compact flash problem

Hi folks.

I'm running kubuntu 7.10 on an HP a6010n (I think that's the model number). It has a built-in compact flash reader.

Using a 1 GB CF card, I'm able to write the partition table, create an ext2 filesystem, and mount the partition.

However, when I try to write to the filesystem, I see a slew of messages in syslog:

Nov 19 20:33:06 HP kernel: [13142.607646] sd 2:0:0:0: [sdb] Sense Key : No Sense [current]
Nov 19 20:33:06 HP kernel: [13142.607657] sd 2:0:0:0: [sdb] Add. Sense: No additional sense information

Then when I umount and re-mount the filesystem, none of the files I thought I had created are there.

Any ideas? Thanks!

Thumbs up


1)First check your CF card is detected or not.Like you i am also using Disk onchip in my system.Using "fdisk -l" you can do it.The CF card will be detected as Secondary Hard Disk (/dev/hdb).
2) Try this Command for partitioning:
fdisk /dev/hdb

You will be getting like this:

The number of cylinders for this disk is set to 9729.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
a) software that runs at boot time (e.g., old versions of LILO)
b) booting and partitioning software from other OSs

Command (m for help):

Enter there p, to check the partition table.
3> after that u can do the partitioning.

Just to let folks know - the CF card had gone bad. I tried using it on another machine, and that failed also.

Major bummer, since it was brand new.
