#1 u3-tool: Device reported command failed

Hi,

Mine is exactly Sandisk Cruzer Micro U3 4Gb. I remove the U3 partition using the windows tools, but now I need to re-enable the CD partition, but failed to do so:

# u3-tool -p 1 /dev/sdb

WARNING: Loading a new cd image causes the whole device to be whiped. This INCLUDES
the data partition.
I repeat: ANY EXCISTING DATA WILL BE LOST!

Are you sure you want to continue? [yn] y
u3_partition() failed: Failed rounding partition sectors: Device reported command failed: status 1

Here are more info about my U3:

More on dmesg that I should have included:

Forgot to mention my environment:

Using the latest u3-tool from Debian:

$ apt-cache policy u3-tool
u3-tool:
Installed: 0.3-1
Candidate: 0.3-1
Version table:
*** 0.3-1 0
360 http://cdn.debian.net testing/main Packages
50 http://cdn.debian.net unstable/main Packages
100 /var/lib/dpkg/status

BTW, found similar reports at

Have you tried using device sgx instead of sbx?

I recently restored the launcher on my older 4GB SanDisk Cruzer Titanium U3 device using these commands.

sudo u3-tool -p 25165824 /dev/sg2
sudo u3-tool -l cruzer-autorun.iso /dev/sg2

Note that the partition size I used matches that of the partition on the 16GB device that I sourced the iso from, likely could have reduced that size as the ISO was only about 7MB.
Then just ejected and connect to windows and ran the launch pad from the u3 cd device and it worked.

My attempt to remove the write protected partitions on a SanDisk Extreme Go using
u3-tool 0.3-3 on Linux Mint 20

$ sudo u3-tool -p 0 /dev/sdc

I got this error message:

u3_partition() failed: Failed reading device property 0x03: Header of property 0x0003 could not be read.

Despite the error message the boot sector was gone afterwards and the write protection on the second partition was removed. So I could use gparted to wipe the remainings and create a new partition.
