Does a RAID 5 rebuild include deleted data?

I understand that common data deletion removes the header and leaves the data. Also most disk mirroring software will include the deleted data. The only real way to normally get rid of deleted data is to copy the existing data to a new drive. If I choose to replace the drives in my array, would the rebuild process include deleted data?

Thanks. We'll let you know when a new response is added.

As the rebuild happens at the block level, not the file level anything that should be on the disk, including deleted files, would be copied to the new disk.

    When you "replace" drives, are you meaning that you are replacing the RAID array and restoring data from backups? Or are you replacing drives, e.g., due to a drive failure, and letting the RAID controller "rebuild" data on the new drive? -- Tom

    You should already have backups of your disks in another location.  So, if your RAID did crash, you "hopefully" did have a daily, weekly, and monthly backup on file, right?
