I want to mount my usb drive (kindle vfat32). When I domount -t auto /dev/sdf1 /mnt/usbI getmount: unknown filesystem type 'vfat'I checked if the drive is recognized with sudo fdisk -l and the recognized filesystem is W95 FAT32my kernel is 3.2.0-4-686-pae. I checked the recognized filesystem with cat  /proc/filesystems and vfat is not there. dosfstools is installedwhat should I do?I am using the kernel released in the minimal netbook installation of debian. If I run modprobe vfat as root I get the following:libkmod: ERROR ../libkmod/libkmod-module.c:174 kmod_module_parse_depline: ctx=0xb8556008 path=/lib/modules/3.2.0-4-686-pae/kernel/fs/fat/fat.ko error=No such file or directorylibkmod: ERROR ../libkmod/libkmod-module.c:174 kmod_module_parse_depline: ctx=0xb8556008 path=/lib/modules/3.2.0-4-686-pae/kernel/fs/fat/fat.ko error=No such file or directoryERROR: could not insert 'vfat': Unknown symbol in module, or unknown parameter (see dmesg)When I cat /proc/modules I get:dm_mod 57362 0 - Live 0xfcb45000ip6table_filter 12492 1 - Live 0xf847a000ip6_tables 17185 1 ip6table_filter, Live 0xf8564000snd_hda_codec_realtek 142274 1 - Live 0xf86a3000ppdev 12651 0 - Live 0xf8408000binfmt_misc 12813 1 - Live 0xf8454000lp 12797 0 - Live 0xf846d000nfsd 173890 0 - Live 0xf8711000nfs 265921 0 - Live 0xf86cf000nfs_acl 12463 2 nfsd,nfs, Live 0xf8437000auth_rpcgss 32143 2 nfsd,nfs, Live 0xf8501000fscache 31978 1 nfs, Live 0xf8494000lockd 57277 2 nfsd,nfs, Live 0xf850a000sunrpc 143904 6 nfsd,nfs,nfs_acl,auth_rpcgss,lockd, Live 0xf852e000iptable_filter 12488 1 - Live 0xf8403000ip_tables 17079 1 iptable_filter, Live 0xf8421000x_tables 18158 4 ip6table_filter,ip6_tables,iptable_filter,ip_tables, Live 0xf8414000usbhid 31554 0 - Live 0xf84cf000hid 60152 1 usbhid, Live 0xf84e5000nouveau 526808 3 - Live 0xf856d000mxm_wmi 12467 1 nouveau, Live 0xf8385000video 17459 1 nouveau, Live 0xf841b000ttm 47786 1 nouveau, Live 0xf842a000drm_kms_helper 22738 1 nouveau, Live 0xf840d000drm 146387 5 nouveau,ttm,drm_kms_helper, Live 0xf84aa000snd_hda_intel 21786 6 - Live 0xf8473000snd_hda_codec 63477 2 snd_hda_codec_realtek,snd_hda_intel, Live 0xf8443000snd_hwdep 12943 1 snd_hda_codec, Live 0xf835b000snd_pcm 53461 3 snd_hda_intel,snd_hda_codec, Live 0xf8459000snd_page_alloc 12867 2 snd_hda_intel,snd_pcm, Live 0xf843e000snd_seq 39512 0 - Live 0xf8394000snd_seq_device 13016 1 snd_seq, Live 0xf82e3000snd_timer 22356 2 snd_pcm,snd_seq, Live 0xf8363000power_supply 13283 1 nouveau, Live 0xf8356000snd 42722 19 snd_hda_codec_realtek,snd_hda_intel,snd_hda_codec,snd_hwdep,snd_pcm,snd_seq,snd_seq_device,snd_timer, Live 0xf834a000i2c_nforce2 12520 0 - Live 0xf8345000i2c_algo_bit 12713 1 nouveau, Live 0xf83fe000i2c_core 19116 5 nouveau,drm_kms_helper,drm,i2c_nforce2,i2c_algo_bit, Live 0xf8378000soundcore 12921 1 snd, Live 0xf82d0000evdev 17225 8 - Live 0xf82f7000acpi_cpufreq 12807 0 - Live 0xf82e8000mperf 12421 1 acpi_cpufreq, Live 0xf82de000processor 27565 1 acpi_cpufreq, Live 0xf84a2000thermal_sys 17752 2 video,processor, Live 0xf8372000parport_pc 22036 0 - Live 0xf83a9000parport 31254 3 ppdev,lp,parport_pc, Live 0xf83a0000coretemp 12770 0 - Live 0xf838f000container 12525 0 - Live 0xf838a000button 12817 1 nouveau, Live 0xf8380000wmi 13051 2 nouveau,mxm_wmi, Live 0xf836d000pcspkr 12515 0 - Live 0xf82fe000loop 17810 0 - Live 0xf82d8000autofs4 22784 2 - Live 0xf82f0000ext4 306996 3 - Live 0xf83b2000crc16 12327 1 ext4, Live 0xf82be000jbd2 52330 1 ext4, Live 0xf82b0000mbcache 12938 1 ext4, Live 0xf8239000usb_storage 35142 0 - Live 0xf82c6000sg 21476 0 - Live 0xf8264000sr_mod 17468 0 - Live 0xf82aa000sd_mod 35425 5 - Live 0xf8295000cdrom 34813 1 sr_mod, Live 0xf82a0000crc_t10dif 12332 1 sd_mod, Live 0xf8234000ata_generic 12439 0 - Live 0xf822f000ahci 24917 4 - Live 0xf828d000libahci 18308 1 ahci, Live 0xf8242000ohci_hcd 22059 0 - Live 0xf826c000r8169 41802 0 - Live 0xf8281000mii 12595 1 r8169, Live 0xf821f000libata 125014 3 ata_generic,ahci,libahci, Live 0xf8325000ehci_hcd 35509 0 - Live 0xf8273000scsi_mod 135037 5 usb_storage,sg,sr_mod,sd_mod,libata, Live 0xf8303000usbcore 104555 5 usbhid,usb_storage,ohci_hcd,ehci_hcd, Live 0xf8249000usb_common 12338 1 usbcore, Live 0xf8215000
vfat not recognized in debian
debian;filesystems;mount;vfat;fat32
mount use libblkid to guess the filesystem from the device you're trying to mount, and you can see that it work from the error message it give:mount: unknown filesystem type 'vfat'but the weird thing here is that if the required filesystem is in a module that isn't yet loaded, mount try to auto-load the module using modprobe.So my only guess so far is that something is wrong with your kernel modules:/lib/modules/3.2.0-4-686-pae/kernel/fs/fat/vfat.ko/lib/modules/3.2.0-4-686-pae/kernel/fs/fat/fat.koeditor for some reason mount fail to execute modprobe.
