41674 2002-04-04 00:31:00 Hi Everyone,

Could anyone please explain what a write behind caching for all drives is? and is it safe to disable it. I have a ME, 1200Mhz,496memory.

Thanks and Cheers.

Turning off WBC may make your programs more sluggish at times (e.g. when saving large amounts of data). There is a potential upside to turning off WBC - if you have a computer failure, there is more chance that you data is on the disk!

41676 2002-04-04 04:38:00 Write behind caching for all drives tells the computer to cache all of the disk writing operations to that particular drive. Basically, this means that a certain amount of what is being written to the disk is actually being stored in the RAM and isn't written to the disk until either the cache starts overflowing (in which case it starts writing from the bottom of the cache) or the computer is shut down. While enabling this setting increases performance significantly, it is important to mention that if your computer isn't shut down properly, there is a chance that the information isn't properly written to the disk, in which case it will be lost. This really isn't a big deal on your average desktop, but if you are running an important server and you don't have a UPS, it might be a problem. Guest (0)
