So, just a light post, I upgraded my Pi4 last night and found the Linux firmware breaks a 32bit install.
I’ve been meaning to change to 64bit for months, but as it’s my DMZ box for torrents, radicale, etc, then it’s just finding the right time to convert an adhoc setup into my ansible scripts.
Luckily I had a SD backup from September to get it running again
So, what have you broken over the holidays?
I’ve had some luck with portable drives by removing the drive from enclosure and attaching it directly to sata-bus instead of USB. Also, as a general rule for anyone who might stumble on this, whenever attempting recovery at first create an image (I use ddrescue) and work with that. That way you’ll minimize risk of causing even more damage.
A while ago we “fixed” couple of hard drives with my brother. All of them had a single faulty diode, apparently it was a known failure point on those drives and brother found instructions online how to bypass that diode. Obviously that doesn’t really fix the drives, but a small piece of wire and some soldering was enough to get drives spinning again long enough that he could copy data over to new drives.
