Removing Chrome Flow from a USB device.


I recently tried one of Hexxeh's build of Chromium, Vanlla. Of, course it didn't work because of my Wireless card, so I tried to do the same fix that made Ubuntu worked, which was putting a file full of drivers in the /lib/firmware . It didn't, however, work in Chromium. Since nobody helped me on the forums (Here) I want to delete it from my USB. I don't know how though, because when I plug it into Ubuntu it shows it as 3 different devices, instead of one, and I don't know which one to format.

What does fdisk say about it? Delete the partitions and then format would be my guess. Gparted might be fine too.

I have used a few of the live usb creators. Can't say why it seems to change the partition table so. In any case to return it you'd need to delete them all not select one.

When I tried GParted the first time, with the USB already in, it wouldn't run. Then I tried running it without it in yet, it wouldn't detect it, and now it won't mount the USB. I used Disk Utility to see it and it said there was 13 different partitions on the USB all of different types and sizes. Results of fdisk:
Code:
jetso@Jetso-Inspiron-1525:~$ sudo fdisk -l

What should I do? Will I ever be able to use the USB for starage?

You do know that you are looking at your installed hard drive and NOT just your usb.


" Device Boot Start End Blocks Id System
/dev/sdb1 1 229 1845265+ ee GPT
Partition 1 has different physical/logical endings:
"

sudo fdisk

Then select your sdb.

!!! be sure you know which drive you are on!!!!



Then delete the partition.

Then make a partition.

Then format it.


If you are unsure see this.

Unfortunately not everyone just sits around and answers questions all day long. Some of us do hold jobs too I am one of those.Why you did not get help earlier may have been few people have run into the problems you are having.

you gotta dd the drive, then use Gparted
be very careful with dd too

dd if=/dev/zero of=/dev/sdx bs=512 count=1

so if usb is sdb1 you would put of=/dev/sdb
not /dev/sdb1

that will completely wipe the usb
then use Gparted and it will say you need to create a new msdos filesystem
do that then format it fat32, set boot flag etc

dont dd your hard drive!

@tiredofbilkyyaforallican Sorry, I tend to be a little impatient.

Okay, so if the USB is sdb then I run
Code:
dd if=/dev/zero of=/dev/sdb bs=512 count=1
Right? That will not mess up my system? Then I format the drive a FAT32 for file storage right? As long as I don't screw over my hard drive, and have a USB system that I can store files in ans access from Windows AND Linux, then I will be fine. I want to check with you before I mess with anything. The drive is supposed to be 2 GB also.

Nothing happened... Here's what happened:
Code:
jetso@Jetso-Inspiron-1525:~$ sudo dd if=/dev/zero of=/dev/sdb bs=512 count=1
1+0 records in
1+0 records out
512 bytes (512 B) copied, 0.00209083 s, 245 kB/s
Any nothing is happening... Gparted still won't run while the USB is plugged in.

Oh! So your saying that I have to use Gparted to erase all the partitions, then format as FAT32? Gparted wouldn't load when I had the usb in, and when I unplugged it then started Gparted, my computer wouldn't see the USB...
