About 4 years ago I had a problem with my MD600 (running as core/store). One of the white warning lights on the front illuminated indicating a problem with a hard drive.
After much unsuccessful faffing with new drives I resigned myself to running on the old drives with the light on. It worked and /debug showed 6gig of storage (= 2x3gig drives) so the option of running at risk seemed, at the time, better than more mucking about. The system has since been up and running uninterrupted (no reboots or power cycles that I can recall) for four years. Software release is still 2.494 (build 429).
Today nothing would play from the store. The stats show the correct number of albums, "Show Album details" gives basic meta-data and track titles. But the album covers will not show and the albums will not load or play. So presumably one disk has failed and the other is broken from four years ago. Radio stations and TIDAL still work. I can "View Log", "View Status" and "View notifications" but not access the Directory Listing.
But what is weird is the information that is available. Would not track titles and performance statistics be stored on a disk? Why does some information appear and other not? TouchPC allows sorting by Import Date/Release Date/etc. These symptoms seem to suggest corrupted files rather than a failed disk.
Or could this issue be symptomatic of some kind of memory problem? The core has been running for >61 days - the longest I have ever seen.
No attempt has been made to recover from the problem yet. Are there any other tests or information which might inform next steps?
I have a full current back-up and spare drives so not panicking yet - just taking the opportunity to gain further insight into the data architecture.
