RAID Data Recovery + SD card

RAID Recovery
Lacie 5 Big Thunderbolt RAID drive will not show up on the desktop. It seems that one of the 5 drives has failed, though all the blue LED lights are not indicating there is a problem. In disk utility, it says that 4 of the 5 drives are online, but one is missing/damaged. I need to see if the information on any or all of these drives can be recovered. And you’re correct, LaCie tech support is useless.

Netgear ReadyNAS 4 disk RAID 5
2 2Tb drives and 2 6Tb drives with 6-8Tb data to be recovered. Debían Linux OS, Configured as Linux_Raid, one drive isn’t readable and one looks potentially corrupt. I would like the data recovered to 2 new 6Tb drives and the two existing 6Tb drives. I believe a software based recovery should be possible. Data is mostly flat files with some application files, no databases in the required data.

Micro SD card recovery
I have two 32GB microSD cards (One SanDisk Ultra, one SanDisk Mobile Ultra), neither of which is recognised (I’ve tried multiple high speed reliable card readers and operating systems). Under linux one is detected as a 32MB (Megabyte) drive and the other reports “no media” as if it were a removable drive. I am an expert user and have recovered data from hard drives in the past so I am confident this is a hardware problem in both cases. I suspect (but cannot be certain) than one of the cards came from my old mobile and has some family photos / videos I would l would like to retrieve. I would be happy working with a raw dump of the card(s) – the type the “dd” tool would produce if the cards were working – so long as *some* of the data can be recovered. I would appreciate any information you can provide in terms of options, likely cost and chances of success for recovering this data.
