hello my SATAII (hitachi) drive is producing unusual (and loud) click sounds - or 'double-clicks', to be precise. these are accompanied by other symptoms - it appears the fan frequency slows down for a fraction of a second as the HDD produces the click. this SATA drive is one of three drives running in the computer, and is the most recently purchased at that (around a year and a half now); the remaining (IDE) drives are much older, however never show any signs of malfunction. i guess there's no point asking whether the data are at risk. i'd be more curious to find out the cultprit, as i wouldn't want to run into the same problems if i choose to replace the drive with a new one. it just appears as though the electricity current going to the drive is being cut for a fraction of a second, as the clicking reminds of the sound produced when a computer is switched off abruptly. could it be the PSU is not sufficient to run the system? but why would just the SATA drive be affected by this (as all the remaining drives / connected devices seem to run seamlessly)? (btw. i'm using an asus p5w deluxe motherboard with win xp sp3). thank you!
