It probably wasn't one of those, but just like it. The executable was something like sdisk or sfdisk. The claim to fame for us was using it to fix partitions that became corrupted that fdisk couldn't see or fix. I believe it was around the time of the first EIDE disks that needing the WD code for them to be fully visible by the PC. I think the problem was when you wanted to remove that, but I can't remember. I just know we though we had a systemic issue and were going to have to toss a lot of drives and then somebody found this program and it saved our a$$. Anyway, the "long fix" is more than 50% of the way through and it hasn't said anything, yet. I think it gave up and stopped before it finished last time. I don't recall it going the full 2 1/2 hrs estimated.
