Unable to access Arch partition from Windows XP

Hi,
My laptop has got 5 partitions.

sda1 Win XP
sda2 Arch Boot partition
sda 3 Arch root partition
sda4 Arch Home partition
sda5 swap partition.

I have installed a few software to access linux partitions from within XP eg: Explore2fs. However all of them only seem to read the boot partition ( sda 2 ) and none of the others. It does not give me any error message.
The same program worked when I was using Ubuntu. Is there some difference between the two that does not allow the partition to be accessed?
Any advice,please?
Thanks
Samsom

Re: Unable to access Arch partition from Windows XP

Maybe:
Your boot partition uses ext2/ext3. Other partitions use ext4.
Explore2fs supports ext2/ext3. Therefore it can't read an ext4 partition.

Re: Unable to access Arch partition from Windows XP

I'm not sure if that is related, but your partition scheme is impossible: You must have an extended partition somewhere, and it's not listed.


Good ideas do not need lots of lies told about them in order to gain public acceptance.

My boot partition is ext2 and the rest are ext3 partitions. Like you say, that might be the problem. Let me see if there is any software for accessing ext3 partitions.
Thanks

What about Ext2IFS?

Re: Unable to access Arch partition from Windows XP

Perhaps it's inode problems, if your partition(s) using ext3 with => 128 inode, then explore2fs cannot read. Better asking explorer2fs dev to updating their software.
Correct me if im wrong smile

Re: Unable to access Arch partition from Windows XP

Post output of following commands, fdisk -l /dev/sda and mount. Run fdisk as root, mount can be as regular user. Incidentally, are you using LVM or some other setup which might hide your partitions?

Re: Unable to access Arch partition from Windows XP

None of the current Windows ext* readers support ext4 unless you disable some stuff when making the ext4 partition.

But mine are coming up as ext3...so not sure why they are not being read.

Re: Unable to access Arch partition from Windows XP

Personally I would far, far rather do it the other way around - ie access your ntfs-partition from linux, you can both read and write with no problems - and you could always make a link from /win/xp/Users/$USER/My\ Documents (or whatever) to (say) $HOME/documents ... just my own 2c-worth, and the reason:
1) for windows to read linux, you need something 3rd party (which usually costs $$$) and you dont know what you are getting
2) linux can read and write ntfs almost out-of-the-box (depending on which distro you use, you _may_ have to install ntfs-3g)

Re: Unable to access Arch partition from Windows XP

you can't use any driver for windows to read any ext2/ext3 because now every distribution is using as on option for ext2/3/4 inode size of 256.
those drivers for windows are capable to read ext2/ext3 only if the inode size is 128.


Give what you have. To someone, it may be better than you dare to think.

You're not or it would have come up in the output.

As others have been saying, those drivers do not support inode sizes greater that 128 bytes (as indicated on their FAQ under What features are *not* supported? If you're curious about your inode size, run dumpe2fs /dev/sda3 | grep 'Inode size:' as root.

Re: Unable to access Arch partition from Windows XP

been there, done it, hated it - EXT windows drivers never really worked reliably - if you MUST share data between Windows and Linux, use a NTFS / FAT32 partition for it, same for external harddrives ... all my USB hd's are NTFS and I never had an issue with any recent Linux distribution !

Its 256. Is there no hope then?

Re: Unable to access Arch partition from Windows XP

I am going to install Windows 7 soon on my other hard drive.
What you can do is to add it to a virtual machine program (raw disk access) and use its share files feature to manage files across both OSen.
