I have a new HP Compaq laptop I have tried and failed to create unallocated space on the C drive (it has a C drive and a 10 Gig logical E drive with the operating system) using Partition Magic 8. I prepared with a defrag and ran Chkdsk /f. I disabled indexing and the antivirus (although of course because it is the C drive it only kicks in at reboot so they won't be working anyway) I continually get error message 1517 - missing file attribute This error is not in the manual but is on the website - that and other google searches indicate that you keep running chkdsk /f "3 or 4 or more " times Well I've done that 5 times the last 4 clean and I still get the 1517 error. What is the likelihood that if I buy DD10 that I will succeed in this situation where PM8 has failed? Any other suggestions welcome.
