Drobo

Reuse drives from a Drobo disk pack for other purposes

Today I upgraded one of the four drives in my 2nd gen Drobo. I’d like to reuse the drive that I swapped out of the Drobo on my Mac.

I put the drive in an external enclosure and connected it via USB. Now neither Disk Utility nor diskutil recognize the drive – it simply does not appear in the list.

Can I reformat the drive? Or is a drive effectively bricked after it’s been used in a Drobo?

Couldn’t find any previous thread, if there is one, please point me towards it.

Thanks

Alexander

it just appears totally blank to your OS right now

you need to first partition it then format it

Thanks, but i might not have been specific enough: I can’t repartition the drive as Disk Utility doesn’t see it. Console prints the following messages when I plug in the drive.

Any hints as to why the OS doesn’t connect to the USB drive? The enclosure works, I have been able to use it with a drive identical to the one that’s causing the problems.

No idea, something evidently isnt compatible.

but basically sorry, its not drobo - drobo’s drive just appear at totally blank - no partitions, no nothing, thats all it does to them though.

can you connect the drive directly to an SATA controller - or is it a laptop/imac or something?

Docchris,

thanks for your idea. Turned out the enclosure is faulty. Specifically the USB/SATA Bridge. When connected via eSata to a PC, Vista recognized the drive and I could repartition and format it.

Thanks!

glad it’s sorted :smiley:
