Sql 6.5: Error : 605, Severity: 21, State: 1

I have a big problem with a SQL 6.5 (no SP) running
in a production environment on NT 3.51 SP 4 since
2,5 years.

Suddenly Friday at 99/10/01 14:17:38.93 we started
having problems and we could'nt connect to the
DB from our client server application written in VB4.

We rebooted the server and we had other errors at
99/10/01 16:15:40.96.

The error code is 605-21-1 and it seems like the main
table (FILMS) of our db (VISPO) has phisical allocation
problems.

here is en extract from the SQLServer error log
of the first problem:

99/10/01 14:17:38.93 kernel udread: Operating system error 23(Data error (cyclic redundancy check)) on device 'E:MSSQLDATAvispodat.DAT' (virtpage 0x05000f35).
99/10/01 14:17:43.62 spid13 Buffer 9531a0 from database 'vispo' has page number -1 in the page header and page number 3893 in the buffer header
99/10/01 14:17:43.69 kernel mirrorproc: i/o error on primary device 'E:MSSQLDATAvispodat.DAT'


And here is what we had at 16:15

99/10/01 16:15:40.96 spid11 Getpage: bstat=0x1008/0, sstat=0x80010130, disk

99/10/01 16:15:40.98 spid11 Attempt to fetch logical page 3892 in database 'vispo' belongs to object '-1', not to object 'FILMS'.

We are thinking about restoring the BackUp of the previous night that should be OK,
but I would like what we can try to do in order to have the
db working properly.

Even if the restore would be fine, maybe we are starting
to have problems on the disk subsystems?

What can we check, something like scandisk in DOS?


I attach here in ZIP format the 2 log files and plese ignore the MAPI errors
that are "normal", we just don't care.
I don't know if it's possible to attach files to a newsgroup or a discussion
group but I will try

Any help would be appreciated.

Thanks in advance.
