Cantar-X User Manual v2.44 (r14) 2013 March 21
p.43
p.43
Preliminary notes:
FAT32 can handle up to 2TB, but
Microsoft lets it be 'universal' below 120GB, Cantar formats
the drives up to this value only.
To install a SATA drive, replace the internal Cantar FireWire-
to-PATA bridge with a FireWire-to-SATA bridge.
Primary Storage
HD
PATA
• Seagate EE25.2 [ST980818AM] 80GB.
SATA
• Hitachi Endurastar J4K100 100GB, 4200RPM
• Hitachi Travelstar 5K320 [HTS543216L9A300] 120GB,
5400RPM.
When replacing a HD, verify the static electricity ground
connection between the disk housing and the Cantar chassis
is within factory specs (120k ohm ±20%).
SSD
PATA
• Transcend TS128G PSD320 128GB.
SATA
• Crucial C300 128GB.
Some SSDs don't work with the Cantar FireWire–>SATA Oxford
bridge, contact Aaton before buying!
Backup Storage
Internal CF card
Run 'Idle Bckp' or 'At Call' on CF cards; faster than DVD-
RAMs they help you be ready at wrap (p.54).
One thing physical to check: when the Cantar is on, does
the CF Tray's LED stay on at all times? If so, then that will
keep the Cantar from formatting the CF. The red LED should
only come on when the Cantar is accessing the CF tray
(read/write/format).
note:
contrary to a suggestion found in former manuals,
do not
backup on SD cards
, CF to SD converters are not reliable.
Internal CD DVD DVD-RAM
ATAPI connected Panasonic UJ-85J. When switching from TEST
to PPR, the unfinished Idle Bckp is closed but the motor gener-
ates magnetic interference for five seconds; that is the mu-metal
shield raison d'être in Cantars #001 to #240 (p.58).
To edit the DVD-RAM from a FireWire connected Majax, put
the Cantar CPU in its TECHSET.01 '
Unmount
'-ed state.
External DVD
If an external DVD burner containing a blank disk is FireWire
connected, and if there is no media in the internal burner,
Cantar creates the backup on the external burner.
External HD
Use a well ventilated enclosure such as the
Cantar-Cellar
(picture above) made of a Cantar HD shuttle and a protec-
tive housing. The shuttle can be separated in a wink to be
immediately used as the Cantar internal HD.
With a large HD (e.g. 250GB),
use Partition-Magic
http://www.symantec.com/norton/partitionmagic.
Format
a 40GB FAT32 primary partition and the rest under NTFS.
The workday is recorded on the FAT32 partition, and off
hours you transfer it to the NTFS partition.
Some good advice:
Oil bearings of a unused HD Disk
become stiff, imagine the fate of your archives if you don't
run your disks once a year.
Media
CF cards
Select 30 or 60MB/s Sandisk or
Lexar cards (64GB max. capacity).
To erase the data,
do not delete
the
files, re-format the card (p.37).
Optical Disks
Never use supermarket branded media.
CD-R:
Made by Taiyo Yuden, select Maxell 'Pros'.
DVD±R:
Ask the Post Production supervisor what is his
preferred flavor (+ or –). Taiyo Yuden 8x are the best. For
better lifespan Cantar only burns DVDs at 4x.
DVD-RAM:
Panasonic 3x LM-AF-120LE.
Optical Disk Handling
98% of all media failures are caused by poor handling. A
fingerprinted DVD can still be played but is unuseable for
recording. Open your thumb and index-finger in a U-shape
and hold the blank disk by its opposite edges. Do NOT
clean it with a cloth in a rotary motion (best way to destroy
a complete track) but by successive radial strokes.
DVD-RAM & Mac
DVD-RAMs are read-only on Macs. To edit metadata install
