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
Recovering Word Documents
Word or computer crashed before saving
There are multiple approaches here, and some scenarios where the document is probably unrecoverable.
- Working on a public machine, the computer crashes or shuts off; the document was not saved or was saved on the hard drive: Probably can't be recovered. DeepFreeze erases all changes made to a computer every time it is restarted.
- The document had been saved on Tigercat previously, but Word crashed before changes could be saved: A recovery file containing the changes made may be saved in the same folder as the document. Look in the folder for hidden files with a similar name.
- When Word crashed, it may have saved a log of changes on the computer. Open a new blank document in Word and then look in C:/ for a plain text file called 'Recovered.txt' or something similar.
- Word may detect that it crashed and that work was unsaved. On re-opening it will display a dialog asking if you want to try to recover the lost files.
Corrupt Word Documents
You can often recover the text from a document even when the document format is corrupt.
- 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
- Is the disk clicking? This is the most likely indicator of physical disk damage. Regular, punctuated clicks are the most dire signals.
- If there is absolutely no noise from the disk and no recognition of it, the disk might have an electrical failure. In this case there's little chance we can recover anything...
- OS won't start, or Windows system file missing or corrupt = possibly local disk damage. Other files may not be damaged; boot with a live CD and try to retrieve files.
- For Macs, try accessing the disk using Target Disk Mode.
- For Windows or Mac, start up a live Ubuntu CD and try accessing the disk. (If the disk is NTFS and Windows was not shut down properly, you will need to use command line to do this; consider using the BART CD instead.)
- 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.
CDs / DVDs only
- 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
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:
ditto -V [SOURCE] [DESTINATION]
- 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:
- 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.
