I have one of those tiny 256 MB devices that plug into a USB port. I use it to move data between home and work, amongst other things. So for me, it usually doesn't make sense to mount it read only. What I do, however, is to use the noatime option. That way, I can at least read files with reckless abandon without causing any extraneous writes, I hope. I worry about "using up" the superblocks and possibly the location of the root directory, however. Would using softupdates be likely to decrease the amount of writing to those areas, and so perhaps increase the lifetime of the device? Any other tricks? Here is one: I have a (little used, but still handy) 32 MB MSDOS file system in the first slice. I'm planning to repartition the device once in a while, each time changing the size of the initial slice in order to move the most used areas in the FreeBSD slice around. - Harald To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message
