Just because a process takes longer does not make it better. You can always find a longer way to accomplish a task. The size of your memory and really, the size of your buffer cache must be the problem. But you should use the raw device anyway.
That c201d4s0 does not look right to me either. But there are problems with the other devices names too. Something like /dev/rdsk/c0t6d0 is supposed to mean:
c0 (controller 0) the first scsi card configured in the system. It will have a chain of scsi devices and each device will have a scsi id. By convention, the controller itself will have an id of 7.
t6 (target 6) this is a device in the scsi chain. It will have a scsi id of 6. You seem to be saying that scsi id 4 got t6. That is a little odd.
d0 (disk 0) With ordinary disk mechs, d0 is all there ever is. But imagine 2 or 3 disks all sharing one scsi address. This is how you would tell them apart. This does get used in disk arrays.
All of this is a naming convention. You can call the disk /home/fred/stupid and it would still work. But don't do that.

Hi,
I have a windows emulator that I am wanting to try out, but my Windows 3.1 files are split up over 6 .DSK images, and I need to convert them to an .IMG that I can actually mount on my system (so that the emulator can see it).
Is there a way to do this?
thanks.

volfs(7FS) File Systems volfs(7FS)
NAME
volfs - Volume Management file system
DESCRIPTION
volfs is the Volume Management file system rooted at root_dir. The default location for root-dir is /vol, but this can be overridden using
the -d option of vold (see vold(1M)). This file system is maintained by the Volume Management daemon, vold, and will be considered to be
/vol for this description.
Media can be accessed in a logical manner (no association with a particular piece of hardware), or a physical manner (associated with a
particular piece of hardware).
Logical names for media are referred to through /vol/dsk and /vol/rdsk. /vol/dsk provides block access to random access devices. /vol/rdsk
provides character access to random access devices.
The /vol/rdsk and /vol/dsk directories are mirrors of one another. Any change to one is reflected in the other immediately. The dev_t for a
volume will be the same for both the block and character device.
The default permissions for /vol are mode=0555, owner=root, group=sys. The default permissions for /vol/dsk and /vol/rdsk are mode=01777,
owner=root, group=sys.
Physical references to media are obtained through /vol/dev. This hierarchy reflects the structure of the /dev name space. The default per-
missions for all directories in the /vol/dev hierarchy are mode=0555, owner=root, group=sys.
mkdir(2), rmdir(2), unlink(2) (rm), symlink(2) (ln -s), link(2) (ln), and rename(2) (mv) are supported, subject to normal file and direc-
tory permissions.
The following system calls are not supported in the /vol filesystem: creat(2), only when creating a file, and mknod(2).
If the media does not contain file systems that can be automatically mounted by rmmount(1M), users can gain access to the media through the
following /vol locations:
+-----------------------------------+------------------------------------+
| Location | State of Media |
+-----------------------------------+------------------------------------+
|/vol/dev/diskette0/unnamed_floppy | formatted unnamed floppy-block |
| | device access |
+-----------------------------------+------------------------------------+
|/vol/dev/rdiskette0/unnamed_floppy | formatted unnamed floppy-raw |
| | device access |
+-----------------------------------+------------------------------------+
|/vol/dev/diskette0/unlabeled | unlabeled floppy-block device |
| | access |
+-----------------------------------+------------------------------------+
|/vol/dev/rdiskette0/unlabeled | unlabeled floppy-raw device access |
+-----------------------------------+------------------------------------+
|/vol/dev/dsk/c0t6/unnamed_cdrom | CD-ROM-block device access |
+-----------------------------------+------------------------------------+
|/vol/dev/rdsk/c0t6/unnamed_cdrom | CD-ROM-raw device access |
+-----------------------------------+------------------------------------+
For more information on the location of CD-ROM and floppy media, see System Administration Guide: Basic Administration or rmmount(1M).
Partitions
Some media support the concept of a partition. If the label identifies partitions on the media, the name of the media becomes a directory
with partitions under it. Only valid partitions are represented. Partitions cannot be moved out of a directory.
For example, if disk volume 'foo' has three valid partitions, 0, 2, and 5, then:
/vol/dsk/foo/s0
/vol/dsk/foo/s2
/vol/dsk/foo/s5
for block access and
/vol/rdsk/foo/s0
/vol/rdsk/foo/s2
/vol/rdsk/foo/s5
for character access.
If a volume is relabeled to reflect different partitions, the name space changes to reflect the new partition layout.
A format program can check to see if there are others with the volume open and not allow the format to occur if it is. Volume Management,
however, does not explicitly prevent the rewriting of a label while others have the volume open. If a partition of a volume is open, and
the volume is relabeled to remove that partition, it will appear exactly as if the volume were missing. A notify event will be generated
and the user may cancel the operation with volcancel(1), if desired.
