Default How to tell if CF card is faulty?

It may be that it's the filesystem on the card and not the card itself. The
original FAT system was restricted to about 32MB.

Try to use both the faulty 128MB card and the good 32MB card in a reader
and use linux's fdisk to look at the partitions. eg:

fdisk /dev/sda
...
... (use 'p' to print partition table)

Device Boot Start End Blocks Id System
/dev/sda1 1 38144 39059440 83 Linux
/dev/sda2 38145 38154 10240 4 FAT16 32M

The 'System' column at the far right should how the flash-card
is formatted.


Can you format the card under linux and use it normally for some
reasonable length of time?

There are various MSDOS and linux utilities to do a 'surface-check'
of hard drives which should also be usable on a flash-card.
