[Bug 321544] Re: Persistence Slider Wrong; Takes more than 3 hours to produce largest persistence file

1M blocks work very very bad for me - it overloads the CPU but creation takes forever on a 4G thumbdrive through a non-highspeed USB connection. Worse - I can't stop the process because stopping the USB creator or even killing dd doesn't clear the kernel buffers that are used in the transfer. If I

[Bug 321544] Re: Persistence Slider Wrong; Takes more than 3 hours to produce largest persistence file

This is fixed in Karmic. usb-creator calls dd with a block size of 1MB. ** Changed in: usb-creator (Ubuntu) Status: Confirmed = Fix Released -- Persistence Slider Wrong; Takes more than 3 hours to produce largest persistence file https://bugs.launchpad.net/bugs/321544 You received this

[Bug 321544] Re: Persistence Slider Wrong; Takes more than 3 hours to produce largest persistence file

I didn't actually apply these patches directly. I updated mine (0.1.15) manually. Read the man page of dd. The size of the file that dd creates is equal to the product of the blocksize and the count. In the 0.1.11 the block size is 1 byte and the count is 'persist' (ie the number of bytes you

[Bug 321544] Re: Persistence Slider Wrong; Takes more than 3 hours to produce largest persistence file

I am using the jaunty 9.04 beta live DVD to create a persistent USB stick. Usb-creator is trying to create a single large block and is failing as a result. Block sizes = 2G aren't allowed by dd. Here is the error in my .usb-creator.log when I tried to create a 3.9 GB file: ['dd', 'if=/dev/zero',
