After creating cache using Max Velo SSD, system fail at startup, showing blue screen with message " system thread exception not handled" "Failure Item: MaxVeloSSD.sys". Keep repeated reboot with this error can't get into windows. Please help

Later I go into command prompt and rename the maxvelossd.sys and I can go into windows but my cached Drive in HDD "Drive E" disappear. Please help so that I can restore my PC into normal, i.e. back to the state before applying maxvelossd cache. Thank you.

Today I uninstalled the maxveloSSD, the problem still exist. I found in the device manager there is a device " partition" with exclamation mark. I remove this device in the device manager and the problem is resolved. My E drive appears again and the PC seems back to normal. Though my PC returns to normal it is a bad experience in using MaxveloSSD.

Please excuse the delayed response. Investigating issues with scheduled Win10 Backup is on the todo list. Will come back if I know more.

Topic: Hardware RAID 0 problem
We have some hardware arrays too and keep them running with Velossd and MaxVeloSSD for some time before your post. Until now we have no issues. However, to be honest we have not yet built a 3 * 10 TB RAID 0. We might build one in the near future. Sorry for the delayed response. I´ll be back when I know more.

Topic: shutdown after add VeloSSD
The sw will start to reboot when the boot volume has been assigned a cache.
Otherwise not, if a cache was added to a data volume it will not reboot.
The data volume will be visible in the drive info window.

After I installed the caches for my 4 volumes with standard cache sizes (8 GB per volume), I wanted to decrease the sizes of 3 volumes from 8 GB to 4 GB.

After changing the sizes and started a system reboot of the PC I got a blue screen before the PC shuted down.

After restarting the PC I noticed in the win explorer 2 of the volumes were not listed. This 2 volumes were listed in the disk management of win10, but they did not have volume letters. When I tried to re-assign volume letters, I got error messages saying this was not possible.

After a while I realised in the device manager there were to volumes shown as not installed by the system - after trying to activate them without success I uninstalled them in the device manager and rebooted the PC.

--> After Win10 became active again all the 4 volumes were OK, but the ram caches of the 2 lost volumes did not change to 4 GB!

--> I had to un-install VeloRAM completely from the system, restart the computer and install again VeloRAM and add again the caches to the 4 volumes with the desired values.

--> This happened 4 days ago.

Again, I wanted to change ram caches of 2 volumes yesterday --> same problems (1 volume went lost!) --> deleted in device manager and reboot --> cache not changed --> un-installed VeloRAM again --> after new installation of VeleRAM, created ram caches for all 4 volumes.

==> changing ram caches does not work on running VeloRAM! It has to be completed un-unstalled first...

Creating an instant system image of all drives is going well... But the "standard Win10" scheduled backup is not possible!

Hardware RAID 0 problem

I agree with everything you said. Raid 0 is most risky. One drive failure and it's toast. However, to be frank, in my 20+ years of RAID experience, I've had more data loss with parity failures than a drive failing. I've found that redundant RAID 0 arrangements a better than a RAID 5/6. RAID 10 is good to (pretty much the same thing).

I also agree, this type of cache shouldn't cause a failure, which is why I invested in it. The cache is just a copy of the actual data. This is why I was SO surprised with the failure. It's been running flawlessly on my other server, which is using a LSI RAID controller (Raid 5/6). Anyway, for the RAID 0, I simply reformatted the drive, NOT using the cache and it's back to it's usual performance. No issues. It could have been just a fluke. (A coincidence, but an extremely unlikely coincidence). Once I get all the data replicated again, running efficiently with redundancy, I'll try again.

There was a time where the software locked up and became unresponsive. it was about the same time as this failure. There is no way to know cause vs effect.

Could the caching be overloading the RAID 0? I realize you'd be reluctant to share, but are there any other cases where there was issues with RAID 0? I'm fine if there is/was. I just need to know the limitations. I'm guessing not. I don't see how it would matter. In fact, I would think RAID 0 would handle caching better than a parity array.

This was ** A LOT ** of data for a failure. As I said, I had redundancies, but it took a lot of time to recover. I've never had any issues with these drives EVER, until 2 days after installing the cache.


Can you give me more detail on the different performance profiles. Clearly, since you have the different options, the risks vary. Could that be my issue? Should I stick with a lower 'conservative' performance profile? Beyond your standard documentation, do you have any standards for which to use and when? I'm sorry if I'm not being specific. It's only because I don't know the right questions to ask. Thanks for your help. Don't worry, I'll continue to use your software.

Oh, BTW, these drives are less than 2 months old. Used enough to know they aren't defective, but not enough to wear them out. I can't believe it's the drives. I could see, however, that it could be the RAID software. Intel Rapid Storage is 'software raid'. The software could have conflicted with the caching software somehow??


The Rapid Storage software has SMART monitoring built in. Any SMART events would have immediately registered, which did not happen. None of the drives failed.The array formatting simply went from readable status to unreadable, requiring a reformat to become usable. By observable indications, it's like the boot sector was corrupted. (I have a feeling, if I didn't have redundancies and this data was invaluable, I could have had the array rebuilt. It was easier to just re-copy from the replicated source)

Several terabytes of data takes quite a while to recover and then sync up with the replication. Once this is finished, I'll try again. I guess we'll see.

Topic: Hardware RAID 0 problem
I am sorry for the error on your system.Certainly there are starting points that I would like to mention in connection. First let me make it clear, however, that our software does not make any use of proprietary specifics. but completely generically accessing it. It is therefore not possible that a crash on your Intel Raid Controller may have been caused by our software.Furthermore, it is generally known that RAID0 is the most error-prone mode in which an array will fail completely when a disk fails. It is also generally not recommended to use Raid0 if you do not have at least 1 complete backup to reserve. ( sorry had to type this in german , thanks to google translate )

I would double check the harddisks with SMART tools and create at least one complete backup. Great would be new harddisks for the system with Cache. And use the old one as a second safe backup. And to be safer on the long run, upgrade to a higher raid level.
