Hi, I have SC installed on a separate partition.

I've got MSG in LOG "The Chartbook file is not a valid Chartbook. File: T:\SierraCha.." (x6 chartbooks) after restarting.

I think it's because the disk volume got full.

Please advise if I can recover my chart-books. I've shut down SC and will await your advice.

Thanks so much.

Hmm, this is very strange. I have tried to open backup chartbooks. Five opened successfully but the sixth didn't. After opening the log I see "not enough room on the disk" messages streaming in the log. This is very weird as I made 2GB free only 10 mins ago.

I will investigate.

How much free space do you have on the drive? When you delete files in Windows, make sure to also clear the recycle bin.

Up and running now after doing some drivers troubleshooting and a big virus scan on my computer.

I think it was something to do with (1) Hard Disk being full, and, (2) that because I have Write Caching set to true on this drive within Device Manager... Windows "helpfully" transparently cached various entire SCID files to RAM at the time I originally ran out of HD space, and then later when I had already made some free space, flushed them back to disk as I was opening the chart backup files.

Everything seems ok now. I have over 4GB free (for) now and this drive is just used for trading data.

Our suggestion would be to get a bigger drive. As it is generally recommended to have at least 10 to 15% free space on a drive to avoid performance degradation and serious data issues.
