[SOLVED] How do you turn off write protection

LAPIII · 03-23-2011, 10:17 AM

I created a dump file to help troubleshoot an issue and I don't know what device this is referring to nor how to disable write protect. The line reads:

Code:

[    7.376548] sd 7:0:0:2: [sde] Write Protect is on

I will take a SWAG and ask if you have a memory card currently plugged into the printer. I assume all of the other removable USB devices are accounted for... If so check the RW switch on the side of the SD card.

There wasn't a memory card plugged into the printer. What did you mean if

What USB memory devices are connected to your computer. This appears to be your printer or a USB memory card reader. Unplug/replug the printer to see if sde disappears/reappears.

Without the majority of the devices plugged in, the mouse & keyboard are usb devices, I created a dump file,dmesg > dump.txt
and found a sde with different numbers:

Code:

[    7.143551] sd 4:0:0:3: [sde] Attached SCSI removable disk

The full file is attached. After plugging the devices back in, I ran lsusb and got:

Code:

Bus 002 Device 008: ID 046d:08ad Logitech, Inc. QuickCam Communicate STX

The first four and sixth of that list are my usb devices.

Do you have a memory card reader built into the computer?

Is there a memory card installed? Make sure it is not write protected.
