IIRC, it's actually missing entirely. It's just open pads but with R4 on the silkscreen. @Raidernick Do other adapters with the Marvell controller exhibit the same Samsung drive issue?

Is there a guide for doing this mod? I assume it is just a replacement of an existing resistor but where exactly is "R4"?

As long as it's the green adapter above with the master/slave jumpers then you can get UDMA6 to work as long as all the solder joints are good(you might need to reflow stuff). As for the Samsung drive issue, it's the whole issue I posted about a while back where if you combine a Samsung B drive with cerbios 2.3.1 or greater and a hdd over 1tb(I tested 2,3 and 4) that on first console boot the DVD drive will give a busy error in XBMC or just not read the disc at all until you reboot the console once. Rebooting the console, starting xblast(or similar) first THEN the bios or putting the disc in before bios load does not cause the issue. It only happens on first boot directly to bios THEN inserting the disc and you get a busy error or it just won't read. It's a very specific issue that only happens under a specific set of circumstances but is very annoying. Using the china adpater prevents the bug entirely so on those consoles that is what I use instead of startech which I use for every other drive type.

I also keep forgetting about the resistor mod. Maybe I'll buy a pile of AliExpress clones and put it there... If it fixes all these issues, why the HELL wouldn't they populate R4 themselves? Wouldn't it improve their sales? Will it really run with a UDMA-6 bios? I keep seeing that people can only get UDMA-5 and that's only with the DVD drive disconnected. I keep forgetting about the Samsung drives. VERY important point. What about the HDD over 1TB thing? I haven't seen that. And newer Cerbios versions? I'm not familiar with those issues. Maybe I should get one of these, populate R4 and do some conclusive testing for us all.

Gotcha. Well I guess I’ll be ordering new caps for the fella. lol hopefully that fixes my issues.

That green china adapter is fine as long as you put a 0603 100ohm resistor at R4. Doing that will give instant boot times and allow the adapter to run in UDMA6 mode at near UDMA6 speeds(around 90-95% speed). It's not as good as startech, but close enough at a small fraction of the price. Also, the startech chipset does have that incompatibility with newer cerbios versions, samsung b dvd drives and hdd's over 1tb in size(this may be hit or miss for some people).

Just finished designing my SATA adaptor prototype... The idea was to have a similar layout to the generic 3.5" adaptors, while using the Marvell IC found on StarTech adaptors. The majority of the SMD components are on the rear side of the PCB. Full size Molex connector with reversed orientation to better suit HDD caddy/power cable. Switch for master/slave/cable select, instead of just a pin header and jumper. PHD connector to use DVD cable as alternative power source (experimental) PHD connector also eliminates the DVDrom (no dvd-check bios required) Power and HDD activity LEDs... I'll still make some changes, but I'll get a couple prototypes made up as they are. So, I can test fitment and the performance of the device before I continue any further. Any feedback would be much appreciated, Nem

I didn't even know the forum was running in 2017.

Whenever you think caps need to be replaced, ALWAYS do a full recap of the device in question. As long as you're paying shipping, capacitors are cheap, and you don't want a mix of freshly replaced caps and caps that will need to soon be replaced all side by side with each other. Clean slate.

That is VERY cool. I'm glad to hear that you now have two working Xeniums.

I remember hearing word that an playable version of StarCraft Ghost had been salvaged from a dev box. Had an .iso ever been made available to the public? Would love to see what could have been.

FTP, SMB, or you can dock the drive to a PC if it is unlocked.

Do you have a part number of source you can share? Thanks

Worked like a charm!! Thank you. I sent recovery.bin via ftp to E:\ drive on Xbox. Ran recovery by way of switch on mod and fixed. Thanks much Gary

Gotcha. I guess my confusion comes from that my current issue started after I swapped the caps. I’ll definitely swap out the five silver 6.3v ones as you suggested. I was just verifying if using those 10v ones where I did would be an issue. Since you don’t seem to think that is an issue then I grow concerned as to what potential damage I did to the mobo when I swapped them lol. I hope I didn’t mess anything up but it seems possible to me at this point if the caps were fine there. Reason being as I said, it worked before I touched anything…

My first pc had dual 5 1/4” floppy drives and 4kb of ram with no hdd. Lol.

startech and similar brands, supports multiple ata interface speeds - you can use stock 40pin cable. chinese, limited ata interface support, so you need to use 80pin cable. some cheap adapters support 40pin cable, hit or miss. inferior build quality. personally i use chinese adapter, no problems. 2tb hdd no problems.

Boot lag and loading speed is the major setback with the cheap adapters. Yes, Amazon still has the Startech adapter for less than $20 shipped If you're in the US.

I don't see where anyone said they wouldn't work. As I mentioned earlier, it's perfectly fine to recap the entire board. I have several that have been fully recapped. In your case, you just replaced the wrong caps for your issue. Think of it like taking your car to the shop due to bad front brakes and they replace your rear brakes instead. Of course they're new brakes, but it's not doing anything to fix the front set. Hope that doesn't make things more confusing.

After researching that adapter, it seems that it is limited to certain UDMA speeds, and lags significantly at boot when using a DVD-ROM drive (unplugged DVD drive leads to instant boot times). The design may have been improved upon since the postings that I have found, but really: The Startech is 20 bucks. That's an hour of work in this drowning economy. A cheapo adapter is, on average, 7-10 dollars. I have always used Startechs and have blasted away at UDMA-6 with perfect reliability and snappy speeds with every one. The cheapos have issues and not great quality control. Several end up DOA. As long as it's one box, I don't see what the reason would be for not just getting one. You know it'll work and it'll perform. Whereas with a cheapo, you saved a whopping 12 dollars once and now may have to spend money again because it may not meet expectations. Now, if you were buying in bulk to mod consoles regularly, then yes, that would add up and you may wanna figure out a way to use them often without many problems. But for one personal build, I'd say Startech, and it's worth the extra money.

I use Startech whenever possible tbf. I have had mixed results with the China adapter 1 on that page. Some worked fine, others worked for a while then died, some were DOA. Build quality does vary a LOT on the cheaper Sata adpaters in my experience. I used to buy them in batches of 10 and ALWAYS had at least 3 in each batch that were DOA. A Startech is pretty much guaranteed to work without issues for a long time.

Yeah I looked up the red/orange and saw it was a ram issue. The odd thing was that it sometimes tosses green in there too. Like flickers between green and orange for a couple seconds. Then goes red/orange. Not all the time though. Also could you all explain to me why you think the 3300 10v caps wouldn’t work there. Looking at the old caps and according to the wiki interactive board that should be what goes there. Unfortunately I have to get new ones either way (beyond the leaking one that needs replaced) cause the legs are damaged and or/very short.

The problem with the generic adapters is the quality control isn't really there. Each one of the same model may work well or may not. And the generic adapters vary in compatibility in general. There are 2-3 different interface chips AFAIK. The XBox doesn't like all of them.
