Write to file error   07 May 2016, 01:09

Hi,

SoftPerfect RAM Disk is great, but I encounter a problem. After last time windows update, some software can't write to RAM Disk. (1.jpg)
I had CHKDSK RAM Disk and do not find any problem. I try to re-install windows-x64 again and found some signs.

(1) Before windows update, it will not has this problem. Maybe one of 2016/April windows update cause this issue.
(2) If you don't use "Hard disk Emulation", you will not encounter this problem.

Please help to check this problem.
Thanks.

Is that a volatile RAM Disk or a persistent one with a on-disk image attached to it?

It's volatile RAM Disk.

I'm afraid that's too hard to reproduce, sorry.

Basically what you are saying is this Windows update seemingly broke something that FlashGet can't write to the RAM Disk and only when Hard Disk emulation is on. It could be virtually anything and before spending hours trying to reproduce and debug the issue, let's wait and see if anyone else encounters a similar issue.

Update information.
After I remove these windows update, the issue was gone.
KB3092627
KB3102429
KB3107998
KB3118401
KB3121255
KB3123862
KB3126446
KB3133977
KB3137061
KB3138378
KB3138901
KB3139923
KB3140245

I update one by one, found KB3137061 will cause "Write to file error" issue.
Not only FlashGet but also Chrome. If you save chrome profile to RAM Disk, history and some Extensions will abnormal.
Can you help me to check it?
Thanks.

Apparently it has something to do with the SCSI synchronize cache command sent down to the RAM Disk's driver. What OS is that on?

It may take us a while to figure out what's happening there. I suggest you don't install this update in the meantime or don't use the Hard Disk Emulation feature.

My OS is Windows 7 Ultimate x64.
Thanks.

I have tested the software with a RAM disk with HDD emulation enabled on a Windows 7 x64 system with KB3137061 installed. Unfortunately I wasn't able to reproduce this bug as all reading and writing to the disk completed successfully.

It might be a conflict with some other third-party software or drivers. At this stage there is nothing we can do about it, so I still recommend not to install KB3137061 or not to use the HDD emulation mode.

Sometimes you can get the answer faster if you try the forum search and/or have a look at the software user manual to see if your question has already been answered.
