Tall ships (porthole)

Usually, when a disk or memory card has bad sectors attempting to read those sectors returns an error. Y'know, so that whatever was trying to read it actually knows that that particular bit of data can't be read and so can do something sensible.

Unless it's a crappy microSD card, in which case attempting to read a bad sector will cause the card to stop responding. Actually that's not quite what happens - it does return an error, but then doesn't respond to any further reads. Okay, that's mildly annoying but I can deal with it.

Unless it's a really crappy microSD card, in which case most of the time it won't bother with any kind of error but will just return garbage. And not consistent garbage, but different garbage whenever you try to read that sector.

Unless it's a really really crappy microSD card, in which case it's not just one bad sector, but about 100MB that's now effectively gone. Except because the card doesn't bother with actual errors, you don't know which 100MB is gone.

ViewRanger support are made of win and awesome.

One of the casualties of that crappy microSD card was all the mapping data for ViewRanger. While it does let you re-download maps for free, I couldn't find a way to get a list of which maps/tiles I'd paid for.

So I sent them an email earlier today and about 40 minutes later I got a reply. On a Sunday! It gets better - the reply contained a link to a zip that I could just unpack and copy across to the phone.

Now I just need to recover the other applications that had some data stored on the card, and any data that survived. The casualties include any photos I'd taken on the phone this year, which fortunately isn't many as I have an actual camera I normally use (but unfortunately does include a set of photos I'd been meaning to post for a recent walk, as I didn't have my camera that time).
