About 2 years ago I had a disk fail, not 100%, but intermittent problems. So I replaced it. The replacement started acting up about 6-12 months ago. Read errors about every 1-2 months, finally it went off-line. But, intermittently. I did think it was odd that the drive in the same position was failing, and with similar problems, but figured it was just a quincidence. Today I replaced it, after replacing it, I had some problems. It is in a case with 6 other disks, so I could tell by the LEDs that the replacement drive was acting wrong, intermittently. I determined that the Molex power plug going to the drive was causing the problems. What a pain! So, the 2 drives that I replaced may have been good. The first drive I took apart. I have the magnets to prove it! But it may have been a good drive! To make a long story short, check the cables for failures, including the power cables. The drives are Seagate, and I have at least 26 in service, so 2 failures out of 26 in 3 years is not so bad. However, if the Molex connector was at fault, then 0 failures out of 26 in 3 years, is just fine. The drive is model ST118282LC, MTBF 1,000,000. I think with 26 drives I should have 1 failure in about 4.4 years. The drives have a 5 year warranty, but they are OEM, so I get nothing. I am not the first owner, but they were unused. And I bet they are about 5 years old now. Too much info? Sorry. Maybe I need a blog? :) Can anyone spell "quincidence"?
