I'm not sure if I'm posting this in the correct forum, please move it if it is!

So here's what happened. I have a 500GB portable external hard drive formatted in HFS+. I *accidentally* formatted this drive into FAT32 in Ubuntu. I am trying to recover the data that was on this drive.

I have tried using Data Rescue 3 for Mac and have had the following results. First, I should mention that the Mac cannot read the hard drive, and Disk Utility tells me the drive needs to be reformatted. So I'm guessing something is corrupted with the FAT32 format. I used Data Rescue 3's deep scan option and it was miraculously able to see all my files, intact, under "Found Files". It also had some "Reconstructed Files". I recovered everything, BUT the problem is, all the files under "Found Files" were corrupted, even though the file sizes seemed correct and it had its original filename and everything. The stuff under "Reconstructed Files" did not have original filenames but were able to be opened.

Most, if not all, of the files I need are under the "Found Files" option. Is there still a chance of recovering these files? I have one last idea, which is to use Disk Utility to reformat my hard drive as HFS+ and then re-scan it with Data Rescue. But I want to know if I can try anything else first. Any help will be greatly appreciated!

A hard disk, external drive, or other type of storage media can have one or more formatted partitions. At least one partition must be present in order to store data. This means that your storage media will have at least one (i.e. container) configured to use a specific file storage system such as NTFS, FAT32, or HFS+. Every drive comes with one configured partition. However, you can configure more than one for the drive. Each partition is able to have its own file system as well. In your case, it's HFS+.

 

Sometimes the files can become lost or be unintentionally removed from the drive or storage media partition. In other instances, an accidental Mac reformat will wipe anything previously store on the partition. What options are available for recouping your data? Formatting essentially prepares that partition to store brand new files. Once this is done, the operating system cannot locate any of the information previously stored on it.

 

 

The only way to get this data back is to use a recovery tool capable of searching the partition for retrievable information. By using a utility designed to recover files the operating system cannot find, it is possible to get the lost or deleted files back and store them to safe location.
