Re: burn iso to usb
Guys and girls: Thx a lot for crash course/s! I have to let it go a bit; pretty extreme learning portions here. My head gets all wired up. But I have to go this track; for me it's all in the terminal; it's more accurate, always works,& faster. And I remember it way better.

[ I'm glad my silly intervention brings up a more constructive discussion ;-) ] If they're both pretty much constant, they're presumably both pretty much equal, so it doesn't matter which is which ;-) But indeed, it's not always the case. I'm right now using `pv` to read data off of a broken drive (a 2TB 2½" drive which apparently has problems seeking, resulting in a transfer rate of about 45kB/s), and it's currently showing me 45.0KiB/s and 70.6KiB/s both of which are quite stable. If it weren't for the first sometimes changing to 44.xKiB/s it'd be hard to know which is which (IIUC the average is higher because occasionally the drive gives a more reasonable transfer rate than that measly 45kB/s).

Another nice use for 'dd', btw :-) pv -parle < ... | sudo dd of=/dev/sdb One charming property of that is that only the 'dd' runs as root.

Re: burn iso to usb
Hi. The different suggestions are not complete, are they?? Like: pv -parle /dev/sdX would rather be: sudo pv -parle /dev/sdb And even not sure on that example as being correct. Please correct my possible failure/s in the above try. As you can see, I`m trying a -64bit- because Macbook 2.1 might fit it. And Gnome because it seems more complete. Saw another (relative) newbie said something similar concerning man pages in terminal: "Would be nice with example/s".

Writing "quite stable" cloaks the information nicely. The average can never move away from the rate: a change in the least significant digit gives the game away. > If it weren't for the first sometimes changing to > 44.xKiB/s it'd be hard to know which is which (IIUC the average is > higher because occasionally the drive gives a more reasonable transfer > rate than that measly 45kB/s). So now we're left wondering how you came by this situation. Perhaps you slumped onto the Return key, then woke up after a few minutes, having missed the initial burst that gave rise to the average being more than 50% faster than the current rate. Cheers, David.

I guess it depends. Before that comment I tried it on an old USB stick. Read speed was pretty much constant if low. So I think it was the left rate counter that showed current rate but wouldn't bet on it.

Re: burn iso to usb
Hi, was https://www.debian.org/CD/faq/#write-usb already mentioned in this thread ? Besides the already mentioned Unix methods it gives advise for users of MS-Windows, to which i would add program Rufus and its "dd" mode.

I tend to use 1M, because it's easy to memorise :) For the finer operations with ISO images i prefer bs=2048, because that is the natural granularity of ISO 9660 filesystems.

Just: cp /path/to/file.iso /dev/sdX where sdX is the device for your USB drive. You will need to make sure you have the permissions for the devices; I advise it over using rood privileges for the cp: you could wipe your install if you get the device wrong.
