OS X :: Clearing Ubuntu Server USB Drive?
Dec 11, 2010
I have created a bootable USB flash drive to install ubuntu on my mac. Is it possible to restore that drive and clear it of everything, so that I can use it to store data again. It is quite a large capacity USB, so I would like to use it further. I have tried to drag the files into my trash, but it doesn't allow me too. If this is of any help, I used this tutorial on the ubuntu website to create the bootable drive via terminal: Ubuntu Server Guide ^ Click USB, Mac option.

I have a box running Ubuntu 12.04. I want to use a printer that is hooked up to this machine and also the DVD drive
I am using a Mac Mini with Lion Server (this is a Mac Mini with no DVD drive).
The Ubuntu machine sees the Lion Server and accesses files from it.
The Lion Server sees the Windows based machines on my network and accesses them fine The Lion Server does not see the Ubuntu machine.
Info:
Mac mini Server (Mid 2011), Mac OS X (10.7.4)

I have read that if you buy an AirPort Express, you can plug in a pair of speakers and create a wireless speaker environment. Just curious if I could save the $99 and do it with the Ubuntu server. Can I plug in a pair of speakers into the server and have the MacBook's sounds play through them?

I'm trying to install ubuntu from a thumb drive. Basically, I'm converting the .iso to an .img, and restore the thumb drive from the .img, trying to make it bootable. I'm following the procedure form the ubuntu website. Drag and Drop a file from Finder to Terminal to 'paste' the full path without typing and risking type errors.
Download the desired file
Open the Terminal (in /Applications/Utilities/ or query Terminal in Spotlight)
Convert the .iso file to .img using the convert option of hdiutil (e.g., hdiutil convert -format UDRW -o ~/path/to/target.img ~/path/to/ubuntu.iso)
Note: OS X tends to put the .dmg ending on the output file automatically.
Run diskutil list to get the current list of devices
Insert your flash media
Run diskutil list again and determine the device node assigned to your flash media (e.g. /dev/disk2)
Run diskutil unmountDisk /dev/diskN (replace N with the disk number from the last command; in the previous example, N would be 2)
Execute sudo dd if=/path/to/downloaded.img of=/dev/rdiskN bs=1m (replace /path/to/downloaded.img with the path where the image file is located; for example, ./ubuntu.img or ./ubuntu.dmg).
Using /dev/rdisk instead of /dev/disk may be faster.
If you see the error dd: Invalid number '1m', you are using GNU dd. Use the same command but replace bs=1m with bs=1M.
If you see the error dd: /dev/diskN: Resource busy, make sure the disk is not in use. Start the 'Disk Utility.app' and unmount (don't eject) the drive.
Run diskutil eject/dev/diskN and remove your flash media when the command completes
Restart your Mac and press alt while the Mac is restarting to choose the USB-Stick
Everything goes through fine, except, when I restart my mac to see the boot options. All I see is Macintosh HD

I have a cd copy of ubuntu that works fine but is really slow.
I installed to a usb drive multiple times and keep running into the same problem: The flash drive shows up as "Legacy OS" in rEFIT and boots into my windows partition when I select it. It doesnt show up when I hold alt/option on startup. It also doesnt show up in the startup disc menu in system preferences even though its on the desktop.
I have used different usb drives and, like I said, have installed it multiple times. Every site I have gone to uses the same installation method (using ubuntu from a cd) and I dont understand why it wont work.
I have posted this probably in other sections and no one ever responds so Im hoping this will change.

I tried to install Ubuntu 9.04 on 500 GB external drive and it will now no longer boot Ubuntu nor Mac. I need to know how to fix this. Things already tried:
*Backing up harddrive and installing Snow Leopard (10.5.4 is what it is)
*Deleting the external harddrive and reformatting it.
I want to be able to keep all my mac files. The file with a ? appears when the Ubuntu livecd is not in. (that is the only thing that boots).

