How to fix corrupted blocks?

I am trying to copy blocks from Debian 10 "buster" virtual machine to external SSD which I will boot from on a Raspberry Pi.

rsync --archive --delete --human-readable --info=progress2 /home/bitcoin-admin/.bitcoin/ /mnt/usb/home/pi/.bitcoin
        135.53M   0%    9.10MB/s    0:00:14 (xfr#2, ir-chk=7777/8259)
rsync: read errors mapping "/home/bitcoin-admin/.bitcoin/blocks/blk00464.dat": Input/output error (5)

Does rsync error mean blk00464.dat is corrupt? If so, how can I recover?

bitcoind runs fine on virtual machine.

Thanks for helping out!
