Khi có lệnh ghi dữ liệu vào những sector nằm trong danh sách chờ kia, trong trường hợp vẫn còn sector dự phòng, mạch quản lí sẽ thay thế nó bằng một trong số dự phòng kia (qua ánh xạ logic - mapping). Số sector đã được thay thế được thể hiện ở mục (05) Reallocated Sector Count. while the reallocated-sector-count, which according to that test is good pre-fail indicator, is still 0. So my advise would be to examine those values for your drive/system and base your conclusions on that. I prefer the low level utility skdump which is supplied with libatasmart, the same library that is used by Gnome Disks. Cho mình hỏi cách sửa ổ bị như này với.

I've read online that "Reallocation Events" are a bad thing, so i supposed i should get a new HDD. I would like to get a 2TB Hard disk for a decent price, but also decent quality so just an average hard drive, could you point me towards a good HHD to replace this one with? I see people reccomending WD black 7200rpm hdd it's completely out of my budget, there are some 2tb hdds for 50-70$ but they're only 5200rpm and i dont know about running games off of that, maybe i should settle for 1TB 7200 rpm instead?

So they add a few thousand spare sectors at the end of the drive. When a regular sector stops working, the drive updates its firmware to use a spare reserve sector in its place. From then on, every time the drive would read or write data to the bad sector, it uses the reserve sector instead. The reallocated sector count is just the number of sectors which have been mapped to reserve sectors. The reallocated event count is how many sectors the drive thinks may need mapping. So it's normal for these counts to be high in an old drive. What you need to watch out for is if these counts suddenly...

The thing is that the two old crappy drives I have in my system are literally the only ones I have, I have no other way of backing up my data, and backing up to cloud is not an option since my upload speed is 60KBp/s and uploading ~ of data would literally take over 1200 years I did the math. 6 If your pc is almost 3 years old, a 5400 rpm hdd will run games fine, the bottleneck for you is the gpu and cpu. Its totally a waste of money to buy a 7200 for an old system. And about your hdd failing, theres only one solution buy a new one. Theres no magic trick to "save" your old hd... it could work for another year, but it could also stop working tomorrow... the only thing for sure is that the longer you use it, the sooner it fails. So, if you care about the stuff on it, buy a new one asap and copy everything there and, if possible, while you wait, dont use your pc. After that, you can even keep using it until it dies... just remember to keep the important stuff you cant get back on the new hd, and leave stuff like videogames or programs on the old one. PS You should keep the stuff you really care on AT LEAST 2 hd. A lot of times hds stop working all of sudden, in that case you woudl've lost everything. You've been lucky, so dont risk again. 7 If your pc is almost 3 years old, a 5400 rpm hdd will run games fine, the bottleneck for you is the gpu and cpu.

Well, I did say my system is nearly 3 years old but didn't mention I have replaced most of the components in the past year or so. Currently I have an i5 7600 4ghz, 8gb ddr4 ram and a gtx 1060 6GB OC, so there isn't much of a bottle neck. Most games run decently from the HDD decently as in load times etc., but large games like Battlefield, The Witcher, Fortnite and even Path of Exile take absolutely ages to load, and even when the map is loaded, the textures and models are super low resolution and it takes another 30 seconds to 2 minutes to actually load completely, plus some stuttering here and there when loading new areas, and I know that the bottleneck is the HDD because ever since I've put these very games on a SSD they load lightning fast and stuttering is a thing of the past now. I guess I will try and get a cheap-ish 5400rpm HDD and do some testing, and if it really sucks I will just refund it and wait for a better deal on a 7200rpm drive. Thanks for your input.

