General :: Installon An External Hard Drive On A Macbook?

Jul 27, 2011

From some Googling, I've found that you can use Bootcamp to install Linux Macbook.However, I have a Macbook air and do not have sufficient disk space. I was wondering if I could install it on an external drive, and boot it from the Macbook? I think that the problem is the bootloader. But, if I still use Bootcamp to install Ubuntu, it would set up the bootloader, and then I would just install to an external?

General :: External Hard Drive Won't Mount On Karmic - Macbook 2,1

Jan 30, 2010

Manually mount or fix my external hard drive. I can't format the drive because I have important data on it. The drive is 1TB Select USB 2.0 Desktop Hard Drive from Iomega. When I plug it in, a message appears that reads:

"Error mounting: mount exited with exit code 32: mount: wrong fs type, bad option, bad superblock on /dev/sdb2,missing codepage or helper program, or other error. In some cases useful info is found in syslog - try dmesg | tail or so".

Also, I plugged in the drive, typed the command "sudo fdisk -l" in the terminal, and received the following:

WARNING: GPT (GUID Partition Table) detected on '/dev/sda'! The util fdisk doesn't support GPT. Use GNU Parted.

WARNING: GPT (GUID Partition Table) detected on '/dev/sdb'! The util fdisk doesn't support GPT. Use GNU Parted.

Partition table entries are not in disk order

General :: External Hard Drive Won't Mount On Karmic, Macbook 2,1 Again?

Sep 3, 2010

Earlier this year I encountered a problem with my external hard drive; it would not mount automatically and I kept getting an error message. Last time I was able to fix it by typing in the terminal 'sudo fsck /dev/sdb2'. Once again it's not mounting automatically and I'm not even getting the error message. I can't format the drive because I have important data on it. The drive is 1TB Select USB 2.0 Desktop Hard Drivefrom Iomega. Also, I plugged in the drive, typed the command "sudo fdisk -l" in the terminal, and received thefollowing:WARNING: GPT (GUID Partition Table) detected on '/dev/sda'! The util fdisk doesn't support GPT. Use GNU Parted.

Disk /dev/sda: 120.0 GB, 120034123776 bytes

General :: Backing Up To An External Hard Drive?

Apr 6, 2010

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).

General :: External Hard Drive Will Not Format?

Nov 4, 2010

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.

General :: External Hard Drive Won't Mount ?

Jan 20, 2010

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".

Allow me to show you some commands I ran:

General :: Install Slackware To An External Hard Drive

Oct 21, 2010

I recently had a laptop die on me. I, of course, then to recover the hard drive. I wanted to install slackware to a partition on my drive, so I can have a linux distro with me( also I have a FAT32 partition for shared space) I have a Slackware 13.1 disk one (which i need, since I don't need a graphical environment or anything), and proceedd to follow setup program. I have a 5GB '/' partition, a 10GB '/home' partition, and a 2GB swap partition. My ROOT partition is bootable. The setup program seemed to complete succesfully, but it won't boot. When I choose to boot from my hard drive (in the bios), it reverts to the slackware disk, if present, or the standard windows drive.

I installed LILO to the superblock of my external, because according to the setup the MBR option installs to "The MBR of your first hard drive", and I wasn't sure if that was right, since my first hard drive is my windows one. Since i'm not even seeing LILO, I think it has to do with installing to the superblock. I want to be able to boot a basic linux distro if needed from whatever computer I want. I'm not sure if slackware was the right choice, but it was one that I had worked with installing before, and knewthat you didn't necasarraly have to instal all the graphics stuff. I just want a shell. Sorry if my question sounds retarted, I'm new to the whole "Multiple drives, and operating systems" thing

General :: Doesn't Detect External USB Hard Drive

Aug 4, 2010

In Ubuntu 10.04 all I had to do was turn on my external hard drive and it would automatically be detected and mounted. I just switched over to Ultimate Edition, which I think is Ubuntu 10.04 with a lot of stuff added on to it. The funny thing is when I turn on the external hard drive it doesn't get mounted, and I don't think it's even being detected. I looked in gparted and it doesn't show up there. If I boot into Ubuntu 10.04 and turn on the hard drive it still gets detected and mounted, so there's nothing wrong with it. Ultimate Edition can detect other things connected to USB, like my iPod, so I'm wondering why it can't detect my hard drive.

Edit: When I do tail -f /var/log/messages and if the drive gets detected, this is what it says:

[ 230.520892] usb 1-2.4: new high speed USB device using ehci_hcd and address 6

General :: External Hard Drive Mounted As Read-only

Mar 16, 2011

I administer a remote server via SSH that runs CentOS 5.5. I have been unsuccessful in all my attempts to write to two different external USB hard drives with a single ext3 partition when logged in as root.

When attempting to create a "test" directory I get one of two messages:

Quote:

Both drives *appear* to have filesystem issues. When I run an fsck on either drive, I get:

Quote:

Keep in mind this is a newly-formatted, empty drive.

Not putting stock in the odds that I've had two hard drives (different sizes and brands) with the exact same hardware problem, I'm going to assume this is a software issue, although maybe it isn't. Hence, my post in "Linux - General". I've heard talk elsewhere of controller (chipset) issues coming into play. Is this valid?

Okay, here's the information you'll need to make a diagnosis....

Here's the output of a "df -h" command:

Quote:

Here's the contents of my /etc/fstab:


Quote:

Here's the output of "cat /etc/mtab":

Quote:

Here's the output of a mount command:

Quote:

Here's the output of fdisk on the device in question:

Quote:

The number of cylinders for this disk is set to 48641.

