Hello
i am looking for a bit of help please
i got a hp comapq nc6320 laptop and last night i wnated to reinstall my XP, i didnt like the way it was originaly done so i wanted to change it
i started of lounching partition magic in dos to crate aditional partitions because the laptop had only on c: with 75gm and one hp recovary of 5gb
so i deleted them all refoarmated and created a primary disk av 15gb and the rest a logical one
i started the xp install and after it finished loading its files ii recived a error that no hdd drives were detected
i the ran HDAT2 and saw the my hDD had DCO status frozen( protected by BIOS) after further research i came to to this document
"Q: What are HPA and DCO areas?
A: HPA is an acronym for Host Protected Area. A HPA is a portion of sectors at
the end of the hard drive that can not be addressed by the user. Normally this
area is used to store hard drive diagnostic or recovery type software, but any
type of data may reside in this area. DCO is an acronym for Device Configuration
Overlay. Similar to a HPA, a DCO represents a portion at the end of the hard
drive that is not user addressable. Both these areas are NOT overwritten when
a windows format, secure/enhanced erase, or any other overwrite method is
performed. In order for these areas to be erased they have to be first removed,
and only then can the entire drive be erased (see the following question).
***Note: In our testing some drives overwrite the HPA when a secure erase is
performed, but most drives do not erase this area when a secure erase is
performed. CMRR contends that HPA erasure is not mandatory because user data is
not stored there; however HDDerase offers erasure of both areas for maximum erase
security."
so i tryed using HDDerase but this program coundnt detect any HDD
al the other diagnostic and partition programs i used can see the DRIVE
so any1 knows how to fix this little problem?
thank you
