It's probably PTP if a good card doesn't show up using fdisk -l.

Chances are, you're going to need to use a regular USB attached card reader instead.

The trick is that you're going to need it...

Don't click on the in the file manager (as that mounts it, and you don't really want that when trying to recover images). Also, if you swap cards without using the "eject" feature, the FAT can be...

Then, after you get a good copy, you can use other utilities to find and correct file system problems (chkdsk...

If you can get it where it's showing up, you can make as many passes as you need to, provided you're using a log file. That way, you can let it cool off in between passes, and it will only try to...

Right (to both).

Try it using a different reader. Your new HP will probably boot with with Mepis (try it and see). Also, try it using your camera has a reader. See what you get doing it with...

Hmmm. It looks like you have a 512MB card from what I can see of previous posts.

So, it should support it. But, have you got another reader you can try? I see lots of problems reported with...

That particular Alcor Reader (showing up as ID 058f:9360) does *not* support SDHC cards.

BTW, I'm curious where you got that "/dev/partition_of_SDcard" parameter you were trying to use that was giving you those errors. Did you see something like that using fdisk -l? Sometimes, you...

That you were getting errors probably means it saw something. But, it may not necessarily show up as sdb. Sometimes, you'll see other drive designations assigned.

See if you can get to a PC with...

I even use ddrescue for backups now, making a full disk image copies of my drives (using a yyyymmdd date format to name the backup images). That way, in the event of a drive failure, I can restore...

P.S.

I first became aware of it when I slipped and fell on a PC while it was in the middle of defragging a drive under Windows. That was a *huge* mistake (knocking the PC over while it was...

That's where a program like ddrescue comes in. You can start those...
