Ubuntu :: Unmounting USB-drive (flash Memory) - Get Data Back?
Jan 6, 2010
I stupidly unplugget my USB-cable, which was connected to my Nokia music phone, just as if I were in Windows. What do I do? I've lost my music on the phone, or, it seems it may be there (the correct mass of data), but my phone now tells me there is no music... Can I recover this? And - what is the correct way to unplug a USB unit in Ubuntu? To make it work, and find the phone/drive - I just typed "sudo lsusb" in the terminal, and it found and opened the memory automatically... How should you unmount the USB, and maybe even how do I get my data back?

I would like to back up my flash drive in case it gets lost or damaged.the flash drive is bootable with ext2 and a fat partition.the drive is on /dev/sdb1.I think the dd command would back everything up and when restored to a different flash drive everything would boot fine and be as before.I was wondering wow should I use this command to backup and restore or if there is a better option.

I was wondering if there was a back up program that will back up the entire OS onto say a flash drive or an ext HD..

A friend of mine somehow managed to accidentally format her USB key the other day. It had all the photos of her daughter on it and she's more than a little upset about it.
I've told her not to fret too much just yet and that I'll have a look to see if there's any way to recover any of the data (specifically the photo's, she's not overly fussed about the rest)
I've had a look through the web, and foremost looks like it's the most promising option but I don't want to start messing around with it until I've asked my fellow ubuntu users for advice and thoughts.

Folks:What can I use to encrypt all data on my USB flash drive? If possible, could I use something that has a public Key, so I do not have to type in a password to access the information when I plug the drive into my machie, but will not open or display contant if the drive is plugged into anyone else's machine, unless they have the public key?

I am trying to setup my ubuntu machine to automatically log some data I am trying to collect and write the data to a flash drive. I have everything setup so that when the machine boots up it starts that logging process. The problem I am having is that sometimes (not always) ubuntu creates a directory with the same path that I expect my flash drive to mount to i.e., /media/data/ then my flash drive instead mounts to /media/data_/. I need to know the path of the flash drive so I can store my data on it.

I bought an external hard drive a couple of months ago and in the last few days it is having some problems.
Step 1, I turn it on and plug in the USB
/var/log/syslog:
Jul 28 13:52:39 bc1982 kernel: [61683.130027] usb 1-5: new high speed USB device using ehci_hcd and address 22
[Code].....
I turn off the drive, wait a while, then turn it on again in which sometimes it works fine, sometimes it doesn't. These errors have occured frequently in the past two days, but never before that
I don't know what these system logs mean, does anyone else?

I have an external DVD burner hooked up to an EEE PC 701SD. The disk has worked on a dell desktop computer, and a 701 (the first eee pc which I built the install on) without a problem, however when I boot up the install disk on the 701SD, I get a message telling me it's unable to download the kickstart file. It's being set to cdrom:/ks.cfg, which should work, but it isn't.... This exact same disk just did a full install on the 701 15 minutes before I ran it on this computer.

I had a corrupted superblock in my RAID boot drive (/dev/md0), which I fixed with fsck in Recovery Mode.However, after rebooting, the same boot-up problem (hanging for hours) persists.When I re-enter Recovery Mode to examine the boot drive, I found its superblock was corrupted again (which I fixed again using fsck).Is there a proper reboot procedure which is gentle on the boot drive, such that it doesn't corrupt it? Or, is something else amiss

I made a persistent install of Ubuntu on a flash drive. I made changes to that installation. The software (Unetboontin) sets this all up. I think it partitions it for you. How do I image that flash drive to another flash drive?

I have a simple C program that reads a 1 GB file from disk into memory.The first time I run this program, the process takes several seconds. But if I run this program again immediately after it finishes, the read happens almost instantly. What is going on here?My suspicion is that the operating system is realizing that the data I'm trying to read is still uncorrupted in memory (its been freed but not overwritten), so instead of reading it again, it just gives me the same block. I would really like to know what this process is called, or any Googleable keywords that would allow me to research it.
The reason I ask is because the size of my input data has increased. Now I need to read in a 6 GB file (my system has 12 GB of RAM), but I'm not observing the same behavior with the larger file. Each time I run the program the read takes an equally long time.

I've just installed ubuntu 10.04 on a Lenovo Thinkpad Edge. Problem is that it generally doesn't detect the USB memories that I've been trying to use. On two occasions it did in fact detect the flash memory, but it couldn't open/read it for some reason (USB memories works on other computers), but all the other times the USB flash memory didn't even show up in Nautilus.
I am no techie so I'm not sure how to check what the problem is here. I've been googling it but either it refers to some specific stuff that doesn't cover my case or it simply is too technical for average users like me to understand.

For Linux command sort, how do I force sort to load all input into memory and sort assuming I have enough memory? Or is it best to use a RAMDISK to store the input before feeding it to sort?

I'm running a java program and to debug the program instead of using a debugger I would like to look to the heap and to the bytes in the memory of the process. I was hoping that the pointers would give me a snapshot of a moment of the application. It exists a program that allow us to look to the details of a process and to the memory ram?

