Ubuntu :: Usb Stick Data Not Being Properly Deleted?
Mar 31, 2011
Has anybody noticed that delete in Ubuntu 10.10 is only compatible with Ubuntu. E.g. I have a usb stick with 2 movies on it. Delete them using ubuntu's Gui just right clicking files and move to thrash so the drive looks empty. then i physically remove the drive and put it into a windows xp machine and all the files are still on the stick just put into a folder called thrash.
I also reformatted the usb stick Fat32 inside ubuntu and when i put it into the windows machine the file names were still there. (The movies were currupt and unplayable in Windows.)But still its very strange I suppose i'll just have to Blow up my usb if i ever need to destroy the data on it.. Just let me know if this has happened to you guys before. (I had Bootable Backtrack 3 on one of my old usb's that I gave to a work colleague.
I know that deleting and reformatting only deletes the indexing info for the OS but i always thought that deleted files couldn't be accessed by the average computer user.

I am trying to get the Asus "My Cinema-U3100 Mini plus" DVB-T USB stick to work on my lucid 32bit with 2.6.32-27 kernel - with no great success so far. And this despite searching through forums and following the instructions given on [URL].
The USBID is in fact
Code:
ID 0b05:1779 ASUSTek Computer, Inc.
Which is exactly the one shown in the list of supported devices on LinuxTV. I have implemented all modifications and corrections to the source files as outlined in the above LinuxTVWiki instructions.
I also added the boot option
Code:
usbhid.quirks=0x0b05:0x1779:0x0004
to grub2 in order to overcome the (initial) problem of the tuner being recognised as a HID device.
My dmesg output after plugging in the device now shows
Code:
Jan 27 17:44:50 jens-laptop kernel: [ 1086.358488] usb 2-5: new high speed USB device using ehci_hcd and address 6
Jan 27 17:44:50 jens-laptop kernel: [ 1086.495359] usb 2-5: configuration #1 chosen from 1 choice
When I try to compile the af903x driver using
Code:
sudo make
The response on the screen is
Code:
make -C /lib/modules/2.6.32-27-generic/build SUBDIRS=/home/jens/Desktop/Linux_PC_AF9035_Afatech_2008.12.17/Linux-32bit_AF9035_20081217/AF903x_SRC modules
make[1]: Entering directory `/usr/src/linux-headers-2.6.32-27-generic'
CC [M] /home/jens/Desktop/Linux_PC_AF9035_Afatech_2008.12.17/Linux-32bit_AF9035_20081217/AF903x_SRC/af903x-core.o
In file included from /home/jens/Desktop/Linux_PC_AF9035_Afatech_2008.12.17/Linux-32bit_AF9035_20081217/AF903x_SRC/type.h:4, .....
make: *** [default] Error 2
My knowledge is limited and I have no idea why I am getting all these warnings and finally the error message. Also, is there a way to tell when (or if at all) driver support for this device will be implemented in the Linux kernel?

I launched a script using rsync and the option -delete-before, however the destination folder was the wrong one. I noticed it only seconds after but it was still too late. In less than 5 sec rsync deleted over 200gb of data on my external hard drive... It is not in my Trash nor on the HDD trash but it's not possible that the data were ereased in less than 5 sec! (I dont know how rsync handle deletions.) I know I am really stupid but is there a way to get back all my data (mainly HD movies in mkv, mp4 and some avi)

I have somehow managed to eradicate all of my films and music...I was going to update my external HDD (typical) and so I highlighted everything and went to drag it. My finger kind of slipped while the cursor was in the the same folder and I got a message saying something like:"Source file is in this destination. Cannot move. Do what?"There's me thinking not much can go wrong at this point so I clicked "Skip all".Everything disappeared
The file system says there's still only 500GB free on my 1.5TB, so the files are there but I just can't see them.how I can get them back?There's nothing in my 'Deleted Items' and I had a play with scalpel and PhotoRec and I either couldn't get them to work or they said they'd take way more time than I have.
Edit: Where did that smiling devil come from? That's really not how I feel right now.

I just made a very stupid mistake, and in result I just deleted almost everything on my windows 7 partition. I followed this guide: [URL].. for how to access my windows partition from ubuntu and it worked, but then I decided to rm -r the whole thing thinking it was a copy. I have no restore disks or any other type of backup. I know this maybe be impossible, but is there any way to recover my data?

I tried to recover deleted data using testdisk tool and now my partition table have some errors. Even though i have 3 partitions and 1 unallocated disk fdisk -l shows only 1 partition

vishnu@vishnu-laptop:~$ sudo fdisk -l
[sudo] password for vishnu:

I erased my partition table. Can anyone recommend a good method of reconstructing it? And if this is impossible, can anyone recommend a good method of data recovery? I had an ntfs partition with windows 7 and a larger ext3 partition that ran Debian.
I'm running Test-disk on the SystemRescueCD at the moment (cross your fingers).

As usual I was notified that there was an update available via the Update Manager which I duly accepted.I was then confronted with a popup which advised that there was a Distribution Upgrade and that it was to be a partial upgrade.
Finding that I would not go away I accepted the data finding that 9 packages were made available and 33 unused ones were to be deleted. As this is my first experience of this is it something I need worry about and if so what should I do about it?

