PSX DESR7700 general questions

Yea i wasnt optimistic with the other HDD tests i did today but I figured what the hell since all the parts were in front of me. :) mad about my HDD duplicator failing though. Just when I needed it....usually how this stuff happens anyways isn't it.

Yeah, now when the replacement duplicator arrives the HDD will fail...
 
I managed to fix the duplicator yesterday. I set the HDD on the machine to clone and left work. Its a slow machine but it is reliable. Transfers about 130-170MB per MINUTE. So....it takes a long time. Ill be back there on Monday and it should be finished. Then I can proceed with my test.
 
The transfer completed today. I swapped control boards on the drives.....PSX does not boot....from either HDD anymore. Im really mad at this result. Now I am not sure what happened here. It appears this PSX is now dead. Damn.
 
I haven't given up yet. The drive im speaking of was from the fully working 7700. I'm still quite bitter about this. I still have the 7700 that boots but crashes on ps2 games. Im wondering if I swap motherboards.....what have I got to lose at this point?

That's terrible to hear. Did you verify if the duplicator still detects the "dead" drive? Is it just the PSX that can't detect it or is the drive dead to everything?
 
Tomorrow I'll find out more. I left it at work last night and will be back tomorrow. Either drive does nothing. The PSX boots to the PSX screen, then goes black. It looks like some static or odd distortion flickers at top of screen every couple of seconds then stops after 20 seconds or so. Both, source and new drive do the same now. Very irritating.
 
Alright. So....i now have one 7700 that boots to xmb but crashes on PS2 DVD games and will not mount any CD, and the other 7700 that was fully working is now dead completely. The hard drive in the working one is trashed. The drive I bought and the original drive both behave the same way. Something happened...not sure what. The are unmountable and unrecognized even being plugged in. DISKPART in cmd prompt doesnt even see the either drive. My hard drive duplicator doesnt recognize them anymore either. These drives are effectively DEAD. Thus my formerly working 7700 is now permanently bricked.

I tried swapping the main ps2 board from the perfectly working psx to the other machine, but it would not boot to xmb with that setup......aarrgghhh. Well. Shit. :/ i cannot repair my semi working 7700 and i have a bricked 7700. I wonder if this $320 option this guy made can help me but i doubt it at this point.​
 
You cannot expect Windows to understand APA, he supports only MBR and GPT. Besides that, DESR's HDD are encrypted, so for anything which not decrypting it by providing key in specify way, treating is as empty because for them is filled by random data without any meaning.

If disk is detected on PC and can be fully read (which means reading all sectors) on PC, it means is fully working. But if You not see drives as devices, then it means they are dead because they are not communicating.

Cloning disk on ancient duplicators is pointless if they doing it only in PIO mode (just because of speed). You can use ANY software on any operating system which not modifying drive content and offer sector by sector copy (eg dd on Linux, IsoBuster/DMDE/HDD Raw Copy Tool on Windows).

But this junk is already hacked, just not yet published. So fingers crossed and be patient.

I've seen this stated elsewhere, I was wondering if there is an RSS feed, twitter/facebook/IG account, Discord or some other place which we can follow to keep up to date with the latest developments.

I know that a hardware mod has been done (320$ is a bit steep) but I guess that this is using a different approach by hacking the firmware on the internal NAND?
 
Data on NAND (xfrom0) can be used for booting something like FMCB (normally it is used for updates and bootstrap), but it will not defeat HDD security alone. What can deal with it is modification of DVRP firmware. Both solutions works and are still in development, yet none public.

BTW: AFAIK the IDE Emulator supports DESR models but user must provide HDD ID (can be read by dedicated application on PS2 side or on PC via sending special ata commands - of course only from original PS2/DESR HDDs).
 
Nice, I guess I'll just keep checking from time to time this forum to hopefully see some news about the development of the hack and be updated when it goes public.
 
Hello everyone, I'm new here but I wanted to know about replacing the disk. I have a Hitachi HDS722525VLAT80 drive in my DESR-7500. If you have two identical drives, has anyone tried to clone all the data from the original drive to a new, working drive and then replace the logic PCB?
