Q: How do I connect the GPT50 to my eSATA equipped computer?
Use an eSATA cable (not included) between the eSATA port on your computer and the port on the drive. We
strongly recommend you use high quality external SATA cables. Low quality cables do not offer the proper
shielding and durability that high quality cables offer, and may allow data to be corrupted.
Q: How do I connect the GPT50 to my USB equipped computer?
Use a USB cable (not included) between a USB 1.1 or 2.0 port on your computer. The cable needs to have an
“A” connector at the computer end and a “B” connector at the drive end.
Q: My Windows computer doesn’t show the drive in My Computer. What’s up?
The default format on the GPT50 is for the Macintosh, and Windows doesn’t recognize it. Once you have
connected the GPT50 to your Windows PC, you have to re-initialize it for use with Windows. For most ver-
sions of Windows, that’s going to be NTFS format; for Win98/SE, that will be FAT32 format. Instructions for
re-initializing your drive are included in this manual.
Q: I’m still running Mac OS 9 or Win/ME. Can I still use the GPT50?
Yes. You can connect the USB port on the drive to your OS 9 or Win/ME machine.
Q: What are the differences between FireWire 800 and FireWire 400?
Speed and Protocol. FireWire 800 has a max transfer rate of 800 Mb/sec (about 100 MB/sec peak). FireWire
400 has a max transfer rate of 400 Mb/sec (about 50 MB/sec peak). The higher bus speed helps with things
like large file copies and RAID, where FireWire 400 bus speed can be a limiting factor. FireWire 800 uses IEEE-
1394b “Beta” protocol; FireWire 400 uses IEEE-1394a “DS” protocol.

posted there concerning FireWire 800/1394B, as well as information about the rest of Glyph’s product line.
Q: How can I make my drive work across Windows and Mac platforms?
The only file system that works well between Mac OS and Windows is FAT 32, otherwise known as MS-DOS
file system. This is a native Windows file system, but Mac OS 9 and X will mount FAT 32 volumes. Mac OS 9
and 10.1.x would only work with FAT 32 partitions less than 32GB. While Mac OS 10.2.x increased that limita-
tion to 128GB, it wasn’t until Mac OS 10.3.x that you could use FAT 32 partitions of any size. Mac OS 10.3.x
can additionally read NTFS volumes but cannot write to them. See next question for information specific to
Pro Tools software.
Q: How can I use my drive with Windows and Mac Pro Tools systems?
If you are trying to use a hard drive between Windows and Mac Pro Tools systems, FAT 32 will not work for
you because a Mac running Pro Tools can only work with HFS formatted volumes. Your best option is to in-
stall MacDrive (www.mediafour.com) on your Windows machine to mount your Mac formatted volumes.
