connecting to an external freecom hard drive

I have just bought a 250gb classic SL external hard drive to back up data on my ibook and pc (XP). I have connected the drive to my ibook using the usb cable supplied but a new icon hasn't appeared so presume the drive hasn't been mounted.

I have checked system profiler, device and volumes and the drive is listed so appears to be connected.

Hi Farv,
I missed the fact that you are running Jaguar. Jaguar won't see FAT32 formatted drives larger than 128GB. So, what can you do? First, you could partition the drive with one HFS+ and one NTFS partition. Or, you could use NTFS and connect the firewire drive to your Windows PC and share it over the network with your Mac. As long as the disk is not locally connected to your iBook it will read and write to a NTFS formated volume just fine.

Petra - thanks for the advice though I think I need to ask a couple more questions. I understand that I can't connect directly to a drive that is NTFS formatted. If I were to partition and create one NFS+ (?) and one NTFS partion how would go about this ? My other option is to try and setup a PC / Mac wireless network which has baffled me so far.

Thanks.

Hi Farv,
First let me stress, that I haven't tried this myself. I found this procedure in a german mac forum and people reported that it worked for them. The way to go is to partition the drive on the Mac, and to create one HFS+ partition (that is the OS X file system) and one FAT32 partition for Windows. Then you connect it to your Windows pc and convert the FAT32 partition to NTFS (Windows XP preferred format). You will need to use the terminal to do so.

Before you type anything, be sure to read the full text.

To create one FAT32 partition with 30GB capacity named "WIN" and one HFS+ partition with 20GB capacity named "MAC", you would type the following into the terminal:

diskutil partitionDisk disk1 2 MBRFormat MS-DOS WIN 30G HFS+ MAC 20G

and hit return

The volume number disk1 has to be replaced by the one used by your Mac.To find the right number type the following in the terminal, first with your external hd disconnected, and then with your external drive connected:

ls -la /dev/rdisk?

Without your external volume you will get something like this:

PowerBook:~ ebbi$ ls -al /dev/rdisk?
crw-r----- 1 root operator 14, 0 28 Sep 20:14 /dev/rdisk0


With your external drive connected it will look similiar to this:

PowerBook:~ ebbi$ ls -al /dev/rdisk?
crw-r----- 1 root operator 14, 0 28 Sep 20:14 /dev/rdisk0
crw-r----- 1 ebbi operator 14, 4 28 Sep 20:48 /dev/rdisk1


In short, the new number you get, is the right number to use.

Beware: If you use the wrong number, eg. the drive number representing your internal HD, you will completely erase it and loose all your data.

When the formatting has run its course, disconnect the drive and connect it to your windows machine and convert the FAT32 partition named "WIN" to NTFS.

Hi Farv,
Dr Smoke explains three more options for sharing an external drive between Windows and OS X. In short, one is to format the whole drive as FAT32 with all it's limitations, the second is to format the drive in MacOS extended (aka. HFS+) and to use a special software on the PC to access that drive, and the third is to share the drive over the network. The last one might be of interest to you, as he gives a lot of links that explain how to propperly set up such a network.
