Re: Corrupt data - RAID sata_sil 3114 chip

[Bernd Schubert <bs@q-leap.de>]

Hello Bengt,

sil3114 is known to cause data corruption with some disks. So far I only know
about Seagate, but maybe there issues with newer Samsungs as well?

http://lkml.indiana.edu/hypermail/linux/kernel/0710.2/2035.html

Unfortuntely this issue has been simply ignored by the SATA developers :(
So if you want to be on the safe side, go an get another controller. 

I hope I won't frighten you too much, but it also might be possible one of 
your disks has a problem,  I have also seen a few broken disks, which don't 
return what you write to it...


Cheers,
Bernd
