Error on "repair table"

[michael cook]

Hi there,

I've got a very large (21 GB) MyISAM table that corrupted as I tried to insert some data from another table (the query timed out while executing presumably because I did it from a php interface). It's not a critical DB so I'm not too concerned about it, but I was hoping to repair it nonetheless

When I tried, I got the following error:
mysql> repair table xyzprices;
+-----------------+--------+----------+---------------------------------------------------------------------------------------------+
| Table | Op | Msg_type | Msg_text |
+-----------------+--------+----------+---------------------------------------------------------------------------------------------+
| xyzdb.xyzprices | repair | error | 0 when fixing table |
| xyzdb.xyzprices | repair | Error | Can't get stat of 'D:\MySQL5.6\data\xyzdb\xyzprices.MYD' (Errcode: 0 - No error) |
| xyzdb.xyzprices | repair | Error | Can't get stat of 'D:\MySQL5.6\data\xyzdb\xyzprices.MYD' (Errcode: 9 - Bad file descriptor) |
| xyzdb.xyzprices | repair | status | Operation failed |
+-----------------+--------+----------+---------------------------------------------------------------------------------------------+

If I watch the folder as I run the repair command, it first creates a new DB file (.TMD) and then starts on the index file (.MYI). It is when the MYI file reaches what I believe is close to the full size that it spits out this error.

Any idea why this is happening?

Thanks
