CF to IDE adapter

[Thomas]

Luckily you installed a very old version of SFS which still supports HD_SCSICMD with access to up to 7.8 GB without a patch to the underlying IDE driver (scsi.device).

Beware to upgrade to the latest version. It does no longer use HD_SCSICMD and all your big partitions will be broken.

Did I? I downloaded from here which I assume is the latest version. Please correct me if I'm wrong.

John Hendrikx stopped developing SFS long ago and gave the project to Joerg Strohmayer. The latest versions are available here: http://strohmayer.org/sfs/

Or on Aminet: http://aminet.net/package/disk/misc/SFS

Could you elaborate on this or point me to information on the subject.

Normally AmigaOS can access only the first 4GB of a drive. Not single bit more. If you create partitions outside the first 4GB of a HDD you risk complete data loss.

With HD_SCSICMD you can send SCSI commands to the device and with this method you can theoretically access up to 2 TB (even more if the drive uses more then 512 bytes per sector). In the case of the IDE driver (called scsi.device for funny reasons), the limit is 7.8 GB, even with HD_SCSICMD, because the driver does not allow to use more than that.

While John Hendrikx maintained HD_SCSICMD support in SFS, Joerg Strohmayer removed it completely. So do not upgrade your version of SFS.

To make sure that all your partitions can be accessed safely before writing data to them, you can use Check4GB. http://aminet.net/package/disk/misc/check4gb
