What the hell is TLER? It's a feature on some Hard Disks from some manufacturers (like Western Digital Green drives)
I came across then when I put my
NAS together. I have four 1.5TB WD15EADS disk's in my NAS, and have turned TLER -on- for each disk before building it in to my array.
"It is important to understand that TLER should be "Enabled" for a hard disk if it is being used in a RAID array to prevent the recovery time from a disk read or write error from taking too long, causing the RAID controller to flag the drive as failed, which drops the drive from the array."
