Hello there!
I've been in love with my Mac mini since I bought it last December, but recently I've hit the upper limit of the internal 160GB hard drive, with only 5GB free space remaining. I've got 2 1TB external hard drives, one of which I use as a Time Machine backup drive. Instead of the very laborious process of clearing space on the internal drive, I thought I could use Disk Utility to create a concantated disk set to "extend" the logical capacity of the internal hard disk and attaching one of my external USB hard disks so I wouldnt have to re-arrange the file structure extensively and/or pick and choose files to delete to create usable space on the small-ish internal drive.
Unfortunately, I'm having difficulty establishing a JBOD RAID array with Disk Utility. Strangely, my mac mini has a RAID utility program preinstalled, but it generates an error message saying its not supported on this computer. I'd like to create a dedicated 500GB partition on my Mac OS Extended (journaled) formatted USB Hitachi 1TB drive to increase the storage capacity of the internal 160GB drive without having to delete anything at all.
I opened Disk Utility, selected RAID from the "Macintosh HD" (internal drive) and then dragged the external USB hard drive into the RAID: Macintosh HD window that was created. An icon appeared in the large box entitled "new member: disk2s2" and the instructions say to enable the (external 1TB disk) disk as a "degraded RAID set" or click on the new disk2s2 icon and click the "enable" button to enable a new RAID set. Since I'm using about 200GB of the 1TB disk already as my Time Machine backup, I absolutely dont want to risk losing the data there by enabling (or later disabling) RAID for that disk, and I'm unclear as to what may happen (irreversible changes) if I select "enable".
Alternatively, I could format my yet-unused second 1TB drive and use it in this way rather than risk trying to establish a 500GB concantated partition on the external drive that has 200GB used for my Time Machine backup. I dont want to risk losing any of my files or TIme Machine backup data
I would also like to establish a sizable Boot Camp partition on the external drive, which I havent got around to doing yet.
I also have an older model Lacie 300GB drive with FireWire 800 ports on it, which has backup files from my 2006 MacBook Pro 17 (long since gone). Maybe a silly question, but is there a significant data throughput speed advantage in using that FIreWire 800 interface with the older drive or should I stick with the newer (dec 2009) 7200rpm Hitatchi 1TB drive with USB 2.0 only interface?
Also, how feasible is it to open the mini and upgrade the existing drive with a larger capacity drive? I was also considering buying a server-version of the Mac Mini and networking the 2 computers, or perhaps a 27" i7 iMac
I am DESPERATE for quality technical advice on these issues. PLEASE help me and post your replies here on this thread. Many, many thanks in advance for your help, time, and consideration.
Kind Regards,
