following problem. A friend phoned me in despair. Her Ubuntu didn't start any more - ASUS-Laptop switched on stops at a ramfs-prompt. I started Puppy-Linux from DVD-Drive. Worked fine. But puppy can't mount her /dev/sda1 partition either. At least you can see that the partition is still there. Fsck stops with an error. May be the initial problem is a sort of bad hardware by which bad bytes were written to the hard drive. Hard drive and/or memory could be replaced but not the data.
When the computer starts, you will read a flashing message about S.M.A.R.T and a few other things.I have two hard drives. There is a strange noise from the computer when I run it for more than 3 or 4 hours continuously. I firmly believe one of the hard drives is not working properly. I saw a message about a problem in S.M.A.R.T.It was a flashing message. I couldn't read it. I don't run any Windows on the computer. All are Linux. The default is Mandriva.
How do I read the flashing message you see at the start of a computer? I want to find out the damage one replace it with a new one.
I have recently gotten hold of a device that helps me plug my old ATA/IDE hard drive to my computer and view my old files that I wish to recover. I am using Ubuntu and the harddrive that I wish to retrieve the data from also has an Ubuntu install on it. The files I wish to recover are old .doc files, which I want to keep to remember my old writings.
The problem I have encountered arises when I wish to open some of the files. The icon for some of the files, which happen to be my best writings, has an X on the top right, indicating that I cannot view the contents. When I click on the files, the following error message pops up: "Access to /media/c885571b-a6e5-4a2d-937a-78af7050910/george/Courses/hist388/Passion.doc was denied."
Now, I am guessing that I need to be able to log in as superuser or something to be able to access these files, so I logged in my terminal as super user by following the instructions outlined on this page: [url]
I still did not have the sufficient access required to be able to open the files that I would like to retrieve.
I am trying to transfer files from a SATA hard drive with Windows Vista (Home Premium) installed on it. Some files I can easily copy over, others just say Access Denied.
I'm sure permissions is part of the issue, unofrtunately Windows is unable to boot at all (surpise surprise) so I can't adjust anything from within in. I know with XP drives I can easily copy and paste onto my Ubuntu machine. I'm using a SATA to USB converter that let's me plug it in and my desktop reads it like an external hard drive.
I've gone into the properties and under permissions it shows my account as having access to Create and delete files under folder access amd "---" under File access. My group and others show None and --- for Folder and File access. I can post a link to a screenshot tomorrow. I've tried to also select Read and Write for File access but it goes back to the dashes before I can apply it.
I am running 64 bit Ubuntu 9.10 and do not have the sharing aspect installed. Any questions please feel free to ask me.
OK, was trying to make a live-usb boot partition on my 1.5TB HD; in doing so clicked a 'wipe disk' button.
A second later I realised what I'd done, clicked cancel (frantically), tried to unmount the drive but was told 'volume busy'. In a panic, unplugged the drive. Unsurprisingly, the drive is now a mess.
I'd had 1 30G FAT32 partition (empty) at sdd1, 1 1.5TB ext4 partition with about 500G of data at sdd2. Now according to gparted I have an unrecognised filesystem type; according to the 'Disk Utility' I have an unmountable 1.5TB FAT32 drive.
I know NOTHING about data recovery. If it's just a case of running a couple of magic 'check & fix' programs then I should be OK, but anything else and I'll have to take it to more skilled friends.
I was trying to fix some hardware on my laptop and i ended up mucking the whole thing up. The HDD seems to fine though. I have it in a external HDD enclosure and it's plugged into my mothers desktop through usb.I'm trying to print some files I have, but my home directory on the external HDD is encrypted.
I learned a couple of days ago why you should do regular backups. Left my laptop working for the day in hot weather. When I came back it had crashed. On reboot it no longer booted up. I could still access the BIOS and boot from alternative media but not from the hard drive. The laptop tried to access the hard disk for a couple of minutes (hard drive light was blinking) and then failed. I made an ubuntu live usb stick and am currently working from there, trying to access my hard drive so I could image my data on another disk before sending the laptop for repairs. All my data is on that disk including my passwords and the password for this site conveniently so I had to register a new account to post this thread.
