I've been playing a lot with deblet lately and other OS's which has required multiple flashes of the boot menu. Today when flashing, I noticed that I've got a couple bad sector in the initfs. My question is this: Is this a real problem, I know that sectors go bad all of the time. But, is this a sign that the flash ROM on my device might be getting ready to kick the bucket?

As a side note...the device has been taken care of, so I doubt the problem is related to some form of physical damage to the device.
