Just try it. You can try R-Studio Emergency, a live CD, to _check_ if there is anything to restore. This step is for free, as you don't need to buy it. Also there's no need for installing anything on some Windows. However, there are tools that can be used on FreeBSD (if you can put the disk into another system). Note: Do not write to that disk! If possible, make a dd image of the disk and work with the image, do not _alter_ the original disk in any way. Every little wrong step can decrease your chances for recovery. I came to this list many years ago with a recovery problem, and have learned a lot since that time (as I also had no backup and still got my files back). So I'll try to give some suggestions. But remember that it depends on your _specific_ setting on what will possibly work and what won't. As it has been questioned already, formatting can have several meanings, especially in Windows land. The more actual content of the disk got overwritten, the worse it gets. So if you've stopped the installation at some point, it's still possible that your data can be located. Allow me to introduce a few tools to you (my meanwhile famous list of data recovery tools which I've posted some times on this list): A worst-case tool to recover data (not file names, but file content) is testdisk; in ports: sysutils/testdisk. It's also on some diagnostics and recovery CDs like UBCD. You can also try this: fetch -rR device Also recoverdisk could be useful. The ports collection contains further programs that might be worth investigating; just in case they haven't been mentioned yet: ddrescue dd_rescue - use this to make an image of the disk! magicrescue testdisk- restores content recoverjpeg foremost photorec Then also ffs2recov scan_ffs should be mentioned. It's possible that the disk contains some information to restore the initial UFS file systems. And finally, the cure to everything is found in The Sleuth Kit: fls dls ils autopsy In worst case. Just in worst case. Keep in mind: Read the manpages before using the programs. It's very important to do so. You need to know what you're dealing with, or you'll probably fail. There is no magical tetroplyrodon to click ^Z and get everything back. :-) Proprietary (and expensive) tools like R-Studio or UFS Explorer can still be considered worth a try. Their trial versions are for free. UFS Explorer even works using wine (I've tried it). If you have one or two spare disks, initialize them in FreeBSD. Make a dd image of your disk to the 1st disk. Use recovery tools to write their results on the 2nd disk. Disks are cheap, at least your data is worth more than two disks. And you're going to need the disks anyway. :-) I wish you best luck to get your data back. I can fully understand how frustrating such a situation can be. -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ... ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
newfs'ed partition, recovery?
I accidently newfs'ed a partition I didn't want to newfs. Is there a way to recover the data on that partition? _ Jon ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
partition recovery
Hello, I have a hard disk that had a complete FreeBSD system on it. Earlier today, I accidently deleted and created a new slice on top of the one that was there. Now, the OS thinks there are no FreeBSD partitions there, only empty space. I did *not* do newfs, so there's a really good chance that those partitions and all their data are still there if only I could find some way to tell that to the disk. I tried the sysutils/gpart port, but it appears to only recognize and operate on slices (PC-style partitions), not FreeBSD partitions. I have a blank disk just like the one I'd like to recover and I have the numbers I need to re-slice and re-label it identically to the other one, down to the exact bit. So I'm more than happy to experiment with that one prior to performing suggested operations on the real thing. I have the feeling this may involve the fdisk or disklabel programs. If so, know that I'm none to handy with them but would appreciate pointers to some decent documentation on them aside from the man pages. Thanks in advance for your time and help. P.S. Won't be able to reply until Monday. -- Charles Ulrich System Administrator Ideal Solution - http://www.idealso.com ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
Re: partition recovery
