5. Frequently Asked Questions (FAQ)

Q: Why won't the computer let me eject or unmount my drive?

A: There may be a software application running in the background

with an active link to the drive.

Sometimes, you may see a message such as "The disk is in use and

could not be ejected. Try quitting applications and try again." Try

invoking the Force Quit feature in OS X to see what software may be

running. For Windows, the equivalent command is CTRL-ALT-DEL.

Drives connected to the computer via eSATA cannot be ejected in

Windows the way FireWire or USB drives can. However, freeware

utilities are available on the internet that provide a similar function.

Q: Does my 4-bay RAX unit support RAID?

A: The models covered in this manual support only JBOD functional-

ity. However, the drives can be RAIDed in software, or RAX can be

attached to a RAID HBA for hardware RAID functionality.

Q: Will this product work with hard drives larger than 2.2TB?

A: Yes, assuming the rest of your configuration (e.g. OS, BIOS, host

drivers) supports large volumes, this product is compatible with

drives larger than 2.2TB.

Q: Why is my hard drive experiencing data corruption?

A: Many things can cause data corruption on hard drives, whether

they are inside your computer or inside an external storage

product. Malicious software, OS bugs, failure to properly discon-

nect external devices, or no reason at all. Data corruption or loss is

therefore not covered by warranty (this is the case with all rational

companies in the storage industry).

The first thing to try is restarting both the computer and the

external device. If the data is still corrupted, try running built-in

OS utilities (such as Mac OS X's Disk Utility First Aid) on the hard

drive. For best results, boot your computer with a Mac OS X Instal-

lation CD, and launch Disk Utility from the CD. When you reach the

Mac OS Installation program, you can run Disk Utility from one of

the menus at the top of the screen. From Disk Utility, you can run

"Verify Disk" and "Repair Disk" to find and fix any errors that may

be present in your Mac OS installation.

If the OS utility doesn't help, you may need Data Rescue. This is

a great solution for recovering lost data from a hard drive which

has suffered data loss or corruption. If there is a true hardware

failure of your hard drive that prevents it from communicating

with your computer, there is no software solution in existence that

can fix this problem. However, since we cannot tell you with any

certainty whether or not you are experiencing hardware failure in

your particular hard drive, we would encourage you to download a

free demo version of ProSoft's Data Rescue from www.prosofteng.

com. It is limited, in that it only allows you to recover one file per

session, but it will tell you if it even sees any files.
