Hello together,

I have an external exFat formatted device.

I emerged exfat-utils and fuse-exfat.

When trying to mount this device, I get:

Code: Select all

Error mounting: mount: unknown filesystem type 'exfat'

Can someone help pls?

Best

try with -t vfat? mount -t vfat.

if that doesn't work, you need to recompile your kernel with exfat support. see filesystems options.

EDIT: or emerge sys-fs/exfat-utils sys-fs/fuse-exfat ?

Hi axl,

thanks for fast reply.

recompile your kernel with exfat support

Kernel supports vfat.

try with -t vfat? mount -t vfat.

I tried, result:

Code: Select all

mount: wrong fs type, bad option, bad superblock on 192.168.1.5:/home/shared, missing codepage or helper program, or other error (for several filesystems (e.g. nfs, cifs) you might need a /sbin/mount.<type> helper program)  
In some cases useful info is found in syslog - try dmesg | tail or so.

dmesg output:

Code: Select all

FAT-fs (sdc1): bogus number of reserved sectors
FAT-fs (sdc1): Can't find a valid FAT filesystem

Do you think something might be wrong with formation?

no. it was my bad. didn't know exfat isn't support natively in kernel. see the later edit. most likely emerge sys-fs/exfat-utils or sys-fs/fuse-exfat. not sure which.

Thanks everyone.

Somehow ... I completely missed emerging fuse-exfat (I was so sure) ...

Now it's working fine ...

Thanks everyone
