픽셀유동화를 누르면 "디스크 오류로 인하여 픽셀유동화 명령을 완료할 수 없습니다" 라고 뜨는데 해결 어떻게하나요?

​@Gyeong Is everything okay, or does it just seem that way?

Try to reset the Photoshop preferences:  https://helpx.adobe.com/ie/photoshop/using/preferences.html#Manually

If this doesn’t help, disable the option to "Use Graphics Procesor" from Photoshop by going to Preferences, then Performance. Once done, quit & relaunch Photoshop to check if that helps.

If it helps, you can check out the steps suggested here:  https://helpx.adobe.com/photoshop/kb/troubleshoot-gpu-graphics-card.html

If this also doesn’t help we need more information about your system. Please provide a copy of your 'System Info'. This can be get from the Photoshop menu item Help > System Info. There's a copy button in the System Info dialog. Press this button and paste the info into a text file and attach it to your next forum post.