There is nothing wrong with that, but this is larger than 1024, and could in certain setups cause problems with:

1) software that runs at boot time (e.g., old versions of LILO)

2) booting and partitioning software from other OSs (e.g., DOS FDISK, OS/2 FDISK)

Command (m for help):

I've got someone with access to the box if necessary. But it might take days to implement solutions since this isn't his full-time job. Remote solutions are, therefore, preferable.

General :: Can't Start The Box Unless External Hard Drive Attached

Jul 21, 2010

I had installed Ubuntu 10.04 onto an external hard drive connected by USB to my laptop:

sdd partition
Windoze still resides on the box's internal hard drive:
sda2 partition

I also partitioned the internal hard drive so that I have a repository where my documents etc can be accessed by either linux or windoze:
sda3 partition (FAT32) I'm assuming that Grub is on the external drive somewhere - as is probably now the Windoze MBR. I'd like to be able to give my wife the ability to start the box (and boot into Windoze) when the external drive is not attached (so that she doesn't have to take the latter with her when she needs to be mobile with the computer). What do I need to do to move grub and the MBR back onto the laptop's internal drive? Or, I suppose: What do I need to do to obtain the functionality that I'm looking for? I'm getting somewhat more comfortable with the command line but, I still need a bit of hand-holding

General :: Copying Files From One External USB Hard Drive To Another?

I have two USB 2 external hard drives. I want to copy about 30 gigs of data from one to another. What command line command do I use ? I was thinking of using cp with the -R and -n options, but I have no idea what devices to refer to. I can't find any external hard drives in /etc/fstab and I'm not sure what /dev device each USB external hard drive uses. I just want to copy the files and the directories that they are in just as they are. There are no links and I do not want to do a backup.

Hardware :: Macbook - Transfer Hard Drive To New Desktop

May 30, 2011

I just installed Ubuntu a week ago on a computer that my grandma wiped windows off of by accident...unsure how.

I have a Macbook Pro laptop that is currently not working. Had some water poured on it by a drunk girl. (Oh the misfortunes of computers)

I would like to take the hard drive (and possibly other usable parts) of the macbook and add them to this desktop.

My question(s):

Can I add the old hard drive to my new computer without formatting and erasing the data, thus having access to all of my goodies?

OR

Is there a way to transfer the data over to my new computer BEFORE I format?

Red Hat :: Won't Start Macbook Nvidia SATA Hard Drive

Jan 22, 2011

I have REHL 6 Desktop. I have a macbook pro 7,1 with nvidia graphics and (I believe)a nvidia sata controller. I have fedora currently installed with no problems during or after installation ( with a few drivers of of course).

When I boot with the disk i burned ( works on other computers) it comes up of a list of devices to select and when i select local CDROM or DVD it goes to select drivers. So, then I tried "burning" the installation files to an external hard drive then I used the DVD to boot and selected Hard Disk then selected SDB1 (path of external HD). With this method I get to the Graphic installation screen and can go to the part were it says custom partitioning. I select ok then it say the only disk that is available is SDB1 (EXTERNAL).

General :: External Hard Drive - Poor Man's Hybrid Storage?

Mar 2, 2010

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.

General :: Installing Debian On External (connected Through USB) Hard Drive?

Apr 23, 2011

I've got Vista installed on my notebook and I've bought an external drive (1,5 TB, but its size shouldn't matter in this case) and after formatting it I left 10 gigs for future purpose. Now, I decided to install 64bit debian on the unallocated 10 gigs. And so I did. To be precise: I have SATA drive inside my lap and hard drive (it's also SATA inside the cover) connected to my lap through USB. Boot sequence was 1)CD/DVD 2)hard drive 3)removable drive. During the installation the installer detected my internal drive as /dev/sda and my external drive as /dev/sdb. I decided to install grub on /dev/sdb (it was logical to me, since I didn't want to mess up my regular drive's MBR). Installer created 5 partitions on my USB drive. After booting from my external drive (look below*) I've got a message saying

Code:

error: no such partition Entering rescue mode... and after that I was in grub rescue console. When I typed ls I've got an output

Code:

(hd0) (hd0,msdos1) (hd1) (hd1,msdos5) (hd1,msdos2) (hd1,msdos1)

When I tried to type

Code:

ls (hd0)/

I only got a message

Code:

error: unknown filesystem This occured for all the listed devices... On my internal drive there were (during the installation and running the live cd) 3 partitions detected (vista os, data, rescue disk) so I don't understand the output that ls in rescue console gave me. about booting from external drive: I did that after pressing ESC - I've got a prompt to choose which device I want to boot from - this wasn't working properly; after changing the boot sequence the grub started but with the abovementioned error message...

If there's any info about exact names/types/devices of my installed partitions needed I will run live CD and check it. If any other info is required I will provide it (I tried to describe the problem in the most precise way ) What I was thinking about: maybe there is a problem with ordering of the devices - when I boot from DVD my removable disk is treated as the "second one" and after booting from the removable disk it becames the "first one" or something like that? If any of you have any good info on how mapping of the device names works it would be appreciated, since I couldn't find anything useful or I just don't know what to ask google about.

1) How to install Debian on a removable disk (I had no problems with installing Linux on pendrive but I did that from VirtualBox and it was some time ago) OR how to install GRUB on a removable disk? (unfortunately, I cannot install 64bit system through VirtualBox)

2) What's the logic behind naming devices under /dev? How come the devices in grub have their names mapped as hdx etc and I've read that hdx are the names for IDE/ATA drives and sdx is the proper name for a SATA or USB device
