[Bug 971033] Re: dd corrupts some .iso data resulting in corrupted file system

[Anadon]

"dd 
bs=100M if=/home/user/Downloads/target.iso of=/dev/sdb"

with and without sudo and with and without bs specified.  i checked my
.isos again and they have the correct checksum.

my usb drives included 1 lacie key usb drive, and 3 low profile sandisk
drives.

sorry for grammar.  Android touch keypads are terrible...

Title:
  dd corrupts some .iso data resulting in corrupted file system

Status in “coreutils” package in Ubuntu:
  Incomplete

Bug description:
  I have attempted to copy four different .iso's (and for a few, I re-
  downloaded and tried again) on 4 different USB drives.  Recently, this
  method of .iso copying no longer worked.  The data from and .iso I use
  is changed at some point resulting in a corrupted partition on the USB
  drive and an unbootable device.

  I have used as a normal user, sudo, default settings and tweaked.
  Nothing is working.
