What markings are on the chip on the adapters ? The unbranded ones can be anything from one batch to the next varying from good to garbage.

The branded ones (assuming no fraudulent remarking) typically have a chip from either Marvell, JMicron or Sunplus.

The Marvell ones are generaly the most compatible (though there have been reports of newer revsions having issues).
The JMicron ones usually work well on many controllers, expect VIA 686B and ICH4 ones at least, where they might work OK ONLY if (U)DMA is disabled.
The Sunplus ones are those I know the least about. Startech uses them on their converters, which suggests they might be decent.

Of these, the Marvell and JMicron based ones usually support TRIM passthrough (for SSDs), FWIW.

@darry, thanks for the details about these SATA adaptors and the chips they use!

I have only one IDE to SATA adapter, so my experience with these is limited.
It is a StarTech with a Marvell chip and works great in my Ali Aladdin V SS7 box.

I have now tested this adapter on my i430TX system and it works perfectly here as well. For this test I used Hitachi 80GB and 120GB SATA laptop drives, and a 250GB Samsung SATA Harddisk.

@d00mo reported via PM that the AX5T patch J.3 BIOS I send him works perfectly with a Maxtor 120GB PATA HDD, but the 3 SATA drives are still not recognized by his PATA to SATA adapter.
I don’t believe that all 3 his SATA drives are faulty, so this no-brand SATA adapter must faulty or incompatible with his AOpen AX5T i430TX board.

TY for the update and TY again for the information, BIOS patches and test utilities that you have created and shared.

My Startech IDE2SAT2 ‎PATA2SATA3 uses a Sunplus SPIF223A chip. https://www.amazon.ca/dp/B00310MFPY
EDIT: I also have a Startech IDE2SAT2 thad has a Marvell chip https://www.amazon.ca/dp/B00EOJNGC2
AFAIK, there are (were?) other Startech models that use Marvell chips (like the one you have) and also some JMicron based ones.
