Hi,

You can try these follwing options:
1. dbcc checkstorage (if not run already)
dbcc checkverify (to classify soft and hard faults)
run sp_dbcc_summaryreport for that database
sp_dbcc_faultreport
sp_dbcc_help_fault
This will help you to fix the problem

2. If the above option dosen't fix the issue, you can re-create the
database ( make sure you follow the segmap of existing devices).

3. If these dosen't help you, then Sybase support is the best option .

Thanks,
