<font size="4">DroidX suddenly lost access to SD card. Rebooted after reseating card and phone says SD card is blank. I attempted to access the card via a USB SD card reader on my Ubuntu 10.04 system. The kernel tells me a bunch of SCSI messages I've put below. However, my question is when trying to use dd or ddrescue to access the device I get these messages:<br>
<br>dd_rescue: (fatal): open "/dev/sdc" failed: No medium found<br><br>dd: opening `/dev/sdc': No medium found<br><br>So here are the kernel messages when the SD card is sensed:<br>May 20 12:07:58 arwen kernel: [172595.490118] usb 1-4.3: new high speed USB device using ehci_hcd and address 5<br>

I just want to recover an image of whatever data is on the flash card. It is a 16GB card with some photos, applications, and videos. I had downloaded most of the photos but don't have the last month or so. Recorded some video from two different concerts I went to that I wanted to save. A bit frustrated that dd won't access the card. Google search isn't giving me much info on how to know when a card is truly inaccessible.<br clear="all">
