- You have three choices.
- 1) Align your drive after a lot of R-ingTFM, with an oscilloscope. It is a
- delicate and time consuming process, but can be done.
- 2) Buy a special diskette that virtually turns your PC into an oscilloscope
- for the purpose of drive realignment. This special test diskette plus the
- testing software will probably run you a low(?) three figure sum.
- 3) Replace the drive. At around $60 for a new drive, how much aggravation is
- it worth? It is certainly NOT worth paying a professional to do #1.
-
- Bottom line; if you want a working drive, do #3. If you are more interested
- in learning how drives are aligned, use #1 or #2. If you choose #3, you can
- still _also_ choose #2 as a diagnostic tool for ongoing use.
