See TIP > Tape Drive Cleaning Strategies

  The TR-3 Tape Unit is a Magnetic-Influence sensitive-Device therefore the tape unit should be positioned as far as possible away from CD-ROMs, Hard-Disk Drives and/or Display Units.

Tape Capacity

The formatted capacity of a TR-3 tape will be about 1.6GB. Compressing raw data by a 2:1 ratio (compression ratios depends on data type) allows to store up to 3.2GB of raw data.

Preformatted Tapes  Some types of cartridges are available as formatted or unformatted. Where possible, IBM recommends pre-formatted tape minicartridges.
Unformatted Tapes  Unformatted TR-3 tape minicartridges must be formatted by the drive. Because the drive is formatting the equivalent of several hundred diskette disks, formatting can take up to six hours.
Flexible Formatting  The backup software supports Flexible Formatting standards and will autom. detect the length of the tape in a minicartridge. The tape is then formatted to its maximum allowable capacity.
Reformatting Tapes  Old tapes and tapes that are generating too many errors should be bulk-erased and then reformatted using the software format options. Erasing tapes with a commercial-grade bulk eraser is the best way to ensure that the tape is ready for reformatting. Commercial-grade bulk erasers are available at computer dealers.

Cleaning the Read/Write Head

  QIC-80 cleaning catridges are NOT compatible with QIC-3020 drives and will damage the read/write head.

After every 25 hours of operation (appr. 20 backup and or restore), clean the read/write head of the drive using any Dry-Process Cleaning Cartridge that meets the QIC-147 recognition specifications for QIC-3020 tape drives. Follow the instructions included with the cleaning cartridge.

Operating Temperature and Condensation

Let the drive and any tape minicartridge adjust to operating temperature (from 10° to 45°C or 50° to 113°F) before use. Do not operate the drive when condensation is present on the drive or tapes.

Help and Service Information
More Problem Solving Help  can be found on the Backup Software Diskette (README - file)
Problem    Solution
Backup Software cannot 1. Preformatted TR-3 tapes are formatted using 1Mbps or 2Mbps
   read a TR-3 tape.     controllers to take full advantage of the tape's capacity.
      If the tape is connected to a controller other than a
      1Mbps or 2Mbps controller, TR-3 tapes may not be readable.
  2. Try cleaning the read/write head
Floppy drive lights are on 1. Pin-one data-cable orientation correct ?
   and get an FDC failure  
Erratic, inconsistent performance 1. Data/Power Connection Cable reseat
   or tape drive is not seen 2. Software correct installed
      (Screen Saver installed ?)
  3. Reposition tape drive far away from Hard Drive
      CD-ROM and/or Monitor.
Drive works intermittently, or fails 1. Try using a new tape
   formats and has too many bad 2. Clean the read/write head
   blocks in the certify 3. Conflict with other Adapters
Formatting takes much longer than 1. Tape might be degrading. Use a newer tape.
