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!!
