Storage devices include any device used for storing and retrieving digital information. Hard disk drives (HDDs) use one or more rigid ("hard") rapidly rotating disks (platters) coated with magnetic material. Data is accessed in a random-access manner, meaning that individual blocks of data can be stored or retrieved in any order and not only sequentially. The primary competing technology for secondary storage is flash memory in the form of solid-state drives (SSDs), but HDDs remain the dominant medium for secondary storage due to advantages in price per bit and per-device recording capacity. CD-RW (Compact Disc-ReWritable) is a digital optical disc storage format that allows information to be stored outside the mechanical HDD.

I am fairly sure that standard mechanical hard drives can map out sectors that become defective and save the drive without the user even knowing it. But, can SSD drives also do the same thing? Just wondering.

Hello - we have a 1TB large VM sitting on a particular LUN that needs to be rebuilt.  The LUN is using too many disks and the only way to free up some of those disks is to rebuild the LUN - which means we have to move the VM files off of it first.  Due to not having any other free LUNs/disks available big enough to hold the 1TB VM, we need to download it to a portable 4TB Passport USB drive.  What are the recommendations out there as to how to do this?  I know that I should be able to Browse the LUN and just download the files onto the Passport - but is that the best way to do it?  Should I do a LUN copy or something else, for any reason?

Thanks for your help.

Drives such as the Seagate Firecuda are supposed to be better/faster boot drives than normal mechanical sata drives but not as fast as SSDs or NVME. What if you use these drives for data or backup.  Is there any advantage there over a regular mechanical hard drive?
Thanks,

FEW TRICKS TO SPEEDUP PENDRIVE DATA TRANSFER RATE:

1.File system should be NTFS: If you want to Speedup Pendrive , then make sure you have NTFS as file system. You can do so by Right clicking on your pendrive and selecting Format,Select NTFS File system, Uncheck Quick Format And Click On Start.

2.Disk errors: To check disk errors go to the properties tab of your pen drive, then select ‘tools’ tab. You will find a ‘check now’ button, click it and then hit ‘start’ to fix the errors. The time taken for scan depends on the size of the pen drive.

3.Device policy: Under properties of your pen drive, select ‘hardware’ tab. Then select USB device from there that will lead you to a pop up window where you need to change settings. You can even have better performance of pen drive by clicking the option under ‘hardware’ tab.

4.Format: This is one of the effective options that many users have tried. When you have used your pen drive for quite a long time, you can speed it up by formatting the device.

Carefully test your pen drive with the factors given above to Speedup Pendrive. In addition to this, you should keep checking for these aspects regularly, say twice or thrice in a month.

i know the usb 3 drive docks
my question is : is there anything faster on the market?  
 or is sata speed comparable to USB 3

Well, the question title says it all, but what I am looking for are these features:

- Fast
- Software independant (hardware cloning, the device needs to do the job)
- Clone to a smaller sized disk (if the amount of data on the source disk allows it, does not exceed the target disk total size)

I have seen devices like Sandberg Diskcloner / Sharkoon Quickport XT Duo Clone and Icy Box Clonestation.

No idea what to expect, anyone any experience?

Thank you

I have a 500GB Flash Drive in my MacBook, but suspect the drive's nearly full.

But, in Finder, I right click the Home icon with my Name next to it, the size of the folder is 127GB.

How do I find the space on disk?

Thanks

Hello,

I have a HP Z200 workstation, model KK667ET with Nvidia Quadro 1GB graphics card
the processor is Core i5 660 @ 3,3 Ghz
16GB Ram installed (can't remember why exactly)

the workstation is primarirly used for photoshop, indesign

Every 2 years : the station is also used for database publishing which among other intensive tasks includes importing 3.000 Pre Press images as BLOB into a DB file.  Total size of the DB is 8GB.

Needless to say, when this import is started, all other running processes, have to been shut down in orde not to freeze on import.

It is time for me to reinstall this PC as it has not been done in years and has become slow.
Little has been done over the years to boost performance :

Bios Upgrade
Kingston 256GD SSD Now V2 installed

Since upgrading to a new PC is not an option, i'm looking for the best performance upgrade for this workstation

these are my options :

- install 2 cheap SSD's and use the built in raid controller on the motherboard
- Purchase the biggest processor still available for this motherboard (i have no idea how to figure that out)
- purchase an SSD that can be used on the PCI ports available

i'm no expert to which would boost performance the most,
Primarily goal is the speed up  working with the large database files since this has to be done more often.

Hi,
Firstly, I have to say the quality of answers from EE members has been EXCELLENT.
I am fairly new to server virtualization so excuse my ignorance.

 I virtualize a physical server that has C, D, E, F drives and the conversion creates one VHDX that has all the drives within it. I create my new Hyper-V virtual server using this VHDX and it has the C, D, E, F drives displayed but they're virtual drives with the ONE VHDX file.
But that doesn't seem to have the same redundancy as the separate physical drives on the original server.
Is it possible to virtualise the server and have  separate physical drives for the C, D, E, F drives?
How would the VHDX file recognize the  separate physical drives
I am not using a SAN. I have a server with lots of disk space

what is the easiest way to free up space on my C SSD Drive(128 gb actual 99 GB) . I only have ~20gb of free space which is limiting me of putting pictures on C Drive for my webshots screensaver.I do not want to mess things up or compromise the integrity of things . Money is an issue I can't replace the C Drive at this this time .What things can I uninstall remove safely without causing problems?

