Lost about 700 photos, the result of a full day of shooting in 3 locations. So far tried TestDisk/PhotoRec with no success, since they can't see there is a card. The camera offers to format the card, but I don't dare to do that (and try a recover after) with no backup first. I am quite upset about this, since a lot of people are waiting for the photos, only for a few there is a partial replacement (well... at least it was not a commercial endeavour)


  1. The log shows you're using a USB card reader. Try a laptop which with an embedded one (i.e. not a MacBook Pro: they also use a USB reader), for example a Dell Latitude. You might be able to access the card as a raw block device then.


  2. it cannot be read with either my photo camera (Canon), mu video camera (Kodak), the internal reader in EeePC and the desktop with this reader.

    can't extract data with dd either "dd: opening `/dev/sdb': No such device or address"

  3. I'm not sure how you can post insults to Fedora Planet one day and then ask Fedora Planet for help the next day...

  4. @Anonymous: i don't know where to start replying to this...
    - believe or not, i have quite a few friends in the community that share my points of view;
    - i don't post stuff on Fedora Planet, i write on my blog, which is aggregated to Fedora Planet, but not only;
    - the ***** in RHDT don't do kernel development or disk tools;
    - insults?

  5. Hi Nicu,
    You can use http://pc-inspector-file-recovery.uptodown.com/ on windows.

  6. First of all try to make a image of the sd with dd then work with the image not with the sd.

  7. i can't access the device, /dev/sdb is not readable even for dd. and if i would be able to access the file system, then photorec would probably restore everything, i used it a few times before.

  8. Just a stab in the dark here, but any friends who are kernel hackers and can disable the error checking portion of the kernel's mount to /dev?

  9. Sorry pal, you are in big trouble (according dmesg)... But there are hope: a few months ago I could not access a moldy cdrom using dd (the device were not accessible), but dvdisaster could. Maybe a programmer can explain the difference between dd and dvdisaster read methods and point a solution for your case...

    BTW, I am your fan. I begin use fedora because your comics and the use of device mapper snapshots in the fedora livecd. In other words, to normal peoples I begin use fedora because your comics 8-D.

    Sorry by the poor engligh use...

  10. The internal reader in the EeePC is also USB. Find someone around who has a non-USB internal reader, one with a dedicated controller. The one in Dell Latitudes is a Ricoh and dmesg messages talk about mmc0 when using it.


  11. @shpnft: thanks for the story :) back then i stopped the comics due to the lack of feedback, is nice to learn they were of use for someone

  12. Salut

    poate merge

  13. am zis deja ca am incercat PhotoRec si nu merge

  14. I have a Dell Latitude e6400 laptop with integrated card-reader as recommended above, and am technically qualified to dd (byte-wise copy) to another medium (DVD) and/or attempt non-destructive recovery after doing some reading up. But you'd need to Fed-Ex (or similar) the sdhc to me (in EU). If that would be of any help, drop an email to clefthook @ yahoo DOT com for mailing address + arrangements.

    Sincerely, etc.

  15. Hi, So...were you able to access your data? If so , how? I'm curious.


  16. no, but i was really busy the past few days, didn't had the time to focus on it

  17. As per my experience i know one company who is specialized in data recovery. Try, your luck

  18. I feel happiness to read the content that you are posting. Advice by Sivupeili
