Can I replace the hard drives in my DriveStation Quad by myself?

During the warranty period, please contact Buffalo Americas and we will replace any defective drives for you. The drives are easily replaced by sliding them into their bays behind the removable front panel; no tools are required. If maintaining your warranty is no longer a concern, most 7200 rpm SATA drives from reputable manufacturers will work fine in the DriveStation Quad; a screwdriver will be required to remove the hard drive tray and place it on the new drive. Because of thermal and power issues, the use of drives with speeds higher than 7200 rpm is not recommended.

Do I have data redundancy in RAID 0 mode?

No. While RAID 0 mode gives you more disk space, it will provide no data redundancy. Please, configure your DriveStation Quad for RAID 5 or RAID 10 to keep your data most secure.

Do I need to format the DriveStation Quad before I can use it?

All Buffalo DriveStation products come preformatted FAT32and are ready to use. It can also be reformatted to NTFS or HFS+ easily from any Windows® or Mac computer.

Is the DriveStation Quad compatible with Windows Server 2000, 2003 or 2008?

Yes. The DriveStation Quad works perfectly with Windows Server 2000, 2003 and 2008. The included NovaBACKUP Business Essentials is also compatible with Windows Server.

What capacity will the device have in different RAID modes?

The DriveStation Quad supports RAID0, RAID5 and RAID 10. In RAID 0, all hard drives are combined to provide maximum storage equivalent to the stated capacity of the device. However, in RAID 0 there is no data redundancy. RAID 5 provides data redundancy by using parity information on all drives and therefore provides 75% of the stated capacity (the equivalent of one hard drive is used for data redundancy). Finally, RAID 10 is available if you would like to combine the drives into a set of striped mirrors. In RAID 10, the volume is equal to 50% the advertised capacity.

Will the DriveStation Quad work on my Mac?

Yes, the DriveStation Quad will work perfectly on your Mac with OS X 10.4.11 and later. However, keep in mind that the DriveStation is pre-formatted with a FAT32 file system. Certain Mac features (TimeMachine) will require that you re-format the DriveStation with your Mac for the HFS+ file system which is very easy to do with any Mac computer.