The laptop is IBM Thinkpad X41. The hard drive is accessed during when boot options are presented, again when the live cd boots up and determines the hardware available and also when manually probing for hard disks using the script below. The hard disk however does not show up in dev. If I could get so far to get it there, I could use dd_rescue to image it away. My hope lies in that the drive still spins up and is accessed producing error messages, however indicating that the system still knows it exists. Excerpt from dmesg concerning the drive:
I have an external USB hard drive that I need to recover some data from, but I see from fdisk -l that the partition uses LVM:
[root@localhost ~]# fdisk -l /dev/sdd Disk /dev/sdd: 160.0 GB, 160041885696 bytes 255 heads, 63 sectors/track, 19457 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes
I've followed various lvm tutorials all of which describe setting up lvm from fresh on empty disks. Unfortunately non mention how to 'install' new a drive that was previously set up with lvm. I have had a go anyway and may have now lost my data. Here's what I've ended up with (the partition in question is sdd1):
[root@localhost ~]# pvdisplay --- Physical volume --- PV Name /dev/sdd1 VG Name vg02
I've tried mounting with other fstypes, but all give the same error.
I have an Ubuntu server virtual machine running in vmware server on a Win2003 server host. A locked up machine forced a hard reset a couple of days ago and my VM seems to be damaged.At first VMware wouldn't start the VM, complaining of a locked file. I deleted 3 .lckdirectories and was able to start up the VM. I then get a GRUB menu with 6 options - booting any of them other than memtest results in a lone underscore cursor at the upper left corner.me in the right direction as far as the next thing I should try at this point? Unfortunately I had not yet set up a rigorous backup scheme, other than internal daily db/web backups that are stored inside the VM. I have a snapshot from 3 weeks ago but upon loading the snapshot I get the same cursor.
I have heard of a linux based data recovery for hard drives (corrupt) its bootable and once loaded and booted it will scan for drives and show there contents and let you pick and choose which ones you would like to back up/ save to a disk so you can wipe a drive and keep your info but I cannot remember the name of it.
My sister-in-law (SIL) has a Western Digital ShareSpace 4TB network access storage that was setup in a RAID 5 configuration (four 1TB hard drives). To make a long story short, a blinking red light on the device and a call to Tier 2 technical support, one of the guys mentioned using Fedora as a way to retrieve the data from the hard drives (seems like the hard drives are good but maybe the actual NAS device crapped out).
I will not have access to the hard drives till this weekend and of course Tier 2 technical support is closed on the weekends. I have almost no Linux knowledge but can follow instructions pretty darn well. I am looking to install Fedora 14 Desktop Edition 64 bit on my desktop sometime tonight or tomorrow. Once I have Fedora installed, how would I mount the hard drives and have Fedora read the RAID 5 array?
When my husband and I installed Open SuSE 11.2, we made the mistake of telling it to have my other 2 hard drives owned by root. So now, whenever I want to open my other 2 hard drives, I have to type in the root password. How can I change this?
