It really is not a straightforward answer to this. SSDs do not care about continuous writes as much as how many times any particular sector is overwritten. When SSDs first came out, something like SQL was a bad word as the operating system in general treated the drive like a traditional HDD and failures were very frequent. Since then, drives have become ...

Reads are fine, and SSD's can have their bits read from without any detrimental effect. Writes are another matter. Clearing a bit affects the integrity of the bit and after a lot of sequential writes, the bit will stop accepting new writes altogether. It can however still be read. Let me just say that the write limits on new enterprise drives are huge. ...

Writing to SSDs isn't necessarily bad. It's the writing and rewriting of a single block that's bad. Meaning if you write a file delete it then write it again, or make small amounts of changes to a file over and over again. This causes wear on the SSD's. Databases would definitely fit into this category. However according to this article, petabytes of ...

Your question is answered in depth on wikipedia but here are some reasons that come to mind. Pros: Allows for a separate filesystem on the same physical drive. i.e. NTFS (Windows), EXT3(Linux). Gives the ability to boot multiple operating systems on the same drive (dual boot). Cons: Does not protect against drive failure. Lowers the overall ...

Before you go say that RAID 1 mirrors one drive and cannot mirror twice, that is not what I mean. Actually it can, though then it is often called RAID 1E. I have a WD Black 2 TB HDD and 2 WD Blue 1 TB HDD. The WD Black is to be the main drive, and I need data redundancy. Is it possible to use the two blues coupled together as RAID drives and the ...

An offline scan is done by dismounting the volume to fix file system corruption and bring the volume back to a healthy state. Generally it is only possible with non-system volumes, and system volumes (with the dirty bit set) are scanned during boot-up before the OS is up and running completely. Self-healing is a feature built into NTFS that fixes certain ...

First for the software to use: you could try using ddrescue instead of dd. ddrescue has a switch to do only a limited number of retries. It can also use a logfile, so it records which blocks were bad. If you later feel like doing more retries, you can use the same logfile to run ddrescue again with different options (like more retries) and it will retrie ...

I would recommend using some kind of disk editor as suggested by @Karan, but... If you want to do it really hard-core badass way and use only what is included with the DOS itself then you should look at debug command. Debug: W (Write) Be very careful because even slightest mistake will be disastrous. I can not give detailed instructions right now because ...

On today's times: NO. A decent setup can easily use a setup like this : SSD for the operating system which helps specially with all post-vista windows OSes due to the fact that they have extremely many small files. HDD for main data. It can be a standard drive or a high performance one (like WD black), or even a RAID setup with only 1 logical drive Backup ...

You can install the software anywhere (if you go through the custom option in most setup programs). However you wont be able to use the app if the drive isn't attached, this seems obvious...but if the application added anything to startup then you might see issues, so be aware. In your case Visual Studio should be fine.

So what is happening? How can I fix or mitigate it? And is my drive on the verge of going to drive heaven? Your drive is dying and will end up in “drive heaven.” Simple as that. The best and only thing you can do is to get a new drive as a replacement and clone or reinstall your system onto the new drive. I mention cloning since that might seem like ...

All following recommendations are given assuming you're the only user of the PC. If it's not the case, make sure to set up appropriate filesystem permissions on tmpfs in same place you'll create directories. There are chrome cache directories under ~/.config/google-chrome/Default. On Windows, these dirs are Cache, Media Cache, IndexedDB and GPUCache. Not ...

Let's assume your import involves no updates and no deletions. So you are doing all insertions. This should only be writing new data to the transaction log. This means as data is added, it is always being written to a new sector. There might be some buffers/swap that gets churned/written to multiple times, but ignoring that, all of those inserts would ...

This is no issue. First of all, SSDs have greatly improved during the last years. Overprovisioning and wear levelling (and to a small amount, the TRIM command, though not applicable in your case) have made them quite suitable as heavy-duty, general-purpose disks. I am not using anything but SSD on my development PC (which regularly does a lot of compiling) ...

You might have better luck using a program like GNU ddrescue in Linux, it can try skipping over the bad "sticking" sectors and keep reading beyond them, recovering more of your data. I would stick to read-only operations until you have at least a copy of everything that's currently readable, even if there are corrupted sectors in your copy. Further write ...

Yes, you can. It's a hybrid configuration similar to RAID 0+1. You can search on the Internet how to set your specific hardware.

If your hard drive is failing (SSD or HDD), then it doesn't matter what you do to try to repair the OS. I have seen cases like you're describing, and your internet research is most likely correct. My recommendation is to back up everything, if it's not already too late, and replace the hard drive ASAP. However, if you really want to be sure, you can ...

Are those 4k drives? Yes, you can see that they report 4096 byte physical which is the indicator for this. The 512 byte logical reporting is a result of drive manufacturers' attempt at backwards compatibility (and thus confuses things). gpart? In your situation I would use the following commands to gpart out the disk: # -- Force ashift to be at least 12 ...

Windows cannot see the drive because your SATA controller mode (screenshot #2 above) is set to RAID. Unless you plan on doing a multi-drive RAID setup, it needs to be set to AHCI.

Rather than aliasing the drive, you might try using a powershell command to alias, rename, or move all the files. I would suggest moving or renaming over aliasing. For renaming the files the cmdlet is Rename-Item or ren Rename-Item *.html *.txt 'This renames all files ending with .html to end with .txt For moving the files the cmdlet is Move-Item or ...

If SQL Server 2005 checks the volume label, there is no way to hide the fact that the label has changed, so you need to change the way that the pictures are stored in the database. The only way I can think of to change "New Volume" to "2nd System Drive" in the database, is to reimport the pictures, in the spirit of the following : Change the volume name ...

That error likely means the CD you are installing windows from is scratched and it can't read a file during the install process. You will need to get a new CD or use a disc repair kit to remove the scratch.

You can try to do this: reattach the drive and put the symbolic link again let it sync until all of the content is in dropbox remove the drive let Dropbox erase the folder content remove the symbolic link on the web, click on the button to show deleted content mark the folder for retrieval in your Dropbox client, in selective sync mark the folder so that ...

A person could write a very in-depth whole blog about the subject. Lets see if I can find an endpoint. Most of this applies to a HD only, some of it still applies to SSD drives. Viruses and malware: Viruses more often will make an assault on the OS itself, use vulnerabilities in the OS itself, and can reside and spread using executable items. Virus can ...

First, answer on easy question: Also, if you are about to say "backup": Why is partitioning good idea instead of having external HDD? because it's cheaper. Separate HDD is more secure, but also costs more (most desktop computers don't have 2 HDDs). RAID is even more secure, but cost even more. If by "external HDD" you mean physycally-external (USB, ...
