My A3000 guru'd while trying to save an ILBM file with XLispStat running in the background. The drive which it was saving to now reports a "Volume Misc has a checksum error on disk block 87611" which comes up when trying to access the partition either while reading or deleting the offending file. It also comes up when accessing the drive on boot up. What can I do?? I tried HDToolBox and checked for Errors on Disk. There are none reported. I do not want to reformat the drive since I am out of floppy disks to store the data on (besides the partition is 50 meg). Help!! There are several very important files on the partition. How can I fix the problem? Disksalv does not seem likely. I also thought about using a disk utility such as NewZap or DiskZap. These do not seem compatible with a hard drive. NewZap references only by file and DiskZap seems to have no way to reference disk blocks by decimal number. Besides, I couldn't figure out what to do with the file when I get it on NewZap. Does someone have any suggestions, or could you direct me to any utilities which may be able to repair files or blocks with damaged checksums and validate the partition? Also, Filemaster will not write to the disk. Anything I do comes up with "Volume Misc not validated". Is there anything I can do? Please reply email ASAP since I have to get this partition working by tomorrow. Thanks very much, Veenu

Most suggested that I buy QuarterBack Tools. I tried a PD utility called FixDisk which would not work with my hard disk partitions. Finally I just copied the important files and formatted the partition. I got one good suggestion that I find the hash table for the file and zero it or something. I am fairly useless at navigating my way around the AmigaDOS file system. However, if I could get to the offending block I could just as well fix the checksum using DiskZap. Unfortunately, DiskZap did not really know what to do with a hard drive. I would like to find a way to disconnect a file from a directory if this ever happens again - maybe a manual way to 'delete' the file and validate the partition. Any ideas ? Anyway, post followups to comp.sys.amiga.misc and do not send me mail! Thanks very much, Veenu
