SD card I/O errors and corruption

Sat Jun 28 21:27:24 UTC 2008

Hi all,

I am having problems with two Kingston 2GB SD cards. 

My laptop (Asus Aspire 4520) has a built-in card reader:
$ lspci 
01:09.1 SD Host controller: Ricoh Co Ltd R5C822 SD/SDIO/MMC/MS/MSPro Host
Adapter (rev 22)
01:09.2 System peripheral: Ricoh Co Ltd R5C843 MMC Host Controller (rev 12)
01:09.3 System peripheral: Ricoh Co Ltd R5C592 Memory Stick Bus Host Adapter
(rev 12)
01:09.4 System peripheral: Ricoh Co Ltd xD-Picture Card Controller (rev ff)

Earlier today, I inserted an SD card containing a hundred photos or so.
F-spot tried to import them, but crashed and all my photos were lost. Here
is the error message displayed:

I am able to reproduce this crash. Something similar happens when I try to
copy the files from the SD card in Nautilus.

Looking in dmesg outout,each time this happens, there is upwards of 600
lines of error messages. Here is a sample:

First, I thought it was a damaged SD card, but I have a second identical one
and the same problems ocurr. Strangely enough, I have no problem with the 32
MB card supplied with the camera, a Canon.

Any ideas what is going on here? Is is possible that both (!) 2GB are
damaged? Would it be worth trying to reformat them? 

In the meantime, I will stick to transfering photos via the USB cable.

Thanks.
