It's not a particularly researched area, but my impression is that HDDs can die prematurely or slow down to a crawl if you let them remap bad blocks. You should manage this in software yourself, don't risk overwriting bad blocks and letting the drive remap them.

- zzzcpan 7y agoFirst time I suspected that problem, I wrote a tiny program that scanned the disk for slow blocks then marked as bad each block and extra megabyte to prevent disk's readahead from hitting bad blocks too. You are probably using a kernel filesystem, some of them let you provide a list of bad blocks to mark and avoid, I haven't tried that though.
