| Permissions question involving Windows XP.
So, heres the deal, I'm running SuSE 9.3 and Windows XP Home on one system, Dual-Boot.
Windows was getting messed up and one day died, couldnt start up, Linux, however could.
I was able to "see" the files on my Windows partition and saved the most valuable ones on my Linux partition before reinstalling Windows.
Now that Windows was working, I tried to put the files back onto windows, to find out that I dont have "permission" to put the files from my SuSE partition to my Windows partition.
Windows, being the restrictive OS it is, doesnt let me see Linux, so I can drag it from linux to Windows and whenever I try to go to properties and try to change the permission settings in Linux, it says it cannot change it.
What should I do to let Linux have permission to modify and edit my Windows partition? |

| This one might be tricky. Did you format the windows partition as NTFS?? It's normally formatted this way, in which case writing to this drive from linux is kinda dangerous, and has a high probability of data loss.
If you create a separate FAT32 drive, then this can be seen and written to by both windows and linux, so you'd be able to move your files back, and youd be able to share files in the future.

What should I do to let Linux have permission to modify and edit my Windows partition? | Are you using NTFS on your Windows partition? If so, thats the problem. All linux distributions have problems writing to NTFS.
I get around this by having a VFAT32 partition, that both Windows and Linux can write to. ... Alternatively you could write the files to a read/write CD or DVD. ... And then use that to copy files after you reboot from Linux to Windows. .... And you could use a USB stick, or external USB drive (formatted as VFAT32) as a place to use for file transfer. | |

| See the thing is ntfs writing support is a little iffy in linux at the moment, so that is the reason why you can't write to it from linux. You have a few options now:
1. The most obvious, burn the data to a cd/dvd from linux, then copy it over in windows from the cd/dvd.
2. Find a tool which can read the Linux partition from windows. See this post for some tools. Select the correct one based on the FS type that your suse partition uses.

| Ditto what everyone said about creating a fat32 partition, however, DO NOT cut and paste files from Linux to fat32 or the other way around as you can potentially loose your files in the twinkling of an eye. This happened to me once with disasterous results. COPY and paste files from Linux to Fat32 and vice versa. Then, after the files are transferred over to NTFS from fat32, you can safely delete them from Linux if you so choose. | |

| You have an option at the windows install, I think pressing either L or F2 (long time since I reinstalled windows) gave you the chance to format as FAT.
You can still create a fat32 partition if you want to do so using yast's partitioning tool. However, it won't convert the existing windows partition to fat, it will just resize a portion of the windows partition and create a new fat partition for you.

| Trust me, NTFS is good! Installing XP onto fat32 is like putting a Lexus chasis on a Edsel frame. 
This isn't hard once you get used to it. Got partition magic 8? Use it to resize Windows and make the small fat32 partition. Be SURE to defrag Windows and back up all need files before attempting any partitioning. Once the fat32 partition is icreated, get back and someone will show you how easy it is to mount it in Linux so you can copy those files over.  | |
