Writes a Sector (512 Bytes) from SRAM starting at the address, to which the content of the variable wSRAMPointer is pointing to the Drive to sector number lSectornumber. The functions returns 0 if no error occurred. For Error code see section Error codes.

[[File:Notice.jpg|left|Notice.jpg]] This is not the address of wSRAMPointer, it is its content, which is the starting-address of the buffer.

 

 

= Partial Example =

 <source lang="bascomavr">
Dim bError as Byte
Dim aBuffer(512) as Byte' Hold Sector to and from CF-Card
Dim wSRAMPointer as Word' Address-Pointer for read
Dim lSectorNumber as Long' Sector Number

' give Address of first Byte of the 512 Byte Buffer to Word-Variable
wSRAMPointer =VarPtr(aBuffer(1))

' Set Sectornumber

lSectorNumber = 3

' Now Write in sector 3 from CF-Card
bError = DriveWriteSector( wSRAMPointer , lSectorNumber)
