I don't know. Recall that it took Phillips about 40 years to catch on (invented in the 1940s, not really dominant until the 1980s if memory serves me right). Torx should catch on by the middle of the century...

Square drive (eg: Canadian "Robertson") are almost as good. I drove several hundred 3" deck screws through flooring yesterday - once put on the driver, they stayed put on the driver and could be started and driven without touching the screw. No cam-out either. I still think they should make the manufacture and sale of slotted and phillips screws a capital offence. -- Chris Lewis, Una confibula non set est It's not just anyone who gets a Starship Cruiser class named after them.

The best way to ensure that you can copy over the good partitions is to _not_ open the drive first. The safest way is to image copy the whole drive to a new drive. Put the old drive in a safe place, and try to repair the new drive's directory structure. Preferably doing a backup of the image you copied to the new drive before you diddle it, so you can start over _without_ touching the old drive. The clicking is most likely retries (ie: gouged media, weak magnetics). You _can't_ fix that. You're unlikely to be able to repair even obvious mechanical faults either. -- Chris Lewis, Una confibula non set est It's not just anyone who gets a Starship Cruiser class named after them.
From: gypsy3001 on 16 Jan 2006 17:18 Thank you for identifing this screw as the Security Torx Plus. It does have a pin in the middle to warrant "Security". Now I just need to figure out where to get one. I want to thank everyone for responding. In one day, there are 50 messages to help me identify a strange screw, offer help tips to unscrew it, and an explanation of clean room. Newsgroup and all you helpful people are awesome! I also read a lot of questions on what I am planning on doing, and lots of warnings on taking hard disc apart and killing it. I would like to answer these questions and clarify my position. First, you can read about what I am planning on doing here: http://www.gearhack.com/Forums/DisplayComments.php?file=Tool/Screwdriver_for_5-Point_Star_Screw.html As you can see, I am not talking about taking the internal hard drive apart (although I have done that in the past). But rather, I want to take the external case apart. Chieh -- Camera Hacker - http://www.CameraHacker.com/

No, I was going to open the drive last, after all my software solutions failed. I'm sorry I didn't mention that. >The safest way is to image copy the whole drive to a new drive.

You're unlikely to be able to repair even obvious It only clicks if I try to access the bad partition, and even then not always . I can read the good partitions, but I'm told the clicking will get worse. >mechanical faults either. Remove NOPSAM to email me. Please let me know if you have posted also. |
