Seagate Firmware Update Question

[SSD]

I'm confused.

 

I have 4 Seagate 7200.11 drives:

  2 1T on firmware AD14 (in my array)

  2 750G on firmware SD15 (never opened)

 

I opened the 750G drives today and noticed they were on SD15 firmware.

 

So I started doing some searching and saw that both AD14 and SD15 firmware are both affected (I had checked a while back and had NOT seen AD14 on the list).

 

So I did more searching and found a website where you can enter model and serial numbers to determine if a drive is affected.

 

Both my models reported being possibly affected.

 

Searching by serial number, it says only ONE of the 1T drives (AD14) is affected.  It reports the other 3 are not.

 

I'm totally confused - I thought the problem was BASED ON the model and firmware level, and that I'd need to update all 4 of these.

 

Can anyone help straighten me out?  Should I only update 1 drive?

The gist of what I've read is that the affected drives were tested at the factories with a certain test program, thus not all drives even from the same factory are affected... were I you, I would only update the one drive.

 

That being said, a link to the diagnostic you mentioned would be appreciated and relevant...

I too have read that story that the factory used a test program and didn't properly clear some data. I don't buy it. This would not require a firmware update but rather a utility to fix whatever the test program left behind.

 

Myself, I would just update them all.
