I-O DATA NAS, with power adapter and instruction manual. - Model Name: HDL2-A - Brand: I-O DATA - Color: Black - HDD: 2TB x 2 - RAID: RAID1 (Mirroring) - Accessories: Power adapter, cable, CD, instruction manual, 1m LAN cable Thank you for viewing. This is a used item, reset to factory settings and confirmed to be in normal working condition. (Notes) ■ Although set to RAID1 (mirroring), this product also supports RAID0 (striping). (Requires reformatting) However, although the HDDs show "no errors" in the check disk, they are quite old, and using RAID1 (mirroring) is recommended. One of the HDDs has been replaced after failing. I was really glad I had set it to RAID1 at that time. ■ Access from Windows 10 and 11 may require some extra steps. Searching for "Cannot access LANDISK" will yield various information. A printout of the documentation from the I-O DATA website is also included. The key points are: ・Enabling SMB1.0 (use at your own risk due to vulnerabilities) ・Adding Windows credentials I have not confirmed access from Mac or smartphones. ■ The original box is not included.
