in sata_sil.c there is:
sil_blacklist [] = {
{ "ST320012AS", SIL_QUIRK_MOD15WRITE },
{ "ST330013AS", SIL_QUIRK_MOD15WRITE },
{ "ST340017AS", SIL_QUIRK_MOD15WRITE },
{ "ST360015AS", SIL_QUIRK_MOD15WRITE },
{ "ST380023AS", SIL_QUIRK_MOD15WRITE },
{ "ST3120023AS", SIL_QUIRK_MOD15WRITE },
{ "ST3160023AS", SIL_QUIRK_MOD15WRITE },
{ "ST3120026AS", SIL_QUIRK_MOD15WRITE },
{ "ST340014ASL", SIL_QUIRK_MOD15WRITE },
{ "ST360014ASL", SIL_QUIRK_MOD15WRITE },
{ "ST380011ASL", SIL_QUIRK_MOD15WRITE },
{ "ST3120022ASL", SIL_QUIRK_MOD15WRITE },
{ "ST3160021ASL", SIL_QUIRK_MOD15WRITE },
{ "Maxtor 4D060H3", SIL_QUIRK_UDMA5MAX },
{ }
};
I've got ST3120026AS and I've been using it with SIL3112 without this hack for
a long time - without any negative effects. The same impression on
ST3200822AS - is there any way to check if it is REALLY necessary? 15MB/s is
not what I'd expect on SATA...

It's necessary until we can prove otherwise. Simply running well
without your drive in the blacklist means nothing -- you just haven't
hit the error condition yet.

So how can I proove it? Are there any tests? It's been running for over a
year, almost 24/7 and nothing...

Still no response - so again:
is there ANY way to test if this hack is necessary for specific model of a
disk?

You need a bus analyzer, and need to test different sizes of FIS's. If
all possible sizes (2048 combinations) work on your device, the
blacklist entry is not needed.

is there any software bus analyzer? And if so, is there
Testing-different-sizes-of-FIS's-for-dummies anywhere ?

You could modify a few drivers to receive an "unknown FIS", or receive
all FIS's into a DMA-able area that the system could then read. So it's
doable. I just don't have time to teach all of SATA and ATA to you :)
