Software:

libfs is a library for IRIX/SunOS/WinNT which lets you read SunOS big endian UFS filesystems on SunOS/WinNT an IRIX EFS filesystems (like the CD used for IRIX software installers) on IRIX/WinNT.

• libfs source code
• REAME for EFS
• REAME for UFS
• winefssh.exe A minimal shell which let you read EFS on NT
• winufssh.exe A minimal shell which let you read UFS on NT

Usage:

In order to use win[eu]fssh you should pass it the device name as argument.

• Solaris 2.x -> ufssh -p0 /dev/rdsk/c0t0d0s2
• SunOS 4.x -> ufssh -p0 /dev/rsd0c
• WinNT -> ufssh -p0 \\.\PHYSICALDRIVE1
• WinNT -> efssh -p7 \\.\PHYSICALDRIVE1
• IRIX -> efssh -p7 /dev/rdsk/dks1d4vol

Note: on WinNT, you will have to guess the number after "\\.\PHYSICALDRIVE" for your device.

On Windows XP it seems the device naming scheme is different, so, for instance, CD-ROM is \\?\Device\CDRom0 and it may need some specific block size instead of winefssh default one.

For instance, on a Windows XP Pro SP1 system with DVD drive I had to use:

dd if=\\?\Device\CDRom0 of=cd.efs bs=4096
winefssh -p7 cd.efs

where "dd" comes from http://uranus.it.swin.edu.au/~jn/linux/rawwrite/dd.htm

There you may find some tips for guessing the name of the device you are looking for.
