23.1 DRIVECOMPATIBILITY
AwidevarietyofdrivesarecompatiblewiththeXT2640.Thesemustmeetallofthefollowingrequirements‐
 ThedrivemustbedirectlyconnectedtotheFrontPanelUSBPort,ahubmustnotbeusedandanextensioncableisnot
recommended.
 MeettherequirementsoftheUSBMassStorageClassspecificationandbeasinglephysicaldrive(somemulti‐driveconvertors
cannotbeused).
 MeetUSB2.0orhigherusingfull‐speed(notethatifmarkedasHighSpeedthenitalsomeetstheFullSpeedrequirement).
 Requirelessthan500mAofpowerfromtheUSBport(someUSB3.0drivesdonotmeetthisrequirement).
 Thedrivemustuse512bytespersector(thisisarequirementoftheUSBMassStorageClassbutthereareafewdriveswhich
donotusethissectorsize).
 Thedrivemaybepartitioned,butonlythefirstFAT32(asdefinedbyMicrosoft)partitionwillbeusedanditmustbe<4Tbin
size.Inmostcasesyoucanreformatthedrivetomeetthisrequirement.Generally,drivesorpartitions<1Gbytecannotbe
formattedwithFAT32however.
23.2 CHECKING DRIVECOMPATIBILITY
IfadriveiscompatiblewithacomputerthatdoesnotnecessarilymeanthatitwillbecompatiblewiththeXT2640andviceversa.
TheXT2640requiresthedrivetomeetasmallsub‐setofthestandards,soevendrivesthatdonotfullymeetthestandardsareoften
compatible.
ThebestmethodtocheckifadriveiscompatiblewiththeXT2640istoinsertitintothefrontpanelUSBdriveport.TheUSBDrive
InfoareaonanymainscreenoftheXT2640showstheconnectionstatus.
Theindicationsareasfollows(assumingnodataloggingisactive)–
NOUSBDEVICEATTACHED. TheXT2640hasnotdetectedthatanydeviceisattached,typicallytheXT2640willdetectadeviceis
attachedwithinabout1second,ifthedriveisattachedbuttheXT2640remainsshowingthisforan
extendedperiodoftimethenthedriveisnotcompatiblewithUSB2.0full‐speedoperationand
shouldberemoved.
USBDEVICEATTACHING. ThisindicatesthattheXT2640hasdetectedthedeviceasbeingattachedandisperformingtheinitial
USBenumerationofthedevice.Thistypicallytakesabout1second,butonsomedrivesmaytakea
littlelonger.
