The New School offers Disk Utilities Stations to repair and recover data files on disks. Find out more information on how to use these stations.

How do I make simple repairs to a disk?

To make simple repairs to a disk, follow these instructions:

Windows PC:

  1. Double Click on 'My Computer' to view all available disks and drives.

  2. Right click on your disk and use the drop down menu to navigate to 'Properties,' and choose the 'Tools' tab.

  3. Run 'Error Checking.' Make sure 'Automatically fix file system errors' and 'Scan for and attempt recovery of bad sectors' are checked. The files that are corrupt or in bad sectors already may not be usable but other files should work.


  1. Remove your disk and bring it to a Disk Utilities Station.

What are the Disk Utilities Stations and what do they do?

Disk Utilities stations are located near the Arnhold Hall 8th floor reception desk. These stations have software applications that help recover and repair problematic data files. When you have a Disk or portable Hard Drive that will not mount or is reporting damage, error or virus, bring it to a Disk Utilities station. It is important to note the Disk Utilities station is a Mac, which will handle cross-platform formatted and Mac formatted disks. If you have a Windows formatted disk, refer to the information in the Q&A above.

What Disk Utilities are available?

The following disk utilities are available in the labs:

  • Disk First Aid: Scans Mac-formatted disks only for minor errors and repairs them.

  • DiskWarrior: Scans for major errors and fixes/rebuilds the directories on your disk.

When should I use Disk First Aid versus Diskwarrior?

Try Disk First Aid first to repair a Mac-formatted disk. If it reports: 'Scan complete. Problems were found, but Disk First Aid cannot repair them', try DiskWarrior.

Use DiskWarrior if the disk is: not mounting (not appearing on the desktop when the computer is started); missing files or folders; or crashes when its files are used. DiskWarrior rebuilds your disk directory using data recovered from the original directory, thereby recovering files and folders that were lost.

What else can I do if Disk Utilities do not work?

You may want to try an outside data recovery service. However, if you've tried to scan and repair a number of times, your files likely are not recoverable. You can reformat to continue using the drive, but unfortunately, the data on your disk will be lost. The disk may also no longer be reliable and should then not be used to store files.

How do I get rid of a virus on my Disk?

At any station, Mac or Windows PC, run Symantec Endpoint.
