I recently purchased drive.     LS420D (LS420DD23) Version 1.81-0.03  It is running fine.

I have 2 hitachi 3tb DT01ACA300 drives that I would like to use in it

I switched to JBOD, powered the unit down, removed drive 2 (1tb stock drive) and replaced it with the 3tb

Powered it back up and according to NN2 its in EM. Cant login to the unit via web browser.  Can ping.

I tried this a few times all with the same result

Removed 3tb drive and unit is back running fine with no problems.

Note: the three tb drives are not empty. They are from my work server which was never used. They do have data and probably partitions on them. I currently do not have a way to wipe them. HDD enclosure is in the mail should be here friday

Will formatting them allow my current method to work? What format should I use?

Thank you


Edit: I am following the instructions on this thread and waiting for my enclosure to arrive.

Are either of the two methods on that thread preferred? I edited ini file and made the debug changes. Is there risk involved with that procedure?

If following that procedure, should I have both 3tb drives installed while performing the procedure?

Erase both NEW drives, not the original drives, using this method: http://buffalotech.com/support-and-downloads/faqs/cleaning-a-disk-in-windows-7-using-diskpartexe (http://buffalotech.com/support-and-downloads/faqs/cleaning-a-disk-in-windows-7-using-diskpartexe)

Should work with any version of Windows.

If the unit still boots with the original drives, put in one original drive and one new drive.

Format the new drive.

Shut it down and replace the original drive with the other new drive.

It should now boot and you can format the other new drive, then create a RAID 1.

This worked perfectly thank you

Glad we could help.
