raw file access for a usb attached digital memory card

My Compact Flash Didgital Memory card appears to have bit the
dust. There are some pics on it ( vacation ) that I'd really
like to get off of it.

I've tried to
dd if=/dev/sda of=outfile bs=2048k
and I get some data... but it's not what I'm hoping / expecting
to get. My log shows:

sd 5:0:0:0: SCSI error: return code = 0x08000002
sda: Current: sense key: Medium Error
Additional sense: Unrecovered read error
Info fld=0xf0f58bf
end_request: I/O error, dev sda, sector 1005968

Buffer I/O error on device sda1, logical block 1005920

.... is there different / better way than dd to get the raw
data off of the card? I figure that if I have the raw data,
I might be able to re-assemble some of the .jpg files that
used to be on it.....

I've tried some 'win32' programs.. but the memory card is
just not being recognized as a valid drive...

Any info / suggestions would be appreciated.

add 'conv=noerror conv=sync' - noerror will keep going past read errors
and sync will fill in zeroes for missing data.
