OS X :: Flash / Thumb Drive Not Work In Windows Or Ubuntu
Jan 29, 2010
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'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.

So my Mac froze for some reason, while my Kingston thumb/flash drive was in. I tried to eject it, but I could only force eject (which it said may cause issues). After that, whenever I put the thumb drive in, it said something like the drive won't work and I had to copy the files to my desktop. When I go into disk utility and click repair disk, it says this: "Disk Utility stopped repairing “UNTITLED 1”: Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files." I can't erase the thumbdrive, because it says I need a source, which I don't know what that means.The files are useless now as I have transferred them to a CD, so I'm fine with erasing the whole thing.

Mac mini, Mac OS X (10.6.5)

I have an Aluminum MacBook, is it possible to install Windows with boot camp from a thumb drive? I have access to the ISOs I need (from MSDNAA), but I ran out of CDR/DVDRs. Ideally I would extract the ISO onto the thumb drive and have it behave the same as if it was a CD, is it that simple or is there something else I will need to do?

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 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?

I have/had a 16 GB Kingston Data Traveler flash drive with all of my work files on it. I travel a lot for work and I was just in Italy for 2 weeks. Anyway, I went to an internet cafe to print a document before a meeting. 20 minutes before I went to this place the drive worked fine. I got to the place, and it seemed to me that the guy didn't know what he was doing. He had machines running on XP and they were extremely slow, and he just kept clicking away. He finally turned to me and said that his machine wouldn't read my drive. I blanched and tried putting it back into my Macbook and felt sick when I saw that the drive was no longer recognizable on my Mac either.
I had backed up almost everything on the server before I left for Italy, and I had emailed most of the new documents I had created while away from the office. Unluckily, there was one folder of documents that I hadn't backed up on the server because there wasn't enough space there (grrr), so I had left them on the drive. A few lessons I learned:
-back up on the desktop or hard drive as well while traveling
-bring the portable printer next time
-don't let someone mess with my jump drive
Should I reformat the drive and attempt to use it again, or should I buy a new one that is a better brand? I definitely don't want a repeat of this. This is the first time I've ever had a problem like this--all the other drives I've ever used, from expensive to cheapies, all worked fine. Is there any way to recover any of these files or should I just accept that they're gone? My guess that being an internet cafe with PCs, the computers were full of viruses and the drive became infected corrupted. When I try to repair it or verify it, I get an error message.

I work for a post secondary school with online formatted classes. We send flash drives out to students to access video content when they are on the go, but it was pretty much made for Windows based computers. I have had a few students now who have Macs and cannot open the content or are getting a message stating the drive is not formated. I see many instructions on how to format a flash drive from a Mac to work on a Mac & PC but nothing about being able to format the flash drive using a PC so it can work on a Mac.

Dell, Windows XP Pro, Windows 7

I am here because I am interested in buying my first Mac Laptop. I would be mainly using this in my High School during Lunch and Study hall to work on projects and research. My school only uses Apple computers so I don't think there will be a networking problem(heard there can be some unfriendly networks towards macs?). I have been looking into THIS I Book sold used by [URL]it dose not have a airport card (I dont know what that is) and the CD drive doesn't work but that doesn't bother me because I mainly use flash drives and SD cards.

I have installed ubuntu on a partition on my uMB and I am having trouble getting some features like two finger scrolling and right click on the trackpad as well as getting the bluetooth to work to be able to pair with my wireless mighty mouse. Also the speakers do not work. My priority is getting the bluetooth to work because If I have a working mouse the trackpad won't really matter. When I try to pair my mouse with the bluetooth I can see it but when I enter the "0000" passcode and click connect it says connection failed.

possible it install Windows using a USB Flash Drive configured to function as an Install Disk? Using the generally accepted method for converting a USB flash drive to act as an installation disc my 2010 iMac 27 will not recognize this drive using the boot drive 'option' key method. After formatting the drive as an MBR disk to act as in installer the iMac will not recognize it as a bootable drive. This works fine on other Intel based computers and my GUID USB Flash Drive OSX install image works just fine and is recognizable as a bootable drive.

I am trying to install windows 7 to my bootcamp partition from a USB flash drive. I looked up some other forums that talk about how to do this but they started throwing in all kinds of fancy computer terms that I don't understand.

Will use a USB flash drive (memory stick, etc.) to move files from a Win 98 PC to a Mac Pro.
-- PC has FAT32 file system
-- Mac Pro has journaled HFS+
What gotchas should I watch for?

Just a quick question regarding bootcamp and windows installation. I have windows XP burned onto a disc with a few other programs so when I have to insert the windows disc will that work? Or would I have to burn it to a dvd by itself? Will windows install off a flash drive maybe? Also, When it asks for the MAC osx disc, can I just use the install discs that came with my new MBP?

I created a Ubuntu VM on my mac and installed the VMWare tool stuff. Now the mouseover thing and auto screen resizing works, but I can't copy and paste files into my VM...
Is this impossible with Linux or did something go wrong when installing it?
Also, visual performance is really poor, when I drag a window around it moves at a very poor framerate. In Windows XP this is also the case but not as badly, can something be done to improve either of these problems?

I have a 2.33ghz intel Macbook Pro from 2006, version 2.2 I believe, formally running snow leopard. So yesterday my HD crashed, so I am attempting to use a Ubuntu Live Cd (I also have Knoppix too) to just see the HD and attempt to pull a few key files off the drive. The problem I'm having is that I put in the CD/DVD (I've tried both the Ubuntu CD and the DVD one found here, http://cdimage.ubuntu.com/dvd/current/, and Knoppix 6.2.1 CD)
Boot, Immediately press "C" or "Option/Alt", and it does NOT see a CD/DVD.
I tried inserting the snow leopard disk, and it will "see" that, (I am able to use disk utiltiy ect, off the disk), so I know that the DVD drive is working, and that I am at least doing the process of getting the computer to boot of a CD/DVD correctly.
However when ever I put any of the ISO burnt CD/DVD operating systems I have tried it doesnt "see" anything.
(I have tried a knoppix 6.3.1 CD, burnt off a windows machine, a Ubuntu live CD, burnt off a windows machine, and the same Ubuntu live CD, burnt off a mac, and now I'm downloading a Ubuntu Live DVD, and will burn it on a windows machine)
So my question is does anyone have any idea why its not recognizing any of these ISO burnt CD/DVD operating systems?

I'm going to buy an AirPort Express soon and I was wondering if it works fine under Ubuntu Linux 8.10.
Also, I have my hard drive partitioned and one side is Windows and the other is Linux and if I install AirPort Express under Windows and setup the setting and all and I boot to Linux, will the AirPort Express still be working or will it only work if your under Windows?

Would it be possible to install Windows (7) for BootCamp from a USB Flash Drive instead of burning it to a DVDROM?Installing Windows (Vista) from a Flash Drive [URL]is possible and potentially faster than installing from DVD or ethernet. I'm assuming this should work for Windows 7 as well.So the question that remains is if BootCamp can boot? install from? USB. (I've never tried BootCamp, so I'm not familiar with the process of even starting an install.)
