I plugged in a SDCard (SanDisk 4GB) with the write protect On in my Ubuntu system. Ideally this shouldn't have allowed me to write to this card. But it did. And that's when I found that it was getting mounted as a rw filesystem instead of ro. But the same card when I inserted it in another Ubuntu system with write protect On, this problem was not there. So nothing wrong with the Card.
View 3 RepliesI want to "write protect" icons on the desktop of a public computer in order to prevent them from being deleted.
What I don't want is those "lock" icons showing up overtop to show that the files are write protected.
I guess I could write protect the desktop, but I want to allow people to use it as a place to temporarily store files, and if files are downloaded there it makes them easy to see.
I am playing around with aircrack.

I am using OpenSuSE 11.0
KDE 3.5.9
Konqueror
I was able to copy 227 images to a brand new 2GB memory card and I am only using 8% of the card and now I can't write to it anymore?
Code:
Filesystem Size Used Avail Use% Mounted on
df -h returns this : /dev/sdd1
1.9G 136M 1.8G 8% /media/disk-2
This isn't the first time this has happened either. Just the last couple times I didn't really care enough to pursue it. But now I am trying to load a card for my daughters digital photo frame and I can't because now all of a sudden I can no longer write to the drive? The exact error message I get is: "Could not write to /media/disk/image.jpg" and when I try to create a new folder, I get a disk full error message? How in the heck is this possible when I am only using 136MB of 2GB of capacity?
Code:
mount
/dev/sdd1 on /media/E0FD-1813 type vfat (rw,nosuid,nodev,uhelper=udisks,uid=1000,gid=1000,shortname=mixed,dmask=0077,utf8=1,showexec,flush)

The micro sd card mounts & works as fat32 in windows xp just fine.
I have a USB stick with a mechanical write protection (a small switch that disables writing on the stick). I have installed Ubuntu 10.04.1 on this device usung the startup drive creator. If the switch is in the position that allows writing, Ubuntu boots as expected. But if I switch to write protection, I only see a blinking cursur. Because it is a live system on the stick I expected that it should work as well, because nothing should be written to the stick. Does anyone have an idea why it behaves like this and how I can change it?
View 9 Replies View RelatedI am using Sandisk 2GB micro SD card on ARM processor EP9307A. The card is detected, mounted.
I can read data from the SD card. But cannot write to it. There is no error when I attempt to write to the Card. It appears as if its working fine. But after umount and re-mount, the data written is gone.
Here is the log when the SD card is detected:
# insmod drv
card size = 1977614336, sector size = 31, wp_grp_size = 127, wp_grp_enable = y
S:00001000 M:fffff000
What is the significance of Write Group Protect Enable (wp_grp_enable=y). Is it the case that the SD card is write protected.
Using CMD9 : SEND_CSD , I can read the Card Specific Data (CSD).
I have tried CMD27 : PROGRAM_CSD , to CLEAR wr_grp_enable : No effect seen.
I have tried CMD29 : CLEAR_WRITE_PROT ,: No effect seen.
Where is the issue,
1. I could not send commands properly.
2. Card cannot be set free from WRITE_PROTECT.
3. Something else.
I am trying to write a kernel module that will DMA my custom card. Right now when i plug the card into linux no valid PCI device shows up (meaning I probably have a error on my end, i know) however, If I halt the system at startup in the bootloader (uboot) I am able to directly access the card as I know in uboot the physical memory address that is mapped to my device. Is there a way I can access the card in a simliar fashion in linux?
View 1 Replies View RelatedThe lock on the card broke off and I tried using tape in that groove, but is too thick for my camcorder. I navigated /media > Context Menu > Properties > Permissions tab > File access, and chose Read and write, but this didn't allow my camcorder to record with the card. Unless there's a way to unlock it with software, I'll try switching the insides with the casing of another. I just want to know what is the best type of SD card or Mini SD adpter to do the trick, i.e. what has the best lock.
View 1 Replies View RelatedI 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...

2. When I play and game the has 3d Modeling, it chops to about 3 FPS and is completely unusable. But heres the deal, I have a ATI Raedon X850XT Platinum card, which I know can handle it. I'm using Ubuntu 9.10 and have everything up to date.
My Canon PowerShot A470 + CHDK can write to SD-cards that are "locked" (the lock switch is used to make the card bootable), but GNU/Linux
`/dev/mmcblk1': Read-only file system
(I'm using "Texas Instrument 5-in-1 Multimedia Card Reader")
So I have to switch that switch on and off again and again. ("unlocked" to write to the card in Linux, "locked" to boot the camera from it).
How to force locked card to be writable in GNU/Linux?
I'm running Karmic Koala 64 bit on my Lenovo T400 laptop with switchable graphics having both Intel and ATI video cards. I've set my bios to use the intel card only and turned the automatic switching off. So far so good, but I'd like to turn on compiz for basic window animations. When I try to start compiz by selecting
Code:
"Appearance Preferences" -> "Visual Effects" -> "Normal"
I get an error message saying "Desktop effects cannot be enabled"
Code:
"System" -> "Administration" -> "Hardware Drivers"
doesn't show any new drivers that could be installed. This was working out of the box when I first installed Karmic Koala a few month ago, but things got messed up when I installed the restricted drivers for my ATI card. Now I can enable compiz if I switch to ATI from my bios settings and install the drivers but I don't want to use it due to high power consumption and I've removed the ATI drivers.
Here is my xorg.conf file:
Code:

Identifier "Configured Video Device"

I've star rated hundreds of tracks. All I want to do is write the 4* & 5* tracks to an SD card for use elsewhere. Banshee can use Brasero to write them to CD so at a push I could write a CD then copy it back to an SD card but that seems the long way round.

View 2 Replies View RelatedI have made a server using a bananapi. The bananapi is an embedded linux mini PC, using an allwinner A20 SOC. This server boots and runs from an uSD card, and logs data from sensors to an attached 1TB hard drive. This works OK, but the hard drive consumes a lot of power (about 2.5W), this essentially doubles the amount of power needed. I am planning to power this setup from an accu, therefore I would like to keep power consumption as low as possible.
I am planning to let the application log to the uSD card. After a while the uSD card is almost full. At that moment I can wake up the HD, move the data to the HD, delete the data from the uSD card, set the HD to sleep, and wait until the uSD card is full again. Is there some clever way to do this? I can do this with basic shell scripting, but then I get all kind of issues like open files that are copied to the HD while they are still being filled by the logging application. This would mean they end up on the HD incomplete.
The card in question is a PC Card (PCMCIA) 16Bit Intel Series 2 Flash Memory Card (2MB) and I want to be able to read from and write to the card.

The CF card in the adapter works. I'm expecting to see a block device in /dev but nothing appears lspci:

story is my brother is a dindows lover (gamer) and hes been gettin attacked by virus's,etc cause he runs his Vista setup with no firewall or antivirus
He says the firewall,etc slows down the PC too much for gaming He doesnt want to use Linux as his games wont play on Linux as on dindows
He wants to know if you can install a Linux firewall/gateway or whatever into his Linksys WRT54GC router and thus protect his PC without using a firewall or av in it.
EDIT: precisely; he has a Linksys wireless-G connected to a always-on Verizon Westel 6100G modem so its a wired connection, not wireless