I have a Centos 5.5 system with 2* 250 gig sata physical drives, sda and sdb. Each drive has a linux raid boot partition and a Linux raid LVM partition. Both pairs of partitions are set up with raid 1 mirroring. I want to add more data capacity - and I propose to add a second pair of physical drives - this time 1.5 terabyte drives presumably sdc and sdd. I assume I can just plug in the new hardware - reboot the system and set up the new partitions, raid arrays and LVMs on the live system. My first question:
1) Is there any danger - that adding these drives to arbitrary sata ports on the motherboard will cause the re-enumeration of the "sdx" series in such a way that the system will get confused about where to find the existing raid components and/or the boot or root file-systems? If anyone can point me to a tutorial on how the enumeration of the "sdx" sequence works and how the system finds the raid arrays and root file-system at boot time
2) I intend to use the majority of the new raid array as an LVM "Data Volume" to isolate "data" from "system" files for backup and maintenance purposes. Is there any merit in creating "alternate" boot partitions and "alternate" root file-systems on the new drives so that the system can be backed up there periodically? The intent here is to boot from the newer partition in the event of a corruption or other failure of the current boot or root file-system. If this is a good idea - how would the system know where to find the root file-system if the original one gets corrupted. i.e. At boot time - how does the system know what root file-system to use and where to find it?
3) If I create new LVM /raid partitions on the new drives - should the new LVM be part of the same "volgroup" - or would it be better to make it a separate "volgroup"? What are the issues to consider in making that decision?
I have 6 disks (partitions) combined into one lvm volgroup in my server. The server have been online for a year.
And today, suddenly it hangs. At first, I thought it's caused by network lag, because after a couple minutes the server is responsive again. But then I felt something very wrong. I can't access any file that stored on the lvm.
After some dmesg, fdisk -l and a peek at /etc/lvm/archive/*, I found that one of the partitions used for lvm volgroup is missing. Tried a reboot, and the suspected disk is undetected even in BIOS. Must be caused by bad block on the disk's sector zero or something. I think missing one pv makes the volgroup failed to initiate. So, no volgroup, no logical volume. And I can't access the files on it for sure.
Is there a way I can save/rescue data from other non-damaged disks? I have no luck finding similar situation (and solution) by searching on google.
Yesterday, my windows xp died and I can not do anything with that, but I would like to rescue my important files from hdd before format. I open ubuntu trial version from cd but i can not access my hdd. I find my hdd in system->administration->disk utility but I can not go anywhere from there.
When I solve this problem I would like to try ubuntu as my os but i am worried that some programs may not work on it . Like for example my bamboo tablet, fm2010, adobe ilustrator, autocad.
My laptop was damaged a couple of months ago. Just a short drop from the couch, but it was hard enough to make the HD inaccessible. I took it to a local, respected shop but they couldn't save any of the data and simply installed a new HD after consulting me.
I have the old drive and would still like to retrieve the data, if the price is right. What should I ask about when looking for another repair shop?
I've been using ubuntu about a year, so I have a fair amount of experience with it. Today I was trying to install ubuntu on my new laptop, which doesn't have an optical drive. I don't have a usb stick, so I attempted to partition my external hard drive. I stupidly clicked "erase disk" on startup disk creator and erased the entire drive instead of the partition. I want to get back the files I had on this external. I searched and managed to find that people had been successful with testdisk. when I choose to analyse, it only finds the partition I created for the live cd.
When I choose advanced, I can find my older partition (FAT32) but when I choose to undelete I get: Code: No file found, filesystem seems damaged.
When I choose boot I get: Code: Boot sector Bad Backup boot sector Bad Sectors are identical.
A valid FAT Boot sector must be present in order to access. Any data; even if the partition is not bootable. I searched but I couldn't find anyone receiving this error message or how to deal with it. So I tried using photorec. Photorec is recovering all of my documents currently but without the filenames and file structure, it's more or less worthless.
I've got 4 identical 1 TB drives and would like to use them in a software RAID configuration on my home server. I'm running Debian Linux using 'mdadm' utility to manage the software RAID. I don't know how much I've read is fact or dated or even false so I decided I would ask here to get help from people who know more about this than I do. This is essentially just a file server machine to store all my data so being that I've got four identical SATA hard drives, I was thinking about doing RAID level 5. I guess I'll start here and ask if that is the recommended level of RAID. I think RAID level 5 will be fine for my general server usage. My second issue is partitioning the four individual drives to get maximum performance / space from them. Basically just asking here how would you or you recommend I partition the drives? I was thinking about doing three seperate partitions per drive:
/dev/sda1 = 4 GB (swap)/dev/sda2 = 1 GB (/boot)/dev/sda3 = 995 GB (/)Now from that partition schema above, obviously all the types will be 'fd' for RAID and the partition for /boot is going to be bootable. My confusion is that I read Grub doesn't support booting from RAID 5 since Grub can't handle disk assembly. If /dev/sdx2 (sda2, sdb2, sdc2, sdd2) are partitioned for /boot (bootable), how would you guys configure this RAID to match up equally? I don't think I do a RAID level 1 on 4 identical partitions, right?
