    I have a DC dev unit, and it didn't come with a hard drive. I just aquired a 4gb SCSI hard drive. I can't get it to work with my dev box/GD Workshop. How must I properly set this up for use with my dev box (should I format it as a FAT, FAT32, NTFS disk, what jumper should the drive be set to, etc)?

    thank you

    Here you go:

    The Katana development box is always shipped with it’s emulation drive formatted with a single 2 GB FAT16 partition so that it is compatible with Windows 95, OSR2 and NTFS operating systems. However, the emulation drive fitted is actually 4 GB capacity.

    If you want to reformat the internal drive or add an external drive for extra capacity, the emulation drive must be formatted with a cluster size of 32K or above.

    Caution: If the emulation drive is formatted with a cluster size smaller than 32K, the emulator will not emulate.

    Note: If you are running GD Workshop on Windows 95 (non-OSR2), you can only format the emulation drive using FAT16 with a maximum 2 GB partition size, regardless of the size of the emulation drive.

    To format the emulation drive with NTFS using Windows NT operating system:

    1 From the Windows NT Start menu select Programs > Administrative Tools > Disk Administrator.

    2 In Disk Administrator select the emulation drive you want to format.
    3 On the Partition menu select Delete and answer Yes to delete the current partition.
    4 On the Partition menu select Create.
    5 Enter the size of the new partition you want to create, click OK, and answer Yes to create a new partition.
    6 On the Partition menu select Commit Changes Now and exit Disk Administrator.
    7 On the Start menu select Programs > Command Prompt.
    8 At the Command Prompt use the following command line:

    format [drive letter]: /fs:ntfs /a:32k

    where:

    /fs is the switch to set the file system
    /a is the switch to set the cluster size
    32K = cluster size.

    9 Press Enter to start formatting.

    To format the emulation drive with a FAT32 file system using Windows 95 OSR2 operating system:

    1 In GD Workshop select Hardware from the Configuration menu.

    2 Uncheck the Drive Removable option.
    3 In Windows set the emulation drive to Non-removable and Int13:

    right-click My Computer,
    select Properties,
    select Device Manager,
    under Disk Drives double click the emulation drive you want to format,
    select Settings and uncheck Removable and check Int13.

    4 Reboot the development computer.
    5 In a DOS box use FDISK or AFDISK to create a partition on the emulation drive of the required size. Note that if you have checked Int13 FDISK will not see the drive.
    6 Reboot the development computer.
    7 In a DOS box use the following command line to format the emulation drive:

    format [drive letter]: /z:64

    where:

    /z is an undocumented switch to set the number of sectors per cluster
    64 sectors of 512 bytes = 32K cluster size.

    8 When formatting is complete, reset the drive properties in Windows to Removable, see step 3 above.
    9 Reboot the development computer.

    10 Start GD Workshop and reset the drive properties to Removable, see steps 1 and 2 above.

    bigsexyolli,

    how would i format the drive in windows XP? Would I connect the drive to my PC directly or format it while it's connected to my dev unit?

  5. You should be able to do it whilst it's fitted in the Dev Kit.

    ...Just use XP as if it were NT

    oldengineer,

    XP doesnt even see the drive in my dev box (first, i don't even see an option in XP called disk administrator). When I open GD Workshop, it says "The following drives report themselves as removeable but are uncrecognized G:Incorrect function. After a few more boxes, it goes to Configure Drive Letters but I can't go into the main program. In the SCSI Bus Configuration, I see the Katana DA, and GD-M, but under the GD-M, it lists a hard drive with SCSI ID #0 but there is a yellow exclaimation mark on it.

    By the way, how should i set up the DC dev for this formattting/emulation task (I mean, how should i set the dip switches and slide switch)?

    If that doesn't work, try to connect it to your pc directly. I cant say if this would work. I have never encountered this problem, because I didn't connect my devbox because I dont have the right cables and scsi stuff yet. Come to think of it, do you have all the SCSi terminators connected to the devbox? Maybe that is why it cant recongise it correctly. If it all fails, the drive might be broken.

    I just looked into the devbox and couldn't see any jumpers, I suppose scsi hds don't have any (Please correct me if I'm wrong!)

    Here is a setup-pic, if it helps...


    Addition:

    I think the dip switches and slide switches sould stay normal, couldn't find anything in the docs about that. For the rright settings, see the other attacements

    hope it helps...

    I don't have any SCSI terminators...maybe that's why things arent working too good.
     

  9. In XP right click on 'My Computer', then select 'Manage', this will bring up a disc management screen.

    ...From this you should be able to select the drive and format it, providing you have fitted a SCSI terminator to the Dev Kit.
     

  10. Oh, yes, you won't get anywhere until you get the SCSI circuit terminated.

    So I guess the problem is solved! :)

    We'll see, once I get the SCSI terminators I need. Will report when I do.
    If I have a 9gb hard drive in this dev box, can I only use 2gb of it (like the above documentation implies)?

    if you foramt it as a fat16 drive, it will not be bigger thatn 2 gb, since fat16 dosn't allow sizes bigger than 2 gb. If possibly format it as ntfs, that way you can use all the capacity

    Well, i have connected the scsi terminators to the dev box, and my computer STILL will not format or recognize my drive. I have tried this with 2 dev boxes and 3 different hard drives.
    I am at a total loss...

    Well,you can send me one of the harddrives and i can check it out on my box.
    I had a similar probem back when i first formatted the Disk from Fat16 to NTFS , but i cannot really remember what i did to make i work...It was almost like a year ago...

    Vitamen,

    Thanx. If you could, maybe format it and use it in your own box so I know it works before you ship to me. Or if you have a spare hard drive, I can buy it off you provided that you format it for use in the dev box.

    By the way, does it matter what SCSI control card I have? I have an Adaptec 2940.

    please email me at eastbayarb@gmail.com

    The adaptec 2940 is the card Sega recommended.So you do not have problems on that front...

    If you decide to send me the harddrive drop me a mail so we can talk the details...I'll set it up in my box so i can be sure that it works before i send it back...

    Cheers

    Good stuff...nice to hear it's working...

    Can you please check out the transfer speeds between the host machine and the DevBox harddisk?Mine seem to be pretty low for an ultrascsi setup (20mb/s).I get around 2.5 mb/s :(

    Here is a helpful utility:
