Storage Hardware





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.

Does anyone know if there is a way to do 5 day week backup on 5 different external hard drives rotation on server 2016 or would I need to purchase software to do that?

I'm having problems with my workbook often going into a 'not responding' mode even when auto calc is turned off. It usually lasts for a few seconds and on one occasion the work book crashed and I was fortunate to be able to recover it fully. I can't afford this to keep happening as I will be turning on auto calc and linking it to an external datafeed source and often leaving the PC unattended. The workbook is around 350MB and has dozens of formulas, some complex.
My PC is high spec i9  16 core processor 1 TB hard drive 90% free, 64GB ram. 2 graphic cards can support up to 8 monitors, currently using 3.
Any help much appreciated
Can somebody help me please. I have 2012R2 hyper-v cluster with two nodes and an IBM Storewize v3700 connected over SAS. I can't figure out how much free space there is in storage volume (I think free space isn't freed up on storage)

For example, in hyper-v cluster console, there is clustered volume "brzi" ("fast" in english) which corresponds to volume on storewize. It shows size of 1.50TB and free space of 676GB, app 50%.
In Storewize GUI, i have 1.5TB pool with 1.5TB volume ("brzi"), that is available to cluster hosts, and it's seen in the image above as clustered share vo .
But when looking in properties of that volume, free space doesn't match free space reported to the cluster (676GB). The files when selected from host, really takes only about 50%.
Storewize VolumeIt's seen as space is entirely used....

Thank you
Hi dear EE fellows,

I'm kinda stuck with setting up our new Oracle 18c databases and/or I'm just missing the forest through the trees ;-)

We want to have server A running 18c with OMF, which reside on a SAN storage. Now, we want to have a server B as some sort of cold backup. If server A might crash, we want to start up server B, which should also be able to run with the SAN files. Sure, we'd have to use the last backup, do a recover and apply the archive logs ect... That is NOT the point. How do I have to setup the instance on server B so that it can also run against the SAN storage (e.g. shut down server A, startup server B).
In the end, we want to have 2 instances running on 2 separate servers (where 1 would always be down) which are able to "connect" to the very same SAN storage (OMF).
The databases should/will be Oracle 18c SE2 and no, we don't want to/can't use RAC.

Thanks for your help in advance ;-)

Cheers, Alex
Hyper-V ran out of space so I deleted a total of 300gb of old SQL transaction log files and old database.
I now have 300Gb of free space on the Hyper-V but the physical host drive is still out of space. Why and how do I get the 300gb of free space back on the physical disk.  FYI. The host server has a total of 900gb. The drive is partitioned into a C: drive for Windows OS (200gb) and a D: drive for the Hyper-Vs
(700gb). The D drive keeps running out of space and then shuts down my Hyper-Vs. I thought after deleting 300gb off the Hyper-V that it would also give the 300gb back to the host D drive. Desperately need help and please give step by step instructions.
Hello and Good Evening Everyone,

           Within the last few days, I have noticed that my Acer laptop running Windows 10 does a check of the internal hard drive and scans and repairs problems with it each time it is booted.  That said, I am wondering if my hard drive on my Acer laptop perhaps might be failing.  Does Windows 10 have an integrated utility which checks the physical integrity of an internal hard drive?

            Thank you

How do you get into SAFE MODE on a PS4 with a broken Power Button?  I can't believe there is no other way to do it...but the unit keeps shutting off and I want to reinitialize the OS on a new hard drive.
I have a dell PowerEdge R510 Server with 3 hard drive Raid 5
One of the drives is flashing an orange and green light.
Found something strange on an Older PC (8 years old Vista for Business) that I cannot figure out. I have a Hard Drive that is almost at capacity and I cannot figure out what is filling the HD up. I was hoping to recover the space and use it for new projects and ventures. The image shows less than a GIG when the folder is open. However looking from the Computer's File Explorer you can see it is near capacity. I know what hidden files are but cannot seem to figure out why I cannot see them if they are there. Hoping to salvage some space.
A few notes:
1. The drive was COMPRESSED. Did not know that. So not sure what UNCOMPRESSING might do? Since there is clearly not enough room to expand on that HD. Might be able to send to another?
2. That machine has slowed a bit and suspect that it may have something to do with that. OS is on C but I think that something related to the OS is on D:\ May just be restore points or backups. Of course I cannot see them?
3. The Drives are individual and not partitioned from what I can tell. See second image.
Why can't I see these files. File sizes do not match and I cannot tell if files are Hidden? BaffledThree separate Hard drives.

Doing some cleanup around the house. Realized I have 3-4 PC's sitting around only used for clients who refuse to update older machines. I keep the older software on them for those special situations. I also have large hard drives on them. I thought it might be a good idea to do one of a few things. Your wisdom appreciated other than the obvious throw them away!
  • Salvage any and all components HD's Wireless Adapters Graphics Cards USB etc.  I am guessing that some of the HD should work universally right?
  • Move some of them over to a new modern Motherboard 64 bit with more horsepower RAM performance. ( I realize that the problems I may run into are compatibility, non-supported drivers OS issues and probably BIOS stuff. )
  • I was thinking by consolidating some of the data I might be able to get some more use like backup space etc.
  • Take the hard drives and create some kind of file server and or printer server with a machine or two.

Out of Curiosity, I was wondering since several of these have older OS's on them would it be of any value to keep a few older OS with software that works with it Crystal Reports Business Object Enterprise. Tableau Desktop on some of them. Is it possible to put them on a box that at StartUp allows me to pick and choose what OS I startup with?
  • One - XP, 2 HD
  • Two - Vista for Business, One - Win 7 Pro

Hi, I did a chkdsk on the main C drive, results attached. I've been having a freezing problem, and have put up a few questions here about it. In the most recent one, it was recommended that I have Windows reinstalled.  My tech locally hasn't looked at the laptop, but he says freezing is most often a hardware problem, and I should replace my hard drive.

