IBM 7205-550 160GB

The following is a chart that shows the interchange using the IBM 7205-550 tape drive.

Notes:

z The 7205 Model 550 has full backward read-only compatibility with the currently available IBM 7205 Model 440

(DLT8000) tape drives.

z The 7205 Model 550 is read-only compatible with older 7205 Model 311 (DLT7000), 7205 Model 305 & 306

(DLT4000), and DLT3000 tape drive formats (DLT Tape IV).

z The 7205 Model 550 is also read and write compatible with the SDLT220 tape format (SDLT Tape 1) at the native

transfer rate of the SDLT220 tape drive (11 MB/sec).

z Non-SDLT drives will eject a cartridge written in SDLT320 format.

Tape Drive Cleaning Frequency

Details the recommended tape cleaning frequencies* and proper cleaning cartridge to use for the 1/4", 4mm, VXA, LTO,

8mm, and DLT tape drives.

Other information you should be aware of:

z Clean the tape drive at the recommended times and with the recommended IBM cleaning cartridge. Over cleaning

may cause premature head wear out, do not over clean the tape drive.

z Whenever a tape drive reports an I/O error the drive should be cleaned prior to retrying the tape operation.

z The 4mm, 8mm, and VXA cleaning cartridges move the cleaning media from the supply spool to the take up spool in

the cartridge during the cleaning operation. When cleaning is complete the area of the cleaning media used in cleaning

is wound onto the take up spool, unlike data cartridges that rewind all the media back onto the supply spool.

To determine if a 4mm, 8mm, or VXA cleaning cartridges is used up users should not only check the number of

remaining cleanings as marked on the cartridge but also observe the remaining media on the supply spool.

To do this:

The user should hold the cleaning cartridge as if they were going to insert the cleaning cartridge into the drive. If all,

or most, of the media is on the right hand, take up spool, and very little media is still on the supply spool, the cleaning

cartridge is used up and will not clean the tape drive.

z If a 4mm, LTO, 8mm, or VXA cleaning cartridge has been used its maximum number of cleanings and the cartridge is

inserted into the tape drive the cleaning LED will not go off if it was previously on and if the cleaning LED was off

prior to the cleaning cartridges insertion the cleaning LED will be turned on to signify the cleaning was not done and

the cleaning cartridge has exceeded its maximum number of uses.

z There are times when it will be necessary to use the recommended cleaning process several times in a row to clean the

drive:

{ Tape drives that have not been cleaned according to the recommended schedule.

{ Tape drives where unsupported media or cleaning cartridges were used.

{ Tape drives reporting repeated I/O errors.

{ Tape drives operating in dirty/dust environments.

If repeated cleanin

s and new media do not eliminate the I/O errors it ma

be necessar

to replace the tape drive.
