October 9, 201213 yr Sometimes when I do a file copy to a share, the file is written directly to the share and data disk, bypassing the cache drive. This seems to happen only on fairly small files - say 30 MB or less. The cache drive does spin up, but so does the correct data disk. The cache drive shows the directory where the files should be, but the directory is empty. The data disk then shows the copied file already on the disk. Is there some sort of logic that bypasses the cache drive or moves files immediately on files of a certain size?
October 9, 201213 yr Ehm. No. Cache drive is not used when writing directly to a disk share though, only when writing to a user share. Also when you copy on the server itself (thru console) it is not used.
October 9, 201213 yr Author Man, I swear this is happening! LOL. I must be going crazy. I backed up a file to a share (done this several times to prove I am not crazy), both the cache and the actual physical disk spin up, the file on the physical disk shows the current date and time, the cache disk is empty. This only happens on pretty small files. OK, well, on to better things - just driving me nuts!
October 9, 201213 yr Author If the file exists already on the data disk then the cache is not used. Good to know. So if the file is just an updated/modified version of an existing file it gets written immediately? I did not know that, and maybe I wasn't crazy!
October 11, 201213 yr It would appear that it magically appears in the user share because that's the magic of the cache drive, then later it will actually move the file and the user is none the wiser. However if you check the Disk Share it shouldn't be there until its moved.

See the screenshot (I assume you have this done, but better safe than sorry).
