I have the same problem here also benjamin1254 & I bought the DVD from ebay also,the DVD running in the live mode very good but I like to install it on the hard drive ,I have 3 hard drives in my system one of them is 8 GB I formated it useing partation magic to 7.50 GB ext3 & the rest for the swap & every time I start installing using knx2hd or knoppix-installer it say it need to format again because knoppix can't find suitable partations for it so I start to foloow it's instructions but when i choose the hard drive it say busy so I thought this is because the hard drive is already mounted so I went to check it I didn't find unmount & just found mount ,I tried to change the premission for reading & writting then tried again & now it's not saying busy it's saying read only,in fact Iam almost give up from all that & I wish I can find anyone have a solution for this.
