I own a secondary SATA disk I used without problems. In the last days I updated to 8.1 and after that I was not able to read the disk. The fdisk -l command has the output:

The disk is mounted on:

When i access to the disk, i always have the error:

In the dmesg there is no particular message.
Since I installed 11.3 I have noticed the /srv and /local mount points are empty! I also can no longer see my hard drives that have no mount points. I couldn't mount any hot plug media either but now have that fixed. I won't go into the mess I have with my video card and getting the x server started....
I did have Xampp installed to /srv/www but don't even know where it is now!

I had no problems with this in 11.1 until a month ago when I updated and it seemed to keep losing the permissions for these drives as once I accessed them via Dolphin they would be accessible. Now they are not even visible in a file manager!
within the last 24 hours I have lost a reiser formatted disk. It is not visible not with df or fdisk.Which tools do you normally use in a situation like that.

I have a 2 TB disk in an external SATA dock, formatted with a single ext3 (Linux) partition, which doesn't show up in the Windows 7 Computer Management->Disk Management utility, even as a raw/blank disk. I've verified that there's nothing wrong with the disk by connecting it to my Linux machine and mounting it, and I've verified that the dock is functioning properly by connecting a different FAT32-formatted disk, which mounts flawlessly as expected.I realize that I can't actually read the ext3 partition without additional software (e.g., Ext3IFS), but why doesn't the disk show up at all? Is there some sort of stupid anti-Linux filter built in? Is there any way to force Windows to recognize the disk, so that I can at the very least use direct block access with it?
Background: I want to clone an identical 2 TB disk onto this one. Due to my hardware layout, it's much easier to have the source disk attached to one machine and the destination disk connected to another, and do the clone over the network (the network is not a bottleneck with switched gigabit ethernet), than it is to hook them both up to one machine.(1) I did this once before when both machines were running Linux, but I've since upgraded the destination machine and decided to switch back to Windows for regular desktop use. I've got Cygwin installed, and have verified that the same basic method (dd + nc) will work, but I can't do anything if Windows doesn't even consider the destination disk to exist.I only have one eSATA port on each machine. Opening them up just to do this clone is a rather large annoyance. Also, since this is my backup disk, I'd like to eventually automate the cloning from the active disk to another one that I regularly swap with a third disk that I store off-site.
OS: Debian unstable 32bit, kernel 2.6.32-2, grub 1.98 from late january 2010 (only have working net-access from work now, so I am grabbing information from memory). EXT3 and EXT4 support is compiled into the kernel along with chipset/scsi/sata support (not as modules), and I have tested to boot ext3 with it before proceeding. Prereq: my old disk started to have too much S.M.A.R.T errors, so I bought another one, put in a USB cabinet, added swap and ext4 partition/filesystem to it, and copied over all data from the old system to the new that was mounted at /dest using the command "find ./ -xdev -print0 | cpio -paV0 /dest". Swiched disks, so I now have the ext4 disk sitting at /dev/sda (partitions: sda1 => ext4, sda2 => swap), and booted into rescue-mode from cdrom, using /dev/sda1 as root with a shell on. After doing this, I performed the following commands:
mount --bind /dev /dest/dev
chroot /dest
modified the /etc/default/grub to instruct the kernel to boot using ext4, ran grub-install --recheck /dev/sda
ran update-grub to modify /boot/grub/grub.cfg (which looks as it should) After doing this, grub finds my partition and mounts it. It however stalls with the message: "warning: unable to open an initial console" and does nothing after this point. I have no ramdisk, but my old kernel booted fine from ext3 (and still does if I copy it to a ext3 partition), and since the ext4 support is compiled into the kernel - should I really need a ramdisk?

S.M.A.R.T.tells me my primary fedora drive has lots of bad blocks,so I ordered a used identical drive from ebay.I want to do the very basic process of making a full backup of my existing drive - so as to replace it with a more or less identical replacement. Logically identical - not necewsarily sector to sector identical.im not literate in unix and its children - and seem to find a plethora of descriptinos of how to do what I want to do. which is
1. format the drive - what you may call low level format - ie op sys independent.
2. create a partition system compatible with my existing disk.
3. copy everything from my existing disk to the new disk.
4. put existing disk on the shelf as a backup and start to use new disk.
I have a Gigabyte GA-MA74GM-S2 motherboard with integrated graphics that shows up on lspci as an ATI Radeon 2100. I also bought a PCI-Express Nvidia graphics card so I could use the VDPAU feature on Linux (plays H.264 in hardware). The BIOS has three settings about which display to initialize first:
Integrated graphics
PCI graphics
PCI-Express graphics (PEG)
I set the BIOS on PEG, but
I cannot get anything, not even a splash screen or POST messages, to emerge from the PCI-Express graphics card. (I'm using a DVI connector; the card also has an HDMI output.)I cannot get the kernel lspci to see the graphics card; the only VGA controller it acknowledges is the integrated one.Running dmidecode acknowledges the existence of an x16 PCI Express slot, and it says
Current usage: Unknown
There is an additional BIOS setting called "Internal Graphics Mode" which is normally set to "Auto" which means it is supposed to prefer a PCI Express VGA card. I set it to "Disabled" which now means I'm getting no output at all. I will soon be learning how to do a BIOS reset!
Other information: The PCI-E card is a MSI N210-MD512H GeForce 210. This is a fanless card. Although there are no fans to see turning, the heat sink on the PCI-E card is definitely getting hot, so the card is getting some sort of power.It gets all its power from the PCI-E slot; there is no external power connector.The BIOS is an AMI Award BIOS.how can I make the PCI Express graphics card visible to Ubuntu?
I've been using Ubuntu 10.10 for just under a week. Recently, a partition called 'Data' has disappeared, and all my music and documents along with it. The folder is not to be seen in Places or on my desktop. My only way of finding it is to go to terminal. But when I try to open it there I get an error saying I don't have permission to read it. In Puppy Linux and SliTaz I can easily find the partition and read it. What should I do to bring it back in Ubuntu?

I had a dual boot (windows 7 + debian), both of them installed in my internal hard disk, with the GRUB in it. I have recently installed a second linux distro (mint), but I put it in an external hard disk. Now the GRUB allows me to boot any of the three operating systems, but I need the external disk to do it. It seems that after the mint installation the GRUB is now working from the external disk (if the external disk is not connected, the machine does not boot.) �Is there a way to change the location of the GRUB, to the internal hard disk of my laptop?

I have installed Ubuntu for a friend and find that on that installation Audio CD's are not automatically visible.
Data CD's appear fine and audio CDs are visible with some software (e.g. with RipperX) but they are not visible in the file system and cannot be played directly (e.g. with RythmBox).
With my installation of Ubuntu (also 10.4), as soon as I insert an audio-CD, I am prompted as to whether I want to open the CD with RythmBox. This does not happen with the other installation.
Does anyone have any tips here? Do audio-CD's demand that a certain package is installed for them to be visible/playable?
