Windows will not detect DAT drive |
|
|
Seagate/Certance STD 2401LW DAT drive connected through an Adaptec 2940UW.
The SCSI controller can see the drive ok but Windows (2003) simply refuses
to recognise that there is a tape drive attached. No tape drives visible,
nothing in other devices.
Any ideas?
Cheers,
Nick |

Windows does include a driver for this device 4mmDat.sys, just that it
doesn't seem to work.

Unless Windoze includes a driver for that device, why would it see it?
I would expect your backup software to see the device.

Interesting, I had an HP1537A running on an Adaptec 29160P on an NT4 server
no problems for the past four years or so but gone to a new home now.
So question is how do we establish if this is a hardware incompatibility or
a Windows problem? By the way I have tried using Win2K and had the same
problem.

Thanks Eric,
Just tried that and it sees the aic78xx adapter but nothing detected on the
bus. It reports the following info:
Data buffer Alignment: Byte
Max Transfer Size: 64Kb
Residual Byte Count: Supported
Asyncronour Event Notification: Not supported
SCSI tagged queueing: Supported
Any clues in there?

It does not use any Windows class drivers and scan the SCSI bus. You can
verify tape/disk media if it sees the drive.

Yes, but why does NT++ need specific 'device' drivers when 9x does not?

Isn't that how it works on Win9x? So why should it be different for NT++. |

It uses the Win 2K scsi port driver. It does not require building a boot disk. |

My DDS drive runs under Bill Gates best OS so far, OS/2, so my comments
reflect this experience.
I run XP Home workstations and I was indeed able to get a SCSI scanner
working just by putting a SCSI adapter in the PCI bus and plugging the
scanner to it.
I can see the OS/2 heritage in the XP command language, and Folkert's
comments suggest that NT was even closer to OS/2. |

Windows NT and family has a defined tape API, which allows tape drive
manufacturers to implement a driver. Once the driver is in place then any
backup software that is written for the API can make use of that tape
device.
Windows 9x does not have such API. Backup software has to directly address
the tape hardware and therefor support all specifics of each 'supported'
device on it's own.

Sounds like ASPI for Tapes. So no specific need for a driver.

That's mad. Unless the API has to be included in the driver,
i.e. the driver *is* the API. But then, that's mad too.

Which it can't do without using the W9x driver.

No, you're missing the point that NT has a layered structure. The lowest
layer is the SCSI (mini)port driver which directly interacts with the SCSI
HBA hardware. It fiddles with registers and bits on the SCSI card chipset.
It exposes a standard API through which the next layer can send SCSI
commands. This is comparable to ASPI.
The next layer is the tape driver (Disk and CD/DVD drivers are on this same
level). It uses the SCSI (mini)port API to send SCSI commands. On the other
side of this driver it exposes the Tape API which consists of higher level
commands. As an example there's a standard API function to partition tapes.
If a backup application wants to use partitions, it simply calls the tape
driver and specifies the number and size of the desired partitions. The tape
driver then sends one or more SCSI commands specific to the tape drive for
which the driver is written. Those specifics are entirely transparant to the
backup application. In fact, the tape drive could have any weird interface
(floppy, ide, fibre, QIC-02, you name it), and as long as there's a tape
driver for it, the backup application can use it.

No, ASPI/SPTI support sending SCSI commands to SCSI devices. It's the
application on top that needs to implement the specifics for each and every
tape drive it claims to support. That's why you won't find additional
drivers for the backup application that came bundled with Win9x. It's a
monolithic piece of software that can't be persuaded to talk to anything but
a fixed list of supported drives.
| Quote: |

|
Commercial backup software vendors defined their own layers, wrote their own
tape specifc drivers on Win9x, which then exposed their own proprietary tape
API to their own backup application. A Win9x driver for ArcServe is of no
use to BackupExec.
