Hi,

Here are the details:

shackleton:sulla:$ /usr/lib/csih/getVolInfo.exe /cygdrive/z
Device Type        : 7
Characteristics    : 10
Volume Name        : <USBSTORAGE>
Serial Number      : 0
Max Filenamelength : 256
Filesystemname     : <FAT>
Flags              : 3
  FILE_CASE_SENSITIVE_SEARCH  : TRUE
  FILE_CASE_PRESERVED_NAMES   : TRUE
  FILE_UNICODE_ON_DISK        : FALSE
  FILE_PERSISTENT_ACLS        : FALSE
  FILE_FILE_COMPRESSION       : FALSE
  FILE_VOLUME_QUOTAS          : FALSE
  FILE_SUPPORTS_SPARSE_FILES  : FALSE
  FILE_SUPPORTS_REPARSE_POINTS: FALSE
  FILE_SUPPORTS_REMOTE_STORAGE: FALSE
  FILE_VOLUME_IS_COMPRESSED   : FALSE
  FILE_SUPPORTS_OBJECT_IDS    : FALSE
  FILE_SUPPORTS_ENCRYPTION    : FALSE
  FILE_NAMED_STREAMS          : FALSE
  FILE_READ_ONLY_VOLUME       : FALSE
  FILE_SEQUENTIAL_WRITE_ONCE  : FALSE
  FILE_SUPPORTS_TRANSACTIONS  : FALSE

The same details are reported for two different types of device.


In addition to the core dump with 'ls -la /cygdrive/' when the device is
not available, I am also able to generate core dumps under the same
conditions (with build v3_1_0_0_8) from the following commands:

	man bash

	mutt

The strace for the 'man bash' core dump is 4.2M, so I have extracted
some of the apparent error event into the attached file to see if they 
may be of help.

NOTE:
-	The following file is not present:
	C:\cygwin64\usr\share\locale\locale.alias

Regards,
