I've seen wildly varying estimates of the number of writes allowed. I suspect the number has increased enormously with newer flash drives. I just bought an 8GB flash drive from memoryC, and there wasn't any warning of the life-time. > But if you reallyl need it, you should be able to remount it as > read/write with "mount -o remount,rw /" Actually, I'm quite puzzled by this. I did give this command. Before I gave it, "mount" showed /dev/sdb1 as ro, while after it was rw. However, the changes I made (such as adding a user) disappeared on re-booting (after running "sync"). If anyone can throw light on this I should be grateful.
