On my Opteron PC(ATI Xpress 200 + Uli M1573 chipset) with 320GB hard drive, winternals' one is stable. On my Pentium DC PC(Intel 865g + ICH5 chipset) with 640GB SATA hard drive, winternals' one always makes Win98SE crash when I delete files or use recycle bin. I tried paragon's one and lost my files in NTFS partition. Since then, I have not installed paragon's one.
