[Voyage-linux] MPD corrupting files?

[Bill Shurvinton]

HDD is powered by its own psu in an icybox enclosure.

Nothing in dmesg or /var/log/syslog other than the usb DAC keeps resetting.

For some reason, despite having run smartctl a few weeks ago when i 
first fitted the drive it now has decided that is not supported on the 
disk. I'm not sure what has happened there as I have swapped between 2 
models of the t5710 thin client so just maybe there is a USB firmware 
difference between them.

ideally I would try another hardware platform to check compatibility, 
but the neo e90 I was originally going to use steadfastly refuses to 
boot voyage. I am getting convinced there is some sort of hardware 
compatibility here, just not sure what.
