列出已删除的文件并访问已删除文件的数据。
我试图读取文件系统块的块，但它显示的分区大小为0。
下面是我的python代码

import os

BLOCK_SIZE = 4096  
DELETED_FILE_SIGNATURE = b'\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0' 
def list_deleted_files(partition_path):
    deleted_files = []

    partition_size = os.stat(partition_path).st_size

    with open(partition_path, 'rb') as f:

        num_blocks = partition_size // BLOCK_SIZE
        print(num_blocks)

        for block_number in range(num_blocks):
            block_data = f.read(BLOCK_SIZE)

            if DELETED_FILE_SIGNATURE in block_data:
                file_offset = block_data.index(DELETED_FILE_SIGNATURE)

                path_start = block_data.rfind(b'\0', 0, file_offset) + 1
                path_end = block_data.index(b'\0', file_offset)
                path = block_data[path_start:path_end].decode('utf-8')

                deleted_files.append(path)

    return deleted_files

partition_path = '/dev/nvme0n1p6'
deleted_files = list_deleted_files(partition_path)
print(deleted_files)

输出显示块数为0。
如何正确读取分区？
另一种方法

import os

partition_path = '/dev/nvme0n1p6'

for root, dirs, files in os.walk(partition_path):

for file in files:
    file_path = os.path.join(root, file)
    
    if os.path.islink(file_path) and not os.path.exists(file_path):
        print(f"Deleted file found: {file_path}")

但它以for循环的0次迭代结束
