Recovering data from old postgresql install
location: ubuntuforums.com - date: May 5, 2010
I was previously running postgresql 8.3, but upgrading to Ubuntu 10.04, has installed postgresql 8.4 and I'm now unable to start 8.3.
I don't mind using 8.4, but I need to recover the data from my 8.3 installation, But I'm not sure how to do this as I can't start the 8.3 server, and 8.4 can't read my old data directory.

Copying data from old linux machine, permission denied!
location: ubuntuforums.com - date: April 28, 2012
my mom was using ubuntu on her old toshiba laptop, and unfortunately it completely died recently. i pulled the harddrive from it and put it in a case, and am looking at the files i want to copy to her new pc. But alas, i do not have permission to even read them!
can i force my way in so she can have her documents etc or does she just have to pay the price of being careless with her data?
Also, i am a relative novice, ive poked around with linux many a time but have never reached a level of proficiency that i see from most users here, so id prefer if theres a solution simple enough to do through the GUI, and off the live cd but beggars cant be choosers.
thank you for your time!
Recovering Data from Remaining RAID 1 Disk
location: linuxquestions.com - date: May 2, 2009
A while back, I had a PC with two hard drives configured in a RAID 1 array with mdadm. I stored a lot of data there, though nothing too important. The OS installation went south at one point and I installed something over it. I left the RAID array untouched but notably didn't backup my mdadm.conf.
A year or so later, I now have a new PC with a new OS installation and only one of the disks remaining :-) I would like to mount the remaining disk, pull the data off and start using the disk for other purposes. Everything I'm reading tells me that I'm fine as long as I either have or recreate mdadm.conf AND as long as I go buy another disk to replace the missing one.
I've also read allusions to the ability to tell mdadm to mount an array with "missing disks" but haven't seen any instructions on how to do so. I've tried just popping the disk in and mounting it like a regular disk but mount refuses to do so, citing that it is of type "Linux RAID" or somethin
Recovering data from dead NAS
location: ubuntuforums.com - date: September 16, 2012
I'm trying to recover the data from my recently dead Seagate Blackarmor NAS 110.
It's got a 1TB SATA drive, which I had previously assumed was formatted NTFS.
The NAS died today, and while it won't be the end of the world, I have over 650GB of data that I'd really rather not lose.
I removed the drive (no easy task) and hooked it up inside my desktop. Much to my everlasting surprise, it's not formatted NTFS. It's actually got 3 ext3 partitions and a linux-swap partition. (plus a couple chunks of unallocated space)
What's throwing me off is that even though there's one partition that is obviously the data partition at 928GB, and the others are quite small, gparted shows that all 4 partitions are flaged as RAID.
Does anybody have any idea where I should get started with trying to get these partitions mounted so I can move my data to a new NAS?
[SOLVED] Recovering data from MD array (using Knoppix)
- date: June 2, 2011
I have been searching the forums w/o success for some help on this old problem I have. I had a major OS crash (Gentoo) maybe 2 months ago and completely neglected my system. Now I want to recover all my mirror raid data back so that I can restore the system.
My plan is this:
1) copy all data so that I can have a backup
2) rebuild system with some HW upgrades
First step is to get the data out. I managed to boot with Knoppix and I have full access to my ext2 partitions. My mistake was to create the mirror partitions and these are not working now.
I copied my /etc/mdadm.conf into /etc/mdadm/mdadm.conf in Knoppix and then tried to start the services. This is what I got:
:~$ /etc/init.d/mdadm start
:~$ /etc/init.d/mdadm-raid start
Assembling MD arrays...failed (failed to load MD subsystem).
I can see the partitions:
:~$ fdisk -l

Recovering data from lost+found directory on ext3 fs
location: linuxquestions.com - date: July 31, 2009
I have a very strange external USB drive which I know is the enclosure as the internal drive is a Seagate 160GB IDE HD.
I recently pulled this drive out of a dead server as I was using it as an nfs export but now I have to use it as external USB HD since I don't have any other machines to put it in.
The weird thing was that one folder after powering on and auto-mount-usb kicked in, became locked as permissions got all screwed for some reason or other. Even after unmounting before disconnecting it.
Anyway some inodes became unattached and the boot record got all mangled.
I ran fsck /dev/sdb1 on it and attempted a manual repair so I pressed yes to everything that it wanted me to which in turn deleted inodes and other bits and peices.
I then ran fsck -a /dev/sdb1 on it and it claimed that there was a large percentage of non-continuous information.
I guess I should have run e2fsck -p /dev/sdb1 instead but what is done is done and now I have a deleted folder and 4GB of data in lo
Recovering Data from a hard drive
location: ubuntuforums.com - date: March 14, 2013
First let me provide a bit of a back story. A few years ago I bought a D-Link DNS-323 NAS so that my wife and I could keep our photos and important digital media safe (ran it as RAID 1). The last few years it has been giving us problems. I always wanted to fool around with Ubuntu/Linux and finally found the time. I set up a basic server with some help, and it finally came time to transfer the files. Turns out the one disk is dead, can't get any info off of it.
The second one is working, but it will not let me access it. I tried to use the hard drive in the DNS-323 networked, but it won't let me access it (permission denied). Used the DNS-323 ftp server, and with that I was able to access it and see the files but I couldn't download anything. Unplugged the hard drive and plugged it into my Windows machine (used a program that will read ext2/ext3 formatted disks) and it would not let me in. Finally I plugged it into my Ubuntu machine and did a fdisk -l, and it told me the partition was

[SOLVED] Recovering data from a repartitioned Windows drive
location: ubuntuforums.com - date: November 5, 2007
I've Googled around and haven't been able to find a straight answer to this exact question.
A friend (Windows user) accidentally repartitioned her external hard drive. Right after doing that, she tried to use some recovery program (she doesn't remember which one) to get some of the files back. She was able to get pictures back but not music or Word docs. She hasn't touched the drive since.
I thought I might give recovery a try. A few questions, though: I know testdisk can recovery lost partition tables or deleted partitions, but is it useful for newly created partitions over old partitions?Would foremost be a good choice for getting these Word docs back?How likely is it that these Word docs and music are recoverable? Doesn't a repartitioning reformat the drive? I guess since she was able to get pictures back, the files weren't fully deleted, but I haven't done a lot of data recovery so I don't know.Would Knoppix or Ubuntu work better for this? Or does it matter?
