The three Western Digital eSATA (external Serial ATA) Hard Drive models (DVR Expander) that FiOS recommends for DVR expansion were discontinued by Western Digital. In fact, it looks like WD has dropped all SATA drives.
But there are SATA external Hard Drives on the market from Fantom and Iomega. And probably others. And plenty of hard drive enclosures to convert to SATA. So what is Verizon's updated list of recommended manufacturers and models?
