DETAILS This Toshiba hard drive (HDD) was used in Denso navigation radios in GM vehicles. We have too many of these in stock, so we're blowing them out. If you've researched specialty hard drives, you know this is an insanely low price for a new one. We are told these are ATA locked. There is evidently a technical process to remove this lock (ATA secure erase?) but it is not necessarily quick and easy. Either way, the drive is exactly what we say it is and we've sold BUNCHES as proof. (As seen in the sales history of this ad alone...) Here's what Toshiba has to say about this product on their website: "Toshiba's MKxx60GSC series Serial ATA hard disk drives target today's increasing capacity needs of in-vehicle applications with a 4,200 RPM spin speed...and a standard 2.5 inch form factor. The MKxx60GSC drives offer the highest capacity point available for the ruggedized, automotive-ready disk drive segment and provides premium vehicle systems manufacturers with the high-capacity storage needed to improve telematics, navigation, and entertainment systems. Fueled by consumers' desire for multimedia applications and navigation systems physically integrated into their cars, the MKxx60GSC series drives represent a significant innovation in commercial automotive-grade hard disk drive technology.Technical benefits include improvement in internal transfer rates over prior generation models, a faster seek time of 12-milliseconds, and an extremely quiet 'sleek silent' operation of 23dB. All Toshiba automotive-grade hard disk drive models are suitable for use in industrial applications where an extended temperature tolerance of -30 to 85 Celsius is required." Some specs: 100GB storage capacity 9.5-millimeter high profile 8MB cache buffer Extended temperature operating range (-30 to 85 C) Extended altitude operating range (-300 to 5,500 meters) Shipping Policy: We ship fast.
