10 | * A.V. Le Blanc (LeBlanc@mcc.ac.uk) wrote Linux fdisk 1992-1994, | |
11 | * patched by various people (faith@cs.unc.edu, martin@cs.unc.edu, | |
12 | * leisner@sdsp.mc.xerox.com, esr@snark.thyrsus.com, aeb@cwi.nl) | |
13 | * 1993-1995, with version numbers (as far as I have seen) 0.93 - 2.0e. | |
14 | * This program had (head,sector,cylinder) as basic unit, and was | |
15 | * (therefore) broken in several ways for the use on larger disks - | |
16 | * for example, my last patch (from 2.0d to 2.0e) was required | |
17 | * to allow a partition to cross cylinder 8064, and to write an | |
18 | * extended partition past the 4GB mark. | |
19 | * | |

20 | * Karel Zak wrote new sfdisk based on libfdisk from util-linux |
21 | * in 2014. | |
