Well, I never use hard drives or CF Cards larger than 1 GB. In fact, I usually use 512 MB or smaller. Because of this, I have NEVER had any problems with any of my 5 Amiga 2000 computers. They work perfectly, because I do not allow my ego to get in the way. So, can I remove the DOM and just use HDTools to prep and format my drives? Normally, on SCSI hard drives, I type in and save the parameters, low level format the drive, partition the drive, and then check the drive for errors. Then I reboot the Amiga and do the high level format. I have done all of this on the IDE drives as well, except for the low level formatting. That is what I am unsure of. Because, on the PC, you never low level format IDE hard drives. But, on the Amiga you type in and save the drive parameters onto the boot sector of the hard drive. This is the reason why the low level format starts at sector 2, not sector 1. In fact, after you type in the drive parameters and save them to the boot sector of the hard drive, HDTools will not allow access to sector 1 when formatting and partitioning the drive. Anyway, I thank you so much for your help. I am recording a series of videos about the 20TH Anniversary Buddha IDE controller, and then I will post those videos on my YouTube channel: Hans Campbell. So, I am asking these question to make sure that I have the correct information. You have a great product, so, I am promoting it.
