Sector by sector copy of one pendrive to another ?
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. Andy |

Most other Linux distros file systems are ext 3,4, and 5 if that makes any difference. Appreciate your feedback. Andy 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. http://www.chrysocome.net/dd 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.

Sector by sector copy of one pendrive to another ?
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.... Winimage for WinXP can be downloaded by clicking the link below: http://www.winimage.com/download/winima85.exe Winimage for Win9x can be downloaded by clicking the link below: http://www.winimage.com/download/winima60.exe == Cheers, Tim Meddick, Peckham, London. :-) "Andy" wrote in message ...

I am "cooking with gas right now. Take care, Andy |
