xrbrevin #1 Posted July 5, 2020 Hi, I recently obtained a damaged LDW Super 2000 disk drive. I mended a few cosmetic issues and yesterday I managed to get a power supply to work with it. It passes the in-built self test and proceeds to spin the disk, seek track zero then it rests at track 39 - as it should. However, as you can see by the pics and vid below, the part of the read/write head assembly that applies spring pressure to the disk/head is missing. as a result i get the 'slow beep' boot error. The drive uses a 'Roctec' mechanism which i believe were only used in this drive and the california access CA2001 drives. both of these are quite rare and internet info is very limited. If anyone has one of these mechs, would you mind uploading some images of the head parts? to make things a bit more tricky, there is a metal plate over the head! fortunately, i have a 3d printer which could produce what i need. Thanks in advance! MVI_2082.MOV Quote Share this post Link to post Share on other sites

_The Doctor__ #3 Posted July 9, 2020 almost but the rabbits fur pad must be level at head contact.. the current angle is over pressure on one side and under pressure on the other... 1 Quote Share this post Link to post Share on other sites
xrbrevin #4 Posted July 10, 2020 yes i can regulate this with a grub screw as per the Rana drive design. through the end of the lifting boom to make contact with the metal rail i could have positioned the felt pad better, i will do so with the next prototype Quote Share this post Link to post Share on other sites
