DNS323 finally died

[Scott O'Brien]

My DNS323 finally died. The power supply stopped working and took out something on the main board I think. I got another power supply off ebay but none of the drives are now recognised.

I still have a DNS327 running stock firmware at the moment and may swap that to Alt-F soon, but I am now awaiting a new Synology DS220j to arrive ... wonder if I will get 13 years out of that ...... I suspect not, but DLink no longer sell NAS systems in Australia so I didn't have much of a choice..

Anyway, Alt-F has been fantastic for me for 10 years, so thanks very much to Joao and the rest of the community. Great work.

And I now have a spare working power supply if anyone in Australia wants one.

I (in Melbourne) have a DNS-320L I bought about 3 years ago. Still working great. It couldn't hurt to have a spare PSU but I dunno if the PSUs are the same as the 323.

I've had several Buffalo NASes that worked great after unlocking them and installing Optware. They all died due to PSU failure. Nobody sells the PSUs anymore.

Yes, they are different.

Most likely electrolytic capacitors fault. They are the most failure-prone electronic components. 

Nobody sells the PSUs anymore.

If the box powers up and works fine otherwise, but the drives don't spin-up (you don't ear them or feel them "vibrate" ), then it might be the 12 Volt supply. If you have a voltmeter, you can check that at the power brick socket, diagram enclosed.

Hi guys,

Sorry Jezzaaaa, but they are different.

@Joao, thanks for the suggestion. The original power supply has no output at all and the power supply LED doesn't even come on. The new power supply seems to work fine - I measured 5 V and 12 V as expected.

I am constantly getting these errors in the system log (or ata1 depending on what drive bay is populated):

Apr 24 10:34:58 DNS-323 user.info kernel: ata2: hard resetting link

The drives were spinning up - I could hear them chirping at one stage. Based on a previous message in this group, the diagnosis was simply a dead DNS.

Yes, if the disks spin-up and yet can't communicate with the sata controller, that's a dead box.
