hot-swapping ide-cf-cardreader

Hi there,

I've got an ide-compactflash-cardreader which operates on the second ide-channel as master (no other devices are on the second ide-channel). My BIOS detects the CF-card as a hdd and also linux treats the CF-card as "normal" hdd (/dev/hdc). A "real" hdd and a dvd-rom are working on the first ide-channel.

This is working fine, but has one big problem: I've to shut down my linux-box to replace the CF-Card and boot again. That's getting boring. So I trie to swap the CF card while linux is running. But that causes some errors.

But let us start from scratch:
I unmount /dev/hdc and unregister the second ide-channel with hdparm -U. Then I replace the CF-card an try to reinitialize the ide-channel with hdparm -R. But this does not work properly.

So I 've tried to use the shellscripts which are offers with hdparm in the contrib-dir. But they also won't work:

make sure that you have unmounted the card before unplugging, and after changing card, try running the following two commands incase they help:

Hi dsd,

thanks for your answer.
I've tried these commands above, but they only works sometimes with some cf-cards. With others cards, my console get freezed while exceuting the touch command.

How does linux recognize the cf-card at startup (boot)? Is it possible to do this actions manually after linux was booting?

Thanks a lot...
