General :: Command To Configure A External Hard Drive In Ext2 As A Secondary Storage Device
Mar 18, 2011
I have a Linux application(ProMAX 5000) running in a virtual Machine on my windows OS. I am using an external Hard drive of 250G in ext2 file system as my device for large data read, write & execute file system. I have already mounted the device from /etc/fstab. But i want my application to access this device as a Primary data storage device OR Secondary storage device. What command will i invoke to partition this 250G drive as my primary or secondary storage device.
Having just moved to Linux from Windows, I have never considered whether or not to partition my 250 GB external hard drive. As of right now it will only be used for data storage. Should it be partitioned? If so, what size partitions?
Hybrid Storage harddisks use a large non-volatile cache to save power and improve speed. I wanted to ask if there's a reasonably simple way to simulate that under Linux. Ideally there would be a FUSE-filesystem that does this, For now this is purely theoretical, but my setup would be a small home server (Sheeva Plug) with an external USB harddisk that goes to sleep after a few minutes of inactivity. To keep it powered down as long as possible, I would like to use a 16GB SD card as a cache for the harddisk, thus simulating Hybrid Storage.
The only possible solutions I found thus far were Hierarchical storage management packages for enterprise use, which are way too expensive for this task.
I normally use the "locate" command to find files that I have on my local drive. However, if I wanted to do this for an external drive, how would I go about this?
From what little I know about Linux, I'm guessing that it creates a reference file from which it performs the search when the command is typed. If I'm right this is updated at a given interval or when "updatedb" is used?
As the external hard drive is not always mounted is it best to create another of these reference files and have a different command (e.g. locateext) or something? Or is it best to add the external hard drive's location to the list of files that get added with updatedb.
The external hard drive which contains all my photos and where I backed-up all my important documents is no longer recognized. It is a three month old 500GB Iomage Prestige Desktop Hard Drive.When I plug it in, it is recognised as a USB device, because it shows up when I type lsusb, but dmesg gives this error message.
[19712.013250] usb 2-2: new high speed USB device using ehci_hcd and address 21 [19712.145347] usb 2-2: configuration #1 chosen from 1 choice [19712.147214] scsi25 : SCSI emulation for USB Mass Storage devices
[code]....
I popped the disk out of the casing put it on a SATA connect internally and then tried the file recovery programs testdisk/photorec and SpinRite, but both failed because they couldn't recognize the external hard disk.
I am setting up a Linux laptop for my parents, and want to also create some backup scripts to allow them to easily back up to an external hard drive. [And for them to be able to use it, it has to be super simple.]
For security purposes (should the external drive ever get lost or stolen), I want to encrypt the entire device using TrueCrypt. That means my scripts will have to use TrueCrypt to mount the backup volume using the device name. [Right?]
Now to the actual question(s): 1) Is there a way to ensure that an external hard drive will ALWAYS be assigned the same device name when plugged in? [That would be the simplest solution for me.]
2) Alternatively, is there a way (using bash scripting) to "find" the device name of a particular external hard drive, even if it might not be known in advance.
start getting Linux up and running. Like a lot of people, I chose an older computer I could fuss with, a 500mhz 256meg ram machine, and decided to install Puppy on a spare 40meg hard drive I have, as my bios does not boot from usb...I think...
Anyway, I have found that my bios does not recognize the hard drive when formatted to ext2! I have taken the drive and formatted it back to ntfs, and my bios recognizes it, and then back again to ext2, and nope, it's not there, thus I am still booting puppy from the cd...sigh...
Is my bios so out of date that I'm just out of luck? Is there anyway to check this?
I am working on a computer that the hard drive crashed. Inititially they had a virus, reloaded windows, and had the computer up and running. When downloading software it crashed and will not boot. I have tried all the numerous routine fixes with no success including using the repair discs. The repair discs no longer work and they are unable to get a second set. As a last resort I am able to access the hard drive when booting from Knoppix from a CD. There are a couple things I would like to try from Knoppix, but do not know if it is possible. First, Is it possible to load the boot files from knoppix? Second, can you roll back the drivers from knoppix?
