The ExFAT File System Driver service is a file system driver. If the ExFAT File System Driver fails to load or initialize, the error is recorded into the Event Log. Windows 7 startup should proceed, but a message box is displayed informing you that the exfat service has failed to start.
There are a number of reasons why you could be encountering issues with exfat.sys. Most of the issues concerning SYS files involve Blue Screen of Death (BSOD) errors. These types of exfat.sys errors can be cause by hardware problems, outdated firmware, corrupt drivers, or other software-related (eg. Microsoft Office Access 2010 update) issues. Some of these errors include:
If none of the previous three troubleshooting steps have resolved your issue, you can try a more aggressive approach (Note: Not recommended for amateur PC users) by downloading and replacing your appropriate exfat.sys file version. We maintain a comprehensive database of 100% malware-free exfat.sys files for every applicable version of Microsoft Office Access 2010. Please follow the steps below to download and properly replace you file:
CAUTION : We strongly advise against downloading and copying exfat.sys to your appropriate Windows system directory. Microsoft typically does not release Microsoft Office Access 2010 SYS files for download because they are bundled together inside of a software installer. The installer's task is to ensure that all correct verifications have been made before installing and placing exfat.sys and all other SYS files for Microsoft Office Access 2010. An incorrectly installed SYS file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
ExFAT File System Driver is a file system driver. In Windows 7 it won't be started if the user doesn't start it. If ExFAT File System Driver fails to start, Windows 7 attempts to write the failure details into Event Log. Then Windows 7 startup should proceed and the user should be notified that the exfat service is not running because of the error.
I tried using an external usb hard drive as my download directory for torrents, kept corrupting the files and often straight up crashing the computer. Testing showed the drive was plenty fast, so I was like what the hell As it turns out the whole reason was that drive was formatted exfat. After reformatting to NTFS it works fine. Wish I had realized that a year ago. 153554b96e
