Fun and games being played by the 'regulars' here! https://discussions.apple.com/thread...2#251567212022 Can *YOU* get to the link like 'dialabrain'? puzzled Disk Drill is described in Wikipedia. https://en.wikipedia.org/wiki/Disk_Drill_Basic Whether this is a good idea, would depend on whether the file system in question had a "weakness" where a failure could be fixed by it. For example, if the underlying clusters were damaged or overwritten, you're out of luck. Here's another example. A prototype of sorts. https://www.systutorials.com/docs/linux/man/8-e2image/ And its NTFS equivalent. https://www.systutorials.com/docs/li...n/8-ntfsclone/ ntfsclone --metadata [OPTIONS] SOURCE What that gives you, on a second disk, is a "picture" of the system, but all the clusters are zeroed out. So if you wanted to look at "myholiday.jpg", the file would be empty. It would have a size, like 74,567 bytes, but every byte read from the skeletal clone would be a zero (or whatever). For it to be actually zero, you'd have to erase the destination drive first and paint it all zero, before doing the ntfsclone. To do that on NTFS, at a guess you'd need $I30 from every directory entry, as well as the $MFT. And you'd be avoiding backing up the data clusters, in the name of "doing a fast backup of just the metadata". And while this is amusing and all, it still requires consolidation work (since the metadata snapshot hardly ever matches the actual file system holding the clusters). An "expert" then has to walk the tree, and zorch the materials that no longer make sense. Who knows, if the $MFT was erased, maybe it's a good idea, or maybe just replacing the $MFT with a backup copy, is more or less as good. I don't think I've ever had a situation where working this way would have made a difference. Things like "undelete" in NTFS, rely on the fact that on erasing a file, NTFS is very lazy, and just flips a byte on the $MFT entry, declaring the entry invalid. But all the materials to restore the pointer are still there. A backup of metadata is not required in that case, to "undelete" something that wasn't done with a secure erasure method. I think there *is* some value in doing certain kinds of backups. For example, backing up just the MBR could be useful to some people. Especially when you discover that TestDisk is not able to synthesize the correct MBR when you actually need that to be done. The same might be said for backing up a MBR+GPT partition table (128MB), that is, if you can figure out where it is, and figure out how to snapshot it. It doesn't wiggle around, so should make an easy target. ******* And a word of warning for you. *Don't* use the Gparted on a Knoppix disc, on your Mac file system. I presented a year 2003 Mac file system to Gparted, and I was surprised how GParted was all ready to work on it! I thought it was a miracle. until Gparted *destroyed* the partition table at the front :-/ So while some of these programs may choose to "tease" you with capabilities, you should have a suitable backup before doing that. Fortunately for me, I had multiple copies of that file system, so my blood pressure hardly even spiked. In times past, the program would have refused to touch the disk. Any time you use Disk Utilities of various sorts, they need to be "dialed in". Trust no one. When I bought a copy of Acronis Disk Director, it had a function to "change the cluster size on the fly". I was suspicious (that's hard to do). I ran it, and everything at first looked good... until I looked at some DLL files in the System32-type area, and they had "zero size". Nobody makes DLLs with zero size, and I knew I had ruination. Again, since I had a backup, no harm was done. It was pure luck that I happened to notice that. I didn't have a test plan that said to check for that. I likely would have discovered on a reboot, that it was trashed. And in case you ask, why would you need to change the cluster size, the cluster size on C: is normally 4096. By accident, I installed Windows 10 on a partition where the cluster size was 65536 (a backup data partition). And on a certain release of Windows 10, the OS no longer tolerated that situation. That meant I needed to change it to 4096, so the next OS upgrade could work. And ADD let me down, and the transition could not be done that way. Paul |

That means its "special properties" are not being used, and it's turned into an "ordinary" program. If the $MFT is trashed, then it can only do what other utilities do. Namely, look for clusters with a recognizable signature, and assume the adjacent clusters are part of the same file (which they might not be). If a disk drive is highly fragmented (which your builder-friend might have for a partition state), then certain kinds of data recovery produce mostly broken files. I've gone through a 100,000 fragments like that in a recovery attempt, and the recovered material was "mostly crap" and unusable. For the recovered data, you'd have to check each file to see whether it was intact or not. If more of the file system was functional, then perhaps a ddrescue method would be a way to do it. (ddrescue copies sectors until after multiple applications, it cannot recover any more sectors.) Then you work on the "copy" of the partition, on a disk which is healthy. Using programs like Recuva and PhotoRec, those are examples of free programs with slightly different approaches for data recovery. I don't know enough about how directory entries (files with a $I30 entry), point to data files. The $MFT does have a cluster list, which suggests the $MFT is pretty important. Some other file systems, the linkages are distributed, and some "experts" at work, could repair those just as smooth as could be. They took a course, which included how to do that :-) And, they were pretty good. They were put out of a job when better file systems with journals came along, as the OS was better able to unwind a mess at startup. We didn't have to trouble them with that sort of data recovery any more. Paul |
