See what
Code:
echo {39594646..39594656}
39594646 39594647 39594648 39594649 39594650 39594651 39594652 39594653 39594654 39594655 39594656

prints - 11 words, 99 chars.
Code:
echo {39594646..585912500}

would try to create 546317854 words and hereby blast any LINE_MAX or ARG_MAX system parameter... and obviously exhaust memory management on your box.

Good point.
Further, the repair function exchanges a defective sector by one from a reserve track. Where it tries to read the defective sector and copy its contents to the replacement sector. But might fail: data gets corrupted.
There is a couple of reserve tracks that might hold a few hundred sectors. If they are spent then further repairs will fail.

Good catch. Thanks.
I am running it in parts now. This time {39595001..39599999}
Probably all blocks may not be corrupted. But as of now it is running. I will update this post, once I have something.
