 Nice box.  The specs and googling around don't say what type of interface it 
 uses internally.  Should be SATA, but it could be anything really.  You could 
 write to them and ask.  Or open the case and see what the existing drives 
 are, then buy drives with the same type of interface and try 'em...

Drive upgrade

2011-02-13 Thread John Carmonne
I have two acomdata 2TB drives that consist of 2 1TB Hitachi drives. Each of 
the drives mount as single 2 TB drives. Can I replace the two 1TB's with two 
2TB's and create a single 4TB drive just by installing the new HDD's? Or do I 
need to do a special initialization, if so how would I do this?

You're terminology is a bit muddied.  From what I can tell, you have 
two Acomdata boxes.  Each box contains two 1 TB HDs, that are RAIDed 
together, so they each present a 2 TB volume to your Mac.


1) Replacing the 1 TB mechanisms with 2 TB devices might be possible 
- if their controller supports that.  Best to check with them. 
http://www.acomdata.com/


2) To make a 4 TB from that, you'd have to RAID together two already 
RAIDed boxes.  I don't think that will work.  To RAID things without 
risking data loss, the RAID controller needs to have direct access to 
all the media.

I do have two boxes containing 2 1TB drives each. I want to install 2 2TB 
drives in each box giving me 2 separate 4TB boxes.  Assuming the Acomdata boxes 
controllers will work. Can I just install them and have them mount as a 4TB box 
or do I need to use Disk Utility to create a RAID?

G4 intenal hard drive upgrade

2009-06-15 Thread joan

Would love some suggestions on what to get to upgrade my 867 Power PC
G4. We just added more memory and have 2 GB. The Bus speed is 133 MHz
and I'm using 10.4.11. We have external LaCie and Maxtor hard drives
but would like to beef up the G4 itself.

thanks,
joan

10.4.11 works very well. I use it every day as my mail handler.

What I have done is piggy-back a 500 GB drive on top of the 160 GB  
main drive.

Today, I would piggy-back a 750 GB drive.

As usual, there is the issue of LBA48, and for that purpose I use the  
NVRAM strings.

But, there is now a free driver for MacOS so you won't have to but  
High Cap.

You would still partition your drive as if you were using High Cap:  
the first partition would be 131,072 MB and the second partition  
would be the remainder of the drive.

With the NVRAM strings, you may be able to use the entire drive as a  
single partition.

I haven't tried that, but I can't think of any reason why it wouldn't  
work as the LBA48 properties are added persistently to the MacOS ROM.

Three options, none of which require a PCI card:

Perhaps you should use Google on Overdrive or another search key.
