Micron 5200 firmware bug

Is that Cisco / OEM only

No that 5100 is generic:

When you search on ebay for Micron 5100 SSDs with Cisco labels, usually they have D0MU. But I guess it depends which hardware had them. Server/SAN might be different from networking. I wouldn't know, this is a Mellanox household.

So a 5200 update came from Hetzner.

5300:
12cd559c751fddfdd1b3d35a4c1e983f94c1a583bc8fb1816a1c3e159dfbb0df M5300_D3CN003.bin

5400 is supposed to work with D4MU and D4CN, because hardware takes both:
3293c9b6357540c2c22724e1f97dcdc8d826f06a6b3b20f09c6b6d1d25542ded M5400_D4CN005.bin

Fixes are around a year old, from August/September 2025. For 5300 this worked:

hdparm --please-destroy-my-drive --yes-i-know-what-i-am-doing --fwdownload fw.bin /dev/sdX

If you have a C400 mSATA, word on the street is they can hang after 80+ days of uptime. Apparently Micron made a firmware that detects the hang and then... just reboots the mSATA card.

You might try running /usr/bin/update-smart-drivedb to see if an updated data file might id those unknown attributes.

I already checked smartmontools/drivedb/drivedb.h at main · smartmontools/smartmontools but nothing. Could be super cap / plp cap status like with Samsung, unknown. There is no documentation because Micron still busy counting money in basement.

So where do you get it from ? Last update on Micron Website for the 5100 is from 2021 and last Time I checked it wasn't on the Hetzner NFS Share ...

EffrafaxOfWug · Aug 29, 2026

I was about to ask the same Stephan - saw you'd referenced the D3MU005 for the 5300 series but this is the first I've seen of this new firmware, and note you've also mentioned a D4CN005 for the 5400 series as well, neither of which appear on Micron's regular download page of course... t'internet is also seemingly very quiet about these and their checksums as well, so this would appear to be highly novel information.

hdparm --please-destroy-my-drive --yes-i-know-what-i-am-doing --fwdownload fw.bin /dev/sdX

Thanks for confirming - I've always wanted to try that as opposed to msecli but could never get the courage to risk bricking a drive in the process

And would be available from ..?

(Besides behind a Cisco paywall ideally

SMART attribute 201 according to latest msecli is "Power Holdup Circuit Failures". Micron's bad caps detector. Older firmware will turn SSD read-only, later will show the problem in SMART and supposedly continue. Edit: Might "just" be a software bug: New Validation against CSCwr08802 by dongqiu1 · Pull Request #348 · datacenter/ACI-Pre-Upgrade-Validation-Script
249 is "Write Amplification". 250 is unknown to msecli version 12.03.032026.00. Maybe moved 196, "number of grown bad blocks".

I made a new /etc/smart_drivedb.h:

Code:

Some comments. After upgrade, a few SMART attributes are removed or moved:

Code:

For 5100 there is D0MU078.

If your Micron 5x00 drive goes into read-only mode, try to measure PLP buffer caps (LCR meter). If suspicious, solder new ones. Worth a try at current prices.

Where can get firmware version D3MU005?

All new micron fw's avaible here https://files.hddguru.com/download/Firmware updates/Micron/

EffrafaxOfWug · Aug 31, 2026

I assume they were very recently uploaded by an enterprising soul

5300-d3mu005-d3cn003.zip and 5400-d4cn005.zip both look to contain variants for cisco (presumably CN = Cisco Networking with MU being the more generic Micon) and there's a few strings in the firmwares themselves that look like they reference some cisco-specific bugs, but no specific mention of the 65k hour bug in there that I could see. Time will tell I guess...

Are those FWs capacity dependent?

Tried flashing with msecli and hdparm and both failed on my 3.84 drives.
Ai said it might be for the Ciscos and the general 480 drive only (based on strings).

Ok, maybe its Truenas but I got too far for this to be a likely culprit... and nowadays its only Linux anyway.

Code:

./msecli -F -U ./M5100_D0MU078.bin -n /dev/sdb

Are you sure you want to continue(Y|N):y

Firmware update for /dev/sdb will take a few minutes to complete.

3.84 version is not compatible with 240/480/960/1.92 capacities.

Stephan · Aug 31, 2026

Yes. You need D0MU4xx but afaik not available, and somewhat unlikely to show up. Example:

Code:

[D0MU075]
drive_model=5100ECO,5100PRO,5100MAX
firmware_type=MU
capacity=240,480,960,1920
display_version=D0MU075
[D0MU445]
drive_model=5100ECO,5100PRO
firmware_type=MU
capacity=3840
display_version=D0MU445
[D0MU845]
drive_model=5100ECO
firmware_type=MU
capacity=7680
display_version=D0MU845

I can confirm Hetzner's M5200_D1MU040.bin works on Micron_5200_MTFDDAK960TDN. No SMART changes here.

I thought I also had a bunch of 5100 MAX, but apparently bought a few SM883 3.84TB in 2022 for really cheap instead to diversify.

Flashed a second Micron_5300_MTFDDAK960TDT from D3MU001 to D3MU005. Out of Microns now. Performance imho reasonable for SATA:

Code:

Sequential Read:  518MB/s IOPS=0
Sequential Write: 503MB/s IOPS=0

Sequential Q32T1 Read:  519MB/s IOPS=16
Sequential Q32T1 Write: 509MB/s IOPS=15

512KB Read:  377MB/s IOPS=755
512KB Write: 410MB/s IOPS=821

4KB Read:  29MB/s IOPS=7500
4KB Write: 131MB/s IOPS=33542

4KB Q8T8 Read:  310MB/s IOPS=79416
4KB Q8T8 Write: 330MB/s IOPS=84524

Several in this thread have I think, including me. There doesn't seem to be anything Hetzner-specific about the firmware. The below were done gradually over the course of a few weeks to see if any problems presented themselves, none so far.

I've left one drive above at D1MU830. I've a 3.84TB drive elsewhere that's also received the upgrade, as my oldest it hits its 65k hours son saturday the 5th.
