Floppy & CD Tools:

Useful programs or utilities that fit on a single 3.5-inch floppy disk or bootable CD-ROM.

  1. MEMTEST-86 - Memory test program for x86 computers. Now included on many Linux installation CDs, so you may already have it.
  2. Tom's Root/Boot - A bootable floppy containing a surprisingly complete array of Linux tools and utilities. This makes a great generic "rescue disk" for almost any Linux installation.
  3. GRML - My current favorite Linux rescue CD.
  4. RIP - (R)escue (I)s (P)ossible, another Linux rescue CD that may work better on some hardware.
  5. PhysTechSoft Disk Editor - A very nice disk sector editor with mouse support. Can be booted stand-alone from a floppy -- no operating system needed!
  6. Darik's Boot And Nuke - A bootable floppy or CD that securely wipes hard disks. Useful if you're concerned about identity theft or industrial espionage when discarding old hard disks or computers.
  7. Windows NT/2000/XP password and registry editor - A bootable CD with a password reset tool and offline regedit program. Linux based. I thought carefully about including this, because it has questionable uses. Just like a locksmith sometimes needs a set of lock picks, however, there are times when a system administrator really needs this tool.

  9. How to fix a corrupt FAT32 boot sector - alternate method using PhysTechSoft Disk Editor.
