That seems to have gotten me access to my drobo again. by the time I got to the end of your instructions it gave me all green lights, and blue lights but drobodashboard and windows couldn't see the drobo so I shutdown my computer (effectively powering down the drobo?) then restarted and now I can access my drobo, albeit in RO mode. Would it be safe, do you think, to put it back in to RW mode? Thx! |

RE: 2nd gen Drobo in perpetual "Data Protection" mode?
ah that is great news (from the accessing the data in read only)
i honestly think the best thing to do right now (if you can still actually access the data) would be to start copying it onto somewhere else while it is accessible. once you have successfully copied your data (which may admittedly take a fair amount of time), then i think you may need to identify a good set of drives and to set up the drobo from scratch again (essentially like restarting and resetting the drobo, but only using a set of drives known to be good) - but you would not lose anything but some time, by trying to take the drobo out of readonly mode.... but please, only try that after you copy your accessible data ![]() (btw i have XP home SP2, a Drobo v1 with 2x 1TB/2x 1.5TB WD greens, & a bkp Drobo v2 with the same + a DroboShare: unused) & a DroboS v2 with 3xWD15EADS &2x1TB in DDR mode on win7, & a drobo5D (all usb)

RE: 2nd gen Drobo in perpetual "Data Protection" mode?
Thanks for all your help. I am in the process of copying things to my server but that will take... forever. I am a bit worried though as one of the drives has gone "red" (bad I assume)(but this is why I got a drobo in the first place so its kosher) so I will check it once I have copied everything.
Question though. I keep trying to find the largest supported drive for Gen2 Drobos and can't seem to find it anywhere. I think I found somewhere before that 3tb drives should work which I can confirm, and I have used 4tb drives no problem. I figure if I am going to have to replace a drive that I should go ahead and "future proof" (proof is relative I know) things by getting a larger drive but I don't know if the Drobo Gen2 can take 5,6,8tb drives? Can you (or anyone) confirm compatibility of drives larger than 4tb? Thanks!!! |

I am a bit worried though as one of the drives has gone "red" (bad I assume)(but this is why I got a drobo in the first place so its kosher) so I will check it once I have copied everything. My set up: Drobo Gen 2 Firewire: WD RED 5TB / WD RED 4TB / WD GREEN 2TB / WD RED 2TB I have successful used a 4 and 5 TB hard drive in a Drobo Gen 2 (Firewire). HOWEVER: I had one of the bays empty and put in a WD 2 TB Green drive. The drobo didn't see it (I know the drive is good since it was just in my Drobo Gen 1). I let the drobo run over night, but in the morning, the WD Green still can't be seen. Therefore, I decided to do a little cleaning. I disconnected my drobo, so I can blow out the dust inside. My WD Red 5 TB hard drive doesn't slide out! I have pushed the side tab multiple times (sliding the drive in and out) but it will only slide out about 1/4 of a inch then gets stuck. I don't want to damage the drive. So I pushed it back in. Blew the dust out of the remaining 3 bays. Put in back all drives and started up again. All drives (including the WD Green) are running with green lights, and Drobo Dashboard can see the drobo. However....What am I going to do with that WD RED 5TB that doesn't want to slide out???

With four 2 TB hard drives, I have seen it work for over a week when the machine is less than half full (4 of 10 blue lights). Sometimes, I would replace a drive with a newer drive (like a WD RED), and would wait for a week before the data protection sequence is done. Therefore, with a Drobo that is just about full, I would expect to wait longer. BTW: I suggest you set up a method of backing up your Drobo, so that if Drobo dies, you don't loose your data. My drobo is on a Mac, and TimeMachine is always backing up this Drobo. I also have another software (ChronoSync) that copies the file to another hard drive on my network in the middle of the night. It gives me peace of mine knowing I have the files since I know that the drobo days are number and reading this forum makes me worry with all the number of people with problems with their drobos.(02-20-2017 05:25 PM)Paul Wrote: thanks for the update, |

RE: 2nd gen Drobo in perpetual "Data Protection" mode?
btw ticzon1 already knows this thread, but there are some gen2 posts here by users with larger drives:
http://www.drobospace.com/forums/showthr...http://www.drobospace.com/forums/showthread.php? however, im think the officially tested drives are 4TB, and a max 16TB volume on that model, and there are some important caveats like certain firmware requirements or settings regarding the type of 4k sector advanced format drives, for example mentioned here https://myproducts.drobo.com/article/AA-01199 and also here: https://myproducts.drobo.com/article/AA-01124 (for ticzon1, just linking to your main thread about a stuck drive) http://www.drobospace.com/forums/showthr...http://www.drobospace.com/forums/showthread.php? (btw i have XP home SP2, a Drobo v1 with 2x 1TB/2x 1.5TB WD greens, & a bkp Drobo v2 with the same + a DroboShare: unused) & a DroboS v2 with 3xWD15EADS &2x1TB in DDR mode on win7, & a drobo5D (all usb)
