Do not panic if you perceive a "scratch disk error" in Adobe Photoshop. This entire denotes is that you have attained or neared the maximum ability on your hard drive. When you open Photoshop and save or modify files, you must save the new data to the hard disk. If there is no more space on your drive you will perceive this error. There is a simple solution to this difficulty.

Instructions:

1.
Click on "OK" to close the "Scratch Disk" error dialog box.

2.
Open Windows Explorer (type in “explorer” then press enter in the "Run" box under the Start menu).

3.
Click on the "Search" tab on the Explorer toolbar. Click "All Files and Folders." On the next screen choose "Local Hard Drives" under the "Look in" box. Type "~PST" (without the quotations) to discover momentary Photoshop files. These may be what are taking up so much space on your hard drive. Delete any "PST" files that were not formed that day (or during your session).

4.
Return to the "Search" box in Windows Explorer (choose "All files and Folders" and "Local Hard Drives" again). This instance clicks the "What Size is It?" option. Choose the "Large (more than 1 MB)" radio box and then click "Search." This will locate all large files on your hard drive.

5.
Delete any extra large files (over 1 MB) from your hard drive to free space.

6.
Return to your Photoshop program. Click "Image" then "Image Size" on the main menu. Choose if you can pay for to reduce the resolution number. For a high resolution image, you can do 300 dpi but if you are only going to employ this for an online image you can set it as low as 72 dpi. Reducing the resolution will decrease the size of the file and free more space on your disk.

7.
Try to save the file now that you've made more room on the drive. This should decide the scratch disk error.
