Ubuntu :: 10.4.2 LTS LiveCD Using Hard Drive For A Swap File?
Jun 22, 2011
I am concerned about the LiveCD touching my HDD at all. Is this a factor, such as using HDD space for a swap file? I thought the whole thing ran off my RAM. Anyway here's my specs:
MacBook Pro 500GB:
HFS+ Partition w/Snow Leaopard ~400GB
NTFS Parition with WIndows 7 ~100GB
EFI Partition ~200MB
1) Does this mean I have a "swap file" on there I don't know about? I assume both WIndows and OSX use virtual memory to manage RAM when running in their respective operating systems but does that mean Ubuntu LiveCD will use one of my winows or OSX partition's "swap file"?
2) Or is there an invisiable partition created for LiveCD to use on some unallocated space on my HDD (I don't think there's any but idunno)?
3) How can I be sure the LiveCD is not writing ANY data to the HDD? I don't believe I have ever explicitly created a swap file in either OSX or windows.
I have a laptop, running Windows Media Centre unfortunately, and I think the hard drive is hosed. I was wondering is there away of checking the hard drive for errors using the ubuntu livecd? I would put ubuntu straight onto it only there are various items within Windows that the owner needs to get.
As my harddisks are completely full I want to swap a 1,5TB drive with a 2TB drive to give me some breathing space. The 1,5TB is part of a LVM spanned volume. My simple question, how do I move all data from the one drive to the other drive without ruining my spanned volume?
I got a new laptop, a Dell D400. I want to swap my hard-drive from my old laptop into the new one, and did so... but then got an error stating that my CPU didn't support PAE.
As far as I was aware I hadn't actually installed a kernel with PAE enabled [as I always pick a real-time kernel for audio work]: but then read that lots of the newer distibutions are enabling PAE by default [which is what's caused the problem].
Is there an easy way of disabling PAE in the existing kernel? Or would it be easier to downgrade to another version of OpenSUSE? I'm on 11.2.
I burned the live version of OpenSUSE 11.3 (Gnome, 32bit) to a CD to test the compatibility of an HP Pavilion p6510f. Although Xubuntu 10.4 booted up fine, OpenSUSE did not. A message about RAID would appear (too briefly to read) and then the computer would reboot.I checked in the BIOS and found that the SATA drive has 3 modes: IDE, RAID and AHCI. The hard drive was set to RAID.
When I changed the hard drive mode to IDE, I was able to run the OpenSUSE live CD; but the change ruined my Windows installation. Windows doesn't boot under IDE or RAID mode. (I have reset the mode to RAID and am restoring the Windows installation.) Is there an option/argument that I can pass to the kernel so that OpenSUSE will work under RAID mode? (Since Xubuntu 10.4 was able to do it, I'm assuming OpenSUSE should be able to.)
RAM for older machines like I use is fairly cheap these days. But flash memory is just as cheap or cheaper. So I'd like to ask about the feasibility of expanding my system's memory using flash memory. And about whether creating a partition for swap on the flash memory, or whether a swap file on the flash device, is the better way to go.
By flash memory I have in mind mainly USB sticks or what are sometimes called "pen drives." But I do also have CF and SD cards that, with the proper cheap adapter (one of which I already own for adapting CF) could be used to create extra swap space. So, what is the current consensus on the feasibility/advisability of using flash memory for swap? I've read about the limited write cycles of flash being an argument against using it for swap. But recent reading indicates to me that the limited write cycles problem applies mostly to older, smaller-capacity flash memory. Some will come out and say that, for larger-capacity flash memory, the life of the device is likely to exceed the amount of time your current computer will be useful (I think I've seen estimates in the range of 3-4 years life--minimum--for newer, higher-capacity flash memory).
A more persuasive argument I've heard against using flash memory for swap is that access times for these devices can be much slower than SATA, and maybe even IDE, hard drives. That would certainly dictate against using flash memory for swap.
So, how about some input on this issue? Anyone using flash memory for swap? If so, what kind (e.g., usb stick or SD/CF)? Are you using a swap file or a swap partition? How's system performance? Likewise, has anyone had flash-memory-used-as-swap die on them? The consequences would undoubtedly be dire. Also, has anyone measured flash memory access times to confirm or refute claims about slow access times? Are some types of flash memory better/worse than others in terms of access times?
