General :: Multiple Distros - One Data Partition - External Drive

Apr 8, 2010

I've got an external hard drive with one large data partition on it. I also have four computers to connect it to (individually, not at the same time). Three machines are running Slackware and one is running Ubuntu 9.10. I need to be able to just plug the drive into whichever machine, mount it (preferably to the same location each time) and not have to worry about user permissions and such. Do I just chmod 777 all the files and folders or is there a better method for different 'users' to access the same partition? And how about mounting to the same location each time?

Now the second part of my question I'm pretty sure I'm not able to do but just in case..... is there any way to encrypt the information safely and make it compatible with a Windows XP machine?

Software :: Install Multiple Distros On An External Drive?

Jan 22, 2011

I am trying to intall multiple distros on an external drive. This drive has no windows installed and I want it solely for Linux use.
When installing the distros from live disks, each time it comes to selecting the partition to install to, I am asked for a mount point. I have used in the first installation but this cannot be used again.

General :: Encrypting A Common Data Partition Between Distros?

Aug 6, 2010

On my laptop (Dell Studio 1745) w/500GB HD, I have a common data partition shared by openSUSE. Fedora, FreeBSD, and windoze 7 currently. I would like to encrypt this partition (/Common) and have it accessible from all distros either with a passphrase key in /root or on a flash key. I've been researching on the web and there seem to be several possibilities using eCryptfs, Luks, cryptosetup, or any of several methods.

My question is, what have people here used and how well did it work? Also, what was required for setup (I'll probably have to explain/teach it to my wife who is technology challenged-but I still love her anyway) and my daughter who's just getting into linux. I would like to be able to keep the entire directory on the hard drive but also have the ability to copy it to external USB device for transport.

Installation :: Multibooting Multiple Distros With A Separate / Boot Partition For GRUB

Mar 27, 2010

Noobish question on multibooting multiple Linux distros. I have four of the current major Linux distributions. Each has been installed and run individually (no other Linux distribution installed) in a dual-boot configuration with Windoze. No problem.

What I want to do is install all four Linux distributions and multiboot them. Reading the internet it would seem this is a simple task with GRUB. The short version being - install a Linux distro with a separate /boot partition for GRUB and use GRUB to boot the other Linux distros from the GRUB boot menu.

So I installed one of the Linux distros with a separate partition for /boot. The distro installer installed GRUB in /boot and correctly setup a dual-boot configuration with Windoze. GRUB was installed to the MBR. Next I installed a second Linux distro in its own root partition and told the distros installer NOT to install GRUB to the MBR, but rather, to the boot sector of the root partion of the second Linux distro. Installation was uneventful (and I could access the second Linux partition from the first installed Linux distro, things looked ok). Then I added to following to the installed (MBR - /boot) GRUB's menu.lst:

Code: title lixux distro 2
root (hd0,7)

chainloader +1 After which I rebooted the system and the new entry for the second Linux distro now appears in the GRUB boot menu. I selected the second Linux distro from the boot menu and got the following GRUB error: Error 5 : Partition table invalid or corrupt

General :: Possible To Mount USB External Drive As R/W For Multiple Users

Jan 12, 2010

I would like to mount a (permanently) attached external USB drive so that it is writable by multiple userids. Currently HAL is mounting the drive as writable to my owner user and readable for group and others. My m/c also runs as an FTP server and I would like said FTP server to be able to write files to the external drive. Just being able to specify a gid would probably do the job for me.

I have googled HAL and UDEV and also attempted to configure usbmount to do this, all to no avail. I am running SLES 10.3. So in summary, can I & how do I either make HAL mount the drive with gid=nnn, or should I not use HAL and simply make an entry in /etc/fstab and make sure a I get the same device address for this USB drive each time I boot?

General :: Resize Partition On External Drive

Mar 21, 2009

Computer hardware is not my bag. I accidentally installed ubuntu on external F drive, thinking it was C drive, unaware that ubuntu installs on drive with most available space. Installation involved partitioning the drive in about half. So, before I install it on C drive, I want to restore my F drive. I deleted partition using XP Disk Management tool and tried to use gParted on Parted Magic live boot cd to resize remaining partition that contains my data. But it doesn't seem able to expand the good partition to reclaim the 'unallocated' space. How do I accomplish this? Must I backup and reformat?