What does that mean?  >> solid state drive - 480 GB - SATA 6Gb/s >>
SSD’s use sata protocol?  compared to fibre channel, sas, etc
HP DL360 gen9 have these in spec quotes

Hello Experts,

On out Dell MD 3260 we are needing to add the last 13 unassigned drives to build one final array.  Is the process of creating the new Raid a pretty strait forward process?  The host mapping is not something I have worked with in the past. There is a setup tab that has "Create Storage".  Is this the wizard I am looking for?

I have a new Lenovo M900 tower with Windows 10 Pro.  
It boots from an SSD (C:).
It has a 4TB HDD (D:).
The D: drive has been disappearing so, in order to diagnose:

I wiggled the power and data connectors and the HDD came back for a while.
Then I replaced the data cable and the HDD came back for a while.
Then I removed the HDD and put it on another computer for testing.  It's running there now.
And, I added another new HDD to the computer for testing.  It's running there now.

At first, the BIOS could see the HDD but when I looked, it only listed it as "Hard Drive" but with no model number .. I believe that "normal" includes the model number showing up in the BIOS.

The replacement HDD shows up with its model number.
So, I did an experiment:
What if the power connector is disconnected?  In this case the BIOS shows "None"
What if the data connection is disconnected?  In this case the BIOS also shows "None".
So I don't know what would cause the BIOS to show only: "Hard Drive" and no model number.

Unless or until one of these tests fails, I don't know what might be causing this problem.

One thing that I don't like about this computer is that the SATA device power comes off the main board with a couple of square 4-pin connectors (i.e. 2x2 pins) using 4-conductor cabling.  So it's not like your grandfather's ATX arrangement.  If the power were bad then one could replace the PSU.  But, in this case, if the power is bad because of the mobo then the impact of …

I have here seven Hitachi 500 GB SATA drives purchased used.  The drives are definitely SATA and not SAS or Fibre Channel; see the image below.  They appear to be standard SATA drives, that's what the label says they are and that's what I expected.

The drives are mounted in server-style sleds.  There's no manufacturer name on the sled; there's a logo I don't recognize on an oval release button on the front, perhaps someone will know from the picture.  The drives are absolutely clean and dust-free.

As I tested them for function, every last one failed to present to the host system BIOS.  I've tried them on two different systems and the BIOS does not see the drive at all.  Each drive makes a brief "peep", clicks in what would seem to be a recal, pauses about half a second and then cycles through this again.

The seller claims that the drives worked before shipment.  When I pressed further on this, asking specifically whether the drives were individually tested, the response was "They worked in the server."  From this I assume that they were not individually tested for function and the seller equated "works in the server" to "works as an individual drive."

Now I can believe one, two or possibly even three drives DOA but not the whole lot, and I find it hard to believe that anyone would knowingly sell dead drives as working on fleabay.  (Side note:  The seller issued a refund, that's not an issue.)

Possibilities as I see it:

  • The drives were DOA when

I am having an issue utilizing all 4 of my hard drives on my PowerEdge 410.

The setup is Perc h700 bios raid controller, raid 6 setup, 4 hard drives 3TB each.

When installing windows it is making approximately 3TB of space unusable. You cannot format it, not even through diskpart. So the correct method would be to use UEFI GPT.

So my question. Can I boot to a USB or DVD with UEFI Formatted installation disk or do I have to use Dells OS Deployment utility. I did try the utility and it did not  like my formatted USB drive and wanted me to connect to an FTP, then it comes back and says not enough disk space on the USB when it has 8 gigs free.

Any help would be appreciated..

Hello,

Let me preface this question by saying I am a Windows guy with limited Mac experience.  My daughter, who is out of the country for a couple of months, is having serious problems with her MacBook.  I do not know the model number (can get it if it is important).  What I do know is it is roughly 4-5 years old and has a 256 GB SSD hard drive.  Her problem is that she keeps trying to delete files, but her free space has continued to shrink so that now she has less than 1GB free!  I don't know how the computer even boots.

A week ago she ran properties on her HDD and far and away the biggest storage hog were documents.  They were taking 142GB of space.  At that time, she had 5+ GB free.  I told her she should try to have 10% free, if not more, so assuming a Mac is like a PC she was still way past the safety margin.

Part of the problem I think has to do with iCloud.  She doesn't know how it got on her system, she does not like it.  But I think she has tens of GB of data (mostly pics and movies) on iCloud.  It looks like she has some kind of link on her computer, and the main file is in iCloud.  But maybe the files are local.  I am not sure.

I tried to help her two ways.  First, I got her setup with Dropbox.  She put roughly 12 movies into her dropbox folder that totaled 2 GB.  I logged into the Dropbox from my Windows PC at home, downloaded the files, and confirmed the movies worked.  I then stored them offline and told her to delete them.  After deleting the …

Hi all,

I have been searching online for an answer for this question for a few days now with no luck and I am hopeful that someone here can answer it for me.

So, I have a Seagate Wireless Plus device that I encrypted using Bitlocker full disk/drive encryption. When I plug the drive into my desktop computer using a USB, I am required to enter the encryption key to access the drive. It works fine and I am happy with this.

However, I am wondering if the encryption extends to wireless access. In other words, if someone connects to the device while it is broadcasting its SSID (by default it does whenever it is powered up), would they be able to access the contents or would it be all a jumble to them?

Please note that I do not have any compatible wireless devices to test this on hence my reason for posting this question.

TIA
