I have tested one *major* brand of IDE flash devices and 2 brands of CF
devices, in more than 20K power fail tests.

Both suffer from low level failures, which cause the IDE driver layer to "give
up" with
"unrecoverable errors". The CF is so bad that I just gve up on the testing
after a few hundred cycles.

The IDE flash was better, but not much.

Will raiserfs be happy if the underlying IDE /dev/hdxx driver returns
"unrecoverable error" from the IDE device?

Your call.
