I had Windows XP installed, with 4 partitions one of them was FAT32, others NTFS. Some Windows files got corrupted and the PC refused to start, so had to reinstall XP, later I found out that the FAT32 partition didn't show any contents, first I thought they got hidden, so took the necessary steps, but no data was shown. Still the properties said 28 out of the 29GB were occupied. I did the Disk Cleanup, it showed 28GB of some weird data, maybe CHKDSK.. after cleaning up the disk, it was all gone, properties showed full partition to be empty! Is there any chance to get the data back. There was no problem before I had to reinstall XP.
