I'm trying to copy the whole contents of a CF memory card. I did a
And it works ok. Now I can change the card and write it:
cat file >/dev/sdb
I run sync in order to make sure buffers are flushed. However, I'm not sure I'm running the right command... man page says "sync flushes filesystem buffers" but I' not accessing the filesystem...
Question is: is it ok to run sync? or is there another program that I should use?
