Ubuntu :: Which File System Use For External HDD
Aug 29, 2010
I just picked up a 1 TB Western Digital. Right now i just have Ubuntu 10.04 installed but I think I will need to dual boot with winblows soon for school. Which file system will play nice with both OS's? Should I try to put one of the OS's on the external HDD or install them both on the internal (250 GB Seagate)?

I have a 1.5TB Western Digital Caviar Green in a USB 2.0 external setup with an ext4 file system. I'm going to purchase a 2.0TB Western Digital Caviar Green in a USB 2.0 external case, copy the data over and put my 1.5TB in a fire-resistant box in another house. I'm worried about a couple things however:
(1) I'm worried about the long-term viability of _any_ file system years into the future. I've been storing my data on hard drives (instead of CDs, DVDs or BDs) for years now due to their higher reliability than optical disks. However, the file system used in optical disks is UDF which I think has much longer viability into the future. I'm not going to store terabytes of data on optical discs of course, so I'm wondering what I should choose for a hard drive file system. FAT32 or NTFS (due to Windows' 90%+ presence on the desktop, including still being used by Windows 7) may be the best choice, but I much rather have a open source file system, especially one that allows for permissions, timestamps, etc.
(2) As for my 2TB hard drive that I will be using for a while into the future, should I continue to use ext4 (I've had no problem with it thus far), but is there another file system that has better performance when storing and transferring gigs of data?

Got Samba on fedora 13. Windows machines backup their files to the linux shared folder. I want to attach an external hard disk (USB) to the linux machine in order to backup those files. Can the external hard drive be NTFS or do I need to reformat it as Linux file system (ext3)?

I'm going to reformat my external drives to get rid of the crud that I've built up. (Crud being incremental backups, windows software, and similar things.)(I also want to get rid of the FAT32 file system that they use.) These are USB 1TB drives. The theory is that data is written to it once, but read back a number of times. (I also burn that data to DVD. If there was software that could organize 5TB of data on DVDs, I'd be using them.)
I"m trying to decide whether to use ReiserFS, Ext4, or another file system. Basically, I want something that:
* Won't get corrupted when the power fails;
* Can handle files that are 4+GB in size;
* Uses extends --- preferably without user intervention;

Assume I have plugged in an external USB hard disc.
How can I find out (from terminal cmdline) the file system (ext2, ext3, reiserfs,...) of this hard disc?
From Ubuntu I know the two commands:
sudo blkid -c /dev/null
or
sudo fdisk -l
but these are not known in CentOS.
What are the corresponding cmds in CentOS?

i needed to change my external hard drive's file system from ext3 to fat32, to use it in windows, which i did the simple way: i shrunk the ext3 partition, made a fat32 partition, copied the files over, removed the ext3 and made the fat32 bigger. unfortunately, while gparted was making the partition larger, my computer shut down. i lost all my files and the partition messed up immediately. i made a new fat32 partition, after deleting the old one, but noticed that gparted was showing 100 gigs already in use (???). so now i have a 300 gb hard drive with only 200 gb i can use; i ran df to make sure gparted wasn't messing up, but indeed it shows the partition as being only 200 gigs in size. i haven't tried making any other kind of partition yet, such as ext3, for fear of losing my files again, and because it wouldn't be permanent anyway, because i need those files in windows and stupid microsoft won't make their OS ext3 compatible.

