View Full Version : Alignment disks?

February 20th, 2014, 05:23 PM
I'm looking to buy 5.25" floppy alignment diskettes. Accurite has drive probe for $199 this has 3.5 and 5.25 but seems to be low density only (720k and 360k) if I want to align 1.2m floppies I'd have to get the drive probe advanced for $999. So, I thought I'd just get 2 analog alignment disks and use my o-scope to do it. Not having experience doing this before, I see 3 different 5.25" 1.2m alignment disks and 3 for 360k drives. So, which do I need? I sent accurite an email but got no response.. If anyone has used these can you point me in the right direction?

I got a response from Accurite, in case anyone else needs this info I've added it here.
For 1.2m drives, you need just the 206-34 AAD. The 206-43 and 206-44 are for special testing that some drive manufacturers recommend. For 360k drives you need the 224-2A AAD disk.

Note also, that DriveProbe uses a digital alignment method, where only a PC is necessary. The AADs require an oscilloscope.

And to expand on what Chuck said they no longer have or produce the alignment disk for DriveProbe and HD drives so your only option is the AAD unless you can find a used one.