I have a mxn matric (which is my simplified way of saying it is RAM with bytes on it) Some of the locations on this metric is filled with some data and some places are empty. The mxn are very big numbers in size. I am trying to make a program so that if a system call wants to write some thing on empty locations on this mxn metric it should be able to do so without any problem. The thing which I want to understand or logic of a data structure is what data structure do you people feel should I be maintaining so that I can allocate the requested space immediately from the above mxn matric when some system call requests for some (k) number of locations from above metrics.
The logic initially I thought was to maintain a hashtable
1bytes requested----------> location 1,location 2,location 3.........location n
2bytes requested----------> location 1,location 2,location 3.........location n
3bytes requested----------> location 1,location 2,location 3.........location n
[code]....
but the problem with above logic is size of the pointers where I will be writing this problem is unsigned 64 byte.So to know location of one free byte if I am maintaining one pointer of type u64 this is not a feasible solution.

Okay so I made a mistake and I have to reinstall Linux (see: http://ubuntuforums.org/showthread.php?t=1602329)
Since I can no longer boot to my existing installation (the graphical version OR the text version), I am having trouble saving off what I don't want to lose.
Can I boot from the CD and get to my stuff through there? I am in the CD version of Mint right now (posting this) and I cannot navigate to /home/myusername/ (obviously). So where would I find those files?
Do I have to mount that partition or something? It looks like a lot of my stuff is mounted already in this CD version... which worries me.
An alternative is that I still have Windows 7 installed that I can boot to if needed. If thats a way to extract my files I am all for it.

I have a second hard drive in my desktop and both the main dirve and second drive are 250GB. I use the second drive for backups, both manual and using back in time. The other day I noticed that the second drive was formated in FAT32. If I go to disk utility and look at the drive it says:Usage:FilesystemPartition Type:Linux (0x83)Type:FAT(32-bit version)Is this ok? I thought in Linux it should be Ext4. So far its been working fine for a while now but if I need to move my files and re format it to ext4 and move them back I would rather do it now when there is less data on the drive.

I decided to remove my Kubuntu partition until I can fully dedicate my time to figuring out linux (right now I need Windows for certain things, i.e. flash and my zune).
I fixed the MBR, but the problem now is I have a 142.77 GB partition of free space. What do I do? Do I just delete it?
When I click delete this is the message I get:
"This is an Extended partition. This partition will become inaccessable if you delete it. Are you sure you want to delete this partition?"
I am essentially asking if this just means the partition will be gone and not the memory, and where the memory goes if I delete the partition.

A friend of mine asked me to try and recover some photos she deleted by accident on her SD memory card. Normally, I would flip over to my Windows box and do this, but I'm wondering if there is a Linux equivalent to a Windows data recovery program. I'm running Fedora 10.

Using 10.04 Netbook version. I am finding on my Asus EEE 901 that sometimes file copy just seems to freeze - seems to happen usually when copying from the built-in SSD memory to the plug-in SDHC memory card. I have tried reformatting the card and using a different card. It is not just this computer since I found the same thing on my last Asus which was the 900 model.
I am told that there are issues with Nautilus. Is there anything which can be done to improve this or is there anything else which I can install besides Nautilus? I am assuming that there is some issue related to Ubuntu's handling of SDHC memory cards.
It is becoming annoying because it seems to work sometimes and then not. When it happens only option seems to be to turn the netbook off and on again. Even if the file copy is cancelled the card seems to be unaccesible until rebooted.
Also after a certain point it seems that when I try and copy new files to the card, they appear to copy ok but obviously are corrupt in some way - when you try to play videos for instance they are faulty.

Back in Febuary, my wife bought a Toshiba Satilite from Wal-Mart and a few days ago the hard drive got toasted. So now I'm using an 8gig usb drive as the boot drive. I also have 2 other flash drives for downloads and such but overall I am very pleased.
I'm running 11.04 32 bit and was wandering if 64 bit made a difference. I've got 4 gigs of ddr3. It's slow to boot, but once it's running, it's faster then Windows 7. Very nice.
Is there anything I should chage, use, since I'm running it off a flash drive??
I have 3 seperat drives, 2 x 16 gigs and an 8 gig, and was wandering which one would be best for booting off of? What do I look for??
Here's what I got:
00:00.0 Host bridge: Advanced Micro Devices [AMD] RS880 Host Bridge
00:01.0 PCI bridge: Toshiba America Info Systems Device 9602
00:06.0 PCI bridge: Advanced Micro Devices [AMD] RS780 PCI to PCI bridge (PCIE port 2)
[Code]....

So I am working on a clients PC, and after I saved their data on an external hard drive I left it plugged in while I reinstalled Windows for them.....I HATE Windows. Stupid OS doesnt know any better than to just go deleting everything. Ubuntu would have known better than to delete multiple hard drives like that.
Anyway, please tell me I can salvage this data for my client? It was probably just reformatted. The data should still be there right?

I have a problem I don't know how to solve. Today I bought a netbook and while waiting for the new Ubuntu Unity release to come out, I thought of trying out Crunchbang instead of Windows that came with it. Browsing on my Ubuntu desktop machine, I found a guide for making Crunchbang live USB stick, and i followed the procedure. However, I made a very stupid mistake. The guide said I should enter the command:
sudo dd if=/path/to/iso/crunchbang-10-alpha-01-openbox-i686.iso of=/dev/sdX bs=4M;sync
where "of=...." part should be replaced with the name of the HDD. I forgot that I have an external HDD mounted and mistakenly copied the data to it.
After this, I cannot see the content of my external HDD anymore. Instead, i have this 620mb large Crunchbang-install device.
I know what I did was stupid, but is there a way to get the content of my HDD back? I have some valuable data on it.
