I am trying to restore files on my IBM/AT that were extracted from an IBM/XT using the BACKUP command. The files were all residing in a directory called /merge. There are 16 disks in all. All goes well with disks 1 through 9. When I insert 10, I get the following message: Warning! Diskette is out of sequence Replace diskette or continue if okay Strike any key when ready When I first tried this, I didn't know the disks HAD to be in the same directory as when the BACKUP command was run. Then, it didn't restore anything, but the disks (10-16) were numbered 0: 0; 0< 0= 0> 0? 00. This explains the 'out of sequence' message, but I still need to get around this. When I hit any key to continue (without replacing the diskette), I get the same message again and again. I tried starting the RESTORE command with disk 10. This worked (sort of). Each disk gave me the above 'out of sequence' message but it allowed me to RESTORE each disk. I just didn't RESTORE the one file that overlapped each diskette i.e. I'm still missing 6 files. Am I doing something wrong. Is the BACKUP/RESTORE procedure limited to 9 diskettes? Is there any workaround, or do I need to have them backup'd from two directories (splitting them to less then ten diskettes each)? Any help would be appreciated. Thanks. Jim Jackson mibte!jnj

Suggestions: Do yourself a favor and get Fastback.. Among other things, it's not DOS-specific, it's MUCH faster than DOS, and a super all-around program.

For some reason that I really don't understand, different versions of MS-DOS refuse to admit that a backup disk is really a backup disk. For instance, I once tried to move a backup disk from PC-DOS 2.11 to an AT using PC-DOS 3.10. The result: BACKUP steadfastly refused to admit there was anything on the backup disk at all. No error message indicating wrong version of DOS, just one saying "this is not a backup disk" or something like that. >Suggestions: Do yourself a favor and get Fastback.. > Among other things, it's not DOS-specific, it's > MUCH faster than DOS, and a super all-around program. This is a good suggestion: I too like Fastback. However, it will do you little good in restoring what you have. What I did was rewrite RESTORE. BACKUP prepends a 128 byte record to files that it writes out (I really can't remember the exact method it uses for multiple files but for only one file it does this). You can restore a BACKUP file by stripping that off for each disk in the series. You'll have to do more research than this if you want to create a utility, though. When I had to do it, I was only trying to restore single files that were backed up. They spanned multiple disks. Just writing a fast program to strip off the header on each disk and concatenate the files worked for me; somehow I doubt it's so simple if you have multiple files. Anyone else out there have a better way? Besides walking in the doors of Microsoft and trying to shoot the person who wrote the %^# utility in the first place, that is. >NOTE: Not related in any way to Fifth Generation Systems, Inc.

Especially since they deprotected Fastback! %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Jim Frost * The Madd Hacker | UUCP: ..!harvard!bu-cs!bucsb!madd H H | ARPA: madd@bucsb.bu.edu H-C-C-OH <- heehee +---------+---------------------------------- H H | "We are strangers in a world we never made"
