Ubuntu :: NHD / NAS Stopped Working - TestDisk Utility?
Jan 18, 2011
My NHD/NAS stopped working. Hoping it was a problem with the network card I pulled the hard drive out of the NHD case and mounted it in an external case. Windows 7 won't mount it, neither will XP, neither will a Mac. The drive shows up in the device manager but won't mount. It sounds fine spinning. Quiet and no different than before. The NHD was a 250GB Iomega black series. The actual drive inside is a Western Digital. I've been planning on trying Ubuntu for a while on an older laptop that really slowed down with XP SP3. Loaded ubuntu up - all went very smoothly. I'm quickly becoming a huge fan of the OS. I plugged in the drive on my new Ubuntu system and it mounted! The drive shows up as 3 drives which I'm assuming are partitions. I can actually access the middle 66 MB drive. It contains what I suspect is the Linux operating system for the NHD.
If I try to access the other two I get a pop-up per:
For the 66 mb I can't access - "Error mounting" mount /dev/sdc2: can't read superblock"
For the 250 gb I can't access - "Error mounting" mount /dev/sdc4: can't read superblock"
I then tried to run the testdisk utility on the 250 gb drive both using "sudo testdisk /dev/sdc4" and just "sudo testdisk". I've also tried NONE and the INTEL partition. Based on my earlier post and playing around with options I think running it with "sudo testdisk" and INTEL might be the way to go. See the screen shots for the errors and sequence of events. I don't know what to do next - which seems to be something to do with testdisk thinking my drive is a heck of a lot bigger than it is. If testdisk can't fix it - I really need this drive recovered. I had a 2nd drive ready to back up this 250 GB NHD. Never did it. That is a mistake I'll only make once!

I had a tri boot of Win 7 /XP and Mint...I was using EasyBCD 2.0 as a boot manager...I booted Mint by configuring the NeoGrub option in Easy BCD..I wanted to uninstall Win 7 and so what I did was the following
1. Edited BCD bootloader settings ...Marked XP as my default and deleted Win 7 entry...
2. Logged out and wiped my Win 7 partition
With my fingers crossed , i rebooted but Easy BCD booted flawlessly with 2 choices XP and Mint(GRUB)...As Easy BCD is not meant for XP, I thought of restoring original NTLDR of XP so that things would be in place and thinking that this cud avoid problems of detection by other Linux OS I deleted manually the Easy BCD menu.lst file and NeoGrub.mbr in my root...That was it , after I rebooted, I got boot screen of EasyBCD but whichever option I select,I got an error message that address not Valid-NTLDR not found or something like that I booted my XP live CD and like many times before ran
1.Fixmbr
2.Fixboot
3.bootcfg /rebuild
After that , now when I reboot , I am getting "Invalid Partition Table" On booting from a linux CD , I can see the files are in place..I have to get boot sector and partition table fixed...

I was having trouble creating a USB Startup Disk in Ubuntu and used the command:
sudo dd if=/dev/zero of=/dev/sdb bs=1M count=1
This was a mistake as my USB flash drive was on /dev/sdc. If I am understanding this correctly, the command above deleted the MBR and the partition table. This disk had a single "/storage" partition on it. I googled a solution and found that the "testdisk" program seems to be the most popular solution for things like this. I ran it, selected an "Intel/PC partition" type, set the partition to a non-bootable primary Linux partition, wrote it, and rebooted.
Whenever I run:
sudo mount -t ext3 /dev/sdb1 /storage
I get:
mount: wrong fs type, bad option, bad superblock on /dev/sdb1, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so
Dmesg shows the following:
[20246.273941] EXT3-fs error (device sdb1): ext3_check_descriptors: Block bitmap for group 1 not in group (block 0)!
[20246.279376] EXT3-fs: group descriptors corrupted!
When I run:
sudo fdisk -l /dev/sdb
I get:
Disk /dev/sdb: 400.1 GB, 400088457216 bytes
255 heads, 63 sectors/track, 48641 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

I cannot get the Disk Utility to launch, when I click the icon the cursor rotates and stops but nothing happens.
I uninstalled and reinstalled the Disk Utility, still not working.
I have three HDDs and many partitions. I multi boot Linux, Win 7 and Win XP.
All OS's boot cleanly using EasyBCD boot loader.
It did not work in 10.04 or 10.10.

I just did a clean install of Ubuntu 11.04 yesterday on my laptop. My laptop has three partitions. One for Win 7, one for Ubuntu, and another for data. The data partition is formatted NTFS and I'd like to have it mounted on startup. I had done this before using NTFS Configuration Utility and it worked great. Unfortunetly after installing Natty it seems to no longer work. Whenever I open the program from the app drawer it asks for my sudo p-word and then nothing happens. Nothing pops up... If i try to run it from terminal using
gksudo ntfs-config
The same thing happens but I do get the below text in term

When originally installing 11.04 I had problems getting my Ralink 5390 wireless card to work.
Today my computer froze completely and I had to turn it off via the power switch. When I turned it back on, wireless was no longer recognized! My iPod can connect to the network just fine, so it must be an Ubuntu problem. There are no problems with my ethernet connection either.
I researched this and found several threads about blocking and unblocking wireless devices using the rfkill command. Well, unfortunately for me the rfkill command doesn't work. When I type sudo rfkill list or sudo rfkill unblock all, nothing happens; it just returns me to my bash prompt. I even tried uninstalling and reinstalling rfkill...nothing.

resubscribed to Rapidshare and in the past could easily download my friend's discussion papers using the file manager called DTA that integrates into Firefox. I have taken out a new subscription to RS and instead of getting the files I am receiving small html referer files. In theory this should be corrected by ticking a direct download setting on RS, but it is making no difference. I can manually download the files so I am certain the files are on RS in full form. I am also successfully auto logging into RS and this means the name and password are being handed over correctly

After I installed Windows XP on my leftover partition, I decided to reinstall grub2.
Now when I reboot grub throws me in the grub shell, if I then type configfile /grub/grub.cfg it starts grub like its supposed to. Tho I cant seem to be able to go straight to the grub menu and no to the shell.

