[RASMB] Software Crash

[John Philo]

Irene and all,

The data acquisition software (GUI) is for some reason also VERY VERY
sensitive to disk fragmentation. Keeping your hard disk empty as Mischa
suggested does not necessarily get around that issue---I have seen data
acquisition stop unexpectedly when the disk was 99% empty, and work normally
again after it was defragmented.

I now have my computer set to defragment every night.

The characteristic symptom of the fragmentation issue is that velocity data
acquisition will just stop prematurely, and if you inspect the last few
scans that were recorded you will find that the cells have been permuted
(the data saved in a file name indicating cell X will really be for cell Y).
Very strange indeed!

John

Thank you Mischa!

Now you mention it, when I reloaded the software I just did a test SV run
with some BSA. I set the number of scans to 200 and it worked fine. My
normal way for SV is to set the scans to 999 and stop it when sedimentation
is complete! I'm going to try it your way now :-)

Dear Irene,

Our XLI does the same thing, although usually only if
you program more than 500-600 scans. We've not really
found a way round it, but tend to programm a max no of
500 scans and try to keep the hard drive nice and
empty which seems to help as well...unfortunately not
the ideal solution!

Regards,
Mischa
