All,

Problem Summary:
I have a SanDisk ImageMate USB compactFlash + SecureDigital + MultiMediaCard 
reader, and I am getting IO errors trying to read a 128MB SimpleTech CF card 
with 2.4 kernels.

Details:

I have an 8MB Canon CF card and a 128MB SimpleTech CF card.

With the USB reader, I see:
OS or Device      | 8MB | 128MB |
------------------+-----+-------+
MacOS 9           |  OK |   OK  |
RH 2.4.17-0.16smp |  OK |  ERR  |
RH 2.4.18-3       |  OK |  ERR  |

ERR means that I get IO errors when I try to 'cp -a' the contents of the CF 
card to local disk.
"pc: reading '/mnt/flash1.....': Input/output error" is repeated for many of 
the files on the card, but not all of them.  Most of them seem to be later 
files.

Also, with a PCMCIA adapter in the RH 2.4.18-3, both CF cards work.
Both cards also work in a HandEra 300 PDA and a Canon PowerShot A40 digital 
camera.

Any suggestions of how I could track down the problem?  (I've submitted a bug 
report to SanDisk as well, but this looks like a Linux problem to me.)
