consider a disk with a sector size of 512 bytes, 2000 tracks/surface, 50 sectors/track,

5 doubled sided platters, average seek time is 10 msec.

Assume a block size of 1024-byte is selected.

Assume a file that contains 100,000 records of 100-byte each is to be stored on the disk,

and NONE of the reocd can be spanned 2 blocks.

How many blocks are needed to store the entire file??

If the file is arranged sequentially on disk, how many surfaces are required??

Now, i have calculated that 10,000 blocks are needed to store 100,000 records.

But i am not sure how to find out the answer of the surfaces required.

I only calculated the capacity of track is 25KB

and capacity of surface is 50,000 KB

But I don't know how to calculate the number of surfaces...

Could anyone help me how to get the answer?

Thanks a lot!!
