Wish it were so. You can read online how some people formatted their USB flash stick using the Ext3 filesystem, and the flash stick failed very soon afterward due to the journal for the filesystem overwriting the same section of the flash memory too many times. I had a customer that used Ext3 on a CF card used for an embedded computer against my recommendation, and the CF card failed within a few months of very light use. Probably for the same reason. Flash memory has improved as to how many writes it can tolerate, but it's hard to know when you buy one whether you get a version that can tolerate a higher number of overwrites. > I have a couple of laptops with SSD's in them and beat them up pretty > good. > So far so good. For USB flash and CF cards I recommend using the ext2 filesystem because it's unjournaled. I've yet to have a CF card using ext2 fail, and I've run some of them for 5 to 7 years. LogFS is also a new filesystem that seems to be meant for USB and CF cards, but it's not considered stable yet. I haven't tested it yet, but I'm looking forward to trying it out when it's a little more mature so that other machines can read it. -- Chris -- Chris Knadle [email protected] _______________________________________________ Mid-Hudson Valley Linux Users Group http://mhvlug.org http://mhvlug.org/cgi-bin/mailman/listinfo/mhvlug Upcoming Meetings (6pm - 8pm) MHVLS Auditorium Oct 6 - Creating Browser Extensions for Firefox and Chrome Nov 3 - Open Source Hardware: Bugs, Beagles and Beyond Dec 1 - IBM's Open Client Deployment
