SETUP – MK3021GAS (HDD2181) Caution: Your Hard Disk Drive is a precision device and even a small drop onto any surface can cause damage. Electronstatic discharge can also damage the drive. You should ground yourself prior to handling the drive. Master/Slave Settings Your Toshiba Hard Disk Drive can be configured as either a "Master" or "Slave" unit.
Installation Notes The drive should be mounted carefully on the surface of 0.1mm or less flatness to avoid excessive distortion. In order to prevent short-circuit under any circumstances, a space of 0.5mm or more should be kept under the PCB. Space should be kept around the drive to avoid any contact with other parts, which may occur due to shock or vibration. The temperature of the top cover and the base must always be kept under 60C to maintain the required reliability.
USING THE HARD DISK DRIVE – MK3021GAS (HDD2181) Backing up Data Files To avoid data loss, regularly back up the data files on the hard disk drive.
TROUBLESHOOTING – MK3021GAS (HDD2181) Problem My system is not able to recognize all available capacity on my Hard Disk Drive. What do I need to do to utilize the complete hard drive? How do I install my 2.5" Toshiba Hard Drive into my desktop or tower system? 5 Solution There are some systems that are unable to recognize the new larger Hard Drives on the market. 3rd party software is available that breaks the "capacity barrier".
