Ask about the issues related to scandisk and hard disk bad sectors.

Asked: After using scandisk to scan and finding bad sectors, will DOS no longer attempt to store data on the bad sectors?

Yes, scandisk is still useful for floppy disks.

Okay, thank you!

If scandisk is used to scan for bad sectors and then Windows 95 is installed, will the Windows 95 installation program also avoid hard disk bad sectors?

Yes, it's not installed on the bad sector.
It is suggested to use a tool software to mark the nearby several areas as bad sector marks as well, or simply divide this small piece of space and hide it.

Which tool software can be used to mark the adjacent areas as bad sectors?

It is also somewhat useful for hard disks.

I've tried it, but it doesn't work.

Many disk editors can mark specific clusters as bad sectors.
If a hard disk has problems, it's best to take it for replacement or throw it away.

What do you refer to?

It won't be used again. However, if the bad sectors are relatively concentrated, it's better to partition them out and isolate them.

Don't give up easily, it might be a logical bad sector. Erase the hard disk with Norton's wipeinfo, maybe it will be okay. The hard disk I'm using now also had bad sectors before, after erasing it, everything was normal and it has been used until now

Final choice, low-level format. DM is my favorite, heh heh! This is a last resort!
