SONY PSX DESR-5100 queries

I know that will happen because I was experimenting with it's Magicgate support. But please feel free to prove me wrong because knowing that the PSX doesn't have a restriction on the allowable retail PlayStation 2 MG filekeys that is as tight as I think it is, will definitely be a blessing.

I don't have another ST3160022ACE unit. The firmware of most modern disks are stored on the platters of the disk itself too, so swapping the PCB is most likely not going to do anything.

Not to mention that since the calibration of the disk's mechanisms is stored on the controller's EEPROM, so swapping the PCB might make the receipient drive defunct.

I don't know whether the DVR functions of the PSX will remain intact if a Sony 40GB disk is used, since I couldn't resize the "lba28" region when I connected my faulty SCPH-20401 Maxtor disk to it. Without the dvr_hdd0: device, it probably can't record programmes.

I hope that someone else, regardless of who it is, can help to attach the DVRP's firmware.

 

Did anyone try the beta Linux disc on a DESR unit?
Just curious...

 

I got a semi-working DESR-7100 coming my way soon. I'll be able to test that and a lot of other things as soon I get it's DVD drive fixed.

 

Swapping PCBs between HDDs of the same model and variant is a common last-ditch method to revive a broken HDD with a suspected faulty logic board. (Last ditch, because it can be quite tough to track down a sufficiently similar drive, especially for an older model)

So if you have, for instance, two ST3160022ACE drives with reasonably close manufacture dates, the logic boards should be interchangeable.

For cost and engineering reasons, it would be highly unlikely that Sony's protection stuff would be in the service area of the HDD platters.

There are loads of that model out there, so maybe just snap up a cheap one and see what happens?

Edit: Of course, if they put something in the regular data area of the old HDD that's needed, and you can't get at it, then you might be stuffed...

 

Actually no, in this case, the Firmware is customized (has SONY code added to it) which implements additional commands used for PS2 specific DRM functions AKA: DNAS).

So the customized firmware is on the platters in the form of modified firmware modules.


edit: PSX harddrives DO HAVE customized firmware despites what the sticker says. It has been tested and confirmed...

 

Extra commands... sure they're not in the EEPROM?

If they really are on the platters... wow... sneaky! Not surprising though I guess, Sony are bastards like that.

 

A few years ago I was able to take a generic MAXTOR ROMULUS drive (4D040H2) transplant the firmware modules with SONY code (from a SONY 4D040H2) to it using PC3000 and now it detects as a SONY harddrive.

 

Ahoy!

So, the x360 scene is able to modify the hdd firmware modules.
What do you think? Could this possible with $ony drives, too?


Rgds.

 

No, XBOX360 people don't hack modules, they just change the manufacturer, model and serial number strings. Nothing more, nothing less.

 

Thought i read something about modules...
Okay, but they are able to modify the firmware.
Don't you think this could also possible for ps2?


Rgds.

 

I have 2 DESR-7700 units comming this way if you need any help whatsoever.

 

same as PS3 , auto exit to XMB

 

And if you use the swap magic dvd first?

 

And how to use Swap Magic on the DESR? Change discs on the parsed PSX? Regards
