My wife's box has a very intermittent problem, when booting from the Maxtor IDE hard drive. This has been going on for about 2 1/2 years.... The box is a Compaq EVO D300v for the Enterprise. When it boots, there is a SMART advisory from the BIOS that says failure is immenient. Occasionally, it will not boot, because the BIOS does not see the hard drive. I replaced the EIDE cable, but the problem of sometimes not seeing the hard drive on boot continues. I suspect it has to do with something loose in the electronics of the drive, because if I press on both ends of the EIDE cable, the problem goes away and then it will boot OK. The box is currently M$ Windows only. I just booted it from my Knoppix Live CD and ran smartctl on it. Below are the results. When I ran the Maxtor Diagnostics on the hard drive, 3 times, each time the quick 90 second SMART test said that I should run the Read test, which takes about one hour. Each time I ran the Read test, it passed OK. 3 times. Should I suggest to my wife that she let me replace the hard drive, now, at her convenience, before it fails completely? Is there anything in the smartctl results that indicates that is not the appropriate thing to do, considering the length of time this problem has existed? I did not run the Maxtor Burn In test or low level format, because I do not want to reinstall everything on this hard drive. The smartctl results certainly seem to indicate something badly awry, which the Maxtor Diagnostics, on the Read only test, did not pick up. TIA!