I was trying to delete a logical drive in windows xp and the damn disk management tool in windows not only deleted my other windows partition but also my linux /data ext3 partition. Now I have a unallocated space in place of these partitions. The data is still there but the entries in the partition table have been removed. So how do I recover my partition. I was trying to use the following tutorial. [URK]
I used the sudo parted /dev/sda -- and then rescue START END command and could get back the /data partition. But it gives me the following error while mounting the partition. mount: wrong fs type, bad option, bad superblock on /dev/sda7, missing codepage or helper program or other error. In some cases useful info is found in syslog - try dmesg | tail or so.
What does this mean. How to I fix this? Also when I try to recover my windows partition using parted it scans for a while and then does nothing. It doesnot ask for writing the lost partition in the partition table. What do I do?

My wifes computer, IBM desktop, running XP, was hit by malware. I managed to save the data and tarred it and copied to a USB memory stick using my Linux box Ubu 9.1). I checked and saw it had been truly saved. Two days later I put stick in USB port and it was not recognized (usually any hot plugable device shows up immediately on desktop). I have tried plugging it into a windows machine and nothing was found. We are both very desperate at this apparent loss but because something similar happened with an Iomega zip disk.

I deleted by accident a folder containing a VMware server virtual machine, that contains most critical information. The host OS is CentOS 5.5, which I believe by default uses Ext3.I shut down the PC intermediately after noticing this.Is there any chance of recovering the files? Would they be able to mount to the same or another virtual machine?I need to get this information somehow, there are no backups.

Recently, I started protecting all user-accessible filesystems on my Sidux desktop machine with LUKS. Before that, I would regularly erase traces of deleted data, and I wonder if this is still necessary.
It would be most valuable to me to be pointed towards a good introductory article on the underlying mechanics of LUKS and cryptsetup, as there are a few more minor questions to be answered. Unfortunately, I lack the necessary mathematic and cryptographic background to understand scientific papers.

I have a probably kind of unusual problem - when a USB stick is connected to the PC and data is copied from/to that stick, I need to know how much data has been copied. The data itself if not interesting, just how many bytes. I unfortunately don't have access to the program that does the copying, and most of the data doesn't end up on any drive (it just gets read and discarded), so I can't simply check the size of a target directory or something like that. I have had a look at usbmon, but that seems to produce way too much data - the normal case would be around 10 gig of data being read, and I can't have that blown up by a factor of 10 and lying around on the hard drive

I had a working Ubuntu 9.10 with Windows 7 installed, and i was writing an image of IPCOP [URL] to the USB drive incorrectly, i did mkfs on my primary partation i.e. /dev/sda1 now i am trapped in situation, i was trying to write and usb-hdd image of ipcop on USB Drive, while doing so, i have given following commands
1. mkfs.vfat /dev/sda1
2. e2label usb-pen
3. zcat filename > /dev/sda1
* now the stupid thing i have done, is given /sda1( My HDD ) instead of /sdb1 (USB Drive), it has successfully loaded IPCOP bootable on my primary drive, and my laptop is not working now.
Laptop Partation Info:
/dev/sda1 - NTFS (Windows 7 Prof)
/dev/sda2 - NTFS
[code].....
now i want to get my partitions & data back, if anybody have idea about how to get rid of this situation. The good thing i have done, is that, i didn't tried to install anything on the drive after this happened, with hopes that i can get my data back i guess that it can be recovered but confusion is that, which data recovery software to use, and for linux or windows, as i had my data on NTFS filesystem and currently there is Free Space and EXT4 partition.

I have accidentally ended up in deleting my root directory while I blindly fired command while watching movie.
I fired following command
#rm -rf ~/<SPACE>*.out
instead of this command
#rm -rf ~/*.out
Things already done:
1) Created /root directory relogged to get some of basic settings of gnome and Desktop.
2) Things went well now when I login my desktop ,gnome environment and other things looks to be working well only prompt on my terminal has changed. I can fix it any ways.
Things I want to ask:
1) I haven't studied much about contents of /root directory to best of my knowledge is it like other user's home directory with some basic configuration files for mostly required applications. SO my question is have I lost any thing important system file or something?
2) If I have lost any important configuration or system data how can I recover it without reinstalling whole system? (My opinion about this is, It is quite possible but to do so, as far as I know capabilities of linux. But I still want comments from experts before I try any things on it because I don't want to backup my whole HDD and reinstall the whole stuff again for me and also my sister's stuff in MS.)

why nautilus is sorting my files in such a weird way? I would think it would sort numerically by the first number, then second number, etc.

I'm about to ditch Freenas as my NAS software and make it an Ubuntu server box. The mainboard is an Asus AT3ION-T dual core Atom board. Freenas runs happily from USB stick. I have no optical device to install Ubuntu from and would like to install Ubuntu Server to a USB stick.

I 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.

I've been using Excel from OpenOffice with moderate success for the last year. Now I've just tried to open a new spreadsheet and I'm suddenly getting a highly condensed view. The cells are about 1mm X 4mm. If I expand them by selecting and dragging, then try to copy data from another spreadsheet onto the new one, the data shrinks to the small scale -- unreadable.
