Naraeon SSD Tools internals – 7. Get diagnostic information(SMART) from SATA devices

Necessity I think this part doesn’t need any further explanation about necessity. Because this part is the reason of existence of disk management tool. With this, we can manage devices’ status, and catches subtle failures that can be easily ignored by users, to prevent big failure. S.M.A.R.T: Self-Monitoring, Analysis, and Reporting Technology As the name […]

Naraeon SSD Tools internals – 6. Identify SATA devices

Necessity Last time, I introduced ATAPI command standard, ACS-3. I said about some definitions and introduced how we can issue a command to SATA devices. In this time, we would see implementation to issue identify device command in Naraeon SSD Tools. Identify (Identify device) In fourth, I said about Identify command like this. BIOS and device […]

Naraeon SSD Tools internals – 5. Introduction to SATA commands

Necessity Though NVMe devices are now widely spread, SATA devices are majority. Most of the SSDs connected with PC using SATA interface, and definitely HDDs do. To get information about them, knowledge about their language, ACS(ATA Command Set) is mandatory. Naraeon SSD Tools implemented based on SATA, and results from other devices converted to SATA […]

Naraeon SSD Tools internals – 4. Command set and Interpreting buffer

Necessity I think reason for visiting my blog is in this. Function that includes all features other than Read, Write, Open, Close, ioctl. Called DeviceIoControl in winapi. In undergraduate course, there would be only introduction about this function. I also firstly had no idea about where to find information to use ioctls. So I would write about […]

Naraeon SSD Tools internals – 3. Physical drive abstraction

Necessity Physical drives have various features. From these features, TPhysicalDrive abstracts some of them those are needed to Naraeon SSD Tools. Internally, the object just passes the request to right object. There are objects process these requests. Firstly, there is an object that issue adequate command to the bus directly(ATA, SCSI, NVMe, …).  And there is […]

Naraeon SSD Tools internals – 2. Objects pointing path

Necessity Naraeon SSD Tools has various objects those need path. From TPhysicalDrive as the name shows, a lot of Getter objects need the destination drive path. Other than that, some objects require path of a partition. In those cases, it is reasonable to memorize the path and use many times. Someone would think this is […]

Naraeon SSD Tools internals – 1. How to get PhysicalDrive list

Foreword In this series, I would write about internals of Naraeon SSD Tools. So people who implements some subset of this would get some help. This series includes things I asked about. If you have further questions, feel free to email me. But I would not get request about translating code snippet from Delphi to […]

Introduce Naraeon NVMe Tools

Naraeon NVMe Tools is an open source NVMe SMART / Health Information Log Viewer on Windows. Download: Basic tab provides basic informations like Model, Speed, Status. So you can diagnose your device easily. Driver tab provides informations about storage driver. You can find the details of your storage driver without Device Manager. Critical Warning […]

Intel 750 Series’ NVMe Commands

This time, I’ll talk about Intel 750 Series’ NVM Express Admin Command. Passthrough By now(Dec 2015), there’s no official way to do NVMe Passthrough. So Intel 750 Series use the way that used by nvmewin. To try NVMe passthrough to nvmewin-like driver, see this document. Above document says \\.\scsi address is needed to passthrough. You […]

Get PCI express link width / specification version Programmatically

Many people include me find how to get PCI express link width / specification version programmatically. But there’re too many useless articles. Like examples about NetworkAdapters(I applied “-NetworkAdapter” and 90% of search results are gone!). And some of the remaining results say it must be solved with drivers. Others say just give up windows and […]
