Hi. I had this USB hitachi hard disk that i use mostly for backups since like 5 years and it has worked perfectly so far, yet last week when i plug it in i heard it making the horrible "Cloc Cloc Cloc Cloc Cloc" sound and unplug it immediately Since my last laptop disk and my friend's Usb HDD die in from of my eyes by the "click of death" i... well... panic lol When i calm down i plug it again but this time it mount perfectly with no abnormal sound at all, i copy and burn all the essential data from it in case of it will fail again and then i disconnect it and have not connected it again since then. Now, my question is... was it really a click of death or WTH was that? since it worked perfectly the in second attempt ..and can i check it with some utility? is Apple's DiskUtility the best choice or is there anything better to verify is the disk is fine? DU says that the SMART is unavailable so i don't know Thanks!
