Customers have been complaining a couple of new, very particular concern with the Home windows 11 24H2 replace. This time it impacts Western Digital SSDs, extra particularly homeowners of the SN770 and SN580. The bug has been inflicting crashes and triggering Blue Screens of Demise, and it’s not clear but simply what number of are affected because the 24H2 replace rollout continues.
House owners of Western Digital’s SN770 and SN580 SSDs started noticing the crashes over per week in the past. At first, it wasn’t clear what brought about them, however the widespread denominator was they began after putting in the 24H2 replace. Customers have made numerous makes an attempt to repair the problems, and a short lived workaround has been discovered.
The nitty-gritty particulars
The problem is attributable to the best way the SN770 and SN580 deal with information. These SSDs are DRAM-less. DRAM is Dynamic Random Entry Reminiscence, and it’s used to retailer and shortly retrieve metadata about saved recordsdata. If an SSD lacks DRAM, it means it should depend on an NVMe characteristic, Host Reminiscence Buffer (HMB), the place that metadata is saved in your PC’s predominant reminiscence.
Usually the SSDs ask your PC to allocate 64 MB of HMB to retailer temp information, however with the replace, the SSDs are asking for as much as 200 MB, and sending the system right into a frenzy from which the one doable escape is BSOD.
DRAM-less SSDs are normally inexpensive, funds drives. They’re cheaper to make, and in addition eat much less energy, making them suited to laptops and cellphones. They normally have a smaller kind issue, too, as a result of the DRAM chip will increase the dimensions of the SSD.
Efficiency does take a success for this saving. Accessing reminiscence by way of HMB introduces latency, significantly with learn and write operations. Drives of this sort are additionally vulnerable to extra points as a result of improperly managed HMB may cause, yep, you guessed it, BSODs. And they won’t final as lengthy both; their cells put on out quicker, not benefiting from DRAM’s means to clear previous information and make approach for the brand new (rubbish assortment).

Way back to Sep 10, members of WD’s neighborhood discussion board shared information of the bug. One consumer wrote:
After put in Home windows 11 24h2 I received this in occasion viewer:
The driving force detected a controller error on DeviceRaidPort1.
Blue Display screen ands restart.
WD SN580 2TB. Firmware is up to date to 281040.
WD Dashboard exhibiting Drive Well being 100%.
Any repair?
edit: Since I purchased my laptop 6 months in the past I didn’t have any issues with Home windows 23h2. Right this moment put in 24h2 and after 10-15 restarts I received 4-5 blue screens with the identical error “The driving force detected a controller error on DeviceRaidPort1”.
One other consumer on the identical thread wrote:
hey man i’ve been wanting in all places for information on this. simply received a brand new pre-built laptop with home windows model 24H2. I’ve a WD blue SN 580 2 TB NVME and hold getting blue screens when restarting the laptop or opening sure recordsdata in file explorer. the occasion logs main as much as the blue display in occasion viewer give the identical occasion ID 11 stornvme and volmgr error. You’re saying the primary cause is the brand new home windows replace? wouldn’t it be clever to roll again or have you ever figured something out since your final submit.
Then on 8 October, a WD neighborhood discussion board member posted a possible workaround, apparently bemoaning the dearth of response from Western Digital and Microsoft:
Whereas we nonetheless don’t have any official reply neither from WD or MS, there’s a workaround!
Thanks @nissel! This can create two registry entries. If you wish to take away them once more, delete them by hand or use this: Registry file to take away the HMB coverage entries · GitHub 22. Apparently for some units it is sufficient to simply disable HBM: Home windows Registry disable HMB · GitHub 19.
Does Microsoft deserve the hate?
In fact, no main OS updates are with out concern. Home windows 10’s now-infamous April 2021 KB5001330 replace brought about a slew of crashes, efficiency points, and the long-feared BSODs. There have been set up failures, lacking recordsdata, efficiency drops in video games, system crashes, and extra. So, far the Home windows 11 24H2 bugs aren’t almost as dangerous.
Microsoft and Western Digital are conscious of the difficulty, and patches and firmware updates are possible on their approach. It stays to be seen if extra customers with related SSDs will encounter the identical points.
No matter thrilling bugs are but to return with Home windows 11’s new model, we’ll be right here to let you know about them.
