Modern disk drives have internal bad-block remapping. As manufactured, there is a reserve of sectors available to use when the computer requests a block known to be bad (based on an record of bad blocks maintained by the drive itself). The initial bad-block remapping is done during manufacture (after burn-in, I think). Each manufacturer has to set a standard for the number or percentage of blocks that can be bad and the disk still shipped. (Very few high-capacity drives are literally defect-free.) The list of mapped blocks can be added to during ordinary use when an in-use block becomes unable to accurately record data.
Is there any way one can check for such bad blocks since as you say the badblocks program won't catch them? As I wrote: smartctl didn't report any problems either. The way you describe it, such errors might/should be a part of smart?
Check the support downloads on the manufacturer's web site for a diagnostics tool. Dylan
