How to match the first word and print only that line in UNIX?

Below is the file

DISK-A    109063.2  49  31  40.79
DISK-B    110058.5  49  44  57.07
DISK-c    4402.4    2   1   2.14

from the file, i want to search for 'DISK-A' and print only that line with the first word matching to DISK-A and the output should skip DISK-A.

Desired Output: (If i'm searching for 'DISK-A')

109063.2  49  31  40.79

Any suggestions would be greatly appreciated.

awk 'sub(/DISK-A */,X)' file

Thank you for the swift reply:b:
