Hi, this whole firmware thing is really getting confusing. I had a failed update 12-10 last December and then 2 days later the 12-10 update installed successfully. I had a 10-24 "hardware" update install successfully on Jan 01 and then a 10-24 hardware update install successfully on Jan 15. On Jan 21 I had a successful install of the 01-18 firmware update and now this morning (24th) I have another successful install of the 01-18 firmware update. Is this all correct and if yes, why do I have what appears to be two successful and identical firmware updates within a few days of each other? Unit is 256GB SP2. I'm getting confused..... Thanks!
