Thanks Jon.
I did already read through that manual, but it is really a specs sheet. The actual manual is here: https://www.stardom.com.tw/stardom_products_data/sohoraid_series/sr2/2011_sr2_manual_en_fr_ge_sp_cth_ja_ko.pdf
I followed the instructions up to step 4. The manual then says, “When the SR2 has completed initializing, your computer’s operating system should recognize the device automatically. Please follow the formatting instructions given by the operating system to format the drives. Once the formatting has been completed, the system is ready for use.”
Well, my 64Bit Win7 system, via USB3.0, recognises that the SR@-WBS3 is connected, but no disk shows up in “Computer”, so I cannot format the drives. 🙁

Volume information shows nothing, I assume as disks aren’t formated:

“Computer” shows no SR2-WBS3 attached drive connected:

Any thoughts? Is USB3.0 campatible with drives over 2.19TB on Win7 64bit?
Thanks,
Paul.
