupt power off after long time is the main reason as the journalling is not updated, and hence may lead to sata corruption, also to add , during power off if the journalling regions are corrupt then there is no way to update the same and hence error. Also recommend to check the connectors for loose connections .

Karan

Hi Karan

corruption may be caused by sudden turn of power supplies,

recommended to use linux poweroff command.

Best regards

Hello Igor,

Agreed that the sudden turn turn off of power supplies may be  an issue here, but its not always the case, the device boots

after an abrupt power supply failure I have already tried to turn off the power supply abruptly many times, but the SATA card is not getting corrupted..

Please suggest any way to overcome this corruption.

Regards,

Karan

Hi Karan,

I have the same problem of firmware getting corrupted with sata boot in imx6q board, whether have you got any clues??

Thanks & Regards,
