Sector by sector copy of one pendrive to another ?


A

Andy

I think the answer to this would apply irregardless of what o.s. is on the pendrive, but I may be wrong or am wrong.

Is it possible to do a sector by sector copy of one pen drive to another of equal or greater capacity ?

It is FAT 32 and has Puppy Linux on it.

Most other Linux distros file systems are ext 3,4, and 5 if that makes any difference.

Appreciate your feedback.

I've done it, so the answer is yes.

Use another OS, use a port of "dd".
For example, to copy my Ubuntu 16GB stick to my
new 32GB stick, I did that in Windows (while Ubuntu
isn't running), then used the Windows port of
"dd" to do the copy.

Note: dd version 0.5, does not detect the
end of a USB flash stick properly. If crafting
commands, specify both a block size (bs) and
count.

Example. I want to transfer 1,073,741,824 bytes of
data. I can specify that this way. This is actually
a one line command, but I did it this way to make
it easier to read.

dd if=<source file or partition>
of=<destination file or partition>
bs=1048576
count=1024

With that port of "dd", you open command prompt
and try out

dd --list

and it will tell you the names of the devices
and partitions. That's how you figure out how
to craft a partition (block oriented) reference.

*******

Linux does not mind, if you place multiple partitions
on a USB stick. You can use an MBR, use a copy of
Linux fdisk, and put four primary partitions on there.

When Windows sees that, it honors the first partition,
and ignores the other three.

I think it's also possible to put a file system on
a USB stick, without an MBR. So there are actually
some differences, when compared to a hard drive.
They don't work identically in all respects.

*******

Since you're copying sector by sector, it
really doesn't matter what file system is inside
the partition. It could be a FreeBSD file system
even.

You can do that in Windows, using the [free to use] utility: WinImage.exe

Choose the source/target drive to use, from the "Disk" menu, then use the
read (and Save As)/write commands to create a virtual disk image-file which
can then be used over and over to write absolute copies to
[identically-sized]
pen-drives as you like....

Vielen Dank.

I found a Windows .exe for puppy installation.

I am "cooking with gas right now.

Take care,
Andy
