executable doesn't work on 2.5" USB2.0 HD

Hi folks,

I bought a 2.5" 80G USB2.0 HD and partitioned it into two 40G partitions, NTFS and EXT3 respectively. I mount the EXT3 with the following command:

Code:

mount /dev/sda2 /mnt/usb2

I also made myself the owner of /mnt/usb2, thus, I am able to read, write and create files in /mnt/usb2. However, I encountered an odd problem when I was setting up a cross-compiling environment, that is, I can not do "make menuconfig" in /mnt/usb2. I got the following msg and the console just went freeze:

Code:

make menuconfig
rm -f include/asm-arm/arch include/asm-arm/proc
(cd include/asm-arm; ln -sf arch- arch; ln -sf proc- proc)
rm -f include/asm
( cd include ; ln -sf asm-arm asm)
make -C scripts/lxdialog all
make[1]: Entering directory `/mnt/usb2/home/cyu021/Desktop/eos/research/implementation_dvs_io_rt/microtime/s3c2410/linux/scripts/lxdialog'
make[1]: Leaving directory `/mnt/usb2/home/cyu021/Desktop/eos/research/implementation_dvs_io_rt/microtime/s3c2410/linux/scripts/lxdialog'
/bin/sh scripts/Menuconfig arch/arm/config.in
Using defaults found in arch/arm/defconfig
Preparing scripts: functions, parsing............................................................................done.

Neither can I run any executable resides in /mnt/usb2, I got permission denied regardless I log in as a regular user or root (doing "su").

Here is some info about my working environment:

Code:

You will probably need to fix your /etc/fstab file, or add more parameters at the time mount which is "exec".
By default the drive is added in a manner where no executable files are allowed any permission. And no matter which user you run as it will not work. Here is a line from my fstab which might give you a hint as to what to do.

/dev/sda1 /usbdrive auto rw,noauto,user,exec 0 0

I am not sure how you'd do it from the command line

Hope this helps

YUPIE! The "exec" part works smoothly.
You just saved me lots of trouble from moving data around all the time, thanks for the help :-)
