PS2 PS2 SATA Adapter Not Working

[free1616]

Hello PSX-Place community,

I'm reaching out once again to seek your advice and expertise regarding an ongoing issue I've encountered with SATA adapters and my PS2 consoles.

To provide some context, I initially purchased a BitFunx GameStar SATA adapter from AliExpress to mod my PlayStation 2 SCPH-50004 console. It worked flawlessly, allowing me to expand the console's capabilities with a modded HDD setup.
Recently, I acquired a PS2 SCPH-39004 console with the intention of modding it as well. However, when I tried to use the same GameStar adapter with this console, it failed to communicate properly.
Thinking that the adapter might be faulty, I ordered a Kaico Edition SATA adapter for testing purposes. Unfortunately, this adapter also failed to be recognized by the SCPH-39004 console.

Interestingly, both adapters work perfectly fine when tested with my SCPH-50004 console. I've also attempted to connect the modded HDD from the SCPH-50004 to the SCPH-39004, but to no avail.
Even more perplexing is that the HDD doesn't seem to even power up when the PS2 SCPH-39004 is turned on.

I'm puzzled by this situation, especially considering that I have experience with modding and have successfully used SATA adapters in the past. If anyone has encountered similar compatibility issues or has any insights into potential solutions, I would greatly appreciate your assistance.
Thank you in advance for your help and support.
Best regards

HDDs:
Seagate ST500LM021
Toshiba MQ01ABD050

You might want to check the fuses on your 39004, specifically the PS9 and PS10 which responsible for powering up the HDD unit.
Both of the fuses might blown which causes your problem.

You have to open up your console to do that and the tools and have some knowledge about console repairing.

I've decided to explore alternative solutions to maintain the console's original state for the time being.
I've chosen to give the MX4SIO adapter a chance as a potential alternative. I'm curious to see if the MX4SIO adapter will provide a viable solution to the HDD connectivity issue.

Regarding your suggestion to check the fuses PS9 and PS10, I'll definitely look into that.

I've now connected the Kaico SATA adapter to my main console, the SCPH-50004.
I've noticed that, for example, there are no more audio distortions during FIFA gameplay, unlike with the Gamestar adapter, which exhibited distortions.

Thanks again for your help!
