March 12, 201016 yr Looks like a lot of disk errors to me (not linux savy). Any ideas? syslog-2010-03-12.txt
March 12, 201016 yr Since they are all media errors, it appears as if your drive is having a lot of trouble reading its platters. Get a smartctl report on the drive and you'll be able to learn if it is re-allocating sectors internally and its true health. smartctl -a -d ata /dev/sdc

March 12, 201016 yr Since I'm not seeing re-allocated sectors, I suspect a bad or loose cable to the drive.
March 12, 201016 yr Author Thanks, I'll borrow a cable from a friend and see if that fixes the error.
March 12, 201016 yr You probably already know this, but be sure to stop the array and power down before changing cables. Also be careful not to dislodge another cable while replacing the first.
March 12, 201016 yr There are 509 pending reallocations ("Current_Pending_Sector"). Not exactly sure why none of them have been reallocated yet. The drive looks bad to me.
March 12, 201016 yr There are 509 pending reallocations ("Current_Pending_Sector"). Not exactly sure why none of them have been reallocated yet. The drive looks bad to me. I missed that. They will only be re-allocated when the drive is written.
March 13, 201016 yr Author So does the drive definitely got bad sectors then? It was a brand new drive, probably just out of newegg's 30 day warranty (still under manufacturers).
March 13, 201016 yr So does the drive definitely got bad sectors then? It was a brand new drive, probably just out of newegg's 30 day warranty (still under manufacturers). Yes, definitely a bad drive. And we can see it is new... The power-on hour counter is 33. Joe L.
March 14, 201016 yr Author Thanks guys, replacement drive is on the way. As of today the drive is now up to 3000 sectors waiting to be re-allocated.
March 14, 201016 yr Thanks guys, replacement drive is on the way. As of today the drive is now up to 3000 sectors waiting to be re-allocated. You don't want that drive in your array. Good thing the replacement is on the way. Remember, when you put in the replacement, use the "Start" button to rebuild the old contents onto the replacement. Do NOT use the button labeled as "restore". It has nothing to do with reconstructing data. It is actually a "Set Initial Disk Configuration" button... It immediately invalidates parity. Joe L.
