Depending on on the size of files you write it'll affect performance since the CPU will have to wait for the HDD to complete the write before giving back control. This is almost thes same as the printer spooling. If you're not spooling everytime you send a print command to the printer control is taken by the printer until it gets done printing. Of course, it a little faster with the HDD. If the file being written is small enough to be written in the HDD cache, you might not notice a slow down but if you're talking about more than a couple of MB then you will have to wait until it's all written by the hdd before control is given back. The only beneift you'll get for disabling this option is that anything you've written to the hdd will always be there regardless if you shut down the system as soon as it's done or left it on. The reason being, you cannot shut down the system because the write process is not finish yet since you will not have control until it's done. On the otherhand with Write Cache Enable there's a good chance you can lose data because you will have control even some of the data being written is still in the ram.

Jiggz is one smart kid

To add to his post.. If you ever used SmartDrive (smartdrv) under Dos, you know that by disabling the write-cache your system becomes very slow. Windows' read- and write-caches seem pretty efficient, so disabling those will give you an even bigger slowdown.

With SmartDrive, it wouldn't even let you Ctrl+Alt+Del the PC if its cache wasn't written yet: it would just display a message "Flushing the cache...", and only after the flush would it restart the PC.

Don't forget that the drive cache is used even when working with the Swap file, so when you run out of physical memory everything will seem much slower for ya.

because i got a bad 75GXP and called IBM for a RMA

the tech support asked me to disable the cache writing of the drive by using feature tool after do an erase disk

Just turn it back on now that your hard drive is working again.. However, it sounds like you have a hard drive that is "on it's way out"..
