But to my amusment when i first booted back in Winxp the 100Gb partition is although shown in My Computer but double clicking it says : "E:\ not accessible parameter not correct"!!!! or sometimes if i skip the disk scan at boot up it says ""e:\not accessible the file or directory is either corrupted or unreadable" *File system is NTFS *The disk is shown as logical in Disk Managment and all recovery tools i tried!!!!:giddy: Please help me get it working back on track as i got loads of my data on it!!!!
