Everything on the hardware side seems fine. But I am running Windows 2000 SP3 and we are doing some performance fixes, one of them is to enable Write Cache by right clicking the drives etc. But this fails to work. <BR />I'm just confirming this for myself that this is because the Write cache is controlled at the hardware level and therefore Win2k write cache will not work?<BR />Also I have the power protect option switched on via Win2k, is this a good thing?<BR /><BR />Thanks<BR />Kristian Tue, 13 Apr 2004 05:51:42 GMT https://community.hpe.com/t5/disk-enclosures/write-back-cache-on-sa-5i/m-p/3246284#M11778 Kristian Vidal 2004-04-13T05:51:42Z https://community.hpe.com/t5/disk-enclosures/write-back-cache-on-sa-5i/m-p/3246285#M11779 Hi,<BR />write cache i hardware controlled and you can enable or disable it from the RAID CARD controller ..<BR />You will have a option at the boot up to go into the RAID card setup.You can try out some things from there..<BR /><BR />Regards Tue, 13 Apr 2004 07:29:32 GMT https://community.hpe.com/t5/disk-enclosures/write-back-cache-on-sa-5i/m-p/3246285#M11779 Shaikh Imran 2004-04-13T07:29:32Z
