What to you mean?? Have u partitioned a drive mistakenly? or If there is a drive which your computer wants to partition before using it? or Smthing else??
Yes. Off-hand, I don't know of any free tools or if they're on a recovery CD you can obtain. I do know that data retrival specialists can do it, but that service is very expensive.
i used Vista's formating tool to format a partition, and I want to undo that format I did I was trying to recover data from that partition, but it wasn't formatted, so i thought it had to be formatted for the recovery tools to be able to find it, after using a bunch of recovery tools, they weren't finding the data, so now I want to undo a format i did on that partition
