Running Arch from a usb drive[SOLVED]

I am trying to install arch on a usb drive with ext3 format. I have entered root=/dev/disk/by-uuid/... on the kernel line and in /etc/fstab file (as mentioned in the wiki). On booting I am dropped to a limited shell with few linux commands. On running 'blkid' there, I find that the fixed computer hard disk is detected as sda1,2 etc and usb drive is not being detected at all. The results are similar if I use root=/dev/disk/by-label/..
How can I boot from the usb drive.

Reasonable to run Arch from a CF drive?

I'm building a NAS box for my basement and the frame is going to be a Dell Dimension 2400. I'm using 2x 2TB sata drives which will be configured in Raid-1 for redundancy purposes(losing a drive and everything on it sucks).
Anyhow, I want my two storage drives to be completely dedicated to my data so, I've decided to investigate the possibility of installing and running Arch on a CF card connected via IDE. I've seen mixed yays and nays online from my research, but, in the end, the Arch community has always had not only the best documentation but also one of the most knowledgeable communities I've seen.
So, What do you think?
Oh, and I plan on running X with openbox for speed. I'm just running a couple web daemons to download my shows.
Thanks!

EDIT* - eheheh, I just found an interesting article about installing sickbeard and sabnzbd on freenas.
Awebb wrote: Does it have to be Linux? If you're not too shy to use BSD, I recommend trying FreeNAS. It has everything a home server needs and it is even capable of satisfying a mid-size corporate's file server's requirements. You wouldn't need openbox, it comes with a very sophisticated web interface.
Its going to need to be able to run
1) Sickbeard
2) Sabnzbd
I did briefly examine freeNAS on their website. seems nice and although I know nothing about freeBSD, after moving through various linux distros and then finally successfully installing and using Arch, I'm sure I could figure it out. Actually, originally I planned this project in a way that would make this machine a standalone NAS box using freeNAS. It wasn't until a couple weeks ago I decided that if I did that, it would mean that I would still need some machine to stay on 24/7 which would run Sickbeard and Sabnzbd to supply video content to the NAS box. This defeats a portion of my purpose in that I currently have everything running and stored on what is more of a gaming machine with a large PSU and I'd like to save the power and not have that machine run all the time.
So, the idea was born to just build a box in which its primary function is to store media however it does have an OS for the purpose of running these two web servers so that it can be a lone machine.

Dual boot arch from second hard drive [SOLVED]

I have two sata hard drives connected. Hard drive 0 has my working updated version of arch.
I'm trying to boot off the second hard drive that has an older installation of arch. I have added this to my menu.lst of my first hard drive:
# (2) Arch Linux 2.6.31
title Arch Linux 2.6.31
root (hd1,0)
kernel /vmlinuz26 root=/dev/disk/by-uuid/29523114-ab52-4a9b-b93f-e2da915c0dc1 ro vga=773
initrd /kernel26.img
I have also tried using /dev/sdb1 on the kernel line with the same results. The uuid is correct I am able to obtain that from /dev/disk/by-uuid/
this is definately where the vmlinuz26 file resides for that hard drive. I can mount it and see it.
But when I choose this option, it tries to boot but then I get:
kinit: init not found!
Kernel panic - not syncing: Attempted to kill init!
Pid: 1, comm: init not tainted 2.6.31-ARCH #1
What do I need to change? Do I need to add something to that initrd line? Thanks.

I had to change the uuid to that of the root partition on sdb (the second hard drive) even though I had a /boot partition on it (sdb1). It is now working.
# (2) Arch Linux 2.6.31

Running a boxee media server from a usb drive

I'm replacing my current boxee server with a little ion nettop. It will have an atom 330, ion graphics and 2gb ram. Instead of putting a hard drive in it, I want to use a usb drive with a persistent linux install to run the OS. For the sake of minimizing noise, heat, power consumption... I'm thinking of using one of the lightweight ubuntu variants or ubuntu minimal, mainly because boxee works best in ubuntu. I'm also toying with using arch since boxee-source is available in AUR.
Will running it from a usb drive cause me any issues?
All the media will be stored on an external hard drive or streamed over my network/internet. Theoretically, it shouldn't be doing a done of reading/writing to the flash drive correct? Shouldn't everything be loaded into ram?
Thanks. Just trying to get a some opinions of people smarter than me before I go through with this.

Network boot?
I only throw this out there because when my father finally upgrades his TV I'll pitch in a lightweight build so he can stream media from my system instead of asking me "hey can I get some new movies on my usb drive" to watch on his laptop. I had been toying around with the idea of doing a network boot so I can more easily manage the upgrades/system from my end... rather than taking the twenty steps to the living room with a keyboard. Additionally, the very same reasons you put forward were also considerations of mine. I also considered a USB boot drive, but concern about the longevity of such a solution led me to consider the PXE solution.
(plus since I know next to nothing about setting up such a system it would be an excellent opportunity to learn)

Does anybody knows how to install Windows 7 from a USB drive on 2010 MacBook Air running Lion?

