text: hmmmmm....i can make a guess as to what happened...the logical extension of the drive has diappeared....populate the hard disk in the device manager properties and see if it's showing it's entire capacity(i.e. e.g. 80 GB) if it's showing the proper volume information then  for the recovery of drive D: there are two things that u can do....1st is use partition magic software..but i've never used it so don't know any more abt it...2nd: u will have to prepare a start up disk and delete all the partitions on the hard disk and again create the primary one and the extension of it (i.e. the D:&#92; drive) u'll lose all data in this process and u'll also have to reinstall the OS....so if partition magic is helpful....use it...\nsorry cannot explain anymore in detail here...(by the way....if the volume information shown in the device manager is correct then no use trying to jack the cables....so don't mess with it..)