Upgraded win7 32bit with wubi but it installed the 64bit version of 10.04. Downloaded the 32bit version to an *.iso file. Unable to build a cd with the iso file because of lack of hardware. Is it possible to run the iso file from a hard drive?
I got a dell inspiron 1501 laptop with a 80Gb sata drive what is the best solution to add data storage space for someone that love to have multiples operating systems at hand Note: I use mostly linux so I won't need to change my laptop for many years maybe ...
I have a 1.5TB Western Digital Caviar Green in a USB 2.0 external setup with an ext4 file system. I'm going to purchase a 2.0TB Western Digital Caviar Green in a USB 2.0 external case, copy the data over and put my 1.5TB in a fire-resistant box in another house. I'm worried about a couple things however:
(1) I'm worried about the long-term viability of _any_ file system years into the future. I've been storing my data on hard drives (instead of CDs, DVDs or BDs) for years now due to their higher reliability than optical disks. However, the file system used in optical disks is UDF which I think has much longer viability into the future. I'm not going to store terabytes of data on optical discs of course, so I'm wondering what I should choose for a hard drive file system. FAT32 or NTFS (due to Windows' 90%+ presence on the desktop, including still being used by Windows 7) may be the best choice, but I much rather have a open source file system, especially one that allows for permissions, timestamps, etc.
(2) As for my 2TB hard drive that I will be using for a while into the future, should I continue to use ext4 (I've had no problem with it thus far), but is there another file system that has better performance when storing and transferring gigs of data?
What is the best way to locate a file or folder in your hard drive? I have been trying to do that through searching in "Files & Folders" but it seems that the search is not thorough: it doesn't look for everything. I have an external drive that when it's connected to the computer I would like to search inside of it as well. The "Files & Folders" option does not seem to do that at all.
My parents bought a new hard drive for a laptop that I've owned for several years. It's much larger than the current one, so I plan on splitting it up to dual boot it with Ubuntu.I have no problem with partitioning a drive (I always keep a LiveCD handy), but my question is this: how can I go about moving the existing partition to the new drive? This is a laptop, so I can't simply plug the new drive into another slot.
Also, even if I manage to move it, will Windows still work on the new drive in a larger partition? I've had this laptop for quite a while, and I've lost the recovery discs that came with it a long time ago. I also have a lot of software without CDs to reinstall them with. This makes not reinstalling Windows a high priority.
What i really need to know is if there is a way to access a Ubuntu file system on a hard drive from a live CD. When i acess it now it just shows the Windows files on it, and i cant access the Ubuntu partition. What happened was this: I was trying to install Ubuntu on an external hard drive. I moved all the settings to the Hard drive so i didnt think it would affect my other drives. I mustve missed one of them because insteading of loading GRUB like it normally does, it came up with GRUB error 21 and did nothing. I tried to fix it, but nothing worked. I finally decided to unplug everything except the external and install it from there, so id atleast have a functioning desktop. As it turns out, my comp doesnt suport USB booting. So the only way i can use my computer is by Live CD. I was trying to fix things so i had both hard drives power supply unplugged. being slightly drowsy from staying up late that night, I plugged them in while my computer was on. the first one went in just fine, no problems. The second one though, also my master drive, i was having troubles pluging in. while i was turning it to fit in, it made a big spark and shocked my master drive. That drive had my MBR and Windows on it. Now It cant find a MBR, and i cant access the ubuntu partition on my slave drive. Is there any way to save this?? im 99.9% sure ive screwed myself over hardcore epically, but im hoping to save at least 1/2 my data.
I have a file on a separate hard drive and it wont allow me to delete it.how I navigate to it in the terminal so I can remove directory there? I plug my usb lead in and go /hoome/boo/Iomega_HDD (name of the hard drive)but I cant get there,it doesnt show up as a directory.
when I load into Ubuntu 11.04 from my USB drive, why can't I access the files on my internal hard drive? I mount the drive but I cannot see any of the music, videos or documents contained on that drive (which is also an Ubuntu 11.04 drive). I was wondering so I could copy those files onto my external hard drive and reinstall since my Ubuntu crashed.
I installed Ubuntu 10.10 beta yesterday and most of it is working very well. However, I ran into a problem with permissions today.I have a HDD containing my home folder and a HDD containing my data folder. The HDD with the data folder is mounted on /media/data/data_1.
