ReadyNAS 626x Internal SATA port is no longer working
Hi,
After a good long run, I think my 626X finally giving way. Last year, I had to change the RAM, and this week one of the SATA slots (Internal 1) stopped working.
I was routinely getting "volume downgraded" errors, and thought the disk was dying on me. Replacing the disk (twice) did not fix the issue (even with reboots), and then seeing the disk work in external USB enclosure, it dawned on me: it was the SATA port that had the problem.
Verified this by placing the disk on another slot (Internal 5), and it is now rescyning (will take 30+ hours...)
Now, what are my options?
Is it possible to fix it by just shaking of dust / blowing air (like old Nintendo cartridge days)
Shall I try to get a replacement I/O board (I would expect that to be extremely expensive).
Or it is time to move on? (As our debian version is no longer supported, and the service is on its last legs)
Any suggestions?
You could of course just keep it running with 5 disks.

There is a small chance the issue is with the power supply and the voltage in slot 1 is especially low due to some routing losses. Do you have time to test the unit with just one drive in slot 1? To do that, remove all drives (best to label where they came from so they can go back to the same slot after the experiment) and insert just one (not from the original array or containing any data you care about) and, if necessary, do a factory default. If it runs fine in that configuration, with the other drives not "pulling down" the voltage, then the power supply is a definite suspect.
Interesting.
Power supply might make sense.
If that turns out to be the case, how do I replace mine? Is it a standard form factor?

Of course. However, I can't be sure this will not spread to other slots. Over time I could have a 4 drive and 3 drive enclosure and so on.
(Btw, using eSATA I was able to add more ports, but they are really slow compared to native ones, so that is not a good solution either).
The power supply is a standard Flex ATX form factor with a modified pin-out. The 20-pin ATX connector is modified in the same was as other ReadyNAS. But you also need the 4-pin 12V CPU connection, and I don't know of any pre-modified supply that has that.
If you purchase one with a 20+4 connector, you can remove the two 12V wires to the +4 section and insert them in place of the -5V and -12V ones on the 20-pin section. Or, you can buy a 20+4 extender and make the mod there. If removing the pins is difficult for you, cutting and soldering the wires will also work (properly insulating the splices, of course).
