I was using dd if=/dev/zero of=/dev/user name/wipe.conf however i got a message that my hard drive is full.
lots of this is scary - dangerous. what is the best way to fill in random or zeros in deleted files without the hard drive filling up ?
I have an external hard drive connected via usb cable - /media/New Volume - and mounted in Ubuntu 10.04. How can I "write zeros" to this drive or maybe write random characters in an effort to wipe data on this disk?

I want to view a hard drive and see if it has all random data, or random data mixed with zeroes. How can I do this? I prefer to do all this in linux if possible without a gui...so looking for any cli tools to view with.

column 1:
0,0,0,0,0,0,0,0,1,1
column 2:
1,1,1,1,1,1,1,1,1,1
The first two rows of the second column are being replaced into the last two rows of the first column, now I even checked in visual studio and it works fine there. A friend tried my code and he gets it even worse:
column 1:
0,0,0,0,1,1,1,1,1,1
column 2:
1,1,1,1,1,1,1,1,1,1
As far as I've seen it must be a problem with GCC, unfortunately I need to have this up and running in GCC no matter what.

I'v been trying to install Ubuntu (and actually all other dists of linux (in hope of succes), but running ubuntu on my other machines and prefer it) on my old laptop. Laptop Acer Aspire 1312XC. Have just run a 24 hour RAM test it turned out ok. Have tried with other RAM blocks in aswell. The install freezes at random points in the installation. Mainly when trying to copy files to the hard drive. The only thing i've succeded in installing was Ubuntu server and windows XP. I have tried with ACPI off and all the other special atributes. No success so far.

View 3 Replies View RelatedI searched the forum with various terms and didn't find anything, so my apologies if this is a common and/or newbie problem.It seems that when I have a USB driveplugged in to switch the files around, those that I delete are still taking up space. I first noticed it with a Chinese MP3 player and thought it was the player being crappy. I could still play all the songs that were supposedly gone. Today, I noticed it with a little thumb drive that I've had for years. I plugged it into my husband's computer running winXP, and the files showed up in a weird, unusable form. I was able to delete them for real.
View 4 Replies View RelatedI just booted one of my computers from a usb drive I had installed Ubuntu 10.04 LTS to, and when I booted it up on that computer, it worked fine. Then, when I powered down the computer and booted it back up to the main hard drive, it booted to the same that my flash drive was running, but my flash drive was not plugged in!! How is this possible? Did it copy itself over my other operating system? There is no trace of it. By the way, that, too, was ubuntu 10.04.
View 2 Replies View RelatedIf this post is correct [URL] I can expect that it will take more then 16 days to fill my 2TB partition from /dev/urandom. That's not workable for me. dd if=/dev/urandom of=/dev/sdxx has been running for 36 hours, and I need to finish setting up the filesystem. But I also need to make a "professional effort" at encrypting the partition. I am supposed to fill the partition with random data, to strengthen the encryption for a LUKS partition. It seems that if the bad guys get the drive, they have much more time to try and crack it, then I have to encrypt it. Ok, so I can try Code: sudo /sbin/badblocks -c 10240 -s -w -t random -v /dev/sdxx How long can I expect badblocks to run on a 2TB partition?.
View 3 Replies View RelatedSo I built a new system few months to act as a development/"mess around with" server with an Asus Mobo and a Q6600 processor and 8 gigs of ram. Along with file, web and app hosting, I also do some virtualization on it... or atleast I had hoped to.
Ever since the first install, I've been randomly getting crashes and lockups. Sometimes it would just dump an error to the screen but stay alive, and sometimes it would dump an error and then lock up fully. The error mentions something about "kernel not tainted" etc. I will post the detailed error once it comes up again, as I have just formatted it again.
Other problems include downloaded files becoming corrupt. Files downloaded through any means (wget, torrents, ssh, ftp etc.) seem to randomly get corrupted (ie: the hashes are wrong).
I currently have one WD 150GB raptor as my primary OS partition, and 3 WD 1TB greens as my storage in an mdadm raid 5 array. At first, I had thought it was the raid array or it's drives causing issues. After painfully transfering the data off of it, I took the drives out and tried to run ubuntu with just the OS drive for a while. This still had the same issues. I then put in only one of the 1TB greens and had the same issue...
I downloaded WD's hardware diagnostic tool and ran full scans on all the drives. They all check out fine.
I left memtest running overnight and it had no errors either.
Most recently, ubuntu would not even install. It would get stuck at the stage of partitioning, and the keyboard lights would flash. After much googling, I tried popping in "noapic nolapic" to the end of the grub string, and it managed to install.
Now, I'm in a fresh system and just wgetted vmware server. However, it wont untar, I just realized the MD5 hash doesn't match!
So definately not the memory or the hds... I'm assuming it has to do with the APIC? From what I found on google, it seems as though this is only needed for the install.
Do I really need this to be on the boot string too? From what I understand, APIC allows processes to be divided out to the least loaded CPU. Having a quad core, I'd rather leave this on since it seems somewhat beneficial... I have yet to try putting this into the grub yet since I'm offsite and need
As a side note, this latest install is using just the WD Raptor as an OS drive.
And I'll post up the dumped errors if I get them again. There were none dumped out when the vmware download corrupted. The message format is very similar to the one here: [url
However, sometimes it mentions ext3 (or one of the other filesystem types I had tried with thinking it was a problem with ext3) Again, the error message is not the EXACT same, however the format is very similar...

