/var/log/messages while inserting the SD via a USB2.0 reader
This is very likely unrelated: I'm attempting to insert the SD card using a
USB 2.0 SD card reader. The attached file is the logged output during the
device insert (and removal: after the line with "REMOVED").
I do get a /dev/sdb device, but fdisk will not read it. I'm definitely NOT
getting the /dev/sdb1 partition which I can still get on the SD card slot on
the notebook after a eject and insert cycle.
I want to use this SD card reader so I can reformat the SD card.
For what it's worth. I have not yet rebooted since the BUG that started this
bug report.
This bug might have to do with using larger than 2GB SD card than with any general bug. I was able to upload the data without problems to a 2GB SD card using 2.6.20-1.2981.fc7. I have not retested the 4 GB card with this kernel. I think this is actually a hardware defect with a lot of cheaper card readers. I managed to duplicate this with a 4GB card, using a reader that exhibited similar problems that you describe. Why I think this is a hardware problem is that it corrupted the card on Windows too. There are two types of >2GB cards out there. - SDHC cards (which need an SDHC capable reader) - old format SD cards that break the spec and just happen to work on some readers, but not all. I don't think there's much we can do here. |
