Alas, I spoke to soon. The brand new mSATA SSD device has now fried also in my dev machine, which has clearly some unusual internal damage that coincided immediately on my trying out that el-cheapo BlueTooth audio receiver (only plugged into the laptop for usb power - nothing supposed to be to do with the laptop otherwise...).
My dev laptop continues to operate via simple SD card boot, but I do wonder if some voltage regulator is not doing its job internally in the laptop now, and that the surviving-thus-far SD card is struggling silently prior to also kicking the bucket.
An expensive time. I was already feeling a bit down because of cherry-picking of dev WeeDogLinux code/idea/algorithm without acknowledgement, and other Puppy dev's clear lack of any spirit of distro collaboration (rather the opposite to say the least). Then there was that Pup-biased forum 'moderator' who saw fit to move my HowTo thread to almost invisible WeeDog subforum space after my moving it out of a complaining Puppy-dev's boot-related thread into a separate thread of my own under House Training->HowTo. I guess I am guilty of not 'sooking-in' like some of the other Dog-named distro devs.
What an un-sharing lot some, at least, of these Puppy distro devs are; soul destroying in their insecurity really (well I suspect they have a lot to be insecure about). Of course existing House-Training->HowTo thread in no way indicated 'un-collaborative Puppy-only area' and with admin rights I could have unilaterally changed Beginners and Users sub-sections to be more forum-distro-agnostic (and either, removed, or moved that 'moderator' to at most allowing his moderation of 'Mainline Puppy distros subsection'), and thus more encouraging of collaboration and sharing. However, I consider my rockedge-given admin rights a privilege rather than a right to step on the toes of any others (including Puppy moderators, who clearly imagine more toe-stepping powers of their un-cooperative own).
Anyway, if you are reading this description of 'disaster' you have left the secure Puppy environment and are in WeeDogLinux segregated compound.
I have given up pushing for collaboration in such a forum, preferring now to leave the insecure Puppy-dev lot (and a few of their minions) to their distro-competition worries/attitude. I have no doubt personally, however, that collaboration and sharing is the key in any recipe for a better community (and probably much better distros too) - that that attitude lacks in some major quarters here makes this 'forum' a smaller and less significant place.
Main thing for me now is that I have to dig out some other potential machines for my home-grown WDL ongoing, no longer so open and public, development efforts, so good time for overall short to medium length development computing break, I suppose.
