As you may have noticed from my previous post I've been playing around with my network and DROBO backups lately. I have two DROBO's (ver.2) for data storage and backup. I have never had much of a problem with these, though I've seen problems listed on the web. I suppose I have been lucky, for these last few years, until now..... I noticed my main DROBO, (connected to win7 desktop), had two corrupted folders. Of course I was in the middle of organising my files and backups, so I hadn't backed up those folders. Luckily, I have GetDataBack on my windows machine, so after an initial panic, I was actually able to copy the folders over to an external drive. I do not believe that I was writing to the DROBO or there was a power problem, so I am at a loss to why this happened. It simply seems to have decided not to like those folders anymore. So....... I am currently left using any blank HD's I have lying around to make sure I have two copies of all my data. (The second DROBO seems fine, but I'm not going to take that risk.) If I was a millionaire I would run out and buy a few 2TB drives and do a transfer, but I am left using up a mishmash of drives, while keeping a note of where every folder is, (as well as its backup). The only thing I can think is that either the DROBO actually was interrupted while writing to those folders, or the drives are starting to get flakey. I have previously purchased SpinRite 6, so I am running a lvl 4 test on the drives, (although this looks like its going to take a lonnnnnng time). From what I can see its going to take, (4*2TB).......37 days to test all 4 drives. lol That's really all on the windows side, (basically because I happened to have the tools at hand), but does anyone have DROBO experiences like this, or any suggestions what I can be doing on the mac side, (apart from struggling to organise my data)? With every step taking so long, (DROBO throughput being a problem at times like these), I would like to do more than one job at a time. I did get the itch to build a high capacity NAS box and use the DROBO's as backup only, and that's when I discovered the HD price rises. Just my luck that this didn't happen six months ago..but at least I'm safe and my data is restored.