sorry for swapping slices/partitions - it was
too late yesterday and I had too much work...
Here's more explanation:
On 2003-07-13 06:48, Malcolm Kay wrote:
there was windows 2000
[ ntfs ]
I made some place for FreeBSD
How?
I used partition magic, I resized first dos-partition
and created second primary dos-partition (without
extended dos-partition).
In FreeBSD terminalogy this is now 2 slices:-
[ ntfs ][ ufs=ad0s2 ]
I created slices
In FreeBSD terminology created partitions or
more specifically BSD partitions.
right, that's what I did :)
[ ntfs ][( s2a )( s2b )... ]
after some time I removed win2000 - and just
did newfs on first partition (no repartitioning,
no slices - only newfs)
On the first slice -- no BSD partitioning.
right, the question is - is that ok, to do that?
I mean - to newfs without bsd-partitioning?
[ufs=ad0s1 ][( s2a )( s2b )... ]
The MBR (master boot record) table will still have
the first slice marked as ntfs unless you ran fdisk to
change it.
do you mean - the main dos-partition table?
I *think* I fixed it using gpart. The linux sfdisk says
now:
fake:~# sfdisk -d /dev/hda
# partition table of /dev/hda
unit: sectors
/dev/hda1 : start= 63, size=125821017, Id=a5
/dev/hda2 : start=125821080, size= 3903795, Id=82
/dev/hda3 : start=129724875, size= 30346784, Id=83, bootable
/dev/hda4 : start=0, size=0, Id= 0
after some time I wanted to install debian GNU/Linux
(this is test-box)
[ufs=ad0s1=hda1 ][swap=hda2][ext2=hda3]
and here something bad happened during installation
(few reboots/kernel panics and so on)
It seems you have now assigned all slices to Linux
at least in your mind. But what types does fdisk think they are?
I didn't touch the ad0s1 when installing linux,
I just removed ad0s2 and placed two linux-partitions there.
(hda2 - linux swap and hda3 - linux system)
(I wanted to use ad0s1 to move some data to the new system,
I expected linux to be able to mount UFS - at least r/o)
it CAN mount it as NTFS (and I can even see
some windows files!)
- freebsd can see it as UFS but cannot mount
Where is FreeBSD? -- it appeared you had given the FreeBSD slice
ad0s2 over to Linux swap -- but then I'm not knowledgable with
respect to exactly what Linux means by hda2.
I run freebsd from live-cd now (as I explained above
I removed freebsd slice (ad0s2) with all bsd-partitions
inside).
('bad magic number' or bad superblock),
using backup superblock
(-b 32) doesn't work.
What can I do to recover data from the first partition???
What data? -- the original ntfs data or what Linux may have installed?
I suspect that in either case it is now pretty much corrupted. The semblance
of windows files will have a scattering of blocks over written by newfs.
I want to recover files from UFS filesystem on ad0s1. It was NTFS before
but as I mentioned before - I did newfs, so It became UFS. I think
the windows files that can be seen are just shadows of old days
(blocks that were not overwritten during using the slice with
FreeBSD). I looked at the slice with lde (linux disk editor, I
don't like the tool but I couldn't find anything more user-friendly)
and it seems that the files I saved to UFS are in good condition.
I hope the case is more clear now :)
What do you advice to do now?

partition recovery
Hi
I have a problem with UFS partition
(I can't access it). I'll tell you the story:
there was windows 2000
[ ntfs ]
I made some place for FreeBSD
[ ntfs ][ ufs=ad0s2 ]
I created slices
[ ntfs ][( s2a )( s2b )... ]
after some time I removed win2000 - and just
did newfs on first partition (no repartitioning,
no slices - only newfs)
[ufs=ad0s1 ][( s2a )( s2b )... ]
after some time I wanted to install debian GNU/Linux
(this is test-box)
[ufs=ad0s1=hda1 ][swap=hda2][ext2=hda3]
and here something bad happened during installation
(few reboots/kernel panics and so on)
Now I cannot mount ad01s/hda1 partition -
- linux sees it as NTFS partition, more -
it CAN mount it as NTFS (and I can even see
some windows files!)
- freebsd can see it as UFS but cannot mount
('bad magic number' or bad superblock),
using backup superblock
(-b 32) doesn't work.
What can I do to recover data from the first partition???

Probably because it is still marked as ntfs in the MBR.
Change its type with fdisk.

You seem to be confused with slices and partitions -- but it IS
confusing. Just remember Microsoft partitions are slices in the BSD
world.
