A3000T + Deneb
« on: September 02, 2008, 04:27:33 PM »
I am thinking of ordering a Deneb USB for my 3000T. I was wondering if os3.9 would recoginize a large external HD or would it still be limited to 4 gig partitions?

Two and a half limiting factors:
a) the file system must support TD64 or NSD. The FFS of 3.9 or BB1/2 does (NSD). SFS does too (NSD (and older versions TD64))
b) the device driver needs to support TD64 or NSD. usbscsi.device does since the very first version (>6 years).
c) the SCSI commandset currently limits transfers (with 512 byte physical blocksize) to 2 TB (two Terabytes).
d) SFS has a maximum partition size of 128 GB (at least with 512 byte blocks).
e) Windows XP itself only allows FAT(32) up to devices with less than 32 GB capacity, otherwise only NTFS can be used. That's no limitation of the filesystem but an arbitrary limitation of windows -- you can still format it to FAT(32) using a DOS tool.

So in short: yes, you should be able to use these large harddrives with the Deneb.
