Windows 2003 Server SCSI device access |
|
|
Hi,
I'm having problems accessing a SCSI device under Windows 2003 Server as a
non administrator user.
I'm using:
CreateFile( \\Scsi0:, GENERIC_READ | GENERIC_WRITE, FILE_SHARE_READ |
FILE_SHARE_WRITE, 0, OPEN_EXISTING, 0, 0 )
This works OK on NT, 2000, XP and also on 2003 for a user who is a member of
the Administrators group, however it fails for Backup Operators.
Any ideas how I can get this to work for Backup Operators users? |

If it is a disk you can just open \\.\physicaldrive#. Disks permissions are
limited to Administators either way.
If you disable the disk device, you can access it through SPTI using SCSI#:,
however that is a bug.

This is a tape or robotic device I'm trying to access, however I want to
construct my own SCSI commands so don't want to use the \\.\Tape0 interface.
There was a typo in my original post, I meant to say \\.\Scsi0 |

There's no reason why you can not send your own commands to \\.\Tape0:
Read about DeviceIoControl() and IOCTL_SCSI_PASS_THROUGH_DIRECT
Check the SPTI example in your Windows DDK, it shows how to construct the
command.
