Flash drives have a limited write capacity (most things do but these are especially prone when you line it all up).
More recent/high grade stuff is OK and it is somewhat of an artifact like pulling a drive out while writing/pulling a USB stick without stopping it first: modern stuff tends not to go for the catastrophic meltdown route (although it is still not advised) but try to keep stuff like virtual memory (unless you stick it on a normal drive), logfiles (unless they are held in memory/buffer in which case you can probably do it) and other repeated disc write activity to a minimum. They also tend to come with an onboard controller to mark off bad sectors and replace with some of the spare ones available negating it yet further.
As for OK I know quite a few people to do it as a (more) secure OS (stuff like at in internet cafe/using someone elses machine) or as a repair kit although it tends to be run from a CD/DVD and have a USB stick for everything else or have the USB stick be the drive that the CD/DVD decompresses too (main kernel is on the disc but less used apps on the drive).
) Can someone explain why it's ok to install GNU(Linux if it is) and why XP can't (Waits for FAST
) Thanks in advance
