AIT Drives Under USB? |
|
|
Has anyone been successful in using any flavor of AIT tape drive under USB,
mapped through IDE? I know Sony makes an IDE version of the drive, and it's
common these days to find cases that will map IDE/EIDE hard drives into USB
2.0. I assume those same casese could map an AIT IDE drive to the USB 2.0
bus, but I have no idea if the Sony tape drivers would work well under
Windows 2000/XP when using the tape drive through the USB 2.0 interface.

Do you mean the USB-to-IDE adapter boxes? If yes - they usually support
only a limited subset of SCSI, so I have doubts that the tape will work. You
can try though.

What would SCSI have to do with this if the tape device has a native IDE
interface?

Any IDE tape drive is not IDE, it is ATAPI, which means - SCSI commands
over the IDE cable.
Same is true for CD/DVD drives.
Same is true for USB storage, with the additional limitation of the USB
storage spec supporting a limited set of SCSI commands.

Pig ignorant wanking in your case.

Corse it is. What did you do to him to earn it's attention.
Pointless. Never showed any signs that it can read specs. |

1394 to AT Attachment - Tailgate,
specifies the protocol for passing ATA
and ATAPI commands over the 1394 bus.
I would expect the USB to IDE protocol to have a similar extension.
Unfortunately T13 does't seem to have been involved with that too.
USB + tailgate get's this in Google though:
http://www.cooldrives.com/dubayusb205o.html
"USB-MS-2BW is ideally suited for tailgate interface -applications for
removable-media drives CD-ROM, CD-R, CD-RW, DVD-ROM, DVD-RAM,
tape drive, and hard disk drive.
It allows IDE drives (Master and Slave) to be connected to USB 2.0 serial
bus in a plug-and-play fashion. Both ATA and ATAPI devices are supported
using the same firmware.

You would have to ask Sony whether the extension driver has an API interface to USB too. |

USBSTOR protocol supports only some subset of SCSI commands, not all of them.
The details are in the spec on www.usb.org

USBSTOR protocol supports only some subset of SCSI commands,
|
Which limits it to the use of what? Which SCSI classes are excluded?
And even if it did, what would that mean for ATA/ATAPI devices.
And even if it did, the bridge doesn't necessarily translate all of them
into ATA/ATAPI commands.
But nothing I could find about ATA/ATAPI, at least not without reading it
word for word. |

Don't remember. I only remember that the subset has some name, and is defined
in main SCSI specs. USBSTOR spec claims to only implement this subset.

There are six subclasses of the USB mass storage class. |
There is one that uses RBC instead of SBC, which Microsoft does not support.
Otherwise, SPC, SBC and MMC seem to be preferred.
Here as a good USB developer page: http://www.lvr.com/usb.htm .
=== USB Storage Classes ===
SubClass Code Command Block Specification Comment
01h Reduced Block Commands (RBC) T10 Project 1240-D
Typically, a Flash device uses RBC command blocks.
However, any Mass Storage device can use RBC command blocks.
02h SFF-8020i, MMC-2 (ATAPI)
Typically, a C/DVD device uses SFF-8020i or MMC-2 command blocks for its Mass Storage interface.
03h QIC-157 Typically, a tape device uses QIC-157 command blocks.
04h UFI Typically a floppy disk drive (FDD) device.
05h SFF-8070i Typically, a floppy disk drive (FDD) device uses
SFF-8070i command blocks. However, an FDD device can be in another subclass (for example, RBC)
and other types of storage devices can belong to the SFF-8070i subclass.
06h SCSI transparent command set.
07h - FFh Reserved for future use. |

Which presumably is the Host Program Interface, not necessarily what
travels over the USB cable.
Apparently USB leaves it to the OS on how to implement this interface.

Obviously.

Can't be. SCSI specs don't mention USB at all.
(Neither does USB spec mention SCSI at all for that matter).
| Quote: | USBSTOR spec claims to only implement this subset.
|
A subset of SCSI Primary Commands (SPC) presumably.
I don't think that that is necessarily a problem.
IINM, you need extension drivers for SCSI as well if
you want to use other than disk drives. |