My Red Hat EL 5.5 64 bit edition, I've install it on my primary hard drive 12 GB it works fine and then I added secondary 20 GB hard drive (sdb1) into this system and then format it as VolGroup01 see the attachment, but how come it doesn't show up ?
I have windows xp on my first hard drive and Linux on the second hard drive.The windows hard drive is labeled hda1 and the linux hard drive is labeled hdb1.I am using GRUB to boot the linux hard drive and it is installed on hdb.Is there any way to boot the secondary linux hard drive using the windows bootloader?I have tried several online tutorials for it but none of them work.
I got a dell inspiron 1501 laptop with a 80Gb sata drive what is the best solution to add data storage space for someone that love to have multiples operating systems at hand Note: I use mostly linux so I won't need to change my laptop for many years maybe ...
Are there any tools in Ubuntu that could defragment my MP4 player (Sansa E280R)? One of the songs on my MP4 player isn't showing its Album Name or Artist Name. I know I have the artist and album name tagged onto the MP3 because I set them both & double checked using mp3tag.
I just upgraded to 15 and was wondering if it was possible to specify which devices to prioritize a route through. I have my machine, a laptop, connected to my family's router for an internet connection and a wired connection to a personal router for a faster and private connection between my other two computers and a network storage device. Whenever the laptop is connected to my personal router everything goes through it and it can't connect to any external web sites. But when I unplug it and go only on my family's wireless everything is fine, except I can't connect to the storage device since it has no external connections.
so i used to have my harddrive mounted in fstab, to /mnt/diskS. than i decided to change the permissions to 766 global i believe i read somewhere with chmod. anyways so after that i checked to see if it worked and to my dis believe all my files are gone. or just arnt showing, the space taken up hasnt decreased but i just cant see any of my files. so i decided to take the harddrive out of fstab and restart my computer. and after restart when i click on the folder the harddrive is mounted in it says permissions belong to 1000?
I am running Ubuntu Server and I recently added a new hard drive to the mix. Not replacing the old one, but adding a second one.What I want to know is how to I access that hard drive? I know in the desktop version it auto adds it, but not in the server version I checked my media folder.I installed it to be my new Samba share hard drive. So how to I get at it to use it?
So my aim is to install openSUSEx64 11.3 onto my Macbook; but for whatever reason, upon boot-up, the system won't recognize the USB thumb drive with the expanded image of openSUSE on it. I followed steps in Terminal to expand the image onto the said USB stick and know it worked properly because Terminal said "Process Completed." Do I need a special type of USB thumb drive or am I missing something? I am using a late-2009 Macbook. By the way, these were the steps used to prep the USB thumb stick:
1. Open a Terminal (under Utilities) 2. Run diskutil list to get the current list of devices 3. Insert your flash media 4. Run diskutil list again and determine the device node assigned to your flash media (e.g. /dev/disk2) 5. Run diskutil unmountDisk /dev/diskN 6. Execute sudo dd if=/path/to/downloaded.img of=/dev/diskN bs=1m 7. Run diskutil eject /dev/diskN and remove your flash media when the command completes
I have this unique situation, I think. My TV plays certain files only through external USB storage. My Ubuntu server stores all of these files on local hard disks. I do not want to buy an external hard disk and then keep moving it between both. Now, strange as it may sound, is it possible to somehow connect my server to the PC and expose a given local hard disk connected to the server, as an external USB drive to the TV?
I have two hard drives in my computer, one for the operating system and the other solely for storage. They both have ext4 filesystems. Is there any way that i can have my storage hard drive to automatically mount on start up?
