The Cirrus Logic chip is probably for the IDE interface, whereas there are dedicated chips for spindle motor, voice coil motor control and possibly even head driver/amplifier. There is a Hyundai memory chip, likely to be used for cache. The underside is a plethora of ICs, with a pair of Atmel flash chips and Motorola microcontrollers in control. It even has a 32kB cache.Īmazingly, specifications can still be found on Computerhope and Red Hill Technology’s websites. The power requirements are a very modest 410mA on the 5v rail and 215mA on the 12v rail, no doubt because its spindle speed (3600rpm) is probably quite slow by modern standards. Its geometry is 685/16/38 giving a size of 210Mb (hence the model number CFS210A). Manufactured in Singapore on Week 25 of 1994, this drive is 20 years old. I was expecting this one to be dead … but no. The main philosophy in Conner drives was to reduce cost by innovation – their “flat” base and tub-shaped lid were ways to reduce the cost as it didn’t require milling out or casting a complex base, and their use of microcontroller firmware based servo, spindle and self-test operation was also a distinguishing feature. Miniscribe itself was purchased by Maxtor in 1990.Īside from that, Conners were not popular choices amongst system builders and were more often the cheap, slow and sometimes unreliable choice. Interestingly, Conner was reabsorbed into Seagate in 1996. I did have contact with a 40Mb Miniscribe Winchester hard disk, but lets just say that their company’s accounting operations became famous when it collapsed. Conner Peripherals was started up by Finis Conner, the co-founder of Seagate Technology and merged with CoData which was a Miniscribe-based startup. Very often, they would be included as Compaq were a significant backer of Conner. Conner CFS210AĬonner Peripherals drives were a common sight if you worked around Compaq branded computers. Definitely a trip down memory lane for some of these drives, and others, completely fascinating. As part of a large bundle of stuff which was generously salvaged on my behalf, these are the hard drives that I managed to get.
