I live close to the warranty center so I dont mind the wait, but I'd rather not waste my time if this is a perfectly good drive that had some goofy random sectors. Or should I consider any ba sectors an RMA if I can? Quote Link to comment
Joe L. Posted February 17, 2012 Share Posted February 17, 2012 It appears as if all the unreadable sectors were re-written in place. Quote Link to comment
internetfriend Posted February 17, 2012 Author Share Posted February 17, 2012 Yeah, it was. I'm doing a final preclear on the cache drie now to see if i can correct that pesky bad sector. I'm hoping/assuming most of these came from a poor PSU and not actually bad drives, but I'm still wondering If I should RMA that parity drive. I guess I'll just keep an eye on it, I still have 1.5 years of warranty on it. Quote Link to comment
internetfriend Posted February 19, 2012 Author Share Posted February 19, 2012 Follow up! I'm guessing I had a PSU giving up overall like a few of you guessed. Preclear of parity drive and cache drive cleared pending sectors on the new hardware. parity sync went without issue and a parity check passed with 0 errors. Only remaining thing mymain throws as an issue for the cache drive is a "soft_read_error_rate=1" but I'm assuming thats ok, all sectors are corrected. syslog attached for closure. Thanks everyone for their help! Fingers crossed I dont come back 3/1 with something when the new party check hits. syslog-2012-02-19.txt Quote Link to comment