Does anybody knows how to install Windows 7 from a USB drive on 2010 MacBook Air running Lion?

Tell my wife that!
This is the best I can do. This way you can use the 2011 MBA way to do things.
Look for the post from @jacktourist. (on page 2 about half way down) This seems to be the easiest.
There are a couple of more similar to this with pictures I've seen around but can't remember where.
Here's another search with added info. It's easier then it sounds.

How to install Windows 7 from a USB drive!

This is even easier than installing Windows XP from a USB drive, and will also reduce the time taken to install Windows 7, it took me about 15 minutes!
The advice in the guide is also applicable to installing Vista.
You need basically:
a USB flash drive at least 4GB in size
a Windows 7 DVD
To sum up:
Format your USB drive, with the NTFS filesystem
Open Command Prompt as an administrator, and run the Bootsect.exe program off the Windows 7 CD to make the USB drive bootable
Copy the contents of the Windows 7 DVD to the USB drive
Restart your PC, press F11 (or whichever key it is) to access the Boot menu, and select your USB drive to boot from

Quote from: bnborg on 16-February-11, 10:28:04
I have done this and it is simple.
I cleaned and (re)formated an 8GB flash drive under Windows7 using diskpart. I chose quick format and a fat filesystem. It doesn't need to be ntfs. I had diskpart mark the partition active. I copied the DVD contents to the flash drive. I also made a folder on it for motherboard drivers.
After that, I booted the drive on a new machine. Windows7 setup came up, and didn't find any hard drives, other than the USB flash drive. I clicked the button to load drivers, and pointed it to the folder I had copied them to on the flash. Windows installed without problems.
Hi bnborg..Do u mind sharing with me your motherboard driver folder? I have the MSI U135DX Netbook and each time I hit the button to install Windows 7 it asks me for some mobo driver...Think i might need it to get tru with a successful install..

Running audio from an external drive question

HI there,
i am waiting the delivery of a high quality firewiredrive to run my audio tracks for my g5 imac.
I am a beginner at logic and i have logic express7.0 with logic pro 8 on its way.
In fact am a beginner at computer music. For the last 5 years i have been recording on an akai dps16 so this is a big learning curve right now, thought i have already made my 1st c.d. on logic express. Logic is awesome.
so
i am trying to get my head around running audio from an external drive as everyone recommends and instead of waiting for the new firewire drive to arrive i thought i'll learn this using my 500gig maxtor usb2.0 drive.
i have sussed out the record path business and all seems well. I have created 24 tracks of audio and i can see them in the audio folder in my logic project in my maxtor drive. So (i think) i have learned how to run audio from the maxtor, but what seems a bit odd to me is that when i run the exact same song from the internal drive ( I copied it from the maxtor drive) there doesnt seem to be any increase in the load of the system memory or the cpu as seen on activity monitor or logics audio performance meter.
I would have expected the identical song running from the internal drive to be more taxing on the computer.
Maybe i am doing something wrong but i dont think so.
Any help would be greatfully appreciated
Tom

The problem with internal drive is that is accessed by the OS and by Logic.
With a powerful Mac 24 tracks recorded at 16 bits and a sampling rate of 44100Khz are not n issue but increasing these values or the number of tracks the problem will appear and you will see the disk I/O meter going up very fast.
At that point you will begin to experiment audio hiccups before and a song stop later.
The same problem appears with drivers that have a reduced band (like USB 2.0) while firewire ones are faster, more stable and don't load the CPU.
cheers

Backing up from one USB Drive to Another

I have two WD USB drinves that I use for my photos, one as the primsary drive,the other as the backup. When these were connected to my Windows PC I could use Western Digital's WD Anywhere Backup software to provide an "instantaneous" back up of any of the photo files that I hadd added / changed on my primary drive. This worked like a charm. Using the software with my USB drives connected to me MacBook Pro . Mavericks laptop the software thinks that it is working perfectly but is not backing up all the files. On a test I specified a folder with 40+K files and 240GB of data as the folder to be watched and backed up. The software reported a successful backup but only 11K files and 60GB of data had been transferred. I reported this to WD who indicated that the software is designed to back up from the coputer's hard drive to a back up frive, not from one external drive to another.
My question is: Does anyone know of any software that will run as a daemon and automatically back up new / changed files from one USB drive to another? Obviously I could do this with any of a multitude of products if I scheduled hourly/daily backups. However, I would prefer the convenience of "instantaneous" backups as soon as a change is made within a watched follder. From what I have read Chronosync seems to be the best backup software for Macs but, as one reviewer noted (http://www.macworld.com/article/2011101/review-chronosync-4-3-5-a-multitalented- file-sync-and-backup-tool.html) "I would like to see ChronoSync go one step further and offer an option found in some other sync software: the ability to watch specified folders and synchronize changes as soon as they occur rather than waiting until the next scheduled run." Can anyone point me to the "other sync software" that offers this capability?
Thanks in advance
Brian Catterall

SOLVED
Once I got Time Machine to perform totally new backups it picked up the new external drive containing my images.

How do you autorun a Flash Projector (Windows) from a USB drive?

