Read Linux filesystems from Windows

I have a linux ext2 formatted external disk from which I wanted to transfer some files to my Windows PC. I came across Ext2 IFS for Windows on which does this. This program is freeware. However, this program was unable to read the file system. So I googled some more and came across explore2fs. I tried the 1.07 version which is stable and voila, I could read the external disk. I exported all the files from that disk to Windows PC. The makers of explore2fs have also come out with Virtual Volumes. This is still in beta. A copy paste of the current features and future planned features of virtual volumes:

Current Features of Virtual Volumes:
  • Supported by all versions of Windows (Vista is still Work In Progress)
  • Read and Write LVM2 (linear stripes only)
  • Read and Write EXT2/EXT3 (e2fsprogs/libext2fs)
  • Read ReiserFS (rfstools)
  • Read and Write Win32 filesystems (Win32 API)
  • Read FAT12/FAT16/FAT32 without using Win32
  • Read and Write software RAID0, RAID1 and RAID5
  • Read and Write via SFTP
  • Read and Write VMWare disks
  • VFS allows mounting on subdirectories
  • VFS abstraction allows multiple filesystems to be supported
  • VFS abstraction allows network filesystems like ftp, http and scp to be supported
  • Command line interface
  • Drag & Drop GUI
  • Auto detect available filesystems for GUI quickstart
Planned Features of Virtual Volumes:
  • More filesystems (HFS, ISO9660, NTFS, ...)
  • More file based filesystems (.zip, .tgz etc)
  • Accessable in native namespace to give filesystem drivers access to LVM2 and RAID
  • NT Kernel driver to enable IFS to read LVM2
  • Apache module to make Virtual Volumes available via WEB-DAV. This will allow Windows to assign a drive letter to Virtual Volumes.

XP setup hangs on Setup is inspecting your hardware configuration screen

A few months back I had installed Fedora 7 on a laptop to see if everything I do on Windows can be done on Fedora too. I have not figured out a way to make Nortel VPN work on Fedora yet. Open Office is good but not 100% compatible. So I decided to remove Fedora and install Windows XP on this laptop. Strangely the setup did not proceed beyond the message "Setup is inspecting your hardware configuration" screen. I googled for this and found this link. It suggested that if we remove the existing partitions on the disk, the XP setup would proceed smoothly. I had assumed that XP setup would recognize the Linux partition and I could remove it during the installation. But XP setup failed to do so. The link had suggested booting through a linux CD to remove the partitions, but I decided to do it through good old DOS. So off I searched for a DOS bootable CD image which I found here. I burnt the CD and booted the laptop through the CD. I removed the existing partitions through FDISK command. Windows XP setup continued without issues when I tried to install it after removing the partitions.

Please insert a disk into drive

Currently, I am on vacation, that's why the blog is not being updated regularly. When I tried to use a CD-ROM in my laptop, it gave the message:

Please insert a disk into drive E

I thought it was strange because the drive was working fine back home. I used some rectified spirit to clean up the lens, as I thought it may be due to dust on the lens. However the drive refused to read the disc. Googling, I found that some people had received this error on desktops when the wire connections of the CD-ROM drive were loose. So I ejected my CD/DVD drive from the laptop and inserted it again. Voila, now the CD-ROM disc I was trying to use worked.

A very simple solution to a problem which may have led to purchase of a new CD/DVD drive.
