Frequently Asked Questions (FAQs)

What is the expected lifespan of a 4TB hard drive?

Most mechanical 4TB hard drives have an average lifespan of 3 to 5 years under normal operating conditions. Factors such as workload intensity, environmental conditions (temperature, humidity), and power cycling frequency significantly impact longevity. Drives used in NAS or surveillance systems typically come with higher durability ratings (e.g., 60–180TB/year workloads) and longer warranties. In comparison, SSDs generally last longer (up to 10 years) due to the absence of moving parts.

Why doesn’t Windows 10 recognize my 4TB hard drive?

This issue is commonly caused by partitioning limitations. Traditional MBR (Master Boot Record) only supports drives up to 2TB. To use a 4TB drive fully, it must be initialized using GPT (GUID Partition Table). Other possible causes include outdated BIOS/UEFI firmware, loose data/power cables, incorrect SATA port configuration, or driver issues. Ensure your motherboard supports UEFI mode and update your system BIOS to the latest version for optimal compatibility.

How do I verify a supplier's authenticity and production capability?

Always request:

• Business license verification
• Factory audit reports (e.g., SGS, Bureau Veritas)
• Product certification documents (CE, FCC, RoHS)
• Samples before bulk ordering
• References from existing clients, if available

Platforms like Alibaba provide verified "Gold Supplier" badges and transaction history, but independent due diligence remains essential for high-value contracts.
