crash on ext3 access

I am using Windows 7 32bit and I also have Ubuntu installed on a seperate partition and I can read files in the ext3 partition, I can save downloaded files to it also, however ocasionally the blue screen will come up when I browse to the disk and try to open any file. As soon as the file gets highlighted the blue screen comes.. what could be the problem?

I am using ext3fsd which works in vista so it worked in windows 7. Disks are mounted at start up but ocasionally blue screen

either

I've found that ext2IFS is the more solid program to access ext3.

However, it only supports an ext3 inode size of 128, which means that you have to format the partition as such before installing Ubuntu - the Ubuntu installer uses inode size 256, which ext2IFS cant see.

Use the following command in terminal (which you can run from the Ubuntu live cd:
mkfs.ext3 -I 128 /dev/sda[your partition number]

to create the 128 inode ext3 partition, before running the Ubuntu installer.
Install ext2IFS from windows, and then use the mountvol command from windows to keep the ext3 partition in my computer after next reboot.

I haven't had a crash or a blue screen yet

Agreed with Petejk (nice post)

+1

Ext2IFS is great, I haven't tested on the latest build but normally one has to install using vista compatibiltiy mode (I used SP1)

Also I noticed probably because of the UAC or something for most of the windows 7 builds on startup your drive is not automatically mounted to the drive letter chosen again. Tend to have to open the control panel item and reassign a letter every time.

To keep the drive letter assigned to the volume, open cmd, and type
mountvol d: /L
where d: is whichever drive letter you assigned to the ext3 volume with the ext2IFS control panel app.
it'll then stick after the next boot..

Sorry about this old thread
I installed ext2IFS the way petejk said to do in post # 6 & it worked.
But I tried the mountvol (drive #): /L in cmd & it does not mount the drives (y & z) at startup does anyone know of a way to make it mount at startup?
Thanks Jerry

Edit: It's on a desktop with Window 7 Pro 32 Bit

Try this,

cmd
mountvol (drive letter: ) /L

I got

mountvol e: /L (e: is my ext3 partition)
\\?\Volume{7b57b5c0-b2f9-11de-b93e-806e6f6e6963}\

(this gave me the partition UUID)

Create a .bat file
mountvol E:\ \\?\Volume{7b57b5c0-b2f9-11de-b93e-806e6f6e6963}\

save the file and the drag it into your start menu startup folder.

partition will now mount on windows startup - only annoyance being a cmd window appearing every time you start windows.

Hope this helps
