hi I am just about to format and reinstall everything because i have changed things around in my computer so i need some help with 2 things i am not sure about. I now have 3 H/D's partitioned into 2 drives, as below. these H/D's are all Online/BASIC/ NTFS. Q:1 Would i be better to convert them to Dynamic Disc's or not. also if so would i lose all my data on my store drives. what are the benefits if any. My H/D Setup. Disc-0 Master = HD-1 = 120Gb Samsung SP120 3N, partition-1 = (CWinXP Pro, partition-2 = (DDrive-1 Store-1 Disc-1 Slave = HD-2 = 120Gb WD1200BB-00DWA0, partition-1 = (EDrive-2 Store-1, partition-2 = (FDrive-2 Store-2 Disc-2 Slave = HD-3 = 200Gb MAXTOR-6B200P0, partition-1 = (GDrive-3 Store-1, partition-2 = (HDrive-3 Store-2 Drive= (I= CD-Rom = NEC-DVD-RW-DL Next part When my computer boots there is a message on the screen which says, "see below". When i pres TAB and go into the User Window nothing seems to happen and WinXP just boots as normal. My motherboard is Jetway V600DAP with SATA/RAID ect, message on boot screen Scan Devices Press <TAB> Key into User Window. Serial-CH0 Master: No Device Serial-CH1 Master: No Device Q-2 I am not sure whats this for, am i missing something or is my motherboard just looking for SCSI H/Drives. There is a VIA RAID tool loaded when i install my motherboard drivers, but when i use it it says, (No stand-alone disk and No usable disk array attached, please check if any disk array is broken.) My drives are SATA Serial ATA Drives, if i am correct? hope so. hope someone can help.
