Running MySQL Distrib 3.23.54, on i32 using Win2000 NTFS. This is where I see the error:

E:\mysql\data\test>myisamchk -O key_buffer=512M -O sort_buffer=512M -O read_buffer=64M -O write_buffer=64M -r -S -a rsecpossqs - recovering (with keycache) MyISAM-table 'rsecpossqs.MYI' Data records: 54822847 myisamchk: warning: Can't change size of indexfile, error: 22 myisamchk: error: 22 for record at pos 4294967232 MyISAM-table 'rsecpossqs' is not fixed because of errors Try fixing it by using the --safe-recover (-o) or the --force (-f) option

And this is about 4 hours after starting the command; right after myisamchk runs through counting up the rows.

The table is the standard size, no adjustments have been made to the AVG_ROW_LENGTH and MAX_ROWS yet. File sizes are:

4,294,967,268 rsecpossqs.MYD 4,383,221,760 rsecpossqs.MYI

at the moment. Should be cut in half after the optimize because of deletes. Will be looking at merge tables later, but I need this working in the mean-time.

I did some cursory looks through the source code, I've found the following:

my_chsize is being called from the mi_repair function.

Prototype for my_chsize is:

int my_chsize(File fd, my_off_t newlength, myf MyFlags);

my_off_t is a cast of unsigned __int64

inside my_chsize the function chsize is called with a prototype of:

int chsize(int, long);

basicly converting the __int64 into a long.

I'm guessing that the chsize function is a standard c function?
