Hard Drive Failure Modes

Hard disk drives are mechanical devices and are susceptible to damage from physical shock. One type of physical shock, called operating shock, occurs when the disk is in operation. During operation, the drive head is typically over the drive platters reading and writing data. When a physical shock to the drive occurs during operation, the head and the platters can come into contact causing both components to be damaged. (more…)

Solid State Hard Drives (SSD) in the 722 and 744T

Solid state hard drives, or SSD drives, are becoming a feasible storage medium for portable recorders and computers. Like CompactFlash cards, SSD drives have no moving parts and greatly extend the environmental operating conditions of the recorders. (more…)

DVD-RAM Media Used in the XL-DVDRAM

Q: I’m running an XL-DVDRAM with my 702T, and am using it to copy/back-up the files I record on the 702T. I noticed that you recommend 5X DVD-RAMs for this, but that 3X would work. (more…)
