One thing to keep in mind is that very few USB controllers pass SMART diagnostic data from the drive back to the operating system. If you had a drive that was close to failure within your USB connected enclosure there is probably no way you would know about until it had completely failed. There are certain values exposed via SMART that can potentially ...

I suppose this could happen, but then again your RAID controller within your server could fail, or the Fiber Channel card that runs to your tape drive, or your tape drive itself could go bad. A consumer USB drive obviously isn't going to be as technically robust as enterprise level hardware, but if your short on funds it's better than nothing. I'd be more ...

As far as I know integrity check of copied file is done (if at all done) on much higher level. It is up for OS or software that performs copying to perform the integrity check. Regarding USB and SATA - main differences are transfer speed and availability of power in the connector (SATA does not include power) - but I assume these you already know about it ...

Never faced the problem described by your friend. Most of external USB HDD are just SATA drives in case enclosure with integrated SATA to USB adapter. Some of them, however, don't have SATA interface and have USB controller on print board instead of SATA one. In that case, because of it's rarity, it can be harder to repair physically broken HDD. Anyway, I ...

Do not touch registry unless you fully understand what you are doing. Boot from recovery/install DVD/USB and run "StartUp Repair" up to 3 times with rebooting after each run. If this does not fix the problem open command prompt: Check if a partition on disk is marked active using diskpart.exe - usually the first partition is active. Eventually if no ...

How have you used this drive? If it is quite new, the solution might be as simple as formatting (not quick-formatting) the drive. I remember a time when HDDs came unformatted and your PC had to do a format on the blocks it was going to write to, before it could actually write the files. (If the drive had been formatted completely, the performance would be as ...

If the HDD actually died, then that's probably where the extra I/O comes from -- it retrying every bit it tried to read and/or write multiple times, because the drive was failing.

You're better off with a SSD and a spare external drive for video storage. Although SSD drive prices are getting pretty reasonable at the 250GB range, which is a good ammount of storage. With a hybrid drive you only get improved performance up to a point. It will be faster for things like start up, but if you want to move large files you'll take a ...


1

The primary characteristics you are interested in are SSD size, RPM, and longevity of the drive. Higher RPM (usually) means the HDD is faster, but it will (usually) also draw more power. Since all hybrid drives are relatively recent designs, higher RPM will be faster, and it will draw more power, compared to lower RPM hybrid drives. SSD size determines ...

Hard drives are best purchased for long term storage, drop a bunch of files on them that aren't often accessed, such as images, videos, etc. They are slower, but cost significantly less than flash storage. As long as you get a decent hard drive, retrieval speeds shouldn't be an issue, so a 7200RPM drive would be a good drive for photo storage. Solid state ...

Yes, When disk utility flags a red error as unrepairable, there are two options for causes: software error where the catalog and accounting structures on the drive have become damaged and the system can't fix it without potentially losing data (or a lot of data) hardware errors on the cabling, controller or drive itself Procedurally, when these errors ...

If you delete (unlink) a file which is kept open by a process, you'll see the usage disappearing from du, but still in use by df. As soon as the last process closes the file (which happens latest when that process exits), the space used by the file will be deallocated and available in df as well.

Linux keeps a buffer space, that can only be used by root. Running sudo tune2fs -l /dev/sda1 will show the number of reserved blocks in its output. To turn off reserved blocks altogether just use the following command: sudo tune2fs -m 0 /dev/sda1

Data (files are binary data) on disks are saved in clusters. That's the way hard disk drives work. In this example clusters that are 4kb in length. There are options to format disks in smaller allocation units. To be rough, think of clusters as 4kb slots that are ready to store binary data. If a file is bigger than 4kb it will take extra slots. If it is ...

It will probably work is the best answer I could give you. The optical drive plugs into a SATA port same as a hard drive does. And in all cases, all the SATA ports on the motherboard operate at the same speed. All the HD caddy does is make the drive fit comfortably in the larger space that the optical drive needed. The reason they specify the 17R model ...

Skip that Windows utility and load smartctl Then open an admin command line in the "c:\program files\smartmontools\bin" folder and type: smartctl -i /dev/sda *Or sdb sdc etc depending on the drive location This will show the serial number in a clean easy to read format... and the drive health.

Your external drive has two parts/devices, a USB/storage "controller", and an actual hard drive. The controller in the external enclosure handles the interface between the drive in the enclosure and the USB connection you'll use to attach it to a computer. If the controller still works yet the drive itself is dead, you'll see the USB controller as a USB ...

