The longer you wait, the higher the chance that the data will be permanently overwritten. That is because Recuva can only recover a deleted file if new data has not yet been written to the part of the disk where the deleted file was stored. A paid premium version is also available.įor best results, you should use Recuva (and most data recovery tools) as quickly as possible after accidentally deleting a file. Recuva is a free data recovery software that parses your file system in an attempt to recover files that you have deleted. It is sometimes possible to find the data again in order to recover the file. It is simply “forgotten” by the file system. You may not realize that when you delete a file, the data is not actually removed from disk. Several free data recovery software can help you to restore data even from disks that are damaged, or after you have erased data from your file system. For example, you may have a disk drive that begins to fail and contains data that is not backed up, or you may accidentally delete files that have not yet been written to a backup location.įortunately, it is sometimes possible to recover data in situations like this. In the real world, however, you may sometimes experience data loss without having a data backup in place. In a perfect world, you would have an automated data backup and recovery solution in place for all of your data so that you never need to worry about losing data. Shall I just buy a bigger hard drive and attempt the dd route? I've read that this can mess with LVM setups and there's the added risk of working on two unmounted drives at once with a low-level tool.This article provides an overview of free data recovery tools and explains what each one can do to help you recover data after a data loss. I could log in with my existing creds, but the network was kaput, I couldn't startX (desktop GUI) and there were also a few (a lot) of error messages pertaining to iptables. The boot did complete but there were lots of red 'FAILS'. I then rebooted and it went through the familiar start-up routine only to not find a host of files in proc, usr, lib, var etc. I then disconnected my original source drive again, booted from the liveCD again, changed back the boot partition label from /bootnew to /boot using e2label and then renamed the VolGroup back to VolGroup00. I could then boot with both drives in.Īfter mounting the new drive (via its VolGroup001 alias) into /newhd, I rsync-ed over everything I could to the new drive, using -avr switches and backslashes. I then changed the VolGroup name using lvm vgrename from VolGroup00 to VolGroup001. I then booted into rescue mode from the same CD, and, to avoid a conflicting label, changed the /boot partition's label using e2label to /bootnew. I had the idea of doing a fresh install of CentOS (from the original disk) on the new drive so the partitions and LVM were all set up correctly (after disconnecting my source drive to prevent painful mistakes). Thanks for your responses so far - it's much appreciated and makes me feel a little more confident when I can double-check things here. I'm also planning to rebuild the whole TTS system on Debian as the existing CentOS system still has PHP4 etc.įor now though, I'd really like to just shift everything over to a new drive.Īs this is my first post, please feel free to lay any house rules on me that I might've overlooked I've been hovering around StackOverflow for a while now but have only just signed up. The server itself, although not strictly a production environment, has a very specific installation of Festival, LAME and ffMpeg and provides the back-end for a Text-to-Speech jQuery plugin that I've built over the last 2 years. No joy here either as I hadn't chosen LVM when partitioning the destination drive and it wouldn't boot.Īs you can probably tell, I'm out of my depth here and a panic-invoking mixture of caution and frustration has prompted me to sign up here. My most recent attempt involved using a Debian CD to format the new drive and then rsync-ing everything over and editing the new drive's grub and fstab to reflect the changes. dd failed after about 2 hours, as, although the drives appeared to be identical on the surface (ATA Seagate Barracudas, Thai not Chinese), the destination drive is slightly smaller. I've spent many hours reading upon dd, dd_rescue, rsync, clonezilla and LVM mirroring yet the sheer number of options and nightmarish accounts has left me frozen - unable to make an informed decision as to how to start. Basically, I want to clone this drive to a similar sized one (80 Gig). I've been running a BlueQuartz CentOS 4 system ( distro) for a few years now and although the hard drive (Deskstar) has always been a bit noisy, on a few recent occasions I've heard it having trouble spinning up.
