I have a Vista machine that uses a network share from an XP Pro system
running thru a 1G Netgear switch.
I am having some sort of I/O errors reading and possibly writing files
from/to a network share that results in validation and checksum errors.
However I copied a large 26G file to the network share, and the file
checksumed fine on the machine that owns the share. I think the error
happens only when reading from the XP share.
In particular, Acronis TI cannot validate a large 26G backup file created on
the network share however if I backup locally and then copy the file to the
network share then the XP machine can validate the file.
MD5 also checksumed the file copy just fine running on the machine that owns
the share matching the original but MD5 repeatedly gets different checksums
against the network share from the origin machine.
So it seems that file copy to the share works OK but Acronis TI and the MD5
programs get errors reading from the share.
I get no OS or event log complaints and I have extensively run memtest86 and
chkdsk against the machines and all the drives with no issues whatsoever.
Has anyone else seen problems like this?
Anyone have suggestions on determining if it is the gear or MSFT software?
Odd that file copy of the 26G file works fine in both directions (to the
share and back again) and still verifies and checksums the same but reading
the file from the share appparently gets errors in data that are not
detected by the OS and so fails to checksum.
*** Is there anyway to turn checksums on for the data packets at either the
lower or upper layers of the IP stack or SMB protocol so the block is resent
if checksum is bad???
*** Would somehow using IPV6 between the machines be possible or help?
Thanks,
Dave
