SQLBackup Restore I-O Error

I'm getting the following error when trying to restore a multi-sqb backup set:

Restoring database naxosdb_test from "F:\backupdbtest\naxosdb_01.sqb"

Msg 3203, Level 16, State 1, Server NAXOSSQL01, Line 1
Read on 'SQLBACKUP_243207805' failed, status = 995. See the SQL Server error log for more details.
Msg 3013, Level 16, State 1, Server NAXOSSQL01, Line 1
RESTORE DATABASE is terminating abnormally.

There are ten sqb files: naxosdb_01.sqb - naxosdb_10.sqb

I restored on a different server using the exact same sqb files. I even physically connected the usb disk containing the files to the new server as I thought the error was because I was restoring across the network.
But I got the same error.

The SQL error log just says: Backupmedium::ReportIOError:Read failure on backup device 'SQLBACKUP_75296381'.

Any ideas?[/b]

    What happens when you run RESTORE HEADERONLY ... from each of the ten files e.g.

    sqlbackup '-sql "RESTORE HEADERONLY FROM DISK = [F:\backupdbtest\naxosdb_01.sqb]" '

    sqlbackup '-sql "RESTORE HEADERONLY FROM DISK = [F:\backupdbtest\naxosdb_02.sqb]" '

    ...

    Hi Peter - thanks for replying.

    I get Error 530: File does not exist: F:\backupdbtest\naxosdb_01.sqb
    when I try the HEADERONLY option.

    The disk I'm using for the .sqb files is a cheap USB 400gb one formatted as FAT32. (samsung HD400LD). It is unable to handle large files (eg 15gb) as I cannot copy such files to it. I guess this is a FAT32 limit.

    However, my sqb files are 2gb each and have already been used to restore successfully on a different server yesterday.
    The 'good' server is Win Server 2000 SP3
    The 'bad' server is Win Server 2003 SP1

    I'm thinking of formatting the disk as NTFS and starting again.
    What do you think?

    Can SQL Backup work with the drive at all? If you were to create a backup file to that disk (using SQL Server and SQL Backup), does it work?

    Yes - I've just done a Redgate backup of a 9gb database to the disk. Then deleted the database and restored from the .sqb file on the disk.
    All OK.

    I've just checked and the sqlbackupC.exe version are different on the backup server to that on the restore server.

    Version 4 on backup server. Version 3.2 on restore server.

    So, is it not backwards compatible?

    Yes, it is backwards compatible, in that version 4 can restore version 3 backups. What you are doing is the opposite of this, which isn't supported.

    Yes I see.
    I have upgraded to v4.6 and re-activated and it's now working.
    Thanks for your help. :D
