DOCUMENT:Q156363 10-AUG-2001 [winnt] TITLE :Tape and Drive Compatibility for QIC 117 S PRODUCT :Microsoft Windows NT PROD/VER:WinNT:4.0 OPER/SYS: KEYWORDS:kbhw kbHardware ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Workstation version 4.0 - Microsoft Windows NT Server version 4.0 ------------------------------------------------------------------------------- SUMMARY ======= Compatibilty and tape capacity for QIC 117 standard tape backups depend on the floppy disk drive controller, tape format, and the tape backup unit. MORE INFORMATION ================ The controller requirements for floppy disk drive-based backups are as follows: QIC117 Standard Supported Tape Formats =============== ====================== QIC-40 Read/write QIC-40 tapes QIC-80 Read QIC-40 tapes Read/write QIC/80 tapes Includes WIDE and TR-1 formatted tapes QIC-3010 Read QIC-40/80 tapes Read/write QIC-3010 tapes Includes WIDE and TR-2 formatted tapes if the drive will accept these QIC-3020 Read QIC-40/80 tapes and QIC-3010 tapes Read/write QIC-3020 tapes Includes WIDE and TR-3 tapes To determine the computer's floppy disk drive controller type through the Windows NT registry, please see the following article in the Microsoft Knowledge Base: ARTICLE-ID: Q156362 TITLE : Floppy Controller Requirements for QIC-117 QIC drives will not read tapes formatted with a later QIC Drive series format. For example, QIC-3010 drives will not read QIC-3020-formatted tapes. QIC-40/80 drives will not read QIC-3010 or QIC-3020-formatted tapes. The drive's functionality and capacity are limited to the lowest common denominator of floppy disk drive controller speed, tape backup unit, or the tape format itself. A QIC-3020 that requires a 1 Mbps controller for full functionality essentially becomes a QIC-3010 series drive when placed on a 500 Kbps controller (and shares the same behavior and limitations as a 3010 Series drive). Compatibility and limitations are summarized in the chart below: Tape Format QIC117 Standard 40 80 3010 3020 =============== =========================== 40 RW x x x 80 R RW x x 3010 R R RW x 3020 R R R RW x = unsupported configuration Additional query words: tape travan wide qic117 backup ====================================================================== Keywords : kbhw kbHardware Technology : kbWinNTsearch kbWinNTWsearch kbWinNTW400 kbWinNTW400search kbWinNT400search kbWinNTSsearch kbWinNTS400search kbWinNTS400 Version : WinNT:4.0 ============================================================================= THE INFORMATION PROVIDED IN THE MICROSOFT KNOWLEDGE BASE IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND.
