The user cannot access a file directory, with the message of "Contains a cluster (xxx). Assuming EOF"

[DouZhaolei]

【Background】:
I reset board and run the dosfsck command once. then, The user cannot access a file directory.
The operations of "cd ***" and "rm ***" was failed.

• I checked the FSCK logs and found that a large number of file corruption check records were recorded.

• I re-do the dosfsck command,the directory will be deleted. and the system will be ok ,The fsck logs are as follows:

【question】：
The error information is in the following code segment in check_file():

if (!curEntry.value || bad_cluster(fs, curr)) {
	    printf("%s\n  Contains a %s cluster (%lu). Assuming EOF.\n",
		   path_name(file), curEntry.value ? "bad" : "free", (unsigned long)curr);
	    if (prev)
		set_fat(fs, prev, -1);
	    else if (!file->offset)
		die("FAT32 root dir starts with a bad cluster!");
	    else
		MODIFY_START(file, 0, fs);
	    break;
}

In the else branch，why not modify the file name[0] as DELETED_FLAG ? or I shoud run dosfsck with the operation of "V"?