In that case, replacing the drive is your only option. If you don't have much money and the OS is on a SSD, then a 5400 RPM hard drive should be fine. Avoid the WD 5400 RPM drives - they have a head parking issue which can make games stutter. That pretty much limits you to Seagate or Toshiba. HGST drives are also good - even though they merged with WD, they're older Hitachi designs which don't have the head parking issue. Sequential speeds speed at which large files are read/written is more a function of how new the HDD is. The newer drives write data at a higher density. So a single rotation of the drive platter contains more data than a single rotation of an older drive. So a new 5400 RPM drive can be faster than an old 7200 RPM drive for large files. 4k speeds speed at which small files are read/written are more dependent on the RPM. The drive positions the heads in the proper track, then has to wait for the correct part of the platter to rotate under the heads. 7200 RPM drives rotate 33% faster than 5400 RPM drives, so their 4k speeds are 33% faster. But 7200 RPM drives still top out at about 1 MB/s MB/s if you enable NCQ. A SSD can typically hit 30-70 MB/s 4k speeds, which is why it's so important to have your OS on a SSD. Likewise, while the 7200 RPM drive will be faster for games than a 5400 RPM drive, it will only be 33% faster at most. If you're concerned about the speed of loading your games, you are far, far better off saving money by getting a 5400 RPM drive, and using the saved money to help buy a SSD in the future. Then put the games on the SSD. If your current SSD has enough extra space and you use Steam for games, Steam allows you to put games on multiple drives. Just move the game you're currently playing to the SSD. When you finish or lose interest in the game, move it back to the HDD. Move your next game to the SSD. If you don't use Steam and install the games directly on the D drive HDD, but you have extra space on the C drive SSD, tell me. There's a trick you can do using something called directory junctions which can make Windows think a game is on your D drive, even if you've temporarily moved it to the C drive. The bigger concern is that you are running without backups. You really should be making backups, at least of your most-essential data. If you need, you can use a flash drive to copy your most important data, then take your friend's laptop to a place with fast Internet and back up your data to the cloud.

Ah this is what I was looking for, thanks a lot. I guess I could backup the important stuff to my laptop and upload it to a cloud service through my friends who have optic fiber, as you suggested. My ssd is basically full, and I already have everything that needs to be on an SSD on it. I think I will move everything to the new 5400 rpm HDD and use the two old ones for backups but leave them unplugged unless i need them. Also, I found out about those two warnings just yesterday but as far as I know I they could have been there for years and years, so maybe it's not that bad, but then again in the past couple months I did notice a significant decrease in performance in read/write speeds so that might mean that the poor thing is close to the end of its life cycle.

I found this "Seagate Hard-disk ST2000DM006 Barracuda Sata III 7200rpm 64MB" for around 60$, but by googling around people say that Seagate is the least reliable when it comes to Hard drives and that WD and Toshiba are better, but I guess that you get what you pay for, and 60$ is pretty cheap for 2TB 7200 rpm, what's your take? Mar 25, 2010 60,403 1,078 152,940 11 You can't spend $50 on a backup drive? Time and money spent on recovering lost data will be a lot more than that. You need the main drive for files and a backup drive for that. Unless you want to be one of those people that posts on here with "I lost my important files and need to recover them" when a small amount of money and time makes a failed drive trivial. Worrying about data after it's lost is too late.

