Buffalo Forums

According to the following wiki (thanks 10000): https://buffalonas.miraheze.org/wiki/Terastation_TS-XEL

Some TS-XELs have onboard NAND, while others do not. From what I understand the onboard NAND makes it easier to recover these devices after complete drive de-population, as the firmware is stored in the NAND. If my understanding is correct...is there a way to determine which units have onboard NAND through external inspection? Or does the cover have to be removed and the mainboard examined to determine the answer?

If you watch the LCD screen while it boots it will display the size of the NAND, I believe mine says 0 or 0MB when it gets to that part.

Good to know. My question pertains to obtaining these units used, without disks installed. Would you have any idea if the unit would test/display NAND size with no disks installed, i.e., would it get that far during boot?

It displays the NAND size before if even scans for disks, right after initializing the memory. If you can power it on and the display works it will tell you.

Here's what it looks like from the serial console:

You can see that it's well after it reports the NAND size that it even checks if drives are present or not.

Thanks for that update including the serial console info :)
