MSI B450-A PRO doesn't recognize external HDD via esata-sata
I've got a HDD fantec external enclosure with esata II port and its own power supply. I've bought an esata-sata cable to connect this enclosure to one of my mobo's 6 sata III ports.
Firstly I connected the fantec power supply, then its esata-sata cable and then I've started an ubuntu live session. After that I switched on the enclosure but nothing happened: the enclosure's led remained switched off and no external device icon appeared on ubuntu desktop. I switched off the enclosure, removed the esata-sata cable and connected the enclosure via an usb cable, then switched the enclosure on and it worked: its led switched on and the device icon appeared on the desktop. I supposed the brand new esata-sata cable failed but I checked it by a tester (@ ohm scale) and verified there was a link between some pins of the esata and sata plugs. So I supposed the enclosure's esata port didn't work properly and I tested it and verified there was a link between some esata's pins and the pins connected to the HDD. I'm not skilled but I guess both the cable and the enclosure work fine. That said, can you tell me why my mobo is not able to load an external device, like my enclosure, via its sata ports? Moreover I saw that nothing was listed in sata port list within bios environment when I started the bios with the enclosure connected via esata-sata cable. Should I modify something in bios to make it "see" a esata-sata cable as a common sata-sata inner cable? |

Two pins off to the side of the connector ("ears") are placed on motherboards that provide power. Then a cable with bus-power pins on it, would pass bus power to a drive. You would want to use a "plain" ESATA cable with no ears on it, if the enclosure has its own AC power. It's not clear whether sataio.org ever standardized this connector, and the options it has. There is even a motherboard connector, with ESATA and USB pins on the same connector, as a variant. The intention being, that a USB cable can go into that particular flavor of ESATA connector. Making it a "combo port", serving ESATA or USB function, depending on cable used. Paul |

MSI B450-A PRO doesn't recognize external HDD via esata-sata
I just purchased a "generic" female esata - female sata cable, I didn't know anything about "plain" or not cables, honestly I saw only "eared" esata plugs on the web until now. Can you please show me which esata form cable should I get? An amazon or aliexpress link would be ok so I won't be wrong.
Let me understand better why mine doesn't work, especially why the fantec box's led remains switched off. As far as you said my cable (with "ears") takes energy from the mobo so I guess the reason is there's "something" within the fantec that avoid it to get power from its power supply while connected via this "eared" cable, isn't it? Moreover I guess if I didn't connect its power supply it'd not work anyway because the energy taken from the "ears" would be not enough, right? Just a "punk" solution: can't I just isolate or cut/interrupt these 2 wires? I bought this cable only for this goal but it's useless as it is. Consider that I've already tried to connect it with both cables at the same time (usb 3 and esata-sata II). The fantec's led switched on and it was recognized connected via usb therefore it was as there were no sata cable. Can this be useful to get informations about how this "thing" works? Finally a last note about these attempts, maybe this'll be useful maybe not.. Every time after I use this new esata-sata cable and replace the hdd inside the PC case or I use the usb cable to connect the fantec box, after rebooting the PC the CPU mobo led switches on and the booting freezes. This doesn't happen if I use only the usb cable. When this happens maybe I can restart just pushing the PC case reset button maybe it doesn't work and I've to switch off the PC. This [switching on - cpu led - switching off] can go on for 2-3-4 times without a rule (I guess). Most of times I solve just switching off once and waiting 10 minutes, then the PC boots properly. Can this behavior be useful to understand better the relationship between my mobo and this esata cable? |

Can this behavior be useful to understand better the relationship between my mobo and this esata cable? I can't tell what's wrong from this distance. I'm only examining possibilities, and I don't like the fact that the ESATA people added those power contacts like they did. It didn't seem to be backed up with any standards body. I can't tell you what their intentions were on bus power. ESATA would be a lot easier to understand if the ESATA was just "data" and no "power", as a data cable doesn't have nearly as many failure modes. A drive which freezes, could be a drive with flaky power, a data cable with incorrect signal amplitude. I think ESATA could support 1 meter and 2 meter cables, but the 1 meter cables means it's more likely to work if the motherboard side isn't programmed properly. A drive can "freeze" if it goes crazy, and this can be a sign of a power problem. You might hear noises of "spin up" and "spin down" if there is a power problem, like the voltage to the drive isn't sufficient. But that's all that comes to mind. Paul |

