READ10 and Write10 SCSI Commands

NTDEV
1

I am new to SCSI command to DeviceIoControl API.

Will the SCSI Command support USB Memory Stick Device to READ10 WRITE10 operation?

or only bulk read and bulk write only possible?

2

From what level? From the disk class driver, a USBSTORAGE device is a
standard scsi disk device, That is the perspective above usbstor. From
below usbstor it is all bulk usb operations, as defined in the usb
specs.

Mark is right. If you have a disk class lower filter you’ll get all the SCSI
commands.

I am using device path to create handle for the device as below…

\?\storage#removablemedia#7&7274f86&0&rm#{53f5630d-b6bf-11d0-94f2-00a0c91efb8b}

So i feel it will work from USBSTORAGE driver.

CreateFile(DevicePhysicalPath,
GENERIC_READ | GENERIC_WRITE,
FILE_SHARE_READ | FILE_SHARE_WRITE,
NULL,
OPEN_EXISTING,
NULL,
NULL);

I am able to send INQUIRY and READ10 command.
INQUIRY is working fine.
READ10 working if i pass LBA value 69 (0x45) then it read from MBR of USB stick.
WRITE10 is try to write into CDROM the handle is same as READ10 and INQUIRY.

I suppose you are using spti. How you prepare the parameter for READ10 and
WRITE10? Show more code or details.

READ10 SCSI example.

  1. In this code DeviceIoControl API return error. Error msg is “The semaphore timeout period has expired.”
  2. Is there any pre-requisite to send READ10 or WRITE10.
  3. TEST_UNIT_READY and INQUIRY Command are working fine.

SCSI_PASS_THROUGH_DIRECT_WITH_BUFFER sptdwb;
PUCHAR dataBuffer = NULL;
ULONG length = 0,
errorCode = 0,
returned = 0,
sectorSize = 512;
BOOL status = 0;
ULONG alignmentMask = 0;
ULONG c_lba =1;

dataBuffer = (PUCHAR)malloc(512);

ZeroMemory(&sptdwb, sizeof(SCSI_PASS_THROUGH_DIRECT_WITH_BUFFER));
//ZeroMemory(dataBuffer,sectorSize);

sptdwb.sptd.Length = sizeof(SCSI_PASS_THROUGH_DIRECT);
sptdwb.sptd.PathId = 0;
sptdwb.sptd.TargetId = 0;
sptdwb.sptd.Lun = 0;
sptdwb.sptd.CdbLength = CDB10_LENGTH;
sptdwb.sptd.DataIn = SCSI_IOCTL_DATA_IN;
sptdwb.sptd.SenseInfoLength = 32;
sptdwb.sptd.DataTransferLength = SECTORSIZE;
sptdwb.sptd.TimeOutValue = 60; //interval in seconds
sptdwb.sptd.DataBuffer = dataBuffer;
sptdwb.sptd.SenseInfoOffset = offsetof(SCSI_PASS_THROUGH_DIRECT_WITH_BUFFER,ucSenseBuf);
sptdwb.sptd.Cdb[0] = 0x28;
sptdwb.sptd.Cdb[1] = 0; // Data mode
sptdwb.sptd.Cdb[2] = (UCHAR)(c_lba >> 24) & 0xFF; // MSB of lba
sptdwb.sptd.Cdb[3] = (UCHAR)(c_lba >> 16) & 0xFF;
sptdwb.sptd.Cdb[4] = (UCHAR)(c_lba >> 8) & 0xFF;
sptdwb.sptd.Cdb[5] = (UCHAR)(c_lba) & 0xFF; // LSB of lba // Zero means MBR. Very careful when write operation.
sptdwb.sptd.Cdb[6] = 0x00;

sptdwb.sptd.Cdb[8] = (UCHAR)(SECTORSIZE) & 0xFF; // Parameter List length
sptdwb.sptd.Cdb[9] = 0x00;