Have just started to use look at crontab. I could use Scheduled Tasks as well as crontab -e in terminal.
I must have changed something because now Scheduled Tasks just seems to load then dropout. Loading a task through terminal is accepten (crontab -e) but doesn't work.

It was working fine. Now, when I boot the computer(9.10 32 bit), I get the message asking me about the certificate. But Pandora never seems to load. I tried to reinstall the AIR app, but it tells me that it is running. I can't find it though. If I try to open Pandora again, nothing ever happens

I got a call from a friend who did the distrubution upgrade from 9.04 to 9.10 and all was well for about 2 weeks and then his desktop icons disappeared. He kept running it that way and never looked for help until a couple of days ago he tried to plug in a card reader to get some pictures from his camera and nothing happened. that was when he discovered that he couldn't run Nautilus at all. I had him purge nautilus and reinstall it but then he couldn't even log in to Ubuntu. Very strange indeed. Anyone else experience this? After going over all the settings and finding them what they should be, I just installed 10.04 and all is well except that he lost a few photos.

I have been using Ubuntu for many years now and pressing ctrl + alt + d used to minimize all windows and show the desktop, but this stopped working with 10.10. I checked keyboard shortcuts but don't see a way to turn it back on there.

I was SSHd into my laptop which is right next to me, then it lost battery power and turned off. When I switch it on, I can't FTP, SSH into it and the Network Drive (Samba) won't work.

I have been using Ubuntu 10.10 for about a week now, I have had many, many problems, but usually figure them out by searching through this forum, except this time:I have an HP touchsmart tx2 1025dx laptop. When I installed it, everything worked great, sound, mouse, and even the touchscreen. Right now I noticed that when I press the button on by laptop which toggles the touchpad, it works but after it would freeze the menus, so that they would not drop down, I have confirmed this after many restarts. Now the touchpad has stopped working completely. Although if use the toggle button, it will still freeze by menus. It also somehow stops my keyboard from typing things into programs, like firefox, but still somehow the control-alt delete still lets me restart it.
My question is how can I reset the mouse settings/preferances to how they were when I installed? I found something a while back that was xorgconfig??? but it has since been taken out of ubuntu 10.10 (I read this somewhere, please correct me if I'm wrong.) I hope this is enough information for someone to point me in the right direction.Recap:Laptop Touchpad not workingWhen I press the toggle Touchpad button, messes up the menusUsing HP Touchsmart Tx2 1025dx LaptopLooking for a way to reset/restore sound preferences/settings or enable touchpad/ps: I was able to come here because the touchscreen is still working I ended up doing this:rm -rf .gnome .gnome2 .gconf .gconfd .metacitywhich reset ALL of my settings back to when I installed it, without deleting my programs or files.I found this here: http://linuxfud.wordpress.com/2007/0...re-installing/

I did a bunch of uninstalls and reinstalls lately, trying different distros. Now I'm back to Ubuntu but tab autocomplete in terminals doesn't work anymore. It is quite less convenient now to use the terminal. I tried changing interpreter to /bin/bash and it doesn't work. I use guake.

I just installed Xubuntu on my old ThinkPad T40, and everything worked flawlessly until last night when I rebooted, and the sound stopped working. I'd rebooted it several times before with no problems.

I can access synaptic via my unity 2D launch panel, from the apps menu and from system settings.But today I went to use it and it won't launch.I have tried to launch it with each of the above and each time to computer starts to do something and then stops. No freeze up, it just stops with the launch of synaptic.I uninstalled it via software centre and re-booted. Then via software center I re-installed it, but it still doesn't work.

I have a media center box running Ubuntu 9.10 x64 and XBMC. One day sound just stopped working on it. I did not install any updates around the time this happened. I have tried using a known working sound card. I verified the main volume is up and everything else in alsamixer looks OK. I have tried connecting known working headphones. Confirmed the kernel sees the hardware and loads to module for it. Confirmed several audio applications have no sound. I've confirmed it is set to use the correct sound card. I even booted into a live disk of the same version if Ubuntu and audio works fine there.
No errors are produced by any application, they act like they are playing audio just fine. The only entries in the logs about this I can find is below.

I did an internet upgrade last night and right around then I think I also got a little liquid around the touch-pad of my laptop and now the left click won't work in Ubuntu on either my touch-pad OR mouse so I am not sure if maybe the connection for the left click on the touch-pad is shorted causing it to stay "clicked" which somehow disables the left click on the mouse... On my windows xp partition(which I am using now) I am able to use the left click on the mouse but still not the touchpad... Anyway I am wondering if there is a way to disable to touchpad via console or some other way to get around this so I can back my important docs and files and then "mouse" it till I can get a new laptop.

I know 64 bit Flash has been a headache, but mine was working until yesterday. Symptoms began with it not working in Opera and Seamonkey. I checked the Adobe site and found what appears to be a later version, so I downloaded it, extracted it, then copied it to the relevant directories. That changed nothing at the time, but this morning it stopped working in Firefox as well.
