Hi @justforlxz
The issue persist:

I have unmounted and remount the drive shown below:

FYI, FUSE exfat should be considered deprecated as of now [1]. It has multiple known issues resulting in system not responsible, file system corruption, etc.

The issue doesn't look like related to dde-file-manager anyway as it blocked at mounting the disc.

@felixonmars the deepin repo does not have linux kernel 5.7+ version the latest kernel is linux kernel 5.4lts.
Also when the kernel 5.7+ reaches the repo does this means that exfat FUSE (exfat utils packages) can be removed since it is deprecated, so that it does not conflict with the kernel exfat module?

20.2 update have kernel 5.10, try upgrade?

[johnnyjacq16]

@felixonmars @justforlxz I am still experiencing the same problems after upgrading to deepin version 20.2 with kernel version 5.10. How can this problem be resolved? The hard drive has no issues when using a Apple Macbook Air and other linux distro like Debian so I know the hard drive is not at fault, the hard drive is also new from the factory.

@felixonmars @justforlxz The above issue still persist, any help would be greatly be appreciated.

@felixonmars @justforlxz The above issue still persist, any help would be greatly be appreciated.

I will contact the kernel developers to locate the problem.

Does this still occurs on the most recent release of deepin (currently v20.5)?
