Q: Can you recommend an add-on card that is compatible with MB491V5K-B?
A: Please click the icon below to view the compatibility of your motherboards or add-on cards that support PCIe Bifurcation mode. For the best compatibility, we highly recommend using the cables recommended or manufactured by the motherboard or add-on card manufacturer.
We are currently in the process of certifying our NVMe enclosure with major add-on card and motherboard manufacturers. We will keep updating the list to include compatible accessories.
To report a compatible add-on card, cable, or motherboard, or to check the compatibility of add-on card(s) or motherboards that are not listed, please click here.
Q: I've completed the installation of the hard drive and device as per the instructions in the product manual, but the system still can't detect the drive. How can I troubleshoot this issue?
A: Please first confirm the compatibility of your hardware, and make sure that the drive, drive enclosure, cable, and host interfaces are compatible. Try connecting the drive directly to the host to see if the system can detect the drive. If it still doesn't detect it, this can rule out issues with the drive enclosure. You can also try connecting the drive enclosure with different drives, cables, or systems to see if the issue can be resolved. If the system still can't detect it, here are some possible issues:
| • | Insufficient PCIe lanes in the system: Whether you're connecting the drive enclosure to the motherboard or add-on card, It is important to note that the number of available PCIe lanes is limited. This includes understanding the number of lanes provided by the CPU and chipset, as well as their allocation method. Failure to do so may result slower transfer speeds, unstable connections, or even the inability to detect the drive. |
| • | Incompatible interface protocols: It is crucial to verify whether the Mini-SAS HD, OCuLink, or SlimSAS interface on the motherboard or add-on card is capable of supporting NVMe. |
| • | Incompatible interface pinout standard: Prior to connecting the drive enclosure to the Mini-SAS HD, OCuLink, or SlimSAS port on the motherboard or add-on card, please verify that the port utilizes the same pinout standard as the port on our drive enclosure. To check the pinout standard of our drive enclosure, you can refer to the specification table on our product page, where it specifies whether the pinout standard is Legacy or SFF-9402 1.1. |
| • | Excessive length of the connecting cable: To ensure optimal performance, it is advised to use a connecting cable that is no longer than 50cm. Using longer cables can lead to excessive signal loss, resulting in slower transfer speeds, unstable connections, or even the inability to detect the drive. Additionally, we recommend using the same interface connector for both the device and the host to prevent any potential compatibility issues. |
Q: I'm using Intel/Broadcom Tri-Mode HBA and RAID cards with the MB491V5K-B, but the drives do not show up in my system?
A: The issue is caused by RAID card manufacturers using a different pinout for Tri-Mode cards than is typically used for U.2 connections. When using these cards with U.2 NVMe drives and cables, a U.2 enabler cable must be used for compatibility, which reverts the pinout back to standard U.2 specifications. For more information, please click here.
Q: My NVMe drive did not detect after inserting it back into the device while powered on?
A: For systems that support hot-plug function, while your system is powered on, each drive insertion and removal cycle will require a manual refresh from the operating system in order for the system to recognize the drive.
If you are unable to detect the drive after performing the manual refresh, your system might not support hot-plug functions. We suggest you check with the motherboard/add-on card manufacturer to see if it supports the NVMe hot-plug function.
Windows 11 / Windows 10 / Windows 8 – In the search box on the taskbar, type Device Manager, then select from the menu, right-click on the disk drive and then select scan for hardware changes.
Windows 7 – Right-click on computer icon on desktop and select properties, click Device Manager, right-click on the disk drive and then select scan for hardware changes.
Q: The mounting screws for the device seem to be too short to secure the device onto my system, what should I do?
A: For computer cases that have a thick metal sheet, the included mounting screws (M3*2.5L) may not fully secure the device. Please use longer screws (M3*4L) to secure the device or contact us at tech@icydock.com for replacement screws.
Q: I feel that the drive tray's upper and lower metal spring is stuck when inserting the drive tray. What should I do?
A: Remove the drive tray from the enclosure and reinsert the tray without putting excessive pressure on the metal mesh sheet in front of the tray. Excessive force on the front metal mesh sheet may bend the top and bottom metal spring, causing difficulties when inserting the drive tray. Therefore, please do not forcingly insert the drive tray when this happens as it may cause damage to the metal spring.
