Hitachi Deskstar 7K1000.C, model HDS721032CLA362, 320GB 3.5" internal desktop hard drive. 7200 RPM, 16MB cache, SATA 3.0 Gb/s. Firmware JPFOA3EA, P/N 0A39264, MLC JPT3EA, Type DS7SAC320, dated June 2010, made in China by Hitachi Global Storage Products (Shenzhen).
PLEASE READ BEFORE BUYING - THIS IS A HIGH-HOURS DRIVE. SMART reports 57,801 power-on hours, which is roughly 6.6 years of continuous runtime, over 825 power cycles. This almost certainly came out of a machine that ran around the clock. I am stating it plainly up front rather than burying it, because it is the single most important thing to know about this drive.
The counterpoint is that the SMART table is genuinely clean. Reallocated Sectors: 0. Current Pending Sectors: 0. Offline Uncorrectable: 0. UltraDMA CRC Errors: 0. Reallocation Event Count: 0. Health status reads Good and the drive was running at 27C. Every attribute is passing above its threshold, and the drive reads and writes normally across the full 320GB. High hours on their own do not make a drive bad - what matters is whether those hours produced damage, and here they have not. A CrystalDiskInfo screenshot is included in the photos so you can check every number yourself.
Given the hours, I would treat this as a secondary or scratch drive - a spare, a test bench disk, a CCTV or DVR drive - rather than the only home for anything you cannot lose. Keep backups, as you should with any used drive. It is a standard 3.5" SATA drive that fits any desktop PC, enclosure or recorder that takes one. Fully tested and securely wiped before shipping. Sold as-is with no warranty. Ships from Tel Aviv, Israel. Only the drive is included - no cables, screws or mounting hardware.