Continued usage of such hard drives can lead to permanent data loss. But you don’t need to worry because Stellar Data Recovery tool can easily recover the data from your failing hard drive. Simply download the free trial of this data recovery software and then follow through our instructions in this post. ContentsReallocated Sector Count Warning and Drive CorruptionReasons for Reallocated Sector Count Warning and How to fix itReallocated Sector Count Warning FixConclusion Self-Monitoring Analysis and Reporting or SMART is a drive monitoring system embedded on hard drives, solid-state drives, and eMMC storage. A significant and consistent increase in the reallocated sector count’ attribute value is a clear sign of a dying hard drive, indicating imminent drive failure. Essentially, the reallocated sector—also known as bad sector or bad block—is an area on the disk that is no longer safe to store data. When a system can’t read, write, or verify data stored at a particular sector, it marks the sector bad and reallocates or remaps the stored data to a reserved area spare area on the hard drive. The reserved area is set aside by the disk for normal operation of the drive and to prevent immediate data loss due to bad sectors. As the reallocation sector count increases, the ability of disk to remap or reallocate data from bad sectors decreases. This also affects the drive performance. That’s the reason why you see a warning sign in the SMART disk information. The sign is an indicator that the drive is no longer safe for data storage. And if you continue to use the drive for data storage, the data may get corrupt and the drive may turn inaccessible or even fail, which can lead to permanent data loss. Reallocated Sector Count Warning and Drive Corruption A drive with a significant number of bad sectors or reallocated sector counts can also cause drive corruption. A bad sector may damage file system information or chunk of data that contains file system information. Such disks usually turn RAW and become inaccessible. However, data can be retrieved from such disks with the help of a data recovery tool that supports corrupt drive recovery. Reasons for Reallocated Sector Count Warning and How to fix it The bad sectors are a result of logical damage creates soft bad sectors and physical damage builds hard bad sectors to the drive during its normal use. However, the warning sign may also appear faster on a drive due to intense drive usage for longer duration’s, force shutdown, overheating, corrupt file, ageing hardware, and mechanical drive issues. For instance, if you hear screeching or clicking sound from the hard drive, that’s a sign of mechanical issue which creates hard bad sectors. Similarly, a sudden fall or mishandling cause hard bad sectors on the drive as the actuator arm strikes against the platter. While bad sectors are beyond fix, you may try to fix the corruption and retrieve the data from such drive by using command prompt and data recovery software. Reallocated Sector Count Warning Fix There is no fix’ for reallocated sector count warning other than cloning the affected drive with a new one. Bad sectors—whether it’s a soft bad sector or hard—can’t be repaired. However, a drive with the reallocated sector count warning doesn’t mean that the drive will not work. You can continue using the drive as long as it runs but at your own risk. So if the data is critical, use Stellar Data Recovery Premium for Windows software to either clone the drive if it’s accessible or recover files from a corrupt impeding drive. Below are the steps that you can follow to safely migrate or recover data using the software 1. Backup Data If the drive is recognized and accessible, copy the critical files to a new healthy external or internal hard drive. Alternatively, you can also clone the failing drive with a new one. Cloning the drive spares you the trouble of reinstalling Windows and restoring the backup files. To make the process seamless, install Stellar Data recovery software and choose Monitor Drive’ to launch drive monitor utility that lets you effortlessly clone your failing drive with a new one. All you need is a new disk connected to the system and a few clicks. Besides, the software also monitors drive for errors and SMART attributes to help you prevent such data loss situations. You can also scan the disk for bad sectors. That will help you get better insights into the hard disk condition. 2. Restore File from Corrupt Drive If the drive isn’t accessible, have turned RAW, or files are not found; use the Stellar Data Recovery Premium tool to restore files from such drive. Download the software and install it on a working Windows PC. Then follow the on screen instructions of the software. Further, if a recovered photo or video file turns out corrupt, you can use photo repair or video repair tool to fix the corruption. The embedded repair tool in Stellar Data Recovery Premium can fix severely corrupt video and photos in just a few click. 3. Try CHKDSK Scan for Bad Sectors and Fix Drive Errors You can run CHKDSK scan at first—before the above two steps—but that’s not safe. More because CHKDSK scan is a tedious process and may lead to permanent drive failure, if the drive has significant bad sectors. Also, while scanning and fixing file system errors and drive issues, the scan may destroy data stored at unresponsive sectors by marking them bad. Thus, to prevent such consequences, it’s recommended that you either back up the data or clone your drive by using Stellar Data Recovery Premium software and then use the same software further to recover lost files from the drive. Once you have recovered or backed up the data safely, run following CHKDSK command on the drive to try repair and fix drive errors. Open Command Prompt in administrator mode and then type, CHKDSK /r /f X where X is the drive volume letter. Press the Enter’ key Figure 6 Running chkdsk scan to fix Reallocation sector count Conclusion Reallocated Sector Count Warning indicates a failing hard drive, which can’t be fixed by using any method or technique. This situation arrives when a system is not able to read, write, or verify data stored on a given sector, and thus marks it bad’ and reallocates the stored data to a reserved area on the hard drive. With growth in reallocation sectors, the disk’s ability to reallocate data from bad sectors goes down, which affects the drive performance and ultimately leads to drive failure. Continued usage of such storage drives will cause data corruption and loss. As you can’t fix reallocated sector count warning or bad sectors by using any technique, so you must back up and clone such drives to protect the data. The SMART Drive Monitor tool- presented in this blog post – provides an effective utility to Clone the failing hard drive, and also lets you scan it for bad sectors. This SMART Drive Monitor comes pre-bundled with Stellar Data Recovery Premium, a comprehensive data recovery software that’s renowned for recovering data from corrupt, formatted, and inaccessible drives. The software provides an effective solution to protect data loss that may happen due to hard drive failure in situations like Reallocated Sector Count Warning and more.

To keep the files protected, you should store them on local storage and a cloud service. What is the normal reallocated sector count?So 200 is the normal value. If 200 drops below 140, the disks would indicate failure. The RAW value gives a good sense of the reallocation of sector resources.