It started when I wanted to dual boot Windows 7 and Opensuse off of my netbook (No DVD/CD drive) I tried install suse from an external hard drive and I botched it. I ended up erasing EVERYTHING off of my internal netbook hard drive. Windows and all.
Well, I had a couple of other computers so I studied up and eventually successfully installed OpenSUSE 11.2 on my external hard drive (11.3 being the one that I accidentally erased everything with, so kinda scared of it) and now I want to install openSUSE 11.2 on my internal netbook hard drive.
I can not use disks
I can not use a flash drive (For some reason, even if I make it bootable, it will not load up, this could be because it's actually a 8GB microSD card that is placed in a USB card reader.)
I can not use an external hard drive because that's what I'm running suse off of.
I've tried reading up on how to install suse on another drive off of the hard drive and I've gotten as far as whenever I boot up the netbook with the suse external hard drive connected it will ask to boot into OpenSUSE, the Fail Safe, or to install OpenSuse. When I select to install it it gives me the Error 18 Unknown File system.
I've tried formatting the internal hard drive twice. One as NTFS and again as EXT4. Neither seems to effect it other than when it's ext4 I can open it and it contains a Lost and Found folder.
When I interrupt the boot sequence by pressing c and going to the terminal and I use the root (hd +TAB command it tells me I have a hd0 and a hd1. The hd1 only has 1 partition which is ext4, which I'm assuming hd1 is the internal hard drive (I'm not sure how to check) and the hd0 is the external hard drive, which has three partitions. One with an unknown file system and two with ext4. When I try to enter the set up from the terminal it gives me the same error for any thing I put it (e.g. root (hd0,0) gives the same error as root (hd0,1), or root (hd0,2) and root (hd1,0)
Something like it cannot locate these two files I'm assuming it needs to boot. If anyone finds this relevant I'll retry it and post the files its missing.
I've been searching for awhile and can't find any threads that can solve my problem. From other threads, however, I have noticed that I should probably include my menu.lst, listed below
Code:
I have also ran the boot info script and received the RESULTS.txt file it generates. Listed below

Having problems with external hard drives. I may be wrong, but I suspect they originated with an upgrade to 10.04 last Christmas. Around that time I also started using Amazon's S3 storage system, and, as a consequence, I stopped using my WD 80G external drive, previously used to backup my important files.
A week or so ago I decided to start using the WD drive again. I can't remember exactly what I did, but it wasn't happy - never caused any problems before. When I plug it in, the on-off light as the front keeps flashing on and off, and when I try to remove the drive I get the message: Error unmounting volumne An error occured while performing an operation on "My Book" (Partition 1 of WD 800BB External): The device is busy
Details: Cannot unmount because file system on device is busy Assuming the device had died - it's about 5 years old - I bought a 160G Samsung S-Series drive - my but they do look neat! Unfortunately, this doesn't seem to have solved my problem. I plugged the new drive in, and it happily appeared on my desktop. It seemed a good idea at the time, but I then started to format the drive - using the default option of FAT. All went well at first, but then the format process stopped.
My new Samsung drive now seems to be operating pretty much as the WD device, I can't copy to the drive, and attempts to unmount it generate a response similar to what's happening with the WD drive. Currently, although plugged in, I can't see the drive on my desktop, although it appears under Places. However, when I try to mount the drive, I get the message: Unable to mount SAMSUNG A job is pending on /dev/sdb1

I plugged in my external dvd-r (asus) via usb. It showed me some message on shell, that it has detected the cdrom(although its dvd rom as well but nevermind) and its of ASUS. But how do i know which dev it was associated with in /dev/? Since i had to test something, i plugged it out, and save the output of ls /dev/ > ~/result.txt
after plugging the dvd-rom, i compared the results and was able to find that it was associated with simple cdrom i.e. /dev/cdrom. I wanted to know that is there any command that will tell me which /dev/ file was associated with external dvdrom? i tried to see in the following result
1) df -h ( no results, just the already mounted partitions)
2) fdisk -l ( same as above)
3) dmesg | tail (shown almost the same result as was shown on shell at the time of plugging the dvd)

I bought a new SD card which I intend to put some MP3s on - except that I can't write to it because it tells me the destination is Read Only. No-probs thinks I: I'll just reformat it.
"Error creating file system: helper exited with exit code 1: cannot open /dev/mmcblk0p1: Read-only file system"
Various chmod commands all result in Read-only file system. I tried umount then mount commands, but it couldn't find it to mount once I'd unmounted it using the same /media/ file path (I assume it's the only one).

