That is very common with the disks formatted using some ST programs (as Fastcopy Pro, for example), with more than 9 sectors/track.

Usually, in that case one sector is not easily read.

In the Surface graphs, the "circles" are not closed. In the Tables of sectors, this sector will be marked as red. It should be " = SORRY, THIS SECTOR CANNOT BE READ FROM FLOPPY DISK BY ST RECOVER.

ST Recover will replace its data by a repetitive sentence, in order to help you to detect it with ease.

Red: cannot be read at all (maybe physically damaged), even after several tries.

What mean the colors in the Tables of sectors ? Try again to read the disk, it should work after a few tries. Maybe the very first sector, the boot sector, is not read correctly.

The software says " No disk in drive" but there is a disk ! Anyway many technicals have changed since the old time of the floppy disks, MFM hopefully disappeared, we have a constant surface/sector, there are more than two levels per information, etc. On cdroms, the surface/sector is constant but the rotation speed change. On modern hard disks, the surface of the sectors is (almost) constant, that allows to gain 50% sectors more but needs a (bit) more complex processing. That explains why the first sectors (the track 0 is the outer track) are considered more secure than the last sectors (the inner track is the last one) : more magnetic surface for the same amount of data. It is interesting to notice that the outer sectors occupy more physical space than the inner sectors (in reality they are about twice bigger). So it represents the real disposition of the sectors on the disk (except for the diameter of the inner circles, which is relatively bigger in reality). This representation is computed from a timing analysis during sectors reading. Sectors are read counterclockwise from the mark. The line on the right represent the location of the virtual synchronization mark on the disk. If your disk seems to be damaged, or just for curiosity, click on "Analyze surface" to see a geographic analysis of the sectors on the disk.Įach "split circle" represents a Track (the color is alternated from one track to the next one), and each part of this circle represents a Sector, which is a packet of 512 bytes (in general).

Select the location and the name of the image file to be created.

Click on "Read disk and save image file".

If necessary, select the right drive (A or B).

If you have an internal floppy drive, install this external free software.

With a USB disk drive, ST Recover cannot read special formats, because of the interface limitations.īut a USB drive can read ordinary formats as 360 or 720 Kb. On your real PC, a not-USB floppy disk drive is needed for special formats External (USB) floppy drive

The black line on the right is the virtual synchronization mark. This is the surface of one face of a real 800 Kb disk. You can see the geography of sectors on your disk:

ST Recover takes advantage of a free driver that can read these special formats.Īn effort has been done to recover desynchronized or damaged disks. Unfortunately, these formats are very common in the world of the ST. Normally, Windows cannot read special formats (as 800 or 900 KB) because of limitations of its floppy driver. Should be compatible on Windows 8,7,Vista,XP,2000,ME,98,95 and later. Internal is better, but external can be used with limitations. ST disk image file Required configuration Then the image files can be read in ST emulators as WinSTon or Steem.

ST Recover can read Atari ST floppy disks on a PC under Windows, including special formats as 800 or 900 KB and damaged or desynchronized disks, and produces standard.
