Hello everyone! I'm new here, so excuse me if this post looks badly formatted and let me know.
Anyways, if you saw my profile on here, I collect old hard disks (<200MB usually). I've recently come into possession of a Cogito CG912 10MB disk (Pictures below).
It's quite the interesting drive (see pictures I took of the inside - I've never seen a disk with a linear stepper motor at an angle like that!), I must say.
However, when I try to format it with anything at all, the software usually gives me 1701(04) or 1701(20).
1701 is a general controller failure
1701(04) means the controller couldn't find the sector
1701(20) means the drive stopped responding
I'm sure you already knew above, but I felt I should mention it for clarity.
It seems the disk is either made from bad sectors or I'm doing something wrong here.
Here's a recreation of what I did:
I'm using a DTC 5150XL controller card with SpeedStor 6.0.3 under a DOS 3.31 floppy diskette. The computer (an ACS Pentium-S 133MHz with 16MB of RAM and an S3 ViRGE video card) has formatted dozens of drives successfully in the past (Managed to get 4MB out of a Kalok Octagon KL320 that had not once been parked since it was new), despite having some issues (Many games crash the system. Not sure why.), such as the diskette drive indicator being perpetually on.
The drive is mechanically sound, since it spins up and has passed every seek test I threw at it. The drive seems unable to read / write any information, however, and some programs see the disk wrong (SpeedStor always sees it as 153C 4H 17S and HDAT sees it as 615C 4H 17S). It still seems to work, since I can park the heads and when the disk is powered on again it will draw them back to track 0.
Should I give up and simply put the disk in the stack that don't work? Should I try a different computer? Is the controller to blame? I have a few other controllers but not many other computers I can use. If anyone can find the manuals for the controllers (I'll give information as requested), that'd be a great help.
Thank's for reading my absurdly long post, and hopefully someone out there can help me.
Note: These pictures were taken about an hour before posting this, and the internal pictures were taken a few seconds after disassembly. The drive spent maybe 45 seconds unsealed in total. The problem occurred before the drive was disassembled.
