[ILUG] Recovering Reiser File System

[Ian Spillane]

I'm not an expert either but you can at least maybe copy the entire disk contents to a file in linux as a backup of the file system if you are worried about further corruption. 

The disk contents itself can be read without reference to the filesystem at /dev/hd[a]

I have an ntfs disk that needs repairing eventually by writing a program to extract information (photo collection!) directly from the disk and at least linux provides a native way to do this. 

Someone else might have specific commands we can use, but in initial tests I see at least that cat /dev/hdb works and the data is visible. 

My error was an MSbackup which disappeared on the same night as a harddisk problem. Scandisk then erased all trace of the file index in an effort to "fix" the disk. A lot of it is compressed and a mess but I'm hopefull that jpgs will be intact and uncompressed by the filesystem and some basic C should retrieve the file data. 

Every cloud has a silver lining: I abandoned MS and found the wonderful world of linux and computing is fun again. 

Any ideas would be gratefully received.

Subject: [ILUG] Recovering Reiser File System

Hi,
My reiser file system under Suse 9.2 got corrupted over the weekend and
I am unable to retrieve any data from it. I am getting an  Input /output
error when I try to copy files to a new partition on a separate harddisk
using Knoppix or Ubuntu. Two separate partitions, the / and /home, got
corrupted at the same time. As they are both on the same hard disk it
may be a disk fault.


Because it's on a home machine I never bothered to do a backup. So no
its sinking in how much data I am in danger of losing. 


Is there a systematic way of being able to recover as much of the files
as possible? I am very apprehensive of about trying to recover the files
as there is a danger of making the current problem worse. 

As I am not an experienced Linux hacker I would appreciate any advice on
how to recover my files.
