Press the Eject button on the front of the tape drive Sometimes it is necessary to use the Eject button instead of software to unload a tape because software can lose LTO 5 Tape Drive User s Guide LTO 5 Tape Drive User s Guide Chapter 6 Troubleshooting Guide Problems with cartridges communication with the product or a rogue application can prevent the software from unloading the tape Caution This can take several minutes in many cases Ensure that drive activity has stopped before continuing on waiting 10 minutes is a good rule of thumb It is important that you allow sufficient time for the drive to complete rewinding the cartridge If you interrupt it you may damage the media or the tape drive 4 Power down the drive 5 Disconnect the data cable 6 After at least 15 seconds power the drive back up and wait till the drive is idle ready Caution Use care when disconnecting data cables to ensure that connectors are not reversed pins are not bent and so on Caution Powering up with a cartridge in the drive can take several minutes It is important that you allow sufficient time for the drive to complete rewinding the cartridge If you interrupt it you may damage the media or the tape drive 7 Ensure that drive activity has stopped waiting 10 minutes after power up is a good rule of thumb Push the Eject button This step attempts to overcome unload issues due to the drive
3. WORM Data Cartridges The LTO 5 tape drive includes support for both re writable and Write Once Read Many WORM data cartridges WORM cartridges provide an enhanced level of data security against accidental or malicious alteration of data on the tape cartridge The WORM data cartridge can be appended to maximize the full capacity of the tape cartridge but the user will be unable to erase or overwrite data on the cartridge Any attempt to modify a WORM cartridge to enable writing over existing data will result in the media becoming permanently write protected It should still be readable in a WORM drive depending upon the severity of the tampering but no further appended backups will be possible WORM data cartridges are clearly identified by their distinctive two tone cartridge color They can only be used with Ultrium tape drives that support the WORM feature LTO 5 Tape Drives and Partitioning The LTO 5 tape drive supports two tape partitions when used with Ultrium 3TB R W cartridges Tape partitioning is not supported with WORM cartridges or with earlier generations of cartridge See your backup application s documentation for more information about partitioning media LTO 5 Tape Drives and Encryption The LTO 5 tape drive includes hardware capable of performing data encryption at full speed while writing data and decrypting when reading Encryption is the process of changing data into a form that cannot be read until it i

Data Compression Considerations 42 The same amount of information can be stored on a smaller length of tape More data can be stored on a given length of tape Performance can more closely parallel to that of high transfer rate computers More information can be transferred in the same time interval In an effective data compression method several factors are important The amount of compression which is measured by the compression ratio This ratio compares the amount of uncompressed data to the amount of compressed data It is obtained by dividing the size of the uncompressed data by the size of the compressed data The speed with which data is compressed and decompressed relative to the host transfer rate The types of data to be compressed The data integrity of the compressed data The amount of compression possible in a data stream depends on factors such as Data pattern Compression algorithm Pattern repetition length Pattern repetition frequency Object size block of information to be compressed Starting pattern chosen The transfer rate depends on factors such as Compression ratio Drive buffer size Host computer input output I O speed Effective disc speeds of the host computer Record lengths that the host computer transmits LTO 5 Tape Drive User s Guide Intelligent Data Compression LTO 5 Tape Drive User s Guide Chapter 4 Theory Data Compression Data compression algori
