I went and fdisk'd a USB disk and put the Fat32 filesystem onto it. Then I thought I ran dosfsck over it which I thort formatted the disk - apparently not. Then I copied a bunch of files and directories to it. Now I am unable to recover the files and data. In the rare instances when I perform a sloppy mount I see directories named 001, 002, 003 and 004. These directories variously contain files named 001, 002, 004 (no 003) etc.
Fdisk gives me:
I don't know enough to use dd, kpartx, parted, partmon, partprobe, partx et al
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?
I just tried to burn an ISO to a CD-R in K3B, and it finished with the message "written data in track 1 differs from original." I get that a lot; until now, I blamed it on my failing CD drives . What can I do to avoid it besides burning at a slow speed? I know that, having heard years ago that I should burn at 4x; but my new DVD-RW burner's slowest writing speed is 16x. (I'm annoyed at that. It was a Christmas gift, and I didn't think of specifying a write speed. I wouldn't be surprised if new CD drives can't burn at such a slow speed, though.)
I have a SATA drive that worked fine. Then I installed two more hard drives into my system. When these hard drives are installed, if I try to access the SATA drive in Linux, it will start lightly clicking and then the drive will become unavailable. If I power on the machine without the other two hard drives then it works fine. What could be causing this to happen? I don't think it's heat because the two hard drives are far away from the SATA drive.
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 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 am building a home server that will host a multitude of files; from mp3s to ebooks to FEA software and files. I don't know if RAID is the right thing for me. This server will have all the files that I have accumulated over the years and if the drive fails than I will be S.O.L. I have seen discussions where someone has RAID 1 setup but they don't have their drives internally (to the case), they bought 2 separate external hard drives with eSata to minimize an electrical failure to the drives. (I guess this is a good idea)I have also read about having one drive then using a second to rsync data every week. I planned on purchasing 2 enterprise hard drives of 500 MB to 1 GB but I don't have any experience with how I should handle my data
I recently purchased 3 new WD cavier green 500gb drives with the intent of building a raid5 array and running linux. Admittedly I purchased without doing enough research and now I have serious doubts about running an os on raid5 with the onboard controller.So now I am thinking I should run one drive as an OS drive and mirror the other two. I don't have a fourth drive unless someone can convince my wife I need a fourth after already buying 3....
Is it possible to have multiple distributions where ALL distros save their docs to the raid dives? That way I can wipe/install the os and keep my files? I seem to recall that I can be done, just need someone to point the compass.
I have approx. 30x Western Digital SATA 2.5" hard drives ranging from 80GB to 500GB. These are ex-Tandberg RDX QuikStor backup drives that I no longer use and would like to use them as spare laptop hard drives.The only problem is upon installing the drive in a laptop it prompts for a hard drive user password.
Are there any open source methods to wipe the password (and data; I don't care about that)? I've tried using various wiping methods (dd, dban etc.) but the password still remains.Any help is greatly appreciated; I really need these drives.Plugging it in via a USB HDD enclosure shows as /dev/sdb but does not respond to (c)fdisk or show any partitions (/dev/sdb1 etc).
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 was thinking about this for a while and I haven't come across it in any of my reading. Could you split an os over two drives? Example: drive hda, 35GB xp - 5GB fat32storage / hda1 8GB root - 2GB swap drive hdb 10GB usr - 10GB home -10GB var / hdb 10GB root linux#2 hdb 1GB swap - 9GB user - 5GB home - 5GB tmp I hope I made this clear enough I'm sure someone must have tried this before. Maybe I got too much time on my hands.
I have Fedora 14 installed on my main internal drive. I have one Fedora 14 and one Fedora 15 installed on two separate USB drives.When I boot into any of these drives, I can't access any of the other hard drives from the other drivesll I can, but just the boot partitions.Is there any way of mounting the other partitions so I can access the information?---------- Post added at 12:42 PM ---------- Previous post was at 09:34 AM ----------I guess even an explanation on why I can't view them would be good too.
I'm trying to setup a dual boot system with Windows Vista 64 (already installed) and Ubuntu 10.10. I added a new drive which is identical to the one Vista is installed on. When I boot into the LiveCD I can see and mount the second drive and edit it in Gparted. However, when I use the installer it will only bring up the drive that already has Vista installed.
I have a 3 year old PC with 4 internal SATA ports. My old SATA hard drives, all smaller than 2TB, work fine. If I buy a 3TB SATA hard drive, will it work in Linux? Will Linux with GRUB be able boot from such a hard drive without a BIOS upgrade? With a BIOS upgrade? It's fine for me to upgrade my Linux to the newest kernel.
