After a few experiments, it seems like roughly 2047MB is the limit for
how big persistence can be set to (it's somewhere in between 1025MB and
2047MB, this much I can confirm; I just tried it with 1GB and it worked
after two failures with 2GB), if it's above that threshold it just skips
creating
@Max:
Yes I can confirm I have the same problems trying to create a live-
persistent USB with a 4GB drive.

No persistence with USB Creator in Ubuntu 8.10

You guys can easily fix your problem by applying the patch in the bug I
linked to above: https://bugs.launchpad.net/ubuntu/+source/usb-
creator/+bug/321544. If you have the 2 GB (2048 MB) limit it is because
usb-creator is telling dd to make a single block that is 2048 MB.
However, dd will only
Blocksize is not the same as volume/partition/file size
(http://en.wikipedia.org/wiki/Block_%28data_storage%29). A file system
usually has a block size associated with it. In general terms, when data
is pulled off the device it will usually pull off the whole block at the
same time. Since related
Hi Jruss,
Why would it be bad to create a blocksize greater than 2GB? My usb is
formated in Fat 32, which is capable of handling volume sizes much
greater than that. Plus usb-creator doesn't complain if the format of
the drive is Fat 32 vs Fat 16.

No persistence with USB Creator in Ubuntu
I think the original bug report may be the same problem as
https://bugs.launchpad.net/ubuntu/+source/usb-creator/+bug/284085. If
the usb is using FAT32 (aka vfat) then there is a 4 GB file size
limitation, that can cause problems when creating a file casper-rw file
that is too big. The casper-rw
I think that some USB flash drives will work for this and others will
not. When I originally filed this bug report, I used an 8gig PNY
attache'
later on I tried with a 16gig Corsair flash voyager and it worked
fine... persistence and all.

No persistence with USB Creator in Ubuntu 8.10
I have tracked down a more serious problem. The current version of usb-
creator in jaunty beta tries to create the casper-rw file as one large
block, when actually it should use a reasonable block size like 1k and
then create right number of blocks. This is what is causing the dd:
invalid number
I guess they are planning on relying on the ext4 filesystem right? B/c I
think you can have huge single files. I'm not sure about that at all
though.

They will have to stick with FAT because that is what syslinux supports.
All modern file sytems including ntfs and ext3 already support files
larger than 4 GB. This most recent issue I brought up was the block size
which is different than the file size.

I repro the no persistence on several separate ubuntu machines. I
don't recall the attempts to write making the stick unbootable though.
Was using a 4GB corsair, freshly formatted fat32. ubuntu 8.10 and 9.04
