I need to copy a file into a Flash memory which is connected to my computer via USB. The file must start at a specific sector.
Can anyone guide me how to do this? (it can be through a C program, a line command, or any other way)
I was attempting to reformat a 16GB MicroSD card in my camera when the battery died mid-way. After that, any time I try to read the card in my camera, it gives me a "Card Error" and does not allow me to reformat it in my camera.
So, I thought I would plug the camera in to the laptop with it set to host the card as media when plugged in as USB, in an attempt to fix the formatting issue.
However, when I plug it in to my linux machine, it does not register as a device (e.g., /dev/sda) due to some errors, therefore I cannot reformat it. Essentially, I think I need to fix the partition table but I'm not sure how to when it doesn't register as a device. code...
I am a beginner with php ,trying to work my way through.

I need a way to get Kickstart to start on a on a specific sector. For example you can do this using parted
parted /dev/sda
(parted) mklabel gpt
(parted) unit s
(parted) mkpart primary ext2 40 -1
This will start a partition on sector 40. How can I do this with a kickstart file?
I'm writing a C program that reads the boot sector of a USB disk. (it is mounted as /dev/sda1). I'm able to read the sector, by the calls code...
The problem is when I wish to write. I use the call:
bytesWrite = write(fd, buf, 512)
The 'write' returns the value of 512, which looks as if the write was successful, yet
when I read again the /dev/sda1 device, I see that no writing was actually made.
Can anybody tell me what do I need to do in order to allow an actual write to the
device?

Terribly new to Linux and find it mindboggling. I work on brain imaging and unfortunately all of the analysis runs on Linux, and I do not understand computers well coming as I do from a medical background. So my question - There are various folders of patient MRI scans (folders called P1, P2, P3 etc) and within them are enclosed certain files that I am interested in (always called the same name in all folders, say image001). I would like a script that enables me to copy and move this image001 in all these individual folders to another folder altogether.

View 14 Replies View RelatedI've been reading for a while about samba but I haven't found a solution to my problem yet.I'd like to know if, the configuration I have in mind, is possible at all ("security = user" is what I'm using now).I want a directory to be:
1) read only for guests and some UNIX users;
2) write for some other UNIX users.
The advantage of this configuration would be that every single user in my LAN (with or without a UNIX account) would be able to read the content of the shared directory Music and I (UNIX user andrea) could manage the folder directly trough samba preserving the correct owner/group and permissions on the new files/folder created.
Notes about my configuration above:
1) as it is now every user gets authenticated by samba as nobody so even I (andrea) cannot write in it;
2) commenting out the line "guest ok = yes" I can authenticate as "andrea" and write in it but guest access is not possible any longer.
