New Samsung 840 Pro FIRMWARE is out.

[Brahmzy]

dumb question can you update the FW on a SATA II setup?

Yep.

[DooRules]

I just used the software. As soon as I boot up the Magician software was giving me a pop up saying new FW.

[Highendtoys]

You shouldn't have any problem updating the drive over SATA II.

Hello,

I flashed my 840 Pro 128GB with the latest firmware, and write performance is lower (less than 40MB/s for Seq and 512k with Crystal Disk Mark and AS SSD). You do not have this problem that I see.
I do not understand

My config is in my signature

thanks

Hey tistou77, you know there is a mod bios on the Asus forum that has the 11.6 raid rom on it...

Hello

The write performance are income "as before" with CDM and AS SSD.
I'll try the bios modded with ROM RST 11.6
This is better than the ROM RSte 3.5?

Thanks

[tistou77]

I tested the bios with ROM RST 11.6, same performance with the ROM RSTe 3.5, except for the 4k write, slightly better

Guys i got very bad news :/ ,""""" BEWARE """" Do Not Update """"" Your Samsungs 840 Pro 256GB to the latest firmware DXM04B0Q , My 2 Samsungs 840 Pro 256GB are " Completely Dead " after flashing both drives with this latest firmware , Just like the guys from Anandtech i secured erased both drives today and Bam , Both Dead as a brick after secure erased. Drives are not recognized by any of my PCs Intel and AMD rigs. They will be RMA by samsung asap. It seems they broguht back the same bug that was on the initial pre-production firmware , exactly this is what happenned to me on both drives http://www.anandtech.com/show/6503/s...0-pro-failures . Just a heads up my drives are only 2 weeks old and have been secured erased only 3 times. Beware. I will post more information onced the guys from Samsung tell me what its wrong with this firmware back on an email i

[DooRules]

Guess I won't be SEing them till I hear an update on this, thanks for the heads up bud.

[canthearu]

Yep, thanks for heads up

Kind of disappointed!

[Live or Die]

Don't know what happened to your drives but i flashed mine to DXM04B0Q did a secure erase as well what program did you use to secure erase your drives the Samsung software?

[jax7480]

I have 2 Samsung 840PRO's 128GB. Did the update and secure erased them from that time, 2 times. No issues at all.

[tistou77]

I never managed to run the secure erase samsung (USB key)

[chispy]

I used Samsung magician 3.2 software to secure erase , i have a few Samsungs 830 drives and have been secure erased dozen of times + and never had any issue , so in fact its not user error its a hardware or software failure guys nothing more nothing less. I have been playing with SSDs for many many years its the first time i see something like this :/. They go in the mail today for rma , my RMA just got approved. I hope nobody else have this issue ( cross fingers ).

Why do you think, that the firmware update has caused the death of both SSD's?
That is why I ask again te question of Live or Die: With which tool have you done the secure erase procedure?

[UNTAMED]

- my 840 pro flash had no issues , besides a small drop in points from as ssd. 1214 to 1204 could need a few days of GC maybe.

[Brahmzy]

Well, I've got 2 of my 5 840 Pros flashed. I cannot for the life of me get one of them secure erased. I've tried in RAID mode, AHCI mode.. nothing works - always says drive is "frozen" and fails. The USB/CD boot things are absolutely worthless - on two different computers. I get jibberish on the screen with both a boot CD or USB. I have no freaking way to secure erase these things. I never had to deal with this $hit with any of my 30+ OCZ drives. ARGH.

Chispy - what method did you use to secure erase your drives? Sucks they both bombed like that - something's fishy. How'd you hose TWO drives? Tell us exactly what you did plz.

[DooRules]

Usually you just hot plug a frozen drive to see it to SE it, I take it that did not work this time.

[Brahmzy]

No amount of hot plugging (either power or data or both or letting drive sit unplugged etc.) worked.

The Samsung secure erase didn't work for me ether so i just used the same program I've been using for years Parted Magic, Also when i went to secure erase them i got a popup saying that these SSDs support advance secure erase would you like to run this instead i hit OK did its normal erase then i set my raid array back up installed windows and here i am.

[DooRules]

It's my understanding you do not want to be using the advanced SE, it may blow away parts of the drive needed for operation. I could be wrong but I just stick with the standard SE.

That is correct. It is not recommended to use the "Enhanced" Secure Erase option.
By the way: >Here< is a description about how to do a Secure Erase of an SSD by using the tool Parted Magic.
