So I'm running Data Rescue on a hard drive that had some files trashed, and then the trashed emptied. So I ran the deleted file scan. It took about 2 hours to scan the whole drive, which seems reasonable to me. The drive is 320 GB and it was reading the drive at between 70 and 50 MB/sec, which seemed fast. But now I'm doing the actual recovery, and it's going absurdly slow. Like tens to hundreds of kilobytes per second. At this rate, it will literally take weeks to recover all the data. I don't understand why it's going so slow? The drive isn't damaged at all, I'm only using data rescue deleted files. Why isn't it still doing the actual recovery at 70 MB/sec, instead of 15KB/sec??