I've read the official documentation regarding hard drives and partitions. My pc has two hard drives. a 160gb primary hard drive with windows 7 a 1.5 tb secondary hard drive with about 80gb of free space I would like to know whether I can install ubuntu on the secondary hard drive, without touching any of the data present on that drive. From my limited understanding of storage, files are written all over hard drives during copy, move etc... Is the ubuntu partition manager smart enough not to overwrite any files during installation? Will I get a warning if there is a risk of any data loss on the secondary hard drive? I cannot backup any of the data on the secondary hard drive due to all my external drives currently being full.
if I try to install a linux distro on an external hard drive, while I have windows XP on my primary, will the Linux stlil install a Grub on the Windows MBR. Or have I got that wrong.
I have Red Hat Enterprise Linux 6 installed on my machine. I am unable to mount an External Hard (NTFS). I have tried several options which are as under:
Option 1:After making a dir /media/windows mount /dev/sda1 /media/windows/ -t ntfs -o nls=utf8,umask=0222 Option 2: mount -t ntfs /dev/sdb1 /media/windows
I've been thinking about it and I have a few ideas how I could do this...
I could always just image the drive...
Code: dd if=/dev/sda of=/media/EXHD/bakup_$(date +%F).iso Also; I could use rsync... Code: rsync -auv --delete / /media/EXHD/bakup_$(date +%F)/
[Code]....
I've been doing mostly "dd" images...but was wondering if I'm just wasting time backing up a mostly empty HD (256GB and only 5% is used...so dd-ing seems like kinda of a waste).
but I have literally just starting using Linux (Centos) in the last week or so. I am using a standalone PC that is not networked, and as I will be downloading and generating a lot of data on this machine, I would like to regularly backup onto an external hard driveIdeally I would likethis to happen automatically as there will be other people using the machine.There seem to be many different ways of doing this, and I am getting a bit confused about the best method to use.
I have a Seagate external hard drive and I want to use it to back up my home server since it runs Ubuntu 6.10 and the upgrade to 10.10. My problem is that I am not able to format the drive to use it. I can not change the permissons or if I try to format I have all sorts of trouble. I have tried doing it on the home server running 6.10 and another pc running 10.10 and had no luck. Is there a better way? I have even tried chmod and chown with no luck.
I am trying to recover files off a 3.5" IDE Hard Drive that had Windows ME installed on it. I have access to a MacBook, Windows XP Desktop PC, and a cd with Ubuntu 8.10 on it.
Attempts:
1) If I make the HD the only primary master HD it won't boot up.
2) If I make it a slave drive it won't boot up.
3) I purchased an external enclosure from Radio Shack which turned out to be crap and online reports supported this conclusion. I got nowhere with that thing. Bestbuy doesn't sell 3.5" IDE enclosures.
4) By using an IDE / SATA to USB kit, I am able to connect the HD to the PC via USB cable. XP will detect the drive, however the HD will not my displayed under "My Computer" nor "Disk Management".
Onto linux (this is where I grabbed the Ubuntu cd):
5) When connected, the HD will show up under "Computer" as a "USB Drive". When I double click on it I get the error "Unable to mount location Can't mount file".
I was in the process of backing up data from my hard drive to an external usb drive when the drive suddenly became read only. Does anyone know how I can make it read/write again? I am using Debian Lenny and the drive is ntfs formatted. I have another ntfs formatted usb drive that is not effected in this way.
I have a 250 GB external hard drive formatted with Windows NTFS file type.How do I format it to use linux and what file type is best. I'm done with Windows so that is not a concern.
Ubuntu 9.10 recognizes my Freecom 120gig external hard-drive (when it's plugged in) and I can manage its contents OK - except via the command line. I don't seem to be able to find its path-name. See below:
mike@mike-desktop:~$ cd /media mike@mike-desktop:/media$ ls cdrom cdrom0 FREECOM HDD mike@mike-desktop:/media$ sudo fdisk -l
[Code].....
Despite all this info, I fail to get into the external hard-drive from the command line.
