Hi All,

What I'm looking to do is to span a folder across ~three hard drives. What I want to be able to do is open up a folder and view the merged contents of all there hard disks, and when I write to this folder I'd like to have been able to specify an order of preference (although it's not critical) so that it initially tries to write to c:\, but if that's full it will roll-over to d:\, or if that's full it will roll-over to e:\. It needs to be readable (but not necessarily writeable) on a network too.

I think I can do a similar thing with RAID0/JBOD but I don't want to lose any data if one of the hard drives crashes or I take one out; I'd still like to effectively be able to see all three drives separately but to also have a merged view of them. I don't really want files to be split across the drives when they're being copied either; I'd like complete files saved on a single hard drive rather than being split across them all.

As an example:

The contents of c:\myvideos
-video1
-video2

The contents of d:\myvideos
-video3
-video4

I open up the merged drive view and its contents will be:
-video1
-video2
-video3
-video4

I try to write to the merged drive and it will copy initially to c:\myvideos but if that is too full to fit the file it will try to use d:\myvideos instead.


I guess I could just buy a bigger hard drive rather than faffing around with three, but hey :D.
Thanks :).
 
afaik, it's not possible..

i'd just buy some new big hd's (two of them) and robocopy one to the other every day (will copy new files to the 2nd one) so you've got a daily backup
 
Oh ok. The reason I want this is that my TV card eats a stupid amount of space and often I come home to find it's not doing anything because there's no free space, despite there being lots free on other drives.



No doubt this is killing my system performance, too.

I'm not necesarily looking at a backup system; I stupidly follow the "it's never happened to me yet" approach and favor the extra space, but that's probably a very good idea.