My Redhat Enterprise Linux 4 with 6x partitions (/, /boot,/home, /usr, /var, /tmp) of 6.0 GB IDE Hardisk was working quite fine. I decided to create LVM on /home and /var partitions but due to some errors occured and I delete the /home partitions. That's why partition table altered. I then delete 4,5,and 6th partitions (/home, /var, /tmp) partitions and now try to create one by one but following error is coming:-

The Super block could not be read or do not describe a clear ext2 file system. E2fsck b 8193 <device> I have tried following commands,but could not successful:- e2fsck -p /dev/hda7 (where hda7 was created but afterthat it was deleted) e2fsck -a /dev/hda7

Have just assembled a new computer and thought I would install the 64 bit version of openSUSE 11.2 in a "Windows free zone". After a hiccup or two I have managed to get a system of sorts running but on trying to copy files from my old computer(via a memory stick) it tells me that Vfat is an unknown file system.On my old computer I am running 32 bit openSUSE 11.2 as a dual boot system with Windows XP and have no problems moving files between the two different file systems.Is it possible to get a 64 bit file system to read 32 bit file system drives and if so how do I do it?

I have been using lucky backup to backup my files. However, I am unable to get a list of all packages that are currently installed, turn it into a file, and then back that file up as well with this gui.Lucky-backup's execute function does not work.I would like to have my system backup all appropriate directories upon connection of an external usb drive.I would also like to run a variation of the following command:sudo dpkg --get-selections > /path to external drive/Linux Backup/app-list.log(I need to overwrite the file on every connect- not add to it! What needs to change to this?)1. What commands would I need to use to backup certain directories?2. How can I turn the above mentioned command to OVERWRITE the current file on the drive, and not simply add to it?3. Most importantly, how do I run these commands both immediately upon mounting of the drive, AND/OR "on command" without having to type it all out every time?

I'm a little bit confused with partitioning the filesystem in Linux. the difference between creating the file system with fdisk and mkfs (when formatting the disk). I can't clearly tell my problem, so please look at this picture:

I have configured a command line (9.10) server to forward all the system email notices to an external Gmail account.
All is forwarding fine except, all the emails from root have a return email address of "root <myaccountname@gmail.com>".
I do not think that it is a big security issue but, I would prefer that the root emails were forwarded to an existing user account on the server and then forwarded to my external Gmail account. That way the return address would not say "root" within the address but rather "existinguser <myaccountname@gmail.com".
Anyone have a thought on this? Is exposing the "root" name within the return email address a serious security issue?

Just installed Ubuntu 10.04 LTS netbook edition and everything goes well except for one thing.
When I connect my lcd monitor to the vga port the system lags. If I listen to music and browse web pages at the same time, the sound skip and when the page stop loading, music is ok. Also, the mouse skip. If I do circle with it on the desktop without doing anything else, it will skip.
The strange thing if I remove the external monitor and reboot the system everything comes back to normal.
I had Intrepid Ibex for 2 years without any problems. I remember a post saying that powernowd should be disable, but can't find the process from the startup list anymore.

I am running fedora 10 on my laptop. I use a usb Western digital "MyBook" 500Gb (ext3). I am using this hard drive since more than 1 year now. Lately I run into a single problem when I read a precise file. The laptop becomes totally unresponsive and I have to manually shutdown the computer. After start-up I can find that the /var/log/message file of my previous session has grown very quickly with "[sdb] Sense Key : No Sense [current]" and "[sdb] Add. Sense: No additional sense information" messages.
I found various similar question on the web, most of the answer were hardware dependent and kernel related. I tried various kernel hoping that my specific problem would be fixed in the next one but with no success (all the kernel since fedora 10 release and two testing one: 2.6.29.5-84.fc10 and 2.6.29.6-93.fc10), I don't have access to a Fedora 11 machine.
I replaced the usb cable and check that the power supply was working correctly.
I am joining part of /var/log/message and the results of lsusb (related to the external hard drive).

My father installed Kubuntu to his external hard drive to try it out, however, it is running extremely slowly. It takes a good minute and a half to boot to the Plasma desktop and it even seems to run faster off of the LiveCD.His system easily meets the specifications to run Kubuntu (4 gigs of RAM, decent NVIDIA graphics card) yet it slows to a crawl immediately upon booting. Does anyone know how to fix this? The hard drive is a Western Digital MyBook, 475GB model.