I got a Windows Flash Projector (.exe) that I need to autorun from a USB drive. I just want the user to be able to plug in the USB drive to their machine and have it start running without any menus. I've been using the following with no luck:
[autorun]
open=KSF_USB_main.exe
The project is composed of a number of .swf files that load into the "KSF_USB_main.swf" file. There are also PDF and FLV links within some of the movies.
I have the "autorun.inf" file and all other files (including the .exe Projector file) on the USB drive. When I plug it in to a PC it brings up the "What Do You Want To Do?" window and doesn't autorun.
I've tried some 3rd party software that creates a menu file with no luck.
Any suggestions?

This feature may have been disabled in some versions of Windows and some types of USB drives:

Want to run iTunes from an external drive, how?

I want to run iTunes from my external drive, I have already made back ups of my library and media files but I can't figure out how to save iTunes to the external drive? When you download itunes it just automatically downloads to the computer. Can you even do this? If not, how can I use the saved info on my external drive (library and media files) with my itunes on the computer. The problem we are trying to solve is a lack of space on our computer and we want to free as much space as possible. Thanks!

Drag the iTunes library to the external drive, launch iTunes with the Shift key held down, and point it there.

Booting from external USB drive

I was wondering if there is any way to boot from a USB drive that I have? I partitioned the drive, erased it, and its basically ready to go. But I can't install Mac OS X on it because it says that I cannot reboot from the drive.
I know that iBook G4s generally can't boot from a USB devise but is there any way to get around this?

If you're computer is having kernel panics there's a conflict; either software or hardware. 2GB of free space isn't enough but I haven't seen anything that suggests KPs are caused by too little free space. Your computer should start fine with 2GB free. It may have problems after a period of use but it would startup and run.
Try starting in Safe Mode. If successful move some of your files to the external drive and then restart normally. If it KPs again, restart in safe mode and disable all startup items in System Preferences>Accounts>youraccount and restart. If it KPs again go through the linked troubleshooting steps by Dr. Smoke step by step. That's the only way to resole your problem.

Can I import catalog photos from a usb drive?

I have imported photos from a catalog into a new catalog. Some of the photos in the catalog are located on a remote drive. The drive is not listed when I select the photos to be imported. Is it possible to import catalog photos from a usb drive?
Howie

Hi Keith,
"Import from another catalog" is a selection found in the Lightroom "File" drop down listing. Sorry I wasn't clear in my reguest. I have used this function to import photos in to my new Catalog from my old Catalog. During the import process, Lightroom creates a working catalog from which photos can be selected. A file list on the left side of the window displays the available hard drive folders. Once the photos to be extracted are selected the source folder is checked. The import button, on the bottom right of the window, is highlited to execute the import function. Since the external USB hard drive is not listed, the import function is not available.
My question: how do I enable the import from my USB drive? Perhaps I will have to move the files back onto my internal hard drive using my Lightroom's old catalog.

Hi, my mac air is really low on disk space, can I remove itunes (which is huge) to an external hard drive to free up space?...and then run it from the hard drive instead of the mac,even if the mac no longer has space to accomodate the size of the library?

Yes.
Copy your music iTunes Library folder to the external drive and change the Advanced settings in iTunes to point to this new location.
Once you're happy with these changes you can delete the same Library from your User account to free up space on the internal drive.

Running iTunes from external hard drive, new computer, where to start?

I've seen several threads relating to this, but I'm a bit confused. For some time we have been running iTunes from an external hard drive with no issues. We now have a new laptop with windows 8, and I'm not sure where to start to set up iTunes (we replaced the computer with a laptop). Do I need to do a new install of iTunes on the laptop? Do I install it to the hard drive (C) or to the external drive (G)? My biggest source of concern is losing the library. I also want to be sure that we can continue to run iTunes from the external drive, I don't want it taking up space on the laptop hard drive.

With more & more people looking towards external drives as a storage solution, it's important to warn them, that although using one within iTunes is a great idea, it comes with its issues & can be a step towards a disastrous sequence. In such a scenario, each time iTunes is launched it'll look for the library that resides on the external drive, & if that drive's not connected, iTunes will open with an empty library. You know what's comming next, rite ? An empty iDevice. This happens because 'by default' iTunes is set to Auto-Sync & if you're using an external drive, the potential for a messy problem goes way up. So in short, remember these points. when using an external drive(library).
. Always connect your external drive prior to lauching iTunes.
. Always ensure iTunes sees your external library prior to connecting your iDevice.
. Disable the 'Auto-Sync' feature from within iTunes prior to connecting your iDevice.
. Always wait to connect your iDevice until thee aforementioned points are confirmed.
As stated earlier, using an external drive with iTunes isn't a problem in & by itself. But if the external drive's disconnected & the 'Auto-Sync' feature's left at its default setting(enabled), a family member could loose all their data simply by connecting their iDevice to the PC/Mac. Or be in for a time consuming lesson.
PS: At the very least one should research the topic themselves. http://ipod.about.com/od/advanceditunesuse/a/Itunes-External-Hard-Drive.htm
