Drive Not Detected
The installed HDD or SSD fails to appear on the host computer because of failed interface electronics, poor carrier seating, damaged connectors, or loss of the SATA/SAS data path.

Repair, Service, and Parts
Acme Revival is an independent repair network that operates separately from the manufacturers whose devices we service. Our independence enables a repair model that exists beyond manufacturer-controlled strategies, while preserving the ability to work with manufacturers where appropriate.

Secure Data Storage
End Use Segment
CRU Data Security Group is a U.S.-based storage-hardware OEM founded in 1986 that specializes in secure removable data-storage and physical data-transport systems. Its CRU product line includes removable drive bays and carriers, rugged external storage systems, encrypted portable drives, secure drive enclosures, write-protection hardware, and related storage solutions designed to let organizations physically remove, transport, protect, and control access to sensitive data. CRU products are particularly associated with government, military, defense, intelligence, law-enforcement, digital-cinema, and commercial computing environments, where removable storage and long product lifecycles are important. The company says millions of its removable-drive products have been deployed worldwide, and its current portfolio emphasizes physical data security, tamper resistance, ruggedization, and integration into long-lived computing platforms.
2 Most Seen Failures:
Cooling Fan Failure
Internal or bay cooling fans stop operating or fall below their expected speed, commonly triggering a flashing status LED or audible fan-failure alarm. Continued operation can lead to excessive drive temperatures.
Power Failure
The enclosure or removable-drive bay fails to power up because of a failed AC adapter, internal power connection, power circuitry, or key-operated power switch. Symptoms typically include no LEDs and no drive spin-up.
RAID Degraded or Failed
Multi-drive DataPAK, RTX, and ToughTech systems can enter a degraded or failed RAID state when a disk becomes unreadable, develops damaged sectors, or drops from the array. The system may generate an audible alarm and require drive replacement and array rebuilding.
Carrier Connector or Bent Pin Damage
Repeated insertion and removal of DataPort carriers can damage or bend electrical contacts, preventing reliable power or data communication between the carrier and receiving frame. The drive may become intermittent or disappear completely.
Encryption Key Recognition Failure
Secure DataPort, RTX Secure, and ToughTech Secure models may fail to recognize the hardware security key, preventing the encryption processor from accessing the installed drive. CRU documentation identifies missing, damaged, or unreadable keys and key-interface faults as causes.
Overheating
Hard drives and enclosure electronics can reach warning or alarm temperatures because of failed cooling, restricted airflow, or prolonged heavy operation. ToughTech and other monitored CRU products can illuminate warning LEDs or sound temperature alarms when thresholds are exceeded.
SATA/USB/eSATA Interface Failure
A failed or intermittent interface connection can cause disconnects, missing drives, unstable transfers, or complete loss of host communication. Faults may originate in the enclosure interface board, external connector, cable connection, or carrier-to-frame data path.
Hard Drive Failure
The HDD or SSD installed inside the CRU enclosure can develop unreadable sectors, mechanical faults, or electronic failures that cause a "Failing" status, RAID degradation, or complete loss of drive detection. CRU RAID products specifically monitor for these disk failures and initiate degraded-state warnings.

- 1 Repairs are performed on a best-effort basis. Acme Revival utilizes a network of sophisticated technicians and engineers with diverse service offerings; despite this, factors that influence the repair outcome may ultimately prove unsuccessful. Acme Revival makes no claim that it can, guarantee a repair before your device is sent in for diagnostic evaluation; even then, repair and diagnostic work are not mutually exclusive. Despite well-intentioned quoting, repairs may still prove unsuccessful.
