Got some VERY hot SATA disks.

If you're already beyond that, the contents of /etc/fstab and/or /etc/mtab contain the filesystem types for all partitions the computer knows about. Alternatively, "df -T" can be used to show the filesystem types on the currently mounted devices. From there, it strongly depends on the filesystem type. xfs has tools to let you navigate the whole tree at will, but AFAIK, the other types will involve lots of manual labor.

You may be able to recover some text based files from there, but binary data is pretty much a lost cause. There are a couple of programs that can recover files from a damaged image which work reasonably well on small files with a wellknown structure (like JPEG images). Testdisk (Debian's package name. No idea what the others call it) has a scanner that works specifically with photo files. [link\|http://foremost.sourceforge.net\|Foremost] works by extracting everything that fits the signatures you specify, but that includes all echos caused by editing, moving, deleting, etc.
Post #290,521 by crazy 8/8/07 11:56:57 PM Reply	I wasn't planning on recovering them I simply wanted a listing of what files were affected. I knew it was only a few based on the sector count, so I was hoping to avoid the multiple restart of rsync. That's OK. All fixed now.