I haven't run into this with ubuntu before. I am trying to recover some files from a damaged hard drive and when I try to use the no change to computer option I get to a log in screen. But, I don't have a user name or a password at that point.
Caused by Used fdisk to delete the windows partition, in my dual boot. Then I could no longer log in to ubuntu, the partition table was some how courpt and I couldnt remount I then decided to use the windows partitioner from windows setup, as I thought it is so stupid, to reformat the partition where I had ubuntu. I wanted reinstall ubuntu, and I know that during the setup I could straighten out the mess I'd made.
Windows has now installed two 8mb one cylinder partitions on my HD. When I start the PC I get a !disk error occurred Press Crlt Alt Del to restart! This happens everytime. HD boot sequence is buggered, i guess.
I can boot from other devices. USB + CD. How when I use the windows disk to boot up I can see the 2 8mb partition, which it wont let me delete. How can I delete this via linux?
Also when I try to install ubuntu from the usb drive, it stalls just after the Preparing to install part. The next screen is when you set the partition table, swap drive etc. When I quit I get the following error !Process Glib WARNING getpuuid_r() failed due to unknown id!
The usb_liveCD does however mount my hard disk partitions and luckily I have managed to back everything up to an external.

i have recently setup and installed Ubuntu 9.04 on a virtulal drive usingVMWare 6.04, installed the desktop gui as well, I need to add other drives for data and loggng, which I did in the VMWare side. I can see the 2 drives in ubuntu, but can not access them, I get he unable to mount location when I try. How can resolve this please as I need these to virtual drives to be used as data drives.
I have a DVD that I want to recover. The problem is that it will not mount because it has a small scratch at the beginning of the first track. Is there any way to force mount the DVD and recover at least the unscratched part of the DVD?
So I've pulled two hard drives out of my busted windows xp system (dead mb) and I'm trying to get some data off of them. The drives are in raid 0, so my friend told me that I might be able to do something if I use linux. Some late night searching on the internet directed me to a few resources, one of which was this forum. I've tried 2 methods, neither of which have worked.
ubuntu@ubuntu:~$ sudo mdadm --detail /dev/sdb mdadm: /dev/sdb does not appear to be an md device
ubuntu@ubuntu:~$ sudo dmraid -s /dev/sdb: "sil" and "hpt45x" formats discovered (using hpt45x)! ERROR: sil: wrong # of devices in RAID set "sil_agafdhcebccj" [1/2] on /dev/sda ERROR: removing inconsistent RAID set "sil_agafdhcebccj"
I've got some files for work that I'd really like to get off there. I've played with unix a bit in college and I've ran ubuntu before, but usually using the GUI, so a lot of this stuff is over my head. But from what I gather, my system thinks that one of the drives isn't a raid drive?
A section of the hard drive on my laptop is damaged but the laptop has genearlly been running fine as it seems to very rarely touch that section (once every few months). However, when installing some updates the computer has hit that section which means it becomes unresponsive and makes a nasty clunking sound every 10s or so. Because of this I've had to abort the update but now whenever I try to run 'dpkg --configure -a' to sort out the problem caused by the interrupted update I get the same freezing up and clunking. The message that appears when I run the command is adding extension /usr/lib/openoffice/basis3.0/program/mailmerge.py... and then it freezes.
