USBDEVICEFAULT. ThisindicatesthattheXT2640hasdetectedthedeviceasbeingattachedbutthedevicefailedto
enumerateproperly.Thismayindicatethatthedevicedrawsmorethan500mAofpowerorthatthe
driveisnotcompatiblewiththeUSB2.0specification.Thedriveshouldberemovedandafterwaiting
afewsecondsitshouldbereinserted,ifthemessagereturnsthenthedriveisnotcompatiblewith
theXT2640(thiscanalsosometimesbecausedbyapartialorintermittentinsertionofthedriveinto
theXT2640–itisrecommendedtocheckiftheconnectionsareclean).
USBDEVICEINCOMPATIBLE. Thisindicatesthatthedrivehasenumeratedcorrectly,butthatthedriveiseithernotdetectedasa
MassStorageClassdeviceorhasmultipledrives,andsoisnotcompatiblewiththeXT2640.
USBDRIVEMOUNTING. ThisindicatesthattheXT2640hasdetectedthedriveandisattemptingtomountthedrive.For
somedrivesthiscantakeseveralseconds,portableharddrivescantakeevenlongerasthedrive
mustachievethecorrectrotationspeedbeforeitwillmount.
USBDRIVEINCOMPATIBLE. Thisindicatesthatthedrivehasbeencorrectlydetectedandhasbeencorrectlymounted,but
inspectionofthedrivehasnotfoundavalidFAT32partitionfortheXT2640touse.Thedrivemay
needtobeformatted.NotalldrivesareformattedwithFAT32whenpurchased(butmostare)so
requireformattingonacomputerbeforetheycanbeusedwithaXT2640.
USBDRIVEREADY. Thisindicatesthatthedrivehasbeensuccessfullyenumeratedandmountedandiscompatiblewith
theXT2640.Thereisaverysmallpossibilitythatthedrivemayfailcompatibilityatsomelaterpoint
intime,suchaswhenreadingorwritingfiles,butthishasneverbeenseenandisveryunlikely.
Note:
WhiledataisactuallytransferringbetweenthedriveandtheXT2640thebackgroundoftheUSBDriveInfoareaflashesa
darkmarooncolor.Donotremoveadrivewhilethisiscolored.ManydriveshaveanLED(orsimilar),onmanydrivesthis
indicatesactivitybutonsomedrivesthisindicatesconnectionstate.DonotrelyonaLEDmountedonthedrivefor
decidingwhetheradrivecanbesafelyremoved.
IfusingacomputerrunningWindowstoformatadrive‐
Dependingonthesizeofthedrive,thedefaultforWindowsmaynotbetheFAT32format.Inthosecasesyou
shouldensurethattheFAT32formatisselectedbeforestartingtoformatthedrive.
Forbestperformance,theAllocationUnitSize(orclustersize)shouldbesettoasettingof8kbytesorhigher(for
mostdrives16kisoptimalforspeed).
ForreasonsunknowntoXiTRON,somedrivescannotbeformattedbyWindowstotheFAT32format.Inthose
casesyoumayneedtoobtainathirdpartydriveformatapplicationtoformatthedrive.Thereareseveralthat
arefreeofchargeavailableontheinternet.
23.3 FILES
TheXT2640onlyoperatesonfilesintherootdirectoryofthedriveandonlyusesthe8.3filenameformat.
TheXT2640doesnotincludetheabilitytoformatadrivenorforfilemanagement.Theseactionsshouldbeperformedusinga
computerifrequired.
Note:
Bydefinition,8.3filenamesarenotcasesensitivesotheuseofuppercaselettersisrecommendedinfilenamestoavoid
confusion.
Thefollowingfilenamesmaynotbeusedexceptforspecificfiletypes–

23.4 CHECKINGTHEDRIVEFILESTRUCTURE
Ifadriveisaccidentlyremoved,ortheXT2640haspowerremoved,whileactivityisinprogressthenitispossiblethatthefile
structureofthedrivehasbeendamaged.Itisrecommendedtouseautilityprogramonacomputertocheckforandrepairanyfile
structuredamagewhichmayhaveoccurredifthisissuspected.
23.5 EXPORTINGFILESTOADRIVE
ThisisachievedbypressingtheUSBDriveInfoareawhileadriveiscorrectlyattached.Thisinitiatesascreenwhichallowsyouto
exportfiles.
