Limitations
Seagate documentation warns, "Certain disc utilities, such as DD, which depend on low-level disc access may not support 48-bit LBAs until they are updated." Using ATA harddrives over 128 GiB requires 48-bit LBA. However, in Linux, dd uses the kernel to read or write to raw device files. Support for 48-bit LBA has been present since version 2.4.23 of the kernel, released in 2003.
It is jokingly said that dd stands for "disk destroyer", "data destroyer", "death and destruction", "damn dangerous", or "delete data", since when used for low-level operations on hard disks, a small mistake, such as reversing the if and of (input file and output file) parameters, could result in the loss of some or all data on a disk.

Famous quotes containing the word limitations:
“To note an artist’s limitations is but to define his talent. A reporter can write equally well about everything that is presented to his view, but a creative writer can do his best only with what lies within the range and character of his deepest sympathies.”
—Willa Cather (1876–1947)
“Much of what contrives to create critical moments in parenting stems from a fundamental misunderstanding as to what the child is capable of at any given age. If a parent misjudges a child’s limitations as well as his own abilities, the potential exists for unreasonable expectations, frustration, disappointment and an unrealistic belief that what the child really needs is to be punished.”
—Lawrence Balter (20th century)
“The limitations of pleasure cannot be overcome by more pleasure.”
—Mason Cooley (b. 1927)