General :: IMac Boot From Partition On External Drive?

Apr 3, 2011

I have the following "setup:"

iMac (no internal drive/dead) --------- (Firewire) ------- [[MAC OS X]]
|
|
|[code]...

I routinely use the firewire drive to boot MAC OS X.However, I would like to boot from the linux partition of the USB drive. This linux partition had linux installed on it from a live cd, and during that process, I told the installer to install GRUB on the usb drive (which happened to be /dev/sdd).My question is, how do I get this disk to show up during the iMac option-boot? Currently, only the firewire MAC OS X option shows up. I have read about rEFIT, but that appears to install it to the Mac OS X disk (would that still work?)...Also mentioned was installing rEFIT to the internal EFI system partition, but I don't know if that is wise.

General :: Sharing An Ext3/ext4 Partition On External Drive?

Aug 30, 2011

is there a way of sharing an ext3/ext4 formatted partition on an external USB drive between different users (uids) on different Linux machines without creating a group for this purpose, setting the group ownership of the partition to this group and adding each respective user to the group on every machine?This would mean that I need to have root privileges on every machine... which I may not have in some cases.I'm using the partition to store the code I'm developing on Linux and I would like the option to be safe... if possible.I could use a vfat partition but then I have no control of the rw rights + I cannot develop directly in the dir: I would always have to tar.gz the directory, extract, work, tar.gz, copy to the external drive.

General :: Missing Partition After Installing Ubuntu On External Drive?

I am keen to start using Ubuntu and have installed it on one of 4 partitions on my new 1 TB external HD. I got to the reboot stage where I was expecting a new boot screen where I could decide to use either XP or Ubuntu. But there is no mention of Ubuntu just XP and the volume I installed Ubuntu on has disappeared. I can find the other 3 volumes on My Computer.

General :: Installing Multiple Distros On One Hd

Jan 19, 2010

I want to install multiple distros on one hd just to get some experience with them. I'm wanting to try out different distros and DE's, so I think I'm settled on wanting to install Ubuntu, Mandriva (or PCLOS), opensuse, and Linux Mint, all on a 40GB drive, giving a little more than 10GB to one of them to use as my primary Linux OS. I also have a current XP install on another hard drive that I'd want to leave connected so GRUB will detect it (not touching it at all during OS installs).

After trying several times to get 4 (or even 3) OS' installed on one drive using one GRUB has been a pain, so it looks like I'll have to put each OS' GRUB on it's respective partition and use one OS' GRUB as a primary in the MBR. With all that being said:

1. What's the best GRUB to use? Much difference between Ubuntu 9.10's and Mint 8's?

2. I'm not worried about saving data on a separate /home partition, so could I use one swap partition and a / root for each OS (giving each one about 10GB)? Would that just mean resizing the previous install's partition and manually creating a 10GB / ?

3. I've read the GRUB 2 guide several times, and when manually adding all of the GRUB's in different partitions to the "main" GRUB, all I need to enter is the title, root entry, and possibly chainloader +1?? This is the area I need the most help in... manually adding entries to GRUB 2... not too worried about Windows because that's usually detected, just adding other distros.

General :: Where Does ITunes Store Its Stuff - Copy Its Data Store To An External Drive

Dec 8, 2009

I have two students whose windows laptops are riddled with malware and not working properly. They want me to help them install Linux (which we use in school), but they are concerned about their iTunes.

Having avoided iPods as "defective by design", I know nothing about iTunes whatsoever. However I remember reading about DRM locking and such problems that have me concerned that I won't be able to do it.

Where does iTunes store its stuff?

Can I copy its data store to an external drive, and then into a linux home?

Then will it work on wine, or can another manager (rhythmbox etc) access the itunes data?

Alternatively, if I partition the drive and install linux, can rythmbox/wine/something access itunes data on the win partition?

