Hi guys, first post here.

Will any drive wiping software such as HDDErase or the erase function in MHDD "fix" the green slow blocks in the MHDD scan?
I've been reading a ton of posts here about using the secure erase within MHDD but i can't get around the password. anything I do it says "Fail." from what I read it's the PC Bios freezing the drive to protect from malicious invasion, but I don't know how to get around that.
I have a bunch of 250GB IDE that go into intellex camera servers for video storage and the OS, and with the cost of replacement drives at around $45/ea, I am trying to learn on the fly how I can correct the ones I have. Most only have 1-3 Green blocks, but that seems to be enough to cause freezing issues and lock ups in the field. My work has been using killdisk for wiping and a Kanguru clone machine for mass erase and scan, but both seem like garbage to me. I use MHDD as the final call for sending a drive out, but I don't feel like Killdisk is doing enough before I scan it.

Can wiping a drive with a high quality program take care of a few green blocks?

Thanks!

The answer is no. I do mass refurbishing of drives - complete factory recertify procedure - and specialized tools + proprietary info are required to do the right thing. And it is not 'on the fly'.

I'm no "guru", and wasn't implying that it's easy stuff. I have read a lot of posts on here and I respect the complexity of it all. I don't have the time to invest to become one of you, I am simply looking for advice to do the best I can with what I've got. I wouldn't have even addressed it to this extent if not for you adding "And it's not 'on the fly.'" What on the fly means, is I am learning as I go without any HDD specific background. not referencing this craft as on the fly stuff.

You have done everything possible with what you have. If it doesn't still work, it's clear that you need some other resource and it's not matter of advice. Some things can be fixed "at home" with simple tools, other require to be sent to a service center, that's it.