Code:
However, when I navigate to the gvfs-metadata folder, the home file is there, 124.8Kb in size, of unknown type and gedit can't open it. The file in /tmp/, on the other hand, doesn't exist.
Why is Terminal using a deleted file, and why is the home file being reported as deleted when it isn't?
I don't know whether this is a bug or feature. But I find the fact that the Trash in Gnome doesn't delete trashinfo files a security liability.
I found in ./local/share/Trash/info thousands of .trashinfo files named exactly like the files deleted and each one contains the date of deletion.
I thought when I empty the trash bin every record of the files were removed. I understand that there are forensic ways to recover data and rm isn't very secure with journaled file systems, but forensic recovery isn't 100% and if the disk is written over several times the data is gone.
Here you have a permanent list of all the files you've deleted, without you knowing and the dates of deletion. IMO that's too much information.
Update: Weird after removing the files manually and then trying to delete files again using the trash I found no .trashinfo files, this time. So they were probably leftover files, but they didn't have a different owner/permission. Could this have been an issue and now fixed? (running Lucid)
I need to rename some files. They are named:
NP1-1.mp3
NP1-2.mp3
NP1-3.mp3
[code]....
However, as there is no lead 0, the order gets confused by some software (some software mistakenly lists it as NP1-1.mp3, then NP1-10.mp3). I'd like to add zeros so the files are named like this:
NP1-0001.mp3
NP1-0002.mp3
NP1-0003.mp3
[code]...
How can that be done?

View 2 Replies View RelatedI'm installing fedora 12 on a laptop using the live cd, and I have a few questions about the encryption process.
First, I'd like to fill the drive with random data. I've read the fedora documentation and it suggests using the following command: dd if=/dev/urandom of=<device>. The installer didn't offer an opportunity to do this, so I opened a terminal and typed the command. I expected it to take hours on my 160 gig hard drive, but it only took about 3 minutes, and indicated about 600 megs of data had been written. Did I do it correctly? According to palimpsest, my boot partition is sda1 and the other partition is sda2, so that's the one ran the command with.
Second, I need some advice on what to encrypt. The installer shows me the following layout after I select encryption:
LVM Volume Groups
Hard Drives
I know I can't encrypt boot, but I can encrypt lv_root and lv_swap. But is it necessary to do that? And tell me the pros and cons of using a boot loader password?
I encrypted my hard drive on my media PC but it's really annoying having to type in a password every time I turn it on. I chose a short password so it was quick and easy to type in but is it worth encrypting data with a weak password?If the computer is suspended, someone could come along and resume the computer. They would be presented with a locked GNOME session) but the data would be unencrypted; does this go against encrypting the hard drive? Or does the locked GNOME session provide enough security to keep an intruder out?
View 9 Replies View RelatedI have recently bought a new laptop, installed my first linux OS on it (Ubuntu 9.10) and an external hard drive with 500GB on it for backup. For the first few days my external hard drive was working fine, but then eventually it wouldn't let me copy/move/delete stuff to and from it. So I kept trying to change the permissions but it wouldn't let me.
I figured this would be a very very common problem, so I looked up some forums to try out the methods but they didn't work. So I thought I would ask you guys for help because I am pleased with the support. I wouldn't think this would be a hard problem to solve.
What I want to do is pull data from any of the hard drives attached to my Linux box from my Windows machine. I have been moving small amounts of data from the drives to my OS drive and those parts share easily, but I want to move away from that method to move large amounts of data at the same time.I have tried using Samba as it is used for file sharing between systems and that I have to give my Windows box permission through Samba.
Trick is, I'm not sure where to start, though I have an idea and wanted to know if this is the right track before I start editing my file system.
I have an external hard drive that has all of my Apple Powerbook G4 files on it. I plugged in my "Journal Extended" external hard drive into my new HP laptop with Ubuntu 10.10 on it.
All of my files are on the hard drive still, however lots of them have a little X on the folders and when I try to open them it tells me I don't have permission? How can I force the permission for everything on my external? It's my own files and I can't even access them lol.
I want to access my hard drive to copy over my old documents. So I boot into a LiveUSB, mount my ubuntu partition, and then cd to my home directory, but I can't open it. I get "permission denied." I encrypted my whole home directory and know the password, but how do I "decrypt" it or login as the partition's root so I can access the documents that way. I'm booted into the USB, but can't access the home directory. I get "You do not have the permissions necessary to view the contents of 'jake'".
