Converting back to NTFS without formatting?

Currently my hard drives have no file system structure. This is due to a bad linux install.

Using an external program, I can see that my data is still on the hard drives, but it’s inaccessible so formatting is NOT an option.

I would normally just use the “convert” command but to do that, you need a drive letter but my hard drives don’t have one.

  1. How can I convert my hard drives to an NTFS structure, without formating? Partition magic doesn’t work for this.

  2. If I delete the partition, will that also delete the data found on the hard drive?

Thanks!
