Expecting page, got page -1 instead

[Analyticguru_09]

I'm running the below code on sas 9.3 and encountering error message

Please let me know how to trouble shoot it

libname abc "xyz\abc\sample";

proc sort data = abc.accinfo out = accinfo_accts;

by acct_no key_id;

run;

Error:Expecting page 5172, got page -1 instead

Error: Page validation error while reading abc.accinfo

Error: File abc.accinfo.data is damaged.I/O Processing did not complete.

Note: The sas system stopped processing this step because of errors

Note: There was 134234343 observations read from the data set abc.accinfo

Warning: The data set work.accinfo_accts may be incomplete. When this step was stopped there were 134234343 observations and 20 variables

file abc.accinfo is damaged.  You may need to restore it from backup.  If the libname abc is on your local C: drive, check that the drive is not damaged.
