General :: Deleting Hidden Partitions On USB Drive
Feb 19, 2010
I recently bought a Buffalo 500GB ministation usb with "optional disk encryption". Turns out, I'm having one hell of a time trying to remove the "optional" from the drive. I figured I could just delete the program that is on the disk, and go on my way. That doesn't seem to be the case.
fdisk /dev/sdc1, then "p" showed that there were 4 partitions. So I deleted them one by one. "n" gave me a new partition. "t" I used 87 because I will be using it on windows. Then "w" to write everything.
mkfs -t ntfs /dev/sdc1 - all went well.
fsck -f -y /dev/sdc1 - all went well
Then I took the removed the drive and plugged into Windows only to find that the "optional" is still there. It actually creates a virtual drive with the "optional" software. So I tried it over again. I tried fdisk only to see that the partitions were back (as if they were never removed). I removed them again, and used primary partition as linux and wrote to disk. As a hunch, I checked permissions. Can't remember what it said, but I did change them.
chmod 777 /dev/sdc1
Then in a last hope of desperation, before coming to work today, I decided to dd the drive.
dd if=/dev/zero of=/dev/sdc1 bs=4k conv=notrunc
Is it possible that the "optional" stuff is actually hard coded onto a chip, or something inside the drive and I may never get rid of it?

I have a laptop that I was dual booting with Windows 7 and Ubuntu. I used the MSFT disk manager to delete the partitions. I made sure my windows live cd was working, which it was, before doing this. But now, when I boot my computer, it won't run the cd. All I get is
error: no such partition. and then a command prompt: grub rescue>
I made sure my boot priority was set to boot from the CD first.

I have a Huawei IDEOS S7 android tablet running 2.1.My USB port has died, so I need to delete a partition I put on the internal memory area, then resize the remaining partition back to the full amount. It looks like I should be able to use terminal emulator to do that, but I don't know any of the commands.

I have Intel Pentium3 motherboard model 845GVSR with 40 GB Hard Drive, DVD/CD ROM and 4 USB slots but no Floppy Drive.My PC was working fine until I deleted the contents of hard drive accidentally using trial version of killer software.I ried to install Linux by making a boot-able CD, but it did not work.Then i tried to make a boot-able USB using Universal Notebook Installer, it did not work either. I just get the Error " Error loading operating system.Then I tried a free software from net by the name James Format Tools - DOS on USB. Using this computer did boot but DOS did not install and I got the error message "invalid drive specification".I understand that now I will have to write boot sector afresh and will have to Format the hard drive,, but how to do this as all my attempts to get to the hard drive failed

When I was installing Ubuntu onto my laptop, I probably did a mistake partitioning the hard drive by selecting align to: nothing, because I didn't want to have unallocated spaces between partitions. However, this resulted in partitions' misalignment as no one partition in the extended one (including the one that is extended) doesn't start on a physical sector boundary. As I already have much data on the HDD and I don't have another one that big, it is impossible for me to erase existing partitions and then copy the data back. So, is there please a way to get the partitions aligned properly without deleting them?
Here is output from fdisk -lu:
Disk /dev/sda: 750.2 GB, 750156374016 bytes
255 heads, 63 sectors/track, 91201 cylinders, total 1465149168 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes
Disk identifier: 0xd58c6e9d

I have what I thought was a simple task of creating ISO images of my Windows 7 system partion and boot partiton (the C drive) on my physical hard drive that I could use to load Windows 7 onto a virtual machine. Anyway, I'm running Ubuntu off the CD drive and I can see my drive partions (checked using the fdisk -l command). I have tried many iterations of the mkisofs command, but no matter what I do I get the error message: unable to open disk image file 'dev/sdb/win7sys.iso'. I don't understand why it's trying to open an ISO file it is supposed to be creating. The -o FILE option sets the output file name, so the message makes no sense to me. Below is an example of a simple and longer version with more options that I have tried to create an image of my sytem partiton (sda1) and save it on an external drive (sdb) with the file name: win7sys.iso (the next step I think would be to create or merge both partition images as one iso file for the VM). But I can't get past this error.
Can anybody tell me what I'm doing wrong?
sudo mkisofs -o dev/sdb/win7sys.iso /dev/sda1
sudo sudo mkisofs -input-charset iso8859-1 -V win7sys -o dev/sdb/win7sys.iso /dev/sda1
* Note that the output after the -o parameter is the desired destination /dev/sdb (my external drive) for the image file and /dev/sda1 is my Windows 7 system or boot partition (sda2 is what Windows sees as the C drive).

I was installing Linux Debian on a machine and my usb external drive (320 GB) was attached with it (It was on NTFS that time). During installation I deleted all the partitions from machine and from my external drive. Can I recover the data from this drive?