Your enclosure expects to see the power / signal on the eSATA cable 'ears' and doesn't so doesn't turn on. When I used eSATA if the mobo didn't have eSATA ports then I used a PCI-e / eSATA expansion card (and an eSATA to eSATA cable). This provides the power on the 'ears' which tells the enclosure there's an eSATA cable plugged in and to run in eSATA mode. Without that signal the enclosure 'thinks' there's not a cable plugged in so doesn't turn on. -- Shaun.

Add some sensing in parallel with the diff receiver. Or, note a lack of delimiters in the decoded data stream, via the (unlocked) free running receive clock. But the logic table of the receiver can also be considered to offer information, and there have been some receiver chips (Motorola Autobahn) which could tell you something is disconnected. The receiver can even have a "bias" on the inputs that helps it detect the disconnect case. The capacitors that may be in the high speed diff path, have been removed for clarity. With capacitors in the path, that helps reduce the opportunity for a DC bias problem traveling from end to end (TX DC levels upset RX DC levels or bias). ******* The power detection (if there is to be an issue), is independent of link state. An enclosure with its own power supply, doesn't even need "ears" on its interface as it can completely ignore the ears if it wants (and likely, should). While you could likely do an either/or power implementation, you can't add too much drop to VBUS if doing some fancy selector circuit. I have not drawn the reverse direction of the cable. SATA has 7 pins GND TX+ TX- GND RX+ RX- GND and there are two pairs of wires involved. One goes east-west, the other goes west-east. The link "trains up" on a symbol stream, until both ends of the link operate at a common clock, and things like JK symbols (or equivalent) can be seen. As the rates on SATA/ESATA go up, the link encoding method may differ, but it's all a lot of low amplitude physical layers. USB3/PCIe/SATA all use ~1V level diff signalling. And they're also likely to use flyby terminators in the 100-110 ohm range, as that is typical for the cheap cabling or FR4 they're designed for. Paul |

Thanks for your explanations. Now I've no time to read Paul's last reply and I'll do it later because I want to learn something on that.
~misfit~ solved that with a PCIe so for now I just want to ask you if this https://www.amazon.it/gp/product/B007FVQIVW/ can be good for my scenario. Data transfer is only 3gbps, so it's esata II like my fantec enclosure, but it costs only 5 euros (a bit less than 5 usd) shipped. |

If I were you I'd be ordering that (and an eSATA to eSATA cable) and trying it. I don't know for sure but I think your enclosure uses the 'power in' on eSATA and USB to tell it what mode to run in. No power in signal on either means it won't power up. It's not a lot of money to spend to find out for sure. Please let us know how it goes. I always read all of Paul's posts as he is the most knowledgeable hardware guy I know of. Sometimes though the answer is simple and if you get too deep into the minutiae of the situation you can lose sight of that. Good luck! -- Shaun.

Sorry Paul for my misunderstanding but I'm newbie and my english is bad. As I said time before I had already tried to set all the 6 mobo's sata ports with "hot plug" enabled but I still had no success, I mean I had tried to connect the fantec to each one of the 6 ports. As I already said the fantec power supply works because the fantec is properly recognized if connected via usb cable.
Due to that I thought it was the fantec's esata port the faulty because my mobo would work properly, I mean sata ports can be set that way ("hot plug"), and you said esata a sata signals are the same. So if it's not the enclosure's esata port broken and the mobo works properly, what's the faulty, maybe this brand new esata-sata cable? Or maybe the fantec's power supply doesn't work and all the energy to boot and run an Ubuntu OS from the fantec was taken only from the usb3 port? Do you think it could be possible? |
