Hitachi 160g mobile hard drive, help recommend a Hitachi mobile hard drive

The best ones are Seagate and Hitachi, about 600-800 yuan, and it's not bad to buy a Lenovo, about 500-600 yuan (the Olympic commemorative version also gives a Bird's Nest and a Water Cube medal, it's very cost-effective, ** at 599, very beautiful), Newman's is about 500 yuan.

Other brands are very cheap, but you want to keep your data longer, or buy Lenovo or something, I hope mine will help you again.

To assemble, the hard disk case is also the key, the ** hard disk box from 20 yuan to several hundred yuan are available, accidentally narrowed by the seller, you can choose better air permeability, more**.

It's true, but it should be Hitachi's old model, the shockproof function is very poor and poor, it is not recommended to buy, the new model**in 600-1000 looks, you should know that the mobile hard disk is the most afraid**, so in order to keep your data longer, buy a slightly better, don't buy** again**, can not guarantee the quality, you can buy a better one in Shanghai's computer city 500-800, I hope mine will help you.

I think to go to the Internet, all kinds of mobile silver plates are available, you can compare**, and then you can buy it online, or buy it in a computer supply store near you, don't be a big store, because you can't bargain, you can see more on the Internet to know how much the general hard disk is, and then go to choose not easy to lose.

The all-new Hitachi slim mobile hard drive NESO

The 160g one is around 320.

According to the IT depreciation rate.

Brand new hard drives are 20% off.

It's about 250 or so.

Of course. This is a complete **.

Your own hard disk enclosure + old hard disk.

According to the new goods in the market**, you can start with a 7% discount.

About 200 or so.

The structure of the mobile hard disk = notebook hard disk + hard disk enclosure;

No, the actual capacity is a little smaller than reported.

According to the computer conversion, 1 bytes = 8 bits; 1 kb = 1024 bytes; 1 mb = 1024 kb; 1 gb = 1024 mb

However, hard disk manufacturers often use simpler algorithms, namely: 1GB 1000MB, 1MB=1000KB, in this way, the actual capacity of the hard disk identification 80G is only 80 1000 1000 1000 1024 1024 1024 1024 = or so, that is, about 76300M.

Formula for calculating the size of an integer partition of a hard disk (calculated by hard disk partition, including calculation**).

Whether you use fdisk or other partitioning software to partition, you need to enter the partition capacity to be allocated, this value is in MB, but if you enter 2000MB, you will not get 2GB of integer capacity, but; As we all know, 1GB is not equal to 1000MB, but 1024MB, but the author found in the actual partition that even if you enter 2048MB, you will not get 2GB of the whole number, but still get it, which has an error of about 5%.

Originally, the capacity of the hard disk is in MB (megabyte) and GB (gigabit) units, the early hard disk capacity is relatively low, so most of them are in MB, in September 1956, IBM manufactured the world's first disk storage system only 5MB, and now the capacity of the hard disk has already leaped to the GB level, the capacity of the mainstream hard disk has reached 80GB, 120GB, and some users also use 160GB, 200GB of massive hard disks. When calculating the capacity, hard disk manufacturers use 1000 bytes as 1KB, every 1000KB as 1MB, and every 1000MB as 1GB, while the operating system calculates the hard disk capacity with 1024 as the base system, 1KB per 1024 bytes, 1MB per 1024KB, and 1GB per 1024MB.

In addition, the hard disk will also occupy some space on the hard disk for system files after partitioning and formatting, such as storing information such as disk structure and data storage location, this part of the space cannot be used to store other data, the operating system will only report the capacity of this part of the deduction, and the system space occupied by different file systems will be different, so there will be a certain difference between the hard disk capacity and the nominal capacity displayed in the operating system. If you want to get the capacity of an integer gigabyte after partitioning, then you can calculate it according to the following formula:

m=（g-1）×4+1024×g

Here m is the value we should input when partitioning, and the unit is MB; g is the desired integer partition capacity, and the unit is GB. For example, if we want to get an integer partition of 5GB, then we should enter (5-1) 4+1024 5=5136 when partitioning, and if we want to get other integer partitions, please calculate it by ourselves according to the above formula.

Normally,My Hitachi 7k500 formatted after the division adds up only。。。 Because the conversion unit of the manufacturer and the operating system is inconsistent, the manufacturer is 1g=1000m=1000000k, and the computer is 1g=1024m=1048576k, and the difference in the middle comes out.

Computer storage looks like this. The manufacturer is converted with 1000. The computer is calculated on a 1024 basis. Normal. It's that big.

This is normal, my Seagate is the same as you, this is because the industrial calculation is 1000m = 1g, so there will be a 5% error in the calculation on the computer.
