Here is the description of the errors and some work-arounds. All errors will be fixed in the next release, comming in about 3 weeks. Once again: I hope, you will understand my english. Feel free to reedit this text. 1) Qcopy and Qformat will fail on some rare known BIOS. They will work on common known BIOS (AMI, Phoenix, Compaq, etc.). 2) There is a problem with the automatic-detection of well formatted disks. In some cases Qcopy thinks that the disk is properly formatted; but it isn't. This applies to disks, that were previously formatted with any nonstandard tool or in a different format. For example: - pcbackup with maximal compression - formatting a HD-disk to 360 Kb and using qcopy with the 1.2Mb option The error applies only to the unused potion of the disk. The data potion is ok, if you use Qcopy with 'Verify on'. If Qcopy encounters an error while copying, it does a format of the bad track. But Qcopy does no verify on the unused potion. You can see this behaviour on the screen. While copying the data, you see WRT, FRM, VER for each datasector; but you will see no FRM for the unused potion. The work-around is using Qcopy with the 'f' option; but read the next point first. 3) There is a misbehaviour of 'Qcopy f'. This option will be ignored; if you are using 'f' as the only option on the command-line. The work-around is to apply all needed options on the command-line. 'Qcopy a a 1200 f' gives the expected result. Some good news: Qcopy seems to work with DOS 5.00. There will be a special version for MS-Windows - running in the background - at the end of the year.
