CPR5SA Frequently Asked Questions

Q: What kind of drives can be used with the Compact RAID?
A: The Compact RAID can accommodate up to five 2.5andrdquo SATA or SSD drives that are 9.5 mm in height. Compact Flash cards can also be used on CF media mounted in Addonics CF to SATA adapters and brackets.

Q: What is the maximum size of HDD I can use with the Compact RAID?
A: There are no drive size limitations for the Compact RAID.

Q: Does the Compact RAID require software to be installed?
A: In Windows, the Compact RAID does come with software that can be used for RAID management and advanced RAID settings. It also logs events that occur within the system. RAID configurations can be done without the use of the software.

Q: How do you set up a RAID configuration without using the software?
A: RAID configurations can be created by the use of simple DIP switches located on the rear of the Compact RAID.

Q: Once I configured my RAID set and I'm able to access it in My Computer in Windows, would I be able to connect it to another system via eSATA?
A: Yes. Once the RAID configuration is set up, the entire RAID set can be moved to any computer and connected via eSATA.

Q: Are there other ways to connect the Compact RAID to other ports besides eSATA?
A: Yes. Addonics offer a variety of optional cables and USB adapters that would allow the Compact RAID to be used with SATA, USB 3.0, and USB 2.0 ports.

Q: I have connected multiple hard drives into my Compact RAID and want to see them individually. Why am I only able to see one of the drives?
A: The Compact RAID uses port multiplier technology. The individual drive configuration is available only when connected to a motherboard or controller card that is port multiplier compatible. The Addonics controller cards with Silicon Image Sil3124, Sil3132 chip set are PM compatible.

Q: I have created a RAID volume but an unable to see the full amount disk management but am only able to see approximately 2TB.
A: Only seeing 2TB of disk space can be caused by Windows has a 2TB File System Limit. This occurs in Windows 32 bit systems. In that case, volume sizes greater than 2TB should be converted to a GPT partition. However, not all Windows has the capability. Windows 7 (32-bit and 64-bit) and Windows XP (64-bit) has the capability of converting volumes into a GPT partition. It might be necessary to first move the volume to a system to create the GPT partition before moving it to the desired system.

Q: Are you able to boot from the GPT partition that is larger than 2TB in size?
A: Because of the File System Limit, Windows is not able to boot from a RAID volume larger than 2TB that is created using a GPT partition.

Q: Does Linux systems experience these same problems as the 32-bit Windows system?
A: Once Linux is installed, Linux has a utility that enables to user to convert the volume to a GPT partition. It is possible to boot from a GPT disk, but it is not recommended. Since there is no established method to boot from a GPT disk, Addonics will not be able to provide support for such cases.

Q: What happens to my RAID set if the Compact RAID becomes defected? Will the RAID set be lost?
A: If a Compact RAID becomes defective, you are able move the drives to a new Compact RAID. The metadata is still on the hard drives and could be read from a different Compact RAID device without reconfiguring the RAID set.
