Hi Denn,
Sorry, just seen your posting from a couple of days back.
Yes, I've got two 1tb disks, one is a Seagate and can't remember the other, but they both just plug in either of the USB sockets. I generally use the rear one for tidiness and leave the cable in place when I remove the disk cos it's messy to try to find the socket again when you are leaning over the T4 from the front. Spare leads are only a few pounds/dollars. In fact, if memory serves, I'm sure I've had them both plugged in simultaneously at some time or the other.....(What is handy, is that, when 'experimenting' on the PC on a single or just a few files, download them to a memory stick and plug it into the front USB)
Fred is of course correct advising that the limit of files in a folder is under 250 but, I've found that it's a lot easier to arrange files/folders on the PC.
I have'nt touched T4/PC stuff for 6 months or so because of a house move and the turmoil that causes, but I had previously got to my 'aim' which was to keep a 'mirror image' of the Seagate on the PC and do all my editing thereon and then just dump the whole lot, in one, to the Seagate. As a good way of keeping backups, housekeeping etc etc under control, it's quite a good habit. Also, using some of the free software available on this website, it's quite powerful. I generally use my laptop, so, very often, you will find me sitting in front of the tv and messing with stuff, particularly Registrations which, in my opinion, is the way to go. It's also a very good way of keeping up with what MP3's, WAV's and MID's are on there, not to mention the ability on the PC/Laptop to print out some of the database using a spreadsheet/word processor as required.The main reason I went this way is that, I'm from an IT background and I just find it easier to 'picture' the folder/file location, file names, structures etc on the PC rather than the T4 which 'loses me' so very often. I know that the structure is, basically, the same, but it's just how things sit in my minds eye and are able to be portrayed on a reasonable size screen.
I hope this helps..... I'll get the model numbers of the drives and post them on here a bit later.
Best wishes - Jim
