NTFS Hard Disk Unaccessable

History: I have 2 hard disks 1x40GB (disk0) and 1x160GB (Disk1) with Windows XP installed on 1st partition on drive0. in order to access the full data on drive1 I have used the intel IAA utility. This was used after disk was partitioned and therefore I used a dynamic XP partiton to see the whole disk1 as a single disk combining the 134GB partition and the remaining 26GB partition.

Question: I was installing Win98Se on disk0 and seem to have disabled the disk1 and am now unable to read this disk with ALL my data on.

Help on this would be VERY appreciated.
