SSD Unitiserve Problems

Posted by: Red MacGregor on 20 February 2014

I recently obtained a very nice 6 month old U/S off Ebay.  For the first couple of days was very impressed with the sound quality when played into my NDac,555,  52 & 250. However, in the last couple of days the U/S has stuttered  (like a stuck record) on 3 occasions causing the U/S to reboot. Additionally from the system records it also appears to be rebooting while not in use. Is this par for the course or do I have a problem that has already been identified and can be resolved?

 

Any assistance would be appreciated. Thanks Steve.

Could be one of two things -

1. Hard drive bad or going bad (why did the previous owner sell, one might ask).

2. Under-voltage power supply. I had the same frequent re-booting behavior. Measured the voltage, it was only 10.2 VDC. Bought a new 4A 12 VDC power supply, measures12.6 VDC. Problem solved, no more re-booting.

It can't be 1, as the US is the SSD version. It may be 2 though. Could your dealer let you try a different power supply. Or just buy a linear one, which will made the sound a lot better too.

I've had three SSDs go bad. They do go bad Halibut so I hope any you have in use are backed up.

I've had quite a few SSD's go bad in PC's.  3 in a period of 6 months, all OK since (touch wood!)

 

In each case they have failed catastrophically, i.e. they are not recognised at all, completely unreadable, whereas a conventional hard drive can stutter as it retries to read bad parts of the disk.

Well thanks for the suggestions of what the possible problem might be. I'll speak to Naim as the U/S is so new perhaps they will send a replacement PSU via a dealer.

Just one further question - does the U/S ever power down? If it doesn't I take it the up time is the last time it rebooted?

Thanks - Steve

Bad SSD firmware or incorrect OS system paging settings are the two worst offenders - fortunately, use of the UnitiServe SSD effectively guarantees that your data storage is independent of the server itself.  (If you encode to FLAC, you're virtually assured that you can use your library with nearly anything else.)
