Valuable_Old-Mac Compatible_FW400 & USB_250GB External Hard Drive Thank you for viewing. ■ This is an old product, so it is recommended for those who are familiar with it. Operation has been confirmed with both FW400 & USB 2.0. Although the frequency of use was low, the internal HDD is thought to have deteriorated over time, so please consider it as a bonus. ■ New IDE-HDDs are difficult to obtain, but you can replace them with inexpensive, modern, large-capacity SSDs by using a 2.5-inch SATA-SSD + IDE conversion board. ■ The case is made of extruded aluminum with an anodized finish, making it scratch-resistant and excellent for heat dissipation, giving it a very high-quality feel. ・ Manufacturer: MATHEY ・ Internal HDD: 250GB_WD2500_IDE connection_Bonus ・ Accessories: AC cable, FW400 cable
