This is indeed some issues with udisks failing do to things we ask it to, for various reasons. We're trying to fix this, but the issues are not all obvious or are hard to reproduce reliably. Seems at least part of it is due to how images get written when done with dd. > I have been helping people at the Ubuntu Forums for some years now, and > I have seen so many problems related to the SDC.

I keep recommending usb-creator too, and it works quite well for the majority of people. The thing with helping on forums is you're most likely to see only the "bad" side of things: people will discuss issues because they run into them, but (while I don't want to diminish the importance of what they are facing) they're often dealing with corner cases. > I don't think all these bug reports are written for fun.

I think that the method used and maybe also the That simply isn't true. There are relatively few issues in total with usb-creator if you look at the bug reports carefully enough. - erasing the disks is brittle. - creating amd64 images from i386 breaks. While I agree the first tends to be a recurring issue (we keep fixing it and it breaks again later), and the second one we introduced as an unexpected side-effect of fixing another bug, that's hardly "a lot". > programming language and programming style makes it too sensitive.

Relatively simple python at that too, otherwise my little brain would likely have a lot of trouble dealing with it ;) I feel it's quite approachable, the issue only being that due to wrapping other things, it's subject to it's dependencies breaking in fun ways. For example, since UEFI, we've effectively doubled the number of issues you could have related to formatting and partitioning -- you need to deal with the usual MBR partitioning, but you also need to deal with GPT (which seems to be what's causing issues now) > need major bugfixes with new versions.

We all have different views on it and varying use cases that don't tend to intersect. I use it regularly without too many problems (but like Marc, mostly on amd64), others may see a different side of it. It doesn't mean that it should be thrown away. The jist of it is: when you notice an issue, please file a bug. I for one don't spend *any* time on forums since I just don't have any time for it -- I can't know what people are reporting as issues there, and we need to bugs to be open in Launchpad anyway to be able to deal with them efficiently. For the time being, like I've expressed elsewhere, there seems to be no other project with is as reliable, as easy to use, and as easily maintainable. -- Mathieu Trudel-Lapierre <[email protected]> Freenode: cyphermox, Jabber: [email protected] 4096R/DC95CA5A 36E2 CF22 B077 FEFE 725C 80D3 C7DA A946 DC95 CA5A
