can I change the ECC code for a block of a file stored on a flash drive by any means ? of a file stored on a HDD (though I don't think there would be a difference between the two)Maybe , through some hardware interrupts or anything like that?Also if possible I need the solution to be in C/C++.
View 4 RepliesI recently had a problem with an absolutely gobsmackingly huge .xsessions-error file growing in my /home partition (over 200 GB--the only reason it stopped growing was that there wasn't any room left). So, I deleted it, and then to see what problems had been causing the file to grow so huge, I rebooted the computer to regenerate it. Big mistake.Since then, I haven't been able to boot. The process hangs when it reaches the step of mounting the /home partition. Luckily, I have my install CD, so I was able to boot into that environment. First, I checked disk integrity--everything was just fine. Then, I tried booting into the liveCD environment. Jackpot! It reports that the bus between /dev/sda6 and itself is timing out when I try to access the former home partition, but I can get into my / partition just fine.I have just edited my /etc/fstab file to *not* know about /dev/sda6, so hopefully it will boot properly (though of course without any access to the files on /home) soon. If this works, I will update.But, does anyone else at all know anything about this sort of problem and what I can do to fix it? Regenerating my /home partition on / merely postpones the problem and doesn't actually get me any of my files back.
UPDATE: Well, that didn't work. Actually, it sort of did, but not quite the way I wanted it to. I was indeed able to bypass mounting the /dev/sda6, but I was not able to boot into Xubuntu since the graphical log-in manager failed and none of the ttys started. The failure mode was, however, interesting. It did not merely fail, but instead flickered violently with a frequency of several seconds until I tried switching to one of the virtual terminals (C-M-!, if anyone is interested).
How to find the filesize of a flash which is not exactly stored in the temp but redirected by a fd.

View 4 Replies View RelatedIt's many years since introducing of installation of Linux live CDs like Ubuntu from USB flash drives. I never been able to use such services on my 2GB KingStone flash drive, because it's sector size is 2048 and the famous linux error: "Not all ... support more than 512B sector size". Although I formatted my flash drive many times and even erased the whole partition table and cleared all flash contents with 0xFF values but it still has sector size of 2048.I want to know where the hell those softwares like "USB Startup Disk Creator" in ubuntu and kubuntu and fdisk in almost all linux distro's get to know that the sector size is 2048?
View 2 Replies View RelatedI want to find a simple and quick way to permit my application to bring a file located in my file system and write it into an external USB device. I have to use Bulk Transfer Only mode that means to use stream of characters only. I looked through the LibUsb library using it in my IDE I can transmit a string. To transfer a whole file I suppose I've to dodge the file system building a char sequence that permits to recognise a file in the file system and to put it into the usb device.

When I installed ubuntu, I selected the encrypt hard drive option. How is this encryption when it seems like the space is just being replicated? And if I want to free up the 50 GB of space taken up by "ecryptfs", how do I do it?

Here is a way to prepare a USB flash drive to save your kickstart file to it, and then read the kickstart file from the USB drive during a new Fedora installation.A USB flash drive is recognised by the Linux kernel as just another hard drive.This is how I set up my USB flash drive to use it to store my kickstart file on.You will need a working Linux system to set up the USB drive.

I am pretty much a noob when it comes to Linux. But I desperately need to do exactly what the title of this thread says.I have this ISO file which is a bootable CD image. But instead of booting off of a CD, I want to boot from a USB flash drive. I understand that I can't simply just burn it with ImgBurn or whatever, and then just drag and drop the files and folder to a USB flash drive. Because hidden files, bootloader, etc. would not be visible and not copied. I know I'm in for some special software in order to copy every single byte from that ISO image to my USB flash drive.
I did try extracting the ISO with PeaZip (7-zip based) under Windows Vista, but that didn't work out very well. It resulted in a few files and folders, totaling in at about 2 KB, while the source ISO file is actually some 50 MB. WinRAR, on the other hand, would simply just create an empty folder where to put the files (no files created/extracted), flash before my eyes and call it a day ("complete").I have learned from other posters on other forums that there is this Unilx program/command called DD. How can I use DD to accomplish this task?
For shifting forward, we select the required part and press tab the number of times we want to move forward.

I usually develop python code with emacs, emacs being in python code. On my desktop a version is installed and/or configured that way, so I easily can choose a region in the code and simply click on a menu option to comment out this block of code (i.e. at the begin of each line in the selected code two '##' are put). That is very convenient.
However, on my Laptop, running F12 and emacs 23.1.1, this menu option is missing! I searched within google and found the hint that by pressing 'C-c #' I also can comment out a selected region. But on my emacs it says: 'C-c # is undefined'. Am I missing something? Anyone any idea how to fix/install/update/solve this problem, so I can easily choose a couple of python lines and comment them out?
We have setup a separate partition to keep our audit files, but I am at a loss to figure out how to redirect the log files to be stored there instead of the default.

I'm trying to setup a print server in Fedora 13. I've made it using CUPS and when I send something to print from a Windows PC it goes ok. My main concern is to know where is the spool file stored when a file is sent to print. I've seen in many forums that it is stored in /var/spools/cups. What I only see here is a file name c000XXX with some information about the printing job. I'm using hold print for this printer and before printing out anything I can't find the spool. I've tried cups-pdf and it stores a pdf file in a route but this is not enough for me. I need to know where the spool data is stored in order to know from who is the job being send.

I have recently installed Ubuntu 11.04 from the alternative installation CD; the installation was just the command line system. On top of this I have installed xorg and awesome window manager. The only problem I am having is with sound; I am unable to hear sound played through both browser-based Flash and locally stored files.
Is there something that I have to do before I can use sound? Edit: I have solved the original problem however I would like to know if I can remove pulseaudio as it seems that I am only using alsa.
I have machine that I used to VNC to on my network with Remote Desktop Viewer from my Fedora 12. When I first connected I checked the checkbox that I wanted to store the pw. Now the pw on the other machine has changed but Remote Desktop Viewer does not ask for a new password, it just gives me a black screen, like I am connected but I can't see anything. I'd like to know if anyone knows where this pw data is stored on the system so I can start fresh. I already tried uninstalling Remote Desktop Viewer and installing it again.