I am doing major deployment of opensuse 313 pcs from windows to opensuse. I am having a problem that I have to keep 2 ntfs partitions intact will deleting the partition that has windows. Now everything goes well, opensuse installs but the problem is that I cannot give user full rights to ntfs folders. I have used graphical file permission methods n terminal chown n chmod methos but still permissions revert back to root.

My home server runs Debian Lenny, and I'm about to upgrade the system drive to a larger drive.In the process, I want to take the opportunity to reorganize the partitions and resize them. For learning purposes, I'm planning to migrate from an MBR partition table to GPT.Because of those two changes, I can't just run "dd if=/old/drive of=/new/drive" (well, not without lots more work afterwards). I could use the debootstrap process to get a fresh installation on the new system drive, but I used that technique during the last system upgrade and it's probably overkill for this.Can I just copy the partitions from the old drive to the new?Will "dd if=/dev/hda1 of=/dev/hdb2" work, assuming /dev/hdb2 is larger than /dev/hda1? (If so, the filesystem can be resized to take advantage of the new larger partition, right?)Would parted (or gparted) be a better tool for copying the contents of the partitions?

I have recently reformatted my external hard disk to ext3, and now whenever I delete something via my file manager, a hidden directory (".Trash-1000") is made. I would like to keep this drive clean, is there any way to stop the directory from being made? I'm getting annoyed having to rm -r it every time I delete something.

I have stumbled upon a rather peculiar problem whilst trying to rescue a CentOS system. For this effort I have to connect a USB stick and boot from that stick. That does not pose a problem. The system contains 3 disks (scsi) which are, not surprisingly, found as sda, sdb and sdc. The problem is that the USB stick is also assigned as 'sdc'. And so the process comes to a grinding halt, because there is no image found on sdc.
I have to find means to make usb-storage (or whichever module decides on using sdc for the USB stick) choose sdd as devicename. But how?
I did a pretty extensive search through the forums, but to no effect. Probably because I did not really know how to construct the finding key for this specific problem.
Bonus points for one that incorporates the fact that this system is at a remote site on which I login via a network connected KVM...

Ok so basically this isn't my harddrive but hear me out. It's a known issue but it only happened after him downloading stuff off priate bay. The harddrive is not detected on BIOS, so you can't boot through it, just the CD Drive is now detected. You can't use SAFE mode as it reverts to another issue, a black screen with a white cursor, no keyboard commands work.
No restoring disks will fix it nor master disks, it's literally a bad *** issue. Thou I can still load things via CD Drive so I used the Acronis Bootable Media and surely enough, it could anaylse data on the harddrives. I thought maybe i'll try PE Bart but once again, loads up to Black screen with White Cursor. So I put in Ubuntu and yes, I can get on the GUI, but I can't install the operating system.
There would always been an issue. something about in/out whilst installing but as long a I can use the tools, then we go onto Disk Utility. When I try to format, the Error Message apprears stating : Eroor creating File System: helped exited with error code 1: Error calling fsync(2) on /dev/sda2: Input/Output error. This would be the same error i would get via installing and I would have to ignore and eventually whilst installing, from being complete on the right hand side, it would say ERROR or ABORTED after 70,000.

When I delete files from my usb flash drive on my Karmic laptop (press del key), the properties of the drive remain unchanged (available space/used space). It looks like the files/folders have been deleted, but when I go to my windows machines, the files and folders are now in a folder marked "Trash".Am I missing a step when attempting to delete the information when connected to my ubuntu laptop?

My trash won't delete and it is causing me to not be able to use my flashdrive. When I tell my trash to empty it will either say it will but the files will still be there or it will say a can't b/c i didn't delete it from my trash(screenshot). I don't know what to do to get it to get rid of the files since I tried telling it to bypass the trash and that didn't do anything.

I had to recently reinstall ubuntu because 10.04 started acting up on me. I reinstalled 9.04 but I don't know how to mount my RAID drive without messing with the data that's already on there. I have the UUID for the RAID but fstab isn't able to find it. I also previously used RAID software but I don't remember which one I used. how to mount my drive so that ubuntu can see it?

just a general weirdness, but some folders that are in my /home folder don't show up. if i check "show hidden folders", they still don't show up. for all terms and purposes, they are simply not there. however, if i search for them through the search tool, or beagle, they show up as being in my /home folder. so, anyone have any idea how this happened, or how i can remedy this?

