Description du projet

CrystalDisklnfo is disk utility that supports some types of USB connections, Intel RAID, and NVMe. If anything abnormal is detected, it will notify you by text or voice message, and it supports both HDD and SSD. In addition to information like model number, volume, buffer size, it obtains S.M.A.R.T. information such as how many times the power was turned on, the time length of use, and temperature to monitor the state of the disk.

  • Important Notice

Both CrystalDiskInfo and CrystalDiskMark are open source software personally developed by me. Any software development demands huge amount of time and effort, and on top of that, new hardware devices are released one after another which becomes a necessity to purchase in order to support them. Therefore, this project needs more development funds. As to current status, this project is extremely short of funds and is in desperate need of your donations.

If you want to contribute to supporting the continuance of this project, please make donations by Paypal. Please make the amount of each contribution $10 USD or more (in JPYen, 1000Yen or more) if possible. Your contributions will be deeply appreciated.


CrystalDiskInfoは、ダウンロードメニューから入手できる。作者のサイトからはインストーラ版をダウンロード可能だが、機能面での違いはないため、ここではポータブル版で解説する。 ダウンロード ポータブル版... Montrer comment installer


CrystalDiskInfoを起動すると、システムドライブを含むHDDやSSDの情報が即座にチェックされ、下図のようにメインウインドウで表示される。ウインドウ左上の「健康状態」が「正常」であればS.M.A.R.T.の情報に問題... Show Usage

Amazing program. Unbelievably useful, especially when you know what the values mean. I'd definitely recommend adding more user friendly readouts for the more obscure things (I had to do some research to find out what some of the codes meant) but honestly I can't find fault with the program. Anyone who doesn't like the readouts was just too lazy to find out what they meant.

The manufacture uses the batch number for their hard ware serial numbers. So, I'm not quite sure...
