vuli 0 Posted July 25, 2011 Report Share Posted July 25, 2011 Hi! I have 2x 1TB WD Caviar Black with 64MB Cache, but If I check in ATA option under one of this HDD for Cache it shows Unknown. I have also 2 other WD Caviar Blue with 16Mb cache, for this one it shows corectly. Quote Link to post Share on other sites
Fiery 474 Posted July 25, 2011 Report Share Posted July 25, 2011 Due to limitations of ATA spec, most drives with 64MB cache cannot report their cache size in the ATA autodetect block. So what you see there is normal, unfortunately. Quote Link to post Share on other sites
vuli 0 Posted July 25, 2011 Author Report Share Posted July 25, 2011 Aha, so it is the same if, disk is on IDE, AHCI or RAID bus. Thanks. Quote Link to post Share on other sites
