Error Mounting Mount /dev/sdf1 Is Not A Valid Block Device
2010, 11:39 AMHello, Ubuntu refuses to recognize/mount my external harddisk (Western Digital 500GB). This happened after installing Ubuntu 10.04lucid (before I was on 9.10 and everything went well). As a linux-newbie, I searched forums and tried all kinds of things is not a valid block device mount cifs with gparted, parted magic boot-CD, system rescue CD, and so on ... I formatted /dev/sdb1 is not a block device the external harddisk to FAT-32 (I want to keep dual-booting with Windows Vista). No matter what I try: either he doesn't regognize the is not a block special device disk or he refuses to mount it (like now: error message after logging in + Disk Utility recognizes but refuses to mount it). Disk Utility says: Error mounting: mount: /dev/sdf1 is not a valid block device Any mount is not a block device ideas (please include code/specifics for this linux-dummy) would be greatly appreciated.

Thx for replying. Here is what he says: pepe@pepe-desktop:~$ sudo fsck.vfat -y -v /dev/sdf1 dosfsck 3.0.7 (24 Dec 2009) dosfsck 3.0.7, 24 Dec 2009, FAT32, LFN open: No such device or address pepe@pepe-desktop:~$ Does this mean he actually recognizes the disk but refuses to mount/open it? About NTFS: I'm going to try it but from what I've read I thought it was going to give problems for Linux/Ubuntu to recognize/read/write the disk... Thx again for ur time. peter mikewhateverApril 6th, 2010, 05:00 PMNo, Ubuntu, and other modern Linux distros, have no problem with ntfs. I don't think the command did anything because /dev/sdf1 doesn't seem to exist. Try running sudo fdisk -l to find out the device name. dino99April 6th, 2010, 05:44 PMgoto system --admin --mountManager and check that you have rights to mount a device (admin by default, so change with user) peter_kintApril 6th, 2010, 05:47 PMNo, Ubuntu, and other modern Linux distros, has no problem with ntfs. I don't think the command did anything because /dev/sdf1 doesn't seem to exist. Try running sudo fdisk -l to find out the device name. Here is the output. The external HD doesn't seem to be listed... pepe@pepe-desktop:~$ sudo fdisk -l Disk /dev/sda: 320.1 GB, 320072933376 bytes 255 heads, 63 sectors/track, 38913 cylinders Units = cylinders of 16065 *
various Linux kernels and distributions. Typing that string into your search engine of choice will yield a lot of results and possible solutions. The first recommendation was to check to make sure the usb-storage and uhci modules are loaded (# lsmod); and they were in my case. I even unloaded them and reloaded them (# modprobe -r module_name, # modprobe module_name) and still got the error. The next most common recommendation that I saw was this:# mount -t vfat /dev/sda1 /mnt/usbdevnameThat didn't work for me this time. However, I did find a suggestion that did work. Plug in the device and then type:# fdisk -l(That's a lowercase "L") Now https://ubuntuforums.org/archive/index.php/t-1448056.html this isn't going to erase your hard drive or the data on your device. It will, however, tell you what disk partitions you have on your system, whether they are mounted or not.So, if you get the "/dev/sda1 is not a valid block device" error, plug the device in and type "fdisk -l." Then you should see something similar to this, along with information about your hard drive partitions, which I did not copy here:Disk /dev/sdb: 1027 http://www.brianwsnyder.com/blog/2006/10/devsda1-is-not-valid-block-device.html MB, 1027604480 bytes16 heads, 32 sectors/track, 3920 cylindersUnits = cylinders of 512 * 512 = 262144 bytesDevice Boot Start End Blocks Id System/dev/sdb1 * 1 3920 1003504 e W95 FAT16 (LBA)Then all you do, based on this example, is edit /etc/fstab and change /dev/sda1 to /dev/sdb1 and keep the options the same across the rest of that line. Then just mount like normally would:# mount /mnt/usbdeviceThat did the trick for me. But, try this at your own risk as I can't offer any guarantees! posted by bwsnyder @ 10:19 1 comments 1 Comments: At 12:05, Grzegorz said... THX! bwsnyder.I thougth, that I had camera on sda1, but I type fdisk -l and system show me, my camera on sdb1 :)Now is OK.Thank you for help.

( sdb becomes sdX because of how the usbs are enumerated) Open a terminal and play with: lsblk blkid If you are still unsure, then try dmesg | more and read the system log, at one point you should see something similar to: 150289.144120] scsi 7:0:0:0: Dir