Supposing they are buying music through iTunes, what will happen to that account?

Finally, one of them has an iphone. Does that work with linux?

Ironic that an apple application is blocking migration away from windows.

May 16, 2010

I'm running 10.04 X86_64. I have this 650 GB External Hard Drive With three partitions: one fat32 and two ext4. Sometimes when I plug the drive in X crashes. I get no response at all from the keyboard but the pointer works. I am able to minimize and maximize windows but i cant close them and i cant click on the top bar. Today the error occurred after I transfered some files from one of the ext4 partitions to a 320 GB External HD(single partition FAT32). I pressed the ctrl + alt+ f1 ( to go to the shell :-/) and this strange lines of code where showing up over and over again:

[XXXXX.XXXXXX] ata1.00:status: {DRDY ERR}

Also the following exception:

[XXXXX.XXXXXX] ata1.00:status: Exception Emask 0x00 SAct 0x0 SErr 0x0 action 0x0

When i came back to X (ctrl + alt + f7) and unmounted the drives every worked fine.

OpenSUSE Install :: Altered Partition On An External Disk - Can Recover The Data

Aug 28, 2010

I have a 250 GB external disk, where there was store a hundred and something GB of data. Pictures, music, documents and TV-shows. It was FAT32. In an attemt to make an live USB drive with openSUSE, I did exactly what I shoulden't do: I mistook the external disk for the the USB drive. Now the external disk has a 700 mb linux partition, while 232.2 GB is unpartitioned. TestDisk from CGSecurity is looking to see if there is a lost partition table there, somewhere. Is there anything I can do? There was no formating, so the data is still there (except for those 650 mb that was overwritten). Is there any way to rebuild the old partition?

Output from "fdisk -l":

Disk /dev/sdc: 250.1 GB, 250059350016 bytes
64 heads, 32 sectors/track, 238475 cylinders

Ubuntu :: Sharing External NTFS Drive Across Multiple Users?

May 26, 2010

I have an external USB hard drive at /dev/sdb1 (NTFS)

2 users: johnny, audio

for some reason this drive is mounted at /media/TREKSTOR_ with johnny as the owner. I can't seem to chown the drive to audio. If I unmount the device, and remount it, the owner is set to johnny again. I need to access this drive from the audio account.It's a 1TB drive, so I wouldn't be able to reformat it to EXT3 easily as it's almost 60% full.

General :: Two Distros With The Same /home Partition?

Oct 11, 2010

I am running Ubuntu with root on one partition and /home on another. I am proposing adding another distro (probably openSUSE) with its root on a partition which is unused at present, and the same /home partition as Ubuntu. Will using the same /home partition for two distros work? I realise that I will have to use the same usernames and passwords for both.

Debian Configuration :: Multiple Partition Setups Other Than Resistance To Data Loss In Crashes?

Feb 25, 2010

What are the advantages of the multiple partition setups other than resistance to data loss in crashes? Is there any other reason to have a special partition just for your boot directory (kernel files and config) than surviving a major crash?

Also, is it possible to make the Debian installer accept an existing set of partitions? Or even alter the size of the automatically created partitions? Does expert mode let you control the partitions? How many other very detailed things would I have to know to use expert mode, though?

OpenSUSE Hardware :: Restoring Data From A External WD Elements Hard Drive?

May 29, 2011

(Just to clarify: This has nothing to do with the 11.4 mount problem with external NTFS drives that is stickied in this forum.)

I have this 2 year old WD Elements drive (500GB) that is NTFS formatted and that I've used for backup all this time, until a few months ago it failed to be recognized by any computer. The power supply is working, so I first requested a new cable, which didn't help, and now I received a replacement. But still I would like to save some of the data on the hard disc. I need to have this figured out within this week as I have to return the old drive, or they will charge me for the new.

So far, the only software to still recognize the drive was a WD analytical tool for Windows. It didn't find any problems or show any error messages as far as I could tell. They recommended using testdisk to recover the data, but testdisk doesn't recognize the hard drive in the first place. I also tried KParted, but no success.
