I have two HDDs>> hd0 is internal , hd1 is external.

I installed Ubuntu 9.04 in the external hdd as follows:
"\home" ext3-partition in (hd1,2)
"\root" ext3-partition in (hd1,3)
"swap" partition in (hd1,4)

During installation, I changed the bootloader setting. (I intended Ubuntu 9.04 to boot from the external hard disk itself.) I set the (hd1,0) NTFS partition for installing the boot-loader. [I thought the bootloader will be installed in that NTFS partition & its data will remain intact.

Now (hd1,0) is a partition of 800GB(!!!) & it contains ~560GB of my data which I'm unable to access from Windows/ newly installed Ubuntu 9.04/ Ubuntu 8.10 live-disk...Windows is unable to read the data (as expected :D); Windows wants to format the disk before using!!!

Unexpectedly, Ubuntu doesn't even show the 800-GB space in "Places/Computer" although it shows the partition as of "Unknown file system" in "GParted" (partition editor).

I need the data (~560GB)... pl help...

It looks like something wicked happened to that NTFS partition. My move would be to pay for Stellar Phoenix or equivalent data rescue/forensic tool. In that case, you will need that ~560gb of free space from some other drive, since those tools are for copying data - not repairing broken filesystems.

(possibly off-topic) Linux's NTFS resize included in some older Ubuntu version installers is an effective way to trash Windows versions beyond XP. – Jouni Kivilahti Feb 13 '13 at 9:55
I wonder Ubuntu can't read the file system where it has installed its own bootloader!! – user130682 Feb 13 '13 at 14:10
Can't say, what happened. A bug somewhere? I'm not endorsing software piracy, piratebay versions are illegal. But I endorse you to try out that Stellar Phoenix, I tried it years ago. It really saved my day. – Jouni Kivilahti Feb 14 '13 at 0:27
Stellar Phoenix worked brilliantly!! – user130682 Feb 16 '13 at 7:36
