Re: Prefetch loads multiple partitions of the same disk at the same time
Well, I agree that's the current situation, but I think primocache should never prefetch from two volumes of the same disk regardless if it's the same cache task or different. The whole idea of prefetch is to make things faster and it's not faster when two threads read from the same disk for 10 minu...

Prefetch loads multiple partitions of the same disk at the same time
Hi,
I noticed that prefetch is running in all cache tasks for multiple partitions of the same disk. That shouldn't be happening because partitions are spread over the whole disk and the head will seek a lot. Prefetch should read data from one physical disk at a time.
Noticed on v2.5

Re: Freeze problems when using primocache
I want to get back to the freeze problem. I made some tests. While for SSD it's nto a problem, most flash drives can't read and write at the same time very well. I added a USB3.0 flash drive to OS drive cache and I tested it's read speed while primo cache was writing to L2 (see read-07-September-201...

Apply changes behavior
Hi, Changing settings in primocache is a bit annoying. Can you remove confirmation dialogs for settings that do not reset the cache. Also remove success messages "settings are applied" - you can replace it with dialog box "applying settings" which can disappear after settings are...

I would like to see "what's new" with each version. I can't find it on the site.

Re: Freeze problems when using primocache
The last freeze I had was very bad and I'm sure biggest part was the flash drive. Some flash drives go crazy when you read and write at the same time. The problem occurred after resume from hibernate. Initially it worked fine - it was reading a lot from disk, half of it from cache. Then I started a ...

Re: WinAPI - Direct disk access
My idea was to preload certain sectors. Maybe you can make primocache FS aware and allow the user to choose to pre-load certain fails/regions of disk (FAT, $MFT, others) and exclude others (movies)

WinAPI - Direct disk access
Hi, I have a question that's a bit off-topic. I was playing with direct disk access: HANDLE hDevice; DWORD br; buffer = (char*)malloc (32768); hDevice = CreateFile( devicename, GENERIC_READ, // |GENERIC_WRITE FILE_SHARE_READ | FILE_SHARE_WRITE, NULL, // lpSecurityAttributes OPEN_EXISTING, FILE_FLAG_...
