The why behind this is a little long winded so let me get to the technical question. I have a 16 GB SD card in my netbook as additional storage to the 16 GB SSD drive. The SD card is formatted fat32 (by a utility from sdcard.org which is supposed to and does make the card read and write faster than if it was formatted by the OS). The card mounts when I login to the netbook. The entry from mtab shows
Quote:
/dev/sdb1 /media/SD16 vfat rw,nosuid,nodev,uhelper=udisks,uid=1000,gid=1000,shortname=mixed,dmask=0077,utf8=1,flush 0 0
If I look at the permissions on SD16 I find
Quote:
ken@taylor13:/media$ ls -l
drwx------ 3 ken ken 32768 1969-12-31 19:00 SD16
sudo chmod 777 SD16 does not change the permissions.
The problem is I need to connect to the machine with a different user (due to a security hole in gnome-commander). As the card is formatted fat I cannot assign group permissions to it and my second user cannot access it.
I had previously had the card formatted as ext3 and it was so slow as to be unusable. It needs to be formatted fat. I am stumped.
I've tried to search online but I can't find anything that works on our netbook. The netbook has a default Squeeze installation. After inserting the microSD card (via a "microSD card adapter" into the built-in slot), when I double-click on "Computer" on the Gnome desktop, it shows "Multiple Card Reader", but I can't access it. fdisk -l doesn't show any new devices, but dmesg does show the following:
[ 2532.101119] usb 1-5: reset high speed USB device using ehci_hcd and address 8
[ 2542.344135] usb 1-5: reset high speed USB device using ehci_hcd and address 8

I can't mount /dev/sdb or mount /dev/sdb1 (fdisk only shows "sda1-3"). The system simply reports that "special device sdb does not exist", although during one attempt I did get a message saying "block device sdb (or sdb1) something...".
It's imperative that I can access this microSD card. It will be put into my mobile phone so I can have the Star Trek: The Next Generation theme tune as the ringtone. I'm sure you all - as will all of humanity - realise the importance of this endeavour
I am using fedora 8 . Recently i have bring a DLINK ( DGE-528T ) LAN card 100/1000 that is giving problem . It is detecting so i have given ip address to that card and restarted services but its is not accessing internet.

I'm trying to install a SDK iso image onto an embedded linux platform. I was able to mount the image on the platform without problems. I also created a symbolic link called "bash" in the bin directory and had that point to busybox to satisfy the first line of code in the installer: "#!/bin/bash". However, when I run the installer, I get an error: "installer: applet not found"
I get the same error when I type "bash" on the command line. Is there a way to fix this? Here is the first few lines of code that causes the error:
#!/bin/bash
DEBUG=${DEBUG:="0"} # Enables debugging options
LC_OPTION=${LC_OPTION:="prompt"} # Licensing related variable
INSTALL_PATH=${INSTALL_PATH:=$HOME} # Default installation path
declare -r SCRIPT_NAME="`basename $0`"
declare -r SCRIPT_CALLED="$0 $*"

I need to use a language for doing simple things like tagging words and translating using a dictionary I am building. I am beginning to use AWK in conjunction with Bash and need to find some members with whom I can dialog on particular topics; even getting advice. Are there any AWK users in the community, using the language for processing text?

View 3 Replies View RelatedI need to transfer a 4Gbyte file from my Linux netbook to a friends WinXP desktop. And I'd like to it with a usb flash drive, but it can't handle a file larger than 2Gbyte. A limitation due to the underlying FAT32 filesystem. But I don't wish to reformat my usb as ext3 either.
So I need to split my 4GByte file into smaller chunks. And the 'split' utility needs to be available on both Linux and the WinXP operating systems.

View 8 Replies View RelatedI'm trying to run the kernel configurator for my embedded ARM platform (PXA310) but so far I can only get it to run for my build platform, an i386/32 machine.
