If a SCSI interface is detected, an additional menu option will be enabled under the File menu of the Main window - Replay SCSI disk. All available SCSI chains and devices will be checked for the presence of a SAM
or DFD SCSI disk. If any are found, the information
is read and displayed. As many streams as required can be selected for replay, and in any combination. (using standard Windows operations of selecting rows whilst holding the control key). When OK is clicked a new replay group will be created, and replay can be controlled in exactly the same way as for standard
file replay.
The selection process may be performed as many times as desired, to create any number of replay groups.
To transfer data from SCSI disk into the file system, select recording for the streams replayed from SCSI. All settings for stream recording are used (i.e. file size and location).
Note : For maximum transfer rate, the replayed streams should not be displayed. This allows a higher replay rate to be achieved.
The SCSI disks can be ‘reset’, allowing them to be used again in SAM or 6TD units as blank disks. Select the ‘Reset SCSI disk’ menu option for this. Note that disks which are detected as having DOS formatting will not be included in the reset operation.
Windows: Scream will first attempt to use an ASPI interface layer. If this is not possible, scream will then attempt to open the disk device using Windows NT semantics (and other variants based on NT, like Windows 2000 and XP). In order for this to succeed, Scream must be run with administrative privileges. The disk should appear in the windows "Device Manager" in order for scream to be able to access it. This also means that all disk types (eg. Firewire or USB disks) can be included, not just SCSI disks.
Linux: In order for Scream to directly access disk devices, it must be run with root privileges. If this is not possible, the permissions of the disk device can be changed to allow non-root users access to the disk (using chmod or chown).
Up to 100 disks connected to the system at once are supported, although the
operating system or hardware may not support this number. Using command line
parameters, files which contain disk images can be mapped into disk numbers. For
example, if file "image.bin" contains an image of a SAM disk, the
command line parameter "/disk10=image.bin" maps this file to be used
as if it was disk device number 10. The "/diskX=" parameter can be repeated
as many times as necessary.
On linux, a disk image can be created using the 'dd' command. Please see linux
man pages for more information on using 'dd'.
