I have a 1TB laptop hard drive that's in a pretty bad state according to SMART data, with issues like reallocated, pending, and uncorrectable sectors. However, I noticed there are still some healthy regions on the drive. I'm wondering if it's possible to partition the drive so that I can only use these stable areas while avoiding any bad sectors entirely. I know the drive is considered disposable, and there's no need for data recovery since I got it for free and it doesn't hold any important information. I'm okay with sacrificing some capacity for the sake of stability. Is there a way to reliably create partitions that exclude the bad areas? If so, what tools or methods would I need? And if not, what would prevent this from being achievable?

If you're using a Dell Thin-station, overheating could be a concern. I’ve experienced similar symptoms before it started throwing temperature alerts. Just something to keep in mind while you're troubleshooting.
You might think you can carve around the bad LBAs, but honestly, with the spare pool already exhausted and sectors failing, it's pretty much a lost cause. Better to clone what's still readable with ddrescue and then just retire the drive. It's not going to hold up for long, and trying to salvage it with partitions could lead to more problems.
It doesn't have any data, though. Why not try and see what you can do?
A drive that is failing is typically going to cause issues no matter how you try to partition it. The uncorrectable errors and no spare sectors mean that whatever mapping you do is going to be just temporary. If you're really set on this, tools like GParted or specialized partition managers could work, but keep your expectations low. It's risky business!
Trying to revive a hard drive that's showing bad sectors usually isn't worth it. Technically, you might get it to work for a short project, but the reality is that drives in active degradation will not cooperate with any attempts you make to map partitions. You'll have good sectors one day and they could fail the next. I'd suggest finding a reliable replacement instead.
I know it's not a perfect solution, but why not at least give it a shot?
Just to clarify, I’m dealing with a 2.5" HDD, not a specific laptop model.