Since August of 2009 I have been under attack by corporate Black Hats. I found a 105GB FAT16 Hidden partition on my hard drive. Seventy four percent full (78GB). What led me to this was the fact that I couldn't help but notice that my Internet connection was a revolving door that never stopped spinning. So I went looking for why.
I removed the hidden flag, and patched the partition, but couldn't open that thing no matter what I did. I tried for a month. The attacks started as soon as I stopped these guys from accessing that data. At this point we are 9 months into 24/7 attacks. I have interviewed with the FBI, and local law enforcement, but they are intent on making me out to be a conspiracy nut. I am not at all. All they wanted to do is quiz me on my computer skills. If I managed to draw the attention of a corporate security group they killed it.
I am a US Navy trained Electronics Technician. 58 years old with ECM experience. I have been doing both bench, and field service on all manner of electronics for 40 years. My last job was supporting field engineers, and technicians for Samsung Electronics of America. The attacks have spread to my mother, and best friend. My phones are bugged internally at the phone company, and my modem has had its firmware altered to call them. They run around inside my ISP like they own the place.

I decided to swap my existing small hard drive for a bigger one which went well. Then I formatted the old drive using a windows vista machine before putting it on my spares shelf. To my amazement after formatting my 20GB hard drive had become an 8GB hard drive. I fear the worst but remember that Ubuntu put a large swap file on the drive and wonder if Vista has just ignored the system partition. I tried attaching it to my Ubuntu laptop which reports a healthy 8GB hard drive even after formatting again. I don't know enough about Ubuntu to try repartitioning it in that so I tried DSKCHK in windows which reported a healthy 8 GB hard drive. Is all hope lost or is it a "hidden" partition which might be recovered under Ubuntu? If so, how?

So I recently got a WD MyPassport external hdd with 500gb capacity. I formatted it to NTFS so that it would be more efficient transferring data between my Ubuntu and Win7 dual boot. But now I want know if it is possible for me to create a 100gb FAT32 partition on the external without destroying the data on it.

Is there any way to Merge hard drive partitions? I didn't really know what I was doing during install and wound up leaving myself with over 100GB of unallocated hard drive space. if I create a new partition out of this, could I possibly merge it with another? and if I do, should I merge it with root or home? I am using 10.10, by the way.

I have 2 500gb drives in my system. One of the drives I use for swap and home is failing, good thing it is under warranty... Bad thing I have to remove the drive from my system.
I have / on the first drive taking it all up. On the drive that needs replaced I have /swap and /home taking up the whole drive.
Is there a way to shrink /dev/sda to put swap and home on that drive and to move it back when new drive arrives? Or would it be simpler to just re-install to one drive?

I have this rather old Compaq Presario 2184 (Celeron processor), with a completely busted optical drive - which means I cant boot from Live CD, and it doesn't boot from USB, either... which means I cant use a live memory stick, either. It's currently running Xubuntu 9.04.
I'm seriously running short of space on my root partition - can't upgrade to 9.10...
I had a Windoze partiion that I decided to remove, using Gparted. Identified the NTFS partition, right click, delete. After that, I couldn't do anything else... I then found this page, that told me that I cant resize all partitions while booting from hard drive, and that I needed a Live CD. For the reasons mentioned above, that's just not possible...
Are there any alternatives that the good folks here can suggest? For example, can I create a new partition, and move my entire /usr there? It would solve the space problem, but I'm not confident of doing it without screwing up something... could someone kindly guide me through the process?

When we install a linux OS, we've an option to create partitions. In my laptop I've create partition for /opt, /home, / and /tmp. Are these partitions the same type of partitions as the partitions created by LVM?

My laptop has 80GB HDD Space, and sometime ago I installed fedora 13 inside windows with 15 gb space for it. Now, I have removed windows and the disk space is recovered. So the disk space is split up like this. 15GB for Linux + 42GB + 21 GB. I just want to know whether I can extend this 15gb so that the full of 80GB can be used without having to mount it. Or in other words can I remove the partition and make it into one single drive.

I've had many installation issues that I won't go into here, and have had to reinstall several times. All I'm trying to do is get an XP installation dual-booting with 9.10.
1. My hard drive partitions are:
120 GB NTFS (with boot flag) for Windows
40GB EXT4 for 9.10 (/)
8GB Swap
The rest (around 220GB) EXT3 for /home
2. I install Windows, and during the windows partitioner it doesn't see the 3 other partitions on the drive, just the NTFS partition, which is odd. I install Windows on that partition, and confirm that I am able to do a cold boot into it.
3. I boot up a 9.10 CD, and all looks as it should. I install Ubuntu in the partitions as outlined above, and it doesn't have any issues.
4. I can now reboot into Ubuntu without issue. When booting into Windows, I get the startup screen with the blue "progress" ticker, which displays for about 2 seconds, then I get a BSOD. The message refers to making sure the hard drives are "partitioned and terminated correctly" and whatnot. If I didn't know any better (and I obviously don't), I'd accuse Ubuntu of bjorking my clean Windows install.