I got this weird issue with my 4 GB flash/thumb drive. Basically, in OS X it seems to work perfectly fine. I formatted it to HFS+ and transferred files to it, ejected it, then put it back in, the file is still there, I transferred it back to the computer, and it opens fine. However, when I put it in any machine running Windows, it'll only recognize 48 MB or something. It refuses to format the whole 4 GB.
When I plug it into an Ubuntu machine, it would recognize a "4 GB filesystem", but would throw up errors anytime I try to interact with it. And when I tried to format it with Ubuntu, it would invariably fail. From Windows and Ubuntu's views, the flash drive is no good. But then why does it *seem* to work fine in OS X? Yes, I have formatted the drive with MS-DOS (FAT) in OS X, same results in Windows and Ubuntu.

I know this isn't "Windows" per say, but I couldn't really find a closer forum to post in. I installed Ubuntu following their online guide using Bootcamp and such because I was curious. Now, it's not really working as much as I would like it to, and I'd like to remove the 90 or so Gigabytes I gave to Ubuntu in my partition.
I tried using the Disk Utility, and it always gets stuck on "preparing to remove partition". I waited for an hour and a half once, and it still had not progressed. I also tried using the Disk Utility off of my Mac OS X installation disk and saw the same failures and results. What can I do to remove this plaguing Ubuntu partition off of my hard drive for good?

My system is MacPro 2009 with 10.6.8 server and Apple RAID card. Last week, RAID util just notified me of one drive is not viable, so i decided to replace the drive today. The configuration of my system is... There is an Apple Raid Card for HW Raid system Bay 1 = 640 TB drive with Mac OS X 10.6.8 server installed Bay 2, 3, 4 = 1.5 TB drives set up as RAID 5 below is what I did to replace the degraded Bay 4...
1. I shut down the system
2. replaced the corrupted drive with the new hard drive
3. tried start the machine again.Now my machine refuses to start up with the blinking question mark... I guess that the system fails to recognize the new drive or cannot find the system files...
4. So I put back the degraded drive...
5. The machine still won't start...
6. I tried to use the 10.6 server installation disk to boot up the machine to check if I can fix the system via disk util; but, everytime I do this, I got kernel panic...
7. resetting PR Ram didn't help, cannot boot up via safe mode as well (since the system file is not accessible now, I guess...).
8. booting via 10.6.2 server installation DVD still gives me kernel panic...
Why would my system corrupt by just replacing one degrade drive? The Mac OS X is not even the part of the Raid system... How am I supposed to fix this issue with out the installation disk?

I admin a network of Macs that use a 10.3.9 based OS X Server machine as a backup server. There is an iDisk account the server uses for iDisk backups and once a month I run a manual full back to CD. Tonight, the CD backup failed to run since the boot volume was basically full. Upon further inspection, I learned the boot volume is 6GB on a 20GB drive. So, I'm looking to possibly replace the hard drive. I'm also considering replacing the entire server with more modern hardware but that's another discussion.If I were to replace the 20GB hard drive in the server now with say a 60GB (we're talking PATA/IDE here) what would be the best way of doing it? We're talking about the boot volume now so I would need to move the OS and MBR and everything to the new drive.

I've deleted a lot of music/movies/apps/podcasts in the past, however have almost always accidentally clicked 'Keep files'. Is there any programme/script that will sift through my library and delete anything in the folder that isn't there?

I am new Mac users so I am trying to find alternative programs to the once I used under windows. Some are ok some I 'move to trash' and look for easier to use. When I don't need program anymore I 'move to trash' the program in my applications. Is that enough? I know mac is different, but under windows you needed to run several cleaning programs regularly to clean up all the bits and pieces left behind.

Safari 5.0.5. MacOS 10.6.8..I am developping complex HTML+JavaScript. I notice that after a while (~30 mn) Safari does not clear its cache and re-uses old JS scripts. I have caches disabled in the development menu. Clearing cache or reinitialize Safari from the Safari menu is of no help.Only way is to delete the cache.db file in Libray/cache/com.apple.safari, exit Safari, empty trash, then relaunch !