The ope/s are best case scenario, so don't bank on 90000 in the q. That said... the picture looks like there's an issue with the SSD. The read/write levels are too low for that response time. I had a similar issue with an OCZ drive and an intel controller, where when the drive was sent to sleep it didn't properly wake up, or took a large number of seconds ...

Horrible, Horrible advise above. I mean WOW-horrible advise. :shakes head: I don't know of any modern utilities for Mac OS X that actually fix (mark) bad blocks and let you get on with your day. That being said, you need to find an older version of Norton Utilities for Mac OS to fix the bad blocks on the HD in question. Such as Version 7.0 or 8.0. Since ...

The standard way to fix a corrupted Recycle Bin is : Open on the desktop and elevated/admin Command Prompt window : type Win + R, then cmd in the Run box, and press Ctrl + Shift + Enter.

I would use PartedMagic as it puts all this stuff together in an extremely easy-to-use BootCD/USB, including CloneZilla and GParted. The advantage is that you don't have to restart so much to use different packages, it really does make the whole deal a lot faster. In terms of process I would resize the partition using GParted, then just clone the thing using ...

I've had quite a few thinkpads - I think they switched over from pata to sata around the R/T/X 60 era, since that's sata, and my old R51 was pata. So, this is approximately Pentium M era or much earlier, but before the core solos and duos. Thinkpads generally didn't use these shims over 44 pin connectors - every thinkpad I have seen with an oldschool sata ...

However, how is a hard drive encrypted, say(talking sectors and tracks here)? What encrypts the sectors, and how does it decrypt it? The implementation depends on the manufacturer, although it's common to have chip that handles this using symmetrical encryption (AES). Most vendors use the OPAL spec. And other hardware, like CPU firmware The Intel® ...

Well, Stuart's solution this has solved my problem too! I've had issues with the SSD intermittently hanging and disappearing altogether for months. Replacing the drive made no difference.

I managed to improve the situation quite a bit. It isn't perfect yet, but the hiccups are gone and the overall performance when it comes to IO is now in line with my expectations about this system.

The process you're describing from your prior employer's IT department is generally only feasible for large organizations. This is primarily because they are able to exert a level of control over their computer systems which you cannot, as simply the "repair go to guy of the family", maintain. Enterprise-level environments tend to be largely homogenous in ...

In the official Microsoft canon, there are three methods for deploying images to PCs: Windows Deployment Services (which you've obviously tried). Microsoft Deployment Toolkit (MDT).

Simplest may be to start with a brand new build, install the required OS & initial software, then backup with something like Acronis True Backup (or whatever they call it this year, it keeps changing) with the Universal Restore add-on, which allows to 'restore' to any machine with bare minimum drivers to get it afloat; you then allow Windows itself to ...

WinNTSetup is a tool which will put all necessary Windows installer files on a hard drive.

SMART values normally do not "reset" in the normal sense of the word (get set back to zero due to some event, such as a drive power-on event). An error count can, however, decrease, if the condition that caused the error count to be increased no longer exists. There are a few exceptions, but UDMA CRC Error Count is not one of them. I'm not really sure what ...

A NAS is more than a disk, an enclosure, and an ethernet port: it includes the software to handle all of this (for instance, the handling of permissions, access lists, passwords, and so on) and the hardware that goes with that software. So what you need to buy is a diskless NAS; you will find many just about anywhere, online or in a store. Just make sure ...

This can be done, but I have to give the following warning first: I highly recommend you not do this unless you value the educational experience over the security of your personal data. All it will do for you is make one drive a little bugger and the other a little smaller. It does not offer any performance advantages but has some serious drawbacks. The ...

If it is only a bootloader problem, windows repair disk should automatically be able to repair it (if you allow it of course). Boot from the repair cd and drop into the command prompt.

The private keys for these are stored with the operating system, and you need bit locker activated for the system drive as well. if you move them to another computer you will have to use the bitlocker recovery key you would of hopefully saved to an external source as you will have to use bitlocker recovery to gain access again to the drive.

This is because the Drive with the operating system on is encrypted - so the key cannot be read from there, bitlocker creates a separate system partition with the needed files to boot and check the bitlocker information provided to decrypt the operating system disk and continue boot. if you are worried about the usb stick with the key on being damaged, you ...

You could try switching between IDE and AHCI modes on the controllers that have the HDDs connected to them or you could install different drivers for those controllers. Also, some motherboards have two such controllers, so you could plug the HDDs into a different one.

I just had a similar experience to the previous late-poster. I have a Dell OptiPlex 9020 which came with 2 drives in a mirrored RAID configuration.
