#178780 - HP Ultrium Responding to: ???'s previous message |
You want me to give an example of normal behaviour, i.e. a tape drive that does not show up as a file system? Is that really meaningful? Well, the HP Ultrium doesn't show up as a file system unless the one-button recovery button is pressed.
But it wasn't Microsoft that made the tape drive bootable. When a tape drive connects using SCSI, USB or similar, the device manufacturer have a choice what they want their device to enumerate as. HP did make their tape drive bootable for the simple reason that a huge number of their users have been unable to restore their backups because they have lost their backup software or some OS or driver disks. Having a HP tape streamer that can switch to be bootable on the press of a button means the connected server can perform a basic system restore without need for OS disks. And the tape streamer does only show up as a CD-ROM so a virus on the machine can't perform any writes. The first tape drives that had some form of "direct access" have been with us for 30 years or maybe more. More than 10 years ago, I could do direct access using Seagate DTA, for their Jumbo tape drives. And before Win NT you had the old DATMAN application. None of the above had anything with Microsoft to do. But sorry - while I have seen a number of drives that could themselves (no Microsoft involved) look like a disk drive, I have never once seen any tape drive that Microsoft makes into a disk drive, without the drive already enumerating as a CD-ROM or HDD. There exists a number of tape file systems - file systems optimized for use on tape drives. Very good to use for a huge data center with multi-tiered data storage - seldom used files gets retrieved from a band robot system. But that isn't directly the normal use of Windows. People who need HSM (Hierarchical Storage Management) or the cooler ILM (Information Lifecycle Management) don't magically get it by connecting a tape drive to a Windows machine. Can you post any example of any tape drive that does not enumerate as a disk but gets automatically presented as a file system in Windows? |
