Hello, I just got my invitation through the tech beta nomination thread (thanks netryder) and attempted an installation. I have 2, 60gb sata hdds in a raid0 for a total of 120 gb. I used partition magic to move things around so that i had.. partition1(primary)- C: 90gb, used for storage partition2(extended)- D: 15gb, has XP running on it partition3(extended)- E: 15gb, new partition for vista Seemed to work fine, but a few minutes into the installation I got an error 80070570. From the bug reports people seem to think this is caused by a corrupt dvd. I exited, booted back into windows, reburned the dvd. At this point all hdd partitions, etc. seemed just fine, all were accessible, everything in disk management looks good. Then I booted from the dvd again to try to install. I decided to format the new partition (E just to have a clean start. The formatting failed. I deleted the partition & created a new partition. Tried to format it, no go. Rebooted back into XP. Now E: is inaccessible through windows explorer. When I try to format it, it looks like it's working, but when it's almost done it fails. So I open up disk management & wtf? I have hundreds of gigs of unpartitioned space & "unknown partitions", plus my E: now reads as 811 GB. (this is still on the 120gb raid0 array) The C & D drives seem totally unaffected, I am running XP off the D drive now with no problems. Can anyone point me in the right direction? or .... any direction? i've been messing around with it for a while now & am getting frustrated because nothing i've tried is able to change the partitions or format them. Attached is a pic of my disk management right now... Thanks in advance. EDIT: Here is another pic of partitionmagic's partitioninfo. Partitionmagic will no longer open(has an error reading the disk when I open it). However this utility would still work.
