I had 3 HDDs installed. My main one was split into 2 partitions. One partition had win xp and the other had all my data i wanted to keep because i was gonna format. The other 2 hdds also had data i wanted to keep. I started to install windows 2k from a disk that i know works. After it formatted my windows partition it copied files to it then reboot. And now its usually supposed to start installing windows and everything, but i just got a black screen. After i decided it wouldnt work, i rebooted and same thing. I started the windows CD again and the list of HDDs showed that my main drive showed like 4 partitions now and 2 were unformatted and 2 had no label. (not exactly sure what it said). I got another HDD and installed win2k on it from the same disk and it worked, THat was the only HDD installed at the time. THen i put in my main hdd and it was read as like 127 and the only folder was WINNT. I think this same partition was auctually 131GB in my windows xp instalation. I Used hiren's boot CD 8 and parition manager sees my main hdd as one damaged partition. Now i ran A different partition manager and it sees this HDD as having 4 partitions. One is Free (File system) and 80.4GB. The other is Free and 23.6GB. ANother is Invalid and is 812GB. And the last is 259GB. THe two invalid patitons have no label and are not active and are hidden. The other two have blank labels, are not hidden, and are not active either. However, on the top where it shows a graph of the partitions. It says the Drive is 232GB (Which it is) and the different sections are a size proportinate to the flase reading it gives. I really would like to save my data. Once i can gain access to it I will burn it all off. I was thinking to install winxp on the hdd that i installed win2k on or putting it in my bro's pc with winxp already on it. Please Help....
