Re: Western Digital "MyBook" as RAID?

Hello Folks,

Looked up and down the web, called the mfg, read all the docs I could find. Still no idea. Maybe someone else is already using the Western Digital "My Book World Edition" as a LAN file server and has an idea. Here's the scoop:

I just bought the 500MB version which contains one HD. They also have a 1TB version with two HD in there but I do not like the idea to rely on RAID within one machine. Ok, it's Linux based but would share the motherboard and other stuff. Not so good IMHO, plus they didn't have it.

Now the docs say you can configure even this 1 HD version for RAID although that only creates two mirrors on the same disk. Doesn't make too much sense to me. Additional HDs can be connected via a USB port but there seems to be no information whatsoever on how to use such an external HD as the second drive for RAID. Any experience?

In a recent thread the Netgear SC101 was suggested. I studied that a bit and found too many posts on the net where the whole thing had fried up and none of the disks were readable, which would kind of defeat the whole purpose of RAID I guess. Anyhow, there aren't too many LAN drives out there and I want to avoid a big box. Also, there were some warnings in web discussions that one should decide on the configuration before actually doing it because it's supposedly hard to undo.

Software RAID like you're talking about just duplicates files so if one gets corrupt you have the other to recover from. Like synching files in two locations but without the benefit of the two locations.


Yeah, and I've been through a few HDs that literally came to a grinding halt. One really screeched. All backed up so nothing was lost, but one still learns from that.


From what I hear from friends working in the IT World "Software RAID" should be avoided if possible from the many problems it seems to have.

If you just like the idea of duplicate files why not get two Network attached HD and schedule a script (or tools that provide scheduled services) to copy files from the "working" drive to the backup drive on a nightly/weekly basis?


That's what I will probably do if I can't get a HW RAID going between its internal HD and a USB disk. It would have been nice to have RAID though because there are days here in the consulting office where a layout is done and tons of intermediates are created. Those need to be backed up at least hourly.
