32 gb micro sdhc card corrupt, "unknown partition table"
location: ubuntuforums.com - date: April 12, 2011
I recently received a 32gb micro sdhc card for storing music on my phone. I first formatted the card on my phone for use with it's music player. Then I inserted the card into my computer's sd slot. I began to copy music to the card, but it froze during a file sample. I couldn't force quit the process, so I shut down ubuntu thinking I'll reformat the card and start again. Something went wrong with the card and I don't know what to do about it.
My phone won't recognize the card like it did before. It behaves as if there is no card.
Windows shows the card, but when I try to format it in Windows, it gives me an error; something like "windows could not format the drive"
Here is what I get from dmesg:
[ 215.780234] mmc0: new SD card at address 0001
[ 215.780490] mmcblk0: mmc0:0001 AF HM 8.00 MiB
[ 215.780616] mmcblk0: unknown partition table
please don't hesitate to ask for any more information.

I was using my pen drive to copy some files from a computer using Ubuntu and without any reason the computer crashed, i turned it of and took off the usb drive. from that day until now i can't open the USB drive, windows tells me i have to format the pen, and 1 sec later tells me "Windows can't format the drive" or something. Linux tells me it can't mount the drive.
I open the terminal and i wrote
tail -f /var/log/messages
when i plug in the pen drive it says:

USB Flash Unknown Partition Table Logical Sector Size is zero

A friends USB device screwed up and now I am struggling with data recovery on this 2GB USB device (M-Systems Flash). The device can not be mounted (Key messages: "unknown partition table" and "Logical Sector Size is zero"). I already tried to backup an image on harddisk and replace the 1st sector by the 6th sector (because this is supposed to be the backup sector) using dd utility, unfortunately without success. The commands I used:

Unknown partition table

I've got a Maxtor 5T060H6 60gB drive with 3 fat32 partition. And Redhat8.0 is installed on a Maxtor 5T020H2 20 gB drive. But can't read the partition table from the 60gB drive.
When I install Redhat 7.2 it can read the partition table from that drive.
Does anybody know what's wrong?
Ubuntu Ultimate Edition 1.4 Misreads Partition Table
location: linuxquestions.com - date: July 12, 2007
I recently tried out Ubuntu Ultimate Edition 1.4 with Live Cd. I loved it, and it helped me remember what drew me to Ubuntu. Now the problem is installing it to my drive. I already have existing partitions, and I want to install ubuntu without disrupting anything. The problem is that the installation software reads my drive as empty; all unallocated. The weird thing is that I am able to mount my existing partitions without trouble; within this live distro.
the kernel failed to reread the partition table

Today I decided to completely removed my windows partition and the secret windows restore partition. (just not using windows any more - despite having expensive software on that partition) Well, in my naivety i used Disk Utility typing 'sudo palimpsest' to unmount the drive and tried to turn it in to a ext4 partition so I could store stuff on it. Unfortuantly it just kind of unmounted it.
After some forum searching I gave up on Disc Utility and tried using GParted. Here is
my current predicament:
The unallocated is just dev\sda1 after I tried to delete it, but I still cannot format the unallocated partition as it thinks it is busy: here is my drive info and the error from my terminal:

Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes

I have one hard disk (call her HDA) that contains nothing but a single ext4 partition containing a backup of all my important data. Last night I did a clean install of Ubuntu 10.10 on my primary hard disk (call her HDB) and from there proceeded to upgrade directly to Ubuntu 11.04 upgrade. In 10.10, I was able to read HDA just fine. However after the upgrade, I can no longer mount this drive.

I am currently running CentOS 6.x on my primary workstation. I want to replace CentOS with Ubuntu after I found that Ubuntu has better driver support and software repositories.
I booted up my workstation with the latest Ubuntu 12.10 Live to test and see if Ubuntu will recognize my CentOS encrypted luks container and determine whether or not I can replace CentOS with Ubuntu. My system root and home partitions are logical volumes stored in a luks container that was originally created with Red Hat's Partitioning Tool.
I discovered that Ubuntu's Partitioning Tool does not recognize Red Hat's encrypted luks container and will not allow Ubuntu to be installed onto an existing logical volume. Instead of recognizing Red Hat's partition scheme, Ubuntu's Partitioning Tool tried to recalculate the luks container as "free space". I clicked "revert", but to no avail - the Ubuntu installer had already trashed my partition table. I then clicked "quit" to exit out of t