I'm renting a dedicated server with a company that claims that the server has 2 hard drives in a software RAID 1 array, but I need to make sure that the server really has the 2 HDD, and the size of the 2nd drive... how to do that ?? system is Centos 5.3
I have a FAT32 external USB hard drive with a bunch of stuff I want to copy onto a RHEL server. Is it as simple as it is on a Mac or PC where I just plug it in and it will show up, then I can copy all the files off of it?If it is, how do I safely remove the drive after I'm done with it?
I have one machine with two disks that I'd like to install Slackware on. I'd like to have the root folder and installed folders on hdb, and just have have hda as a disk I can use for storage (without any home directories, etc.). My problem is, I don't know how to make this boot, as I think LILO is installed on the primary drive, but the boot folder is located on hdb. I tried doing this before and was having problems booting, so I was just going to go through the whole process again, but don't really know the correct procedures.
I'm not a stranger to Ubuntu Linux and I was using it for a couple of months with no problems until last week when I turned my computer on and it would go no further than the boot screen and it said 'Error- Insert System Disk'. So I inserted the system disk (Ubuntu Linux 10.something) and after waiting 10 minutes for it to load up it said 'Installation failed, desktop session will now be run and you can try installing again'. So I tried installing whilst on a desktop session and I eventually got to step 4 of 8 and it lets me go no further. This is what step 4 of 8 is:http://oi54.tinypic.com/mx2g79.jpg
And so I cant choose any disks or partitions and so it wont let me go any further. How do I create one? I'm currently running on desktop sessions and they take forever to load up and I cant watch videos or anything because there is no flash. By the way please try and explain to me really simply because I am quite dopey and I wont be able to understand posh complicated computer words.
I'm not exactly a newbie to Linux and it's OS, I have been using Ubuntu since the 8.xx release. I have two hard drives in my system, Hard Drive #1 is the primary drive and is 250GB, this hard drive is only used for Windows 7 Pro 64bit. The second hard drive is 320GB and split into two partitions. The first half has Windows XP Pro on it and the second partition has Ubuntu 10.04 on it. Both are split evenly at 160GB each. Here's how I did it, I first started by loading Windows XP Pro onto second hard drive, using the entire drive, once all updates and settings were applied I then installed Windows 7 Pro 64bit onto the first hard drive and used it fully. Once all settings and updates were applied I restarted the computer and it loaded directly into Win7, which is to be expected. I opened my computer, browsed through the second drive to make sure all files were intact.
I then downloaded and created a USB installation drive for Ubuntu 10.04. After the creation of the USB drive I proceeded to install Ubuntu 10.04 on my second drive, using half the space for Windows XP Pro, and half the space for Ubuntu 10.04. After that was all setup and done, I restarted one last time. Low and behold Ubuntu 10.04 and Windows 7 both appear on the boot menu, however Windows XP Pro does not. I panicked for a few short seconds but after logging into Windows 7 I realized all my XP Pro files where safe. So now I have 2 hard drives with 3 operating systems. Hard drive one has Windows 7 only and hard drive 2 is split between XP Pro and Ubuntu. However I cannot get Windows XP Pro added to the boot menu no matter how hard I try. I'm not entirely confident using the terminal as I am just starting to learn programming, but I know how to enter the commands and get things moving.
Every website that I look at tells me I need to start by editing some grub/menu.lsd, which for some reason does not exist or is "invalid directory". Some websites say I need to run "sudo apt-get grub-update", which again is an invalid command. Here's what I need. A step by step tutorial on how to add my XP into the loading menu. Example of step by step includes "Step 1: Open Terminal" and etc... It needs to be basic and down to earth. Don't just tell me to run codes and type a bunch of junk because that doesn't seem to work for me. I do not know what (hd,0) or (hd,1) means, but assuming the websites are correct, (hd,0) would be my Windows 7 HD and (hd,1) would be my Windows XP/Ubuntu HD?
I'm working on creating a bootable Linux CD to distribute a sandbox environment to customers that will work on multiple PCs.One requirement of this environment is that we do not want the user to have any access to the underlying hard drives in the computer to prevent any accidental and/or malicious damage. I can prevent the disks from automounting with a few udev custom rules, but is there any way to prevent/block the user from manually mounting the hard drives after boot up.
I've been through a lot of the posts already, but nothing seems to solve my problem. I have Ubuntu 9.10 and Windows 7 dual installed (Windows was installed first). Everything has been working fine until a few weeks ago when I accidentally left a USB drive plugged in when I restarted my computer from Windows.
Ever since then, whenever I have restarted my computer from Windows grub2 has failed (it does not fail when I restart from Ubuntu). I get a varying message like Grub loading. The symbol ' ' not found. Aborted. Press any key..where the part between the single quotes is usually different each time. When this happens I have to reinstall Grub2 from a live disk, which is becoming a bit of a pain.
I've been reading around, but I don't really have a great understanding yet of how hard drives and partitions work in general, and so I haven't been able to work out what the source of this problem is.
