Resurrection of the hard disk new place - ORICO Oricon "crystal enamel" mobile hard disk single test

The 250G WD E-HDD that was purchased in 2010 has been in service for almost 6 years. After graduating from college, it was hung on the router for off-line downloading. However, recently it has been a problem. It has been read on the computer and its files have been deleted. No more. In addition, I once fell down once before cleaning up the desktop. I suspect there was a bad one. Before I heard that Western Digital's mobile hard disk is like this. . . (If you borrow a picture on the internet, please contact me if you infringe on the author's rights.   )

Borrowed map

That is, the USB port and the hard disk PCB are integrated, not the structure of the SATA interface + hard disk box, so once the disc is scrapped, there is basically no rescue. So the shell was opened with an almost violent method. Surprisingly, this product is not the same as the online style, a 250G blue disk and SATA to MINI USB board (yes! Yes, that is MINI USB interface ), it seems that there are still plays, and thus re-plug the MINI USB, but fortunately HDTUNE can also sweep, sweeping the speed of 20MB/s again, in a position about 7G a big red dot. I was thinking that the fate of this cargo will be estimated. Online collecting a lot of methods such as partition shielding, or wandering do not understand, then decided to use a most primitive party, formatting.

First came two quick formatting, and then the egg, the red dot is still dazzling. At this time, I saw the formatting option next to the quick formatting hook. I was thinking that anyway, if I were to be a living horse doctor, I would rather let it come slowly. Start! After half a day of progress, I still thought I would be dead in my computer. However, other programs can all function normally. To minimize it, no matter what it is, there will be a trace of green after about 20 minutes. . . Nima, not checking the speed of the original format is such a turtle speed, coupled with the USB2.0 interface, the speed is even more impressive. In this way, from about 6 in the afternoon to about 10 in the evening, the disk was silently turning next to me, formatting it. After formatting, bring it back to the dorm and take my E7240 and continue scanning again. A miracle appears! It hasn’t been green ever since sweeping to 10G. However, it was a bit late, plus the hard disk was still noisy at quiet nights, interrupting the scan before going out the next day. Speaking off topic, the E7240's speaker sound quality is really good, did not see this certification, but the sense of hearing for my fungus is better than my ASUS A53's Ott Blue Star certified speaker sounds good More than that, the sound is very clear, unlike the A53, which gives people a very stuffy feeling. Here is my virgin sun in Aunt Zhang, that is the E7240.

The second day after sweeping back, I noticed that I was full of green eyes and I was overjoyed. Not only was the hard disk alive, but also because I could finally buy it and buy it. . . How much does it cost? What kind of buy? It's too expensive, it's cheap, and you can't just look down on it. Simply say that Daddy's house has a stroll, and you'll see this hard disk box. USB3.0 interface, transparent shell, the most important thing is to look (preferably).

What can be painful for the eggs is to pre-load the goods! Sale! Customer Service said that on the 30th delivery, but in fact, I do not actually have a lack of storage equipment, simply pick it up. The result is on the 21st, open Taobao suddenly found that the annoying 1 to be shipped is not, until the receipt of more than one, half a day did not respond to picking things up, point to open the goods to find the original hard disk box original delivery Now. . . Customer service deceives consumers! Say good 30th before delivery? But to see if I am so generous or not, they have taken care of them.

The packaging is very simple, inside and outside the two layers of carton packaging, opened the second layer of the carton can see the hard disk box, hard disk box outside a protective cover, should also be more common packaging.

The layer below is the useless paper with two manual descriptions and the USB3.0 data cable. The cable length is about 50cm. It is just right, it will not be too long and it will not be too short and inconvenient.

Remove the first layer of packaging film hard disk box surface is also affixed with a layer of plastic film, do not know how to remove this film it can maintain its value for how long.

The front of the hard disk can see two solid-state capacitor package pads empty, do not know if it is cost control or what reason. This side has USB3.0 interface and SATA3 interface (backward compatible with SATA2), plus some inductance and capacitance components.

On the back is NS1068X SATA bridge USB3.0 interface chip, next to a 25D40T chip, did not find the data, it may be EEPROM like it.

Not too cool inside the hard disk box is not very clean, inside the box there is actually a large piece of dandruff-like things, although cheap and not what gold and expensive things, but good care to pay attention to hygiene. . .

The front cover of the hard disk box is a push-pull type. The thumb presses the shell surface and then pushes it back to open it. The front surface is pushed open. Unlike other related switch products, the PCB part is wrapped. Need to use a little effort to push open, but the hardness of this set of shells in the hands should also be more comfortable, do not worry about accidentally by rotten.

Doing things right, insert the hard drive. Hard disk thickness of 9.5mm is just good, hard disk box randomly distributed shock pad or something like an increase pad, so 7mm thick hard drive into it may need to find something to pad to secure.

The hard disk status indicator is on the back of the hard disk. When there is no data read/write status, the blue LED is on.

When the data is read or written, the magenta LED flashes

Since the hard drive that was removed is a SATA2 interface , the basic SATA2 is now commonly used, and the speed difference is nearly doubled. Therefore, it is only suitable for entertainment testing and is not suitable for reference. Reading and writing large files is stable at about 51MB/s.

Comparing the speed of a U disk of the 32G Samsung MLC SM3260 under the control of a forum God DIY, the gap is still quite obvious.

The 32G brother has come to show his face

There are also speeds that the value of friends through the SSD, in this reference to you valued friends.

Finally, test the power consumption data of the working state:

The blue LED is constantly on. The voltage is 5.22V and 0.26A at standby.

Read and write voltage is basically unchanged, the current increases to 0.67A

Finally, let's take a picture of the working status. The overall value of the LED is bright when the LED is lit. The LED light will reflect and refract from the transparent shell to the whole body. For value-friends who like transparent styles, if you have an idle 2.5-inch hard drive, you'll still have it. The only thing worth worrying about is whether the shell can withstand the ravages of time and whether it will become a big face at some time in the future.
