First, i apoligize if i didn't do the thread right.. first time on tomshardware.
i have been running windows xp and just decided to also run ubuntu to see how i like it. i went through the setup and i came to the part where i had to partition my harddrive. i already had c-30gig and d-30gig with d being completely free. here is where i made my mistake. i partitioned d for the ubuntu but instead of doing all of it i selected about 3gigs. i thought this would allow me to run ubuntu and still be able to access the c and d. once i did this it put the remaining part of d as free space. now when running out of xp or ubuntu i only have the c drive. i know the space from the d drive is still there but i dont know how to get it back. if i need to explain better please let me know and if anyone has any ideas of getting the drive back on i will really appreciate it..
In windows XP, right click on the My Computer icon (on the desktop or in the start menu) and say 'Manage'.
Select Storage -> Disk Management (Local).
This will show you the drive and the partitions.
Right click on the unpartitioned blank space and say 'New Partition'.
If you format that partition as Fat32, both XP and Ubuntu can see it. Ubuntu had some troubles with NTFS which can screw up data although it might have been fixed now.
All the best.
Eru is right on as for how to fix the problem. If you are using Ubuntu 7.10 it is supposed to have fixed its NTFS issues and is supposed to be able to use NTFS natively. I haven't had a chance to test that yet though.
