Hello Bill Clarke here, I read the last statment re par corrupted files but I couldn't find the first question outlining the problem. The reason I am interested is because I use PAR and I just lost a whole bunch of files. It started when I transferd a series of tga's that had been renderd with ALPHA channel turned on, at first I thouht this might be the problem but after reading your replies, I am thinking otherwise. I also have the 2217A drive and if there are problems please let me know Thanks Bill C.

>> renderd with ALPHA channel turned on << You may not have not allocated enough memory to the PAR buffer. When you use files that contain alpha, the file size is too big, so you have to adjust the buffer by loading pardrv like this: C:\DPS_PAR\PARDRV /B:1500 See page 109 in your manual for details. I don't think you can recover the alpha from these files once saved to the PAR since they are first converted to JPEG by the internal hardware. If you need the alpha, use Alpha Split in the Render/Options dialog. As for your 2217a, I think that all of them suffer from generating excessive heat. However, if your system is sufficiently ventilated, you may never experience a problem. My 2217a was tightly boxed in and no air could circulate around it. I received my replacement drive ($50 overnight option) which is now working fine. I removed my 5.25" floppy to give the 2217a some air, and it does not seem to get so hot now. I may yet get the external PAR case, though, just for the added security. — James — MAP —

James, Thanks for your help. The alpha channel is not necessary for theses ANI's I am more concerned with why the files got corrupted, there was a lot of activity on this subject in the message area last week and I would like more information on those crashes. Bill C.
