Hi Dan, I've experienced the same kind of problem with caddy. After investigating the problem, I'm quite sure the problem is heat. The fan mounted at the back of the caddy is not prowerful enough, certainly if you are using 7200rpm drives. I'm still using caddy on machines running sometimes 24/7 without any problem doing this : - try to use metallic caddy. Plastic ones act as a hoven. - If you are still using plastic ones don't put the cover and place on the bay above the drive a fan (I found one from coolmaster, it has the size of a cdrom and fits in a standard bay) that extract the heat out of the case. - You can also find flat fan that can be screwed on top of the hard disk, the metalic frame acting as a heatsink. Remember : in computers, heat is one of your worst ennemy. Hope this will help you Christian Vicente IS Officer Fortis Bank - End User Automation/1258 Tel :+32 (0)2 228.4457 E-mail : christian.vicenteat_private transmission index : 1GA4R > -----Original Message----- > From: daniel heinonen [SMTP:d.heinonenat_private] > Sent: Monday, July 16, 2001 12:59 AM > To: forensicsat_private > Subject: Re: use of removable hard drive caddies in forensics lab > > Hi Pat, > > I own 2 caddy and my old flat mates owned 6 caddy between them.
