General Data Recovery

  • Any file stored on our Novell servers is backed up every 2 hours and you can revert to older versions at any time. See below.
  • Outlook attachments are stored in a temp folder that is cleared out frequently. So if you open a Word document from an email attachment and make changes, you MUST choose "Save As" to save the document elsewhere. Documents saved in the Outlook temp folder are very likely unrecoverable.
  • Recuva - basic Windows file recovery. Can restore pictures deleted from a camera and so forth.
  • See this Lifehacker article for suggestions and instructions on other useful software.
  • For recovering data from a damaged hard disk, see below.
  • Professional help is available for severely damaged disks if other options do not work.

Recovering Files From Novell Servers

  • Using the Novell Client (Windows only): Right-click on the red "N" in the system tray (next to the time/clock), select "Netware Utilities" => Salvage. Then navigate to the folder you want to salvage files from, and click OK.
  • Using the NetStorage webpage (Mac and Windows): Navigate to http://go.middlebury.edu/files then login, navigate to the folder where the deleted/lost file was last seen. From the "View" menu select "Show Deleted Files".

Recovering Deleted E-mail Messages

  • Outlook configured to use Exchange (Windows only): Open "Deleted Items" folder => Tools menu => "Recover Deleted Items"
  • Outlook Web Access with Internet Explorer 6 or 7 (Windows only): there

Repairing Corrupt Word Documents

  • Word => File => Open => Open and Repair
  • Word => File => Open => Recover text from any file

Getting the Music from your iPod

It's possible to copy music from an iPod to the a computer: see this article

Damaged Disks

  • For damaged CDs / DVDs, Use the disk repair unit that LIS has. Helpdesk can make a ticket for media services, who has access to the repair unit.
  • DVD repair tool
  • Use DITTO, a command-line tool on Macs, to copy data over directly from one location to another. See below.
  • With really serious cases, try dd, ddrescue, or dd_rhelp in Linux. These are command-line tools but very powerful; they copy any data they can read byte-for-byte. ddrescue also saves a logfile of errors so you can run it a second time on the same CD, hard drive, or floppy disk and it will bypass the areas which have already been successfully recovered.

Using DITTO to recover files

Macs come with a built-in command line program that can be used for data recovery. Macs tend to be better than Windows at reading dead PC hard disks.

  • Start up a healthy Mac.
  • Connect the dead hard disk to this Mac.
  • Open Applications => Utilities => Terminal
  • Enter this in the Terminal window:
  • Where [SOURCE] should be replaced with the folder that you'd like to recovery/copy, and [DESTINATION] is a healthy hard disk where you'd like the recovered files to go. Note that you can type in:
ditto -V 
  • then drag the source folder to the Terminal window, and it will fill out the path to it correctly. You can repeat the same for the destination folder.
