PIII 1GHz
2 IBM (21GB ATA66 & 75GB ATA100)
Supermicro P3SCD 820 Camino
Promise FasTrak TX2
512MB PC133 CAS2


i have it setup at the moment with 4 masters, 2 cdrom, 2 Hard Dsiks
0+1 stripe.... on my boot drive i have 3 os`s duel boot and a serveron NTFS filesys, SO 4 PARTITIONS that`s the 75GB IBM. The other drive is CLEAN FORMAT NTFS. What i don`t get is how do i set up mode stripe 0, when i do this by using promise bootup utility it will not boot.

can some1 explain this to me please or gimme some hints on setup for FASTEST DRIVE SPEED !!! which i know is mode 0

you have 2 drives, a 21GB and a 75 GB.

and you want RAID 0.

the minimum requirements for RAID 0 is 2 HDDs, which you have met.

BUT since you have 2 different drives, with RAID 0, you can only get up to 2x the speed of the slowest drive, and 2x the capacity of the smallest drive. if your drives were identical, that's the typical setup for RAID, you would get 2x the capacity and speed of a drive, either one.

you already have data on both drives, well data in one, and another which is formatted. if you do create a RAID array, you will get a single array of 42 GB running at ata66. any previous data NOT BACKed UP would be lost upon creating the array.

I would advice you to get another HDD as to not waste the some 50 GB of the 75 GB HDD.

if you have done what i think you have done, you are really in trouble.

by array, I mean a RAID implementation, which is essentially seen as one drive by an operating system. a raid array has to have at least one drive. a single drive array would not benefit from RAID, but does allow a single drive to be used via a raid controller.

upon creation of the array, you have to start working to "format" and prepare the new array for use. Thus, when you have created the array via the setup utility (accessed via the instructions on the manual), you have to fdisk (any file allocation format, FAT or NTFS, or whatever) and format all over again, since you basically "created" a new drive which represents the array.

once you have prepared the array, you need to install the OS as per the controller's manual's instructions. for linux or win2k, you have to have the drivers for the raid controller handy as you need them to even install the operatings system properly. for win9x, generally, the controller would be run using a generic driver (MS-DOS compatibility) after which you have to install the proper drivers for the computer to function normally. DOS compatibility leads to performance decreases.

if you have a backup copy of any operating system, migration is tricky because sometimes you won't be able to boot. This is especially true with win2k (winNT in general) and linux. You have to read and follow the manufacturer's instructions PRECISELY. and even then, it may still not work.

in general, i recommend a reinstall of the operating system(s) if migrating to RAID or even another storage standard (scsi <-> ide)
