| | SCSI write blocker, computer forensic investigation protection and preservation |
 | | Paralan's SCSI Write Blocker allows data to be read at full speed, however, it will block any and all write commands thus preventing the possibility of writing to, or formatting the drive under examination. | | | To prevent any system problems when write commands are ignored, a false acknowledge of writing is reported to the host computer. | | | By using a Hardware Write Blocking interface, Computer Forensic Investigation may be accomplished without fear of compromising the data on the drive. |

| | Maxtor Showcases Engineering Samples of Serial Attached SCSI Drives At HP World 2003 |
| | Building on the company's accomplishments in being first to market with the previous three generations of SCSI interfaces, Maxtor engineers were able to successfully initialize the target device, execute SCSI commands, and read and write data across the interface. | | | "Adaptec continues to work with technology leaders like Maxtor to drive Serial Attached SCSI development and bring the performance, flexibility and scalability benefits of the next-generation storage technology to our customers." Maxtor recently announced it reached a SAS engineering milestone when it successful exchanged SAS data packets between two prototype devices. | | | For more information on Serial Attached SCSI, please refer to the Maxtor website at: http://www.maxtor.com/en/technologies/serial_attached_scsi/index.htm About Maxtor Corporation Maxtor Corporation (http://www.maxtor.com) is one of the world's leading suppliers of information storage solutions. |

| | Linux sg3_utils package |
| | Unix dd command variant, uses SG_IO ioctl to send SCSI commands to do reads and writes when instructed. | | | [In version 1.14 sgm_dd also use the sg driver's asynchronous (write()/read()) interface but that has been changed to the SG_IO ioctl in version 1.15 since the asynchronous action is not needed. | | | The SCSI generic (sg) interface still represents a cleaner interface than the primary device names since the drivers behind primary device names have their own policies, may interfere with error processing and in some cases run their own state machines. |

| | How can I get my Jaz drive to work with Linux (or another OS...)? |
| | However, the commands they provided don't seem to work (probably (ab)user error, knowing my level of SCSI programming knowledge). | | | In the meantime, the only thing to do is find a Mac or PC with a SCSI interface and use Iomega's Jaz Tools software to disable the write verify mode. | | | Recent models of the Jaz drive (with firmware version H.71 and later) are shipped in a so-called "write-verify" mode. |

| | iSCSI: All you need to know about iSCSI |
| | NFS and CIFS were designed to transfer complete files (as in NAS), while iSCSI was designed to transfer data between servers and storage systems at the block level (as in SAN), similar to how servers read and write to internal disk drives. | | | Answer: iSCSI (Internet SCSI) is a protocol that encapsulates SCSI (Small Computer System Interface) commands and data in TCP/IP packets for linking storage devices with servers over common IP infrastructures. | | | iSCSI, a block based storage protocol, is superior in speed (up to 10 times faster) to NFS, CIFS file-based protocols. |

| | Hale's HIW: CHS Translation |
| | The CHS used at the INT 13H interface is converted to the LBA that is used in the SCSI commands. | | | LBA addressing is also used at the INT 13H interface by the AH=4xH read/write calls. | | | The LBA value produced in step 1 is the same as the LBA value produced in step 3. |