My MacBook Pro 17" 10.5 has been working flawlessly for almost two years. I am in an RV resort and their WiFi system has been updated. Prior to that everything worked fine with the old WEP password. However, with the new system and new WEP password my Mac Book Pro will not acknowledge the new password. I know the info I'm inputting is correct because my old iBook is working fine with the new password. I can only conclude that I need to clear every thing out in respect to the old name (The new name hasn't changed), IP address, and WEP password, so Airport will see the new info as if it is for the first time.

I'm not sure if this was asked before but I couldn't find it in a search. I use Safari 4.0.3. When I clear the browser history, the folder library/caches/metadata/safari/history still has a log of the pages I visit. Is there anyway to clear this besides manually. Would clearing this folder change anything on my mac?

I downloaded Mackeeper and it told me junk was slowing down my Mac but after it asked for $88 i quickly uninstalled it. Im worried it left a virus that slowed down my Macbook Pro. Even tho everyone says Macs don't need antivirus ware, is there something i can run to make sure there isn't anything harmful leftover? Also what is safe to use to clear out junk to improve how my Mac runs?

It says 12.6 GB of movies; I don't know where these movies are. I don't have any downloaded. How can I find them to delete them? I have also deleted all of my photos except three and it still says 11.44 GB. That docen't seem right either.
When I search my computer, files in Dropbox come up. But I thought those weren't included in my computer? (There are no movies on there, either.) I can't even download an update.

In the Finder sidebar under shared computers, we seem to be getting duplicates. Admin Mac (1), Admin Mac (2) (when it's the same computer). How do I clear out this list so that we don't have 13 Admin Mac's on our list?
I have gone through and turned off sharing preferences restarted computers and turned Sharing preferences back on. I now see the correct computer but can't get rid of the duplicates now.

Moved all my movies audio etc and stored on external HDD, but as I have lion and time machine it saved a local back up so that when time machine was synced it didn't miss anything.Seems sensible, so next step was to sync time machine, expecting that the local back up would disappear when it shifted to TM. It didn't...why in gods green earth is the local back up there even though TM connected the whole time and up to date? I've restarted, loaded all updates and verified disk. How do I get to the "it just works" part without having to Delete this double up (32GB "backups") via terminal etc....

I have a PowerMac G3 running OS X Server 10.4.7. There is an 80GB ATA boot hard drive and a SATA card and two 250GB SATA drives. One SATA drive is existing and has data on it; I just installed the second one because I want to mirror the 1st drive onto the 2nd one.My questions are: how do I do it? When I try to create a RAID set in the Disk Utility GUI, it says all data will be destroyed. I cancelled that.So I tried diskutil enableRAID mirror disk1, which told me I could only mirror volumes.The volume name is RAID, so I tried diskutil enableRAID mirror /Volumes/RAID which gave me an error "Error enabling disk to RAID Could not unmount disk (-10000)"

I am using a 2006 Intel Xserve (10.6.8) at home for storing lots of multimedia. My 2 TB user drive, which is inside of one of the Xserve's drive caddies is nearly full. I purchased a $157 3 TB Seagate Barracuda (Model No. ST3000DM001) from Amazon and put it inside the caddy. It is not being recognized at all. Looking around for solutions I am getting a hint that trying to restrict the data rate to 1.5 GB/s might help, which is documented for some of Seagate's older SATA drives, where one puts a 2-mm jumper clip on a header next to the SATA connector. This 3 TB model has the same header, but the manual only speaks of data rate autonegotiation. I'll be able to try out the drive with the jumper clip in place tonight and will report back. Curiously, in my Thermaltake USB-2 interface (toaster style), Disk Utility shows the drive as "801.57 GB Generic External Media," which is being discussed in a Leopard Server discussion thread. Last I saw, there was no good explanation for this symptom.
