Toshiba MG10ACA20TE

Overview

Toshiba MG10ACA20TE appears here as a 20TB 3.5-inch SATA HDD used mainly in Exxact storage and GPU servers, often inside RAID or hot-spare workflows. Most tickets are not about configuration quirks, but about failed-drive replacement logistics, warranty path, and how to handle degraded arrays without increasing data-loss risk.

Known Issues

• drive hardware failure (~13 tickets) - SMART failure, unreadable device state, red drive LEDs, clicking, failed self-checks, or drives missing from RAID. Examples: #15240, #22483, #24690, #32344, #33995.
• RAID Configuration (~7 tickets) - degraded RAID sets, hot-spare rebuilds, mdadm or controller-reported failures, and questions about replacing drives without collapsing the array. Examples: #18957, #19201, #24615, #32759, #37259.
• Shipping Damage (~2 tickets) - international or freight-heavy logistics where shipment method, serial mix-ups, or package handling materially affected the replacement path. Examples: #29148, #9283.
• storage controller failure (~1 ticket) - one case ultimately pointed beyond the drive itself to repeated SATA-bus errors in the host platform. Example: #37259.

Common Questions

• Can Exxact do advance replacement for this drive? Often yes when the system had advance-replacement coverage or the production impact justified an exception, but not every case qualified automatically. Examples: #15240, #19201, #22483, #24298.
• What evidence is enough to open an RMA? Tickets commonly used SMART output, smartctl failures, RAID-controller logs, red drive LEDs, failed self-checks, or backplane slot errors. Examples: #15240, #22483, #24615, #32344, #32759.
• Do we send back only the failed drive or the whole system? Usually only the failed drive, unless broader bus or platform instability suggested the server itself needed depot testing. Examples: #29148, #31466, #37259.
• What if two drives fail in RAID and removing them is risky? Support sometimes approved advance replacement or exception handling when return-first processing would materially raise data-loss risk. Examples: #18957, #22483, #24615.
• How long will replacement take? Standard cases often flowed through manufacturer turnaround, while exceptions, in-stock swaps, or advance replacement moved faster. Examples: #12778, #24031, #32344, #32759.
• Who pays shipping? Domestic warranty handling was usually straightforward, but international or non-DOA cases could leave the customer responsible for significant shipping cost. Examples: #9283, #29534.

Related Products

• Other Toshiba MG10 20TB variants - customers sometimes needed help matching the exact serial and invoice because multiple similar 20TB drives existed on the same order (#29148, #31466).
• 20TB SATA RAID members in Exxact storage servers - many tickets are really array-maintenance tickets, not standalone single-drive incidents (#18957, #22483, #32759, #37259).
• Boot or cache NVMe drives in the same systems - some failures were handled alongside PSU, NVMe, or broader storage incidents rather than as isolated HDD events (#12778, #37259).
