Hi Maria,

The snp132 table was compressed using myisampack, which makes it 
read-only. You can unpack the table using the myisamchk --unpack command 
(http://dev.mysql.com/doc/refman/5.0/en/myisamchk.html).

You can download and confirm the size of the internal files of our mysql 
tables here: ftp://hgdownload.cse.ucsc.edu/mysql/hg19/

I hope this information is helpful.  Please feel free to contact the 
mail list again if you require further assistance.

Best,
Mary
