External Hard Drive Questions
 
Hi Forum,

I am a switcher (and happy) and still encounter loads of windows machines in my day to day work (in the IT field)

I recently purchased a 500GB External hard drive. I plugged the drive in and was excited to see that the HDD was formatted in FAT32. So I was happy because of FAT32 being an open format which would be read/write compatible with no matter what OS I encountered and had to work on.

My question firstly, I thought that FAT32 wasn't implementable on any drive over 40GB ???
Secondly, is there any problem with running FAT32? Isn't is a very old and antiquated format?
Thirdly and lastly, is there any speed decrease with having a 500GB drive in FAT32 format? (shouldn't I rather split the drive 50/50 and have one for Windows Things in NTFS (which I can READ under Mac) and 250GB in a Mac HDD Format?

I am busy transferring data a large amount of data to the drive on a Windows machine and the transfer rate is bobbing between 11megabytes/serc and 13megabytes/sec
Now, given that this is a 2.5" hard drive (USB powered) I can understand that there MIGHT be some type of performance decrease when compared to a 3.5" external powered drive. But to put it into perspective, I am used to seeing speeds of 25 to 35 megabytes/sec on the 3.5" drives (running NTFS)

Now, my OFFICIAL last question ( :D ) - is this speed decrease because it is running FAT32 on such a large partition or because this is just normal with the smaller 2.5" external USB powered drives?

Your expert opinions and answers appreciated and thanks in advance,

Chris Grant

I'm not too sure about having speeds decrease because of it being a FAT32 partition. It could be any of the things that you mentioned. Is the drive 7200 or 5400rpm?

Hey, thanks for the reply!
The thing is, it's a 2.5" drive so it is highly likely that it is 5400rpm and highly likely that it spins even slower than that.

My main concern is the fact that I am now running a drive with FAT32 (which I abandoned using when I moved to Windows XP... so my questions were mainly meant to direct towards the "is FAT32 really a trustworthy and decent Disk Format to use. I have since repartitioned the drive to include a partition of FAT32 and a partition in Mac OSX Journalised Format so that I can use it with Time Machine.

Guess that my worries were a little silly to begin with :P

I probably would have partitioned the drive as well. NTFS is much more stable than FAT32 file system. Plus, now you have a drive for your Time Machine backups!