I made sure I had set a+x rights on the file, tried executing it as root but the permission error stayed.When I copy that same file to my Desktop folder I can perfectly execute it.When it's located on the other hard drive I can't. I tried several command line scripts and they all work when I execute them from my OS hard drive,but not from another hard drive.
I have to locate and display the findme file on an XFS file system but the file is located on a second hard drive. The hard drives area number sda1 and sdb1know to change a directory, you use the cd command but I cannot remember how to do it for another hard drive. I tried cd /dev/sdb1 but I know that is not correct
I installed ubuntu off of my laptop and put the Ubunto file system on a 1TB hard drive off of a drive enclosure. Now the only way I can access Windows is if the drive is still connected to the laptop. NO EXTERNAL HD No BOOT MENU when I boot up.
Trying to install Fedora 12 using the 6 CDs. Trying to install on an older x86 box.Problem is that when detecting my hard drive, Fedora 12 recognizes it as a sda hard drive instead of hda hard drive. I have no SCSI connected to my computer what so ever. It's an old fashion PATA Western Digital hard drive.If I proceed with the install, Fedora 12 only installs 200MB of the OS from the first CD only. No options for additional software or anything.
I have a laptop with only 30GB storage and I want to install Lubuntu in virtual box but Lubuntu needs 5GB of storage space which i dont have. Could i use an external 160GB hard drive to act as the hard drive for the virtual machine without affecting the files that are already on the external hard drive
I've been installing/tweaking F12, and I've found something that I can't say I've ever seen or expected to find before: the contents of my ~/Documents folder has lost its permissions and ownership info. I restored it from a backup last night/this morning, and I've rebooted a few times since then. Other folders from the backup are OK, just Documents.I don't know what my options are. I could try to blow it away and restore it, but that doesn't answer what caused it. If there's a "relabel" or something, that might help... though I've never had to do it before. Could it be that after these two-and-some-change years, my hard drive is giving out? Good thing I have a recent backup... but it'd be a shame to lose all my work getting F12 to work again.
I have a Toshiba laptop that seems to be freezing on extended operations involving the file system/hard drive. (that's kind of a guess on my part). The system has frozen during the last day or two when I:
- try a large file operation with Nautilus - try exporting a large video file from Kdenlive - try formatting the disk for a new install of Maverick (I decided that with the new version almost out, I might try upgrading in case I broke my system)
What I see is the screen freezing and the mouse does not move. As I said, I tried installing the Maverick RC from the Alternate CD (I wanted to do a minimal install). The install hung on the partitioning step and the caps-lock key started blinking (though I don't get this in other cases). I have booted into my Lucid live-cd and a Puppy live-cd to try Gparted, with the same results - the system freezes (but the caps-lock key doesn't blink). Puppy HAS performed better generally, for example I was able to complete my large file operation (backing things up!) but it is freezing on the partitioning step.
What file system should I use to partition a slow and old hard drive? I know that ext2 was best for old computers which mine is not but I am using an old hard drive for extra storage and I was curious if anyone knew if using ext2 or ext4 would show any performance differences.
I have never used rsync before, only DD. But from what I have been reading, rsync is better becasue it will basically mirror your hard drive, thus being able to run the cloned software from the new hard drive. My problem is I do not know what is the best commands or even the basic commands to use in rsync. I am trying to make an image from a external hard drive to a usb drive. That way my chances of messing up he original software is not as risky becasue I'll just restore the image onto another hard drive. Does anyone know the best script to have rsync make an image file of a hard drive and place it on a usb drive and then restore it?
I had a drive that kept kernel panic'ing so my data center recommended using the spare hard drive to reinstall OS on, and import the data from the old drive. (they checked the hardware, it wasn't the hardware) The new install is done, and I need to mount the old drive and get backups off it since my data center does not provide management whatsoever.
It's the same OS on both (Cent OS 5.4 32-bit) I'm an advanced user on windows, but linux gets me. I can ssh in, do basic stuff like setup IP ranges and restart services. I normally navigate the box through SFTP so I have a gui. WHM shows me my drives as such
Found Disk: hda Found Disk: sdb
so I'm assuming SDB is my old drive and the drive I need to access. I attempted to follow instructions on
I have centos 5.3 installed. I plugged in a WD usb external HD, Icon is showing up on desktop everything is working formatted with ext3. I would like to have an entry for this in my /etc/fstab file, and I need to know how to enable Quotas on some files on it.
