I recently downloaded TIMEPARK from simtel20 and it seems to work on my PS/2 30-286 as described. But one question hunts me: does TIMEPARK hurt the disk more than it tries to save? I suppose TIMEPARK powers off a hard disk before parking its head. However, the power surge during power-on and off can be hazardous to a disk module. And the unstability of the head during those periods would make the hard disk more vulnerable to scatching. Was there any study on this subject? Any information will be appreciated. Mingqi

Parking only means that the head is moved to a track position which is beyond the area where data is stored. When the head is moved to the park position (usually the last track of the disk), it helps to prevent the loss of data due to power failures, jarring, etc. Since the last track will normally contain no data, if the system hiccups, and the hard disk accidentally writes something, it is written in an area where no data is located. Therefore, no data will be lost (at least in theory).

Does anybody know of any pc software or computer or anything really that can do the following. Lets you digitize some one and then after you have digitized them you can put different hairstyles on their head. Something you are likely to find in a beauty salon. I am looking for something like this not for playing with but for professional reasons. If you can help please drop me a line at: yphotons@athena.mit.edu
