CLEANING A DRIVE
Overview Wheneveratapeisloadedorunloaded,theread/writeheads
arephysicallycleanedbyabrushlocatedwithinthedrive.However,after
readingandwritingalargeamountofdata(theexactamountvariesby
drivetypeandgeneration)orifreadorwriteerrorsoccur,thedrive
requeststobecleanedwithacleaningcartridge.Therequestismadeby
sendingaTapeAlertmessagetothehost,anddisplayingaContheSCD
Thenotificationisalsopostedtothelibrary’sDriveDetailsscreen

Usingdriveswithdirtyheadscanreducedriveperformance,decrease
usabletapecapacity,andresultinread/writefailureswhicheventually
interruptdatastorage.
IfyouhaveAutoDriveCleanenabledandthedriveisinapartitionwith
anassociatedcleaningpartition,thesecleaningsareperformed
automatically.SeeCreatingaCleaningPartitiononpage165for

Itmayalsobepossibletoconfigurethehostsoftwaretoautomatically
cleanthedrives,withacleaningtapestoredinthepartition,whenthe
softwareisnotifiedthatdrivecleaningisnecessary.
Ifnoautomaticcleaningprocessisconfigured,youmustmanuallyclean
thedrive.Ifyouignoreacleaningrequestfortoolong,thelibrary
generatesawarningsystemmessage.
