How many gig HD can I...

You can't use FFS with large partitions because the disk validator (even with OS39 and BB2) can't handle it. If you get a single write error, then goodbye. Crash, reboot, crash, reboot, etc.

So atleast use SFS. It doesn't even get unvalidated. You can reset while writing something and the only effect is that the file you wrote is chopped off, not lost. It's that safe. It also got a salvage utility so you don't have to worry about not being able to use f.ex. Disksalv.

Also, SFS and PFS is multiple times faster than FFS. Using FFS with a new HDD is a bad move for performance. Reading your average download directory of +2000 files only takes a second or two using PFS/SFS. Using FFS it's more like >10 seconds.

Using a four gigabyte partition may work most of the time, but not all the time. Some software may use a signed 32-bit variable instead of an unsigned so one fine day you end up with a corrupted HDD.

> can I at leat take my 40 gig and make like 10 or 20 partitions each 2gig in size?

Yes, alot of people do this. Note that partitions have to be exactly 2gig in size, not just 2gig-ish. Also, if you make a workbench: with 512MB then the trailing partition have to be 1536MB, not 2048MB.

But I recommend using far less space for the workbench though. Like 128MB, or even 64MB if you don't plan to upgrade to AOS39.

@ellis: It's important to know that the filesystem is actually installed to the HDD partition and read by the OS when mounted. So there's a trick to it in HDToolBox. You have to add it to a list of filesystems, then edit the partition to use the filesystem, and stuff like that.

Anyway, nobody can remember how they did it the last time they did it and it's hard to explain even over the phone :-)
