Cause

This error message appears while saving a voucher or recording transactions, in a multi-user environment, due to any one of the following reasons:

● A faulty or broken cable especially for an external USB or Fire wire enclosure can generate this error. It could be due to a long cable that is hooked up through a hub that is not up to the required specifications.

● You may be using a 40-pin cable for the UDMA drive when the drive actually requires an 80-pin cable.

● Mechanical failures of drives.

● Access shared data in an unstable network environment with Windows XP operating system. Due to intermittent network failure, writing to shared data files fails, which can lead to this error.

Due to above reasons Tally.ERP 9 data may get corrupted and it has to be rewritten.

Solution

1. Change the faulty broken cable or connect the cable to the Hub with required specifications.

2. Check and replace the UDMA drive cable, if required.

3. Replace the required drive.

4. Reconfigure network for better stability.

Note: This scenario will appear only if you have Windows XP Operating system. It is suggested to migrate the operating system to Windows Vista or Windows 7 and above that has improved file sharing protocol, which take care of intermittent network failures. These prevent delayed write failures causing data corruption and crashes.
