Q: I'm having trouble seeing my disk when connected via eSATA
A: eSATA host connections require the SATA host bus to support
and have AHCI mode enabled and active. Additionally, the eSATA
cable must be a proper shielded cable, 1M or less in length, with
a blade depth (the recessed plug of the cable) of 1cm.
Some host bus adapters have built-in RAID functionality and must
be configured before the disks will appear to the host computer.
For these cases, the eSATA controller will have either a BIOS
utility or a software RAID configuration utility that will need to
be configured prior to use. Please consult your eSATA host bus
adapter documentation for more information.
FAQs for Mac Users:
Q: Why is my drive asking me to format it? It was already
formatted and it contains data.
A1:Run a disk repair utility on the drive.
A2:Perform permission repair on your system drive. Open the
disk utility (located in /Applications/Utilities/Disk Utility.app.)
Select your system drive (usually the first disk listed) and click
"Repair Disk Permissions" in the "First Aid" Tab.
A3:Restart your computer. As soon as the bootup chime sounds,
press and hold down the option-command-p-r key combination
to reset the PRAM. Release the keys when the chime sounds
a second time. Please refer to your Mac manual for more
information on these procedures
Q: My computer does not recognize the drive.
A: Check to make sure that all of your connections are secure
and that the power switch is in the "ON" position. Then check if
your External Hard drive is listed in the Apple System Profiler. If the
problem persists, verify that the appropriate port used is functioning.
Q: I'm trying to copy files to/from FAT32 volumes or network
shares, and it keeps failing.
A: FAT32, HFS+, and other file system formats allow different
standards of filename length or use of special characters.
Rename the offending file(s) and try the operation again.