I'm on Windows 7, and have been fighting going to Win 10, because it honestly seems to be a pain in the tush. My partner runs it, and has had all kinds of issues.

Anyway, I also tried running HDDscan, and got the attached SMART report. If you want me to run anything else to show the health of my hard drive, I'll be happy to oblige. Thanks.
New Dell Optiplex 5060 Win10 Pro with 512 GB SK hynix SC311 M.2 drive. Everything running fine.  Except there is a red circle with a white X in the middle next to the C drive. Also hard disk sentinel shows a critical problem involving wear-out indicator.  (See below)  

Called Dell technical support. Support rep said that since everything’s running fine it might be a software problem. Said to do a clean reinstall of the operating system.  I can’t conceive it’s a software problem and I’m not going to wipe and reinstall everyone based on this.  

I’m not sure it’s an important problem either. Power on time for the drive shows only 19 hours use. I also downloaded the SK hynix drive manager kit. It didn’t show any problems. Under “Life Remaining” it shows “Unavailable”.  The Smart reporting itself might be crazy and the drive could last another 5 years. Is this worth pursuing with Dell?  

I have a RAID 5 array of 4 x 4TB disks, I want to swap each disk with a 10TB disk allowing rebuilding between each, then expand the array size at the end to utilise all the new disk space. I’m using Intel Raid web console 2.

I’m hoping the general idea is ok? I’m doing this to prevent data loss, otherwise it’s destroy the array and replace disks.

How do I remove safely and replace a good/configured disk?
My Dell computer does not boot.   When I turned it on this morning, it got as far as the splash screen listing the hard drives and ctrl-I to enter configuration.   It froze at that point.   When I switched it off then on again it did not even get as far as the splash screen.   The LED on the front that normally flashes does not do so.   I tried a hard drive with Ubuntu on it, but it still did not boot.
We have done this over the years with a variety of different software but wanted to get some feedback from you experts.

What is the best commercial and/or open source software (that is user friendly) to clone a larger drive (example: 1TB SSD) to a smaller drive (example: 480GB SSD)?

(If it matters they are Windows OS drives.)
there is probably an explanation for this, i just don't know what
i have a dell desktop that came with a 128gb ssd and have outgrown it
i got a 2tb WD blue ssd and used clonezilla to image it and was successful
however, disk management does not see the drive as 2tb, only as 128gb
it shows 2tb in the bios and diskpart but can't do anything else to extend it since it doesn't see the drive size correctly
device manager sees the WD model number correctly but as a 128gb capacity

I'n not familiar with Proliant servers. I seem to be getting mixed info on drive array on HP Proliant DL380 Gen 5 server. The front panel drives are listing these as 60 GB drives. There are 5 of them. If I go into the system management home page, on the array controller, it lists the physical drives as 466 gb (I assume 500 gb) drives and there are 5 listed in the physical drive listing. I will attach a screen shot of the management console. I'm also attaching a shot from the front of the server and the E200 array that shows no physical drives. Not sure why there are 2 array's in the computer. The first was an P400 array.

One of the drives in the front panel is showing a solid green LED light on. From what I've been able to locate, that indicates the drive has failed and has been taken offline by the controller. Is that right?

If I go to replace the drive, what do I actually use? I see that there are 60 GB hot swap drives that were made for that unit but the management console is giving me a different picture so I'm not sure what to try.

Any advice would be greatly appreciated.


Wondering if anyone has noticed something like this with a PC that has a PCI-e NMVE M.2 Drive.

The PC has a very slow network speed compared to other PCs at that location. When physically moved to a different spot in the building, the network speed picks up to be on par with the rest of the PCs. I’ve eliminated the network cable as an issue by making a brand new Cat6 cable and running it directly from the switch to the PC (bypassing any other equipment) and not seeing any changes.

The oddest thing, when we take a different PC from that location and plug it in where the problem machine is, then it slows down. Put the machine back where it came from and everything is fine.

So we are basically chasing our tails and this was brought up. Are M.2 PCI-e NVME drives susceptible to electromagnetic interference?

Or should we call an exorcist?
I noticed a couple reviews with Highpoint's new M.2 NVMe RAID controller . What I noticed  was that there were testing with consumer NVMes which begs the question about what is going on with TRIM/Garbage Collection.

   Everyone was staying away from consumer SSDs in servers primarily because RAID controllers didn't support TRIM. Have they made any major improvements to TRIM or Garbage Collection?  Do any RAID controllers at this point support TRIM? or are you still limited to Enterprise SSDs/NVMes in servers for power protection and garbage collection?

I need the Experts' help navigating the external backup world. I have always used WD MyBook, but now I have so much on my external drive, I want to "backup my backup".

I'm interested in the new solid state drives, but I could use help in how to proceed. A friend recommended for good price/reliability. But what kind of USB connection would I need, and how do I know my computer has the correct type?

As you can see, I need "backing up your computer for dummies".  Would I connect both devices, the old MyBook & the new SSD to my desktop? So, pitch in and give me the "tutorial for dummies" re: backup. Thanks in advance.
I have a scsi card that we are trying to pass through to a virtual machine using vmplayer. The SCSI card is used to control a high end printer and not for a hard drive. I have considered vsphere or hyper-v server but want to see if it is possible with what we already have installed .
 I am going to buy HPE PROLIANT ML110 GEN10 SOLUTION - TOWER - XEON SILVER 4110 2.1 GHZ - 16 GB server (Part# P03687-S01) without a separate RAID controller (likeHP 830824-B21 Smart Array P408I-P S) to cut down on cost.

 Last time, I purchased HPE MIDLINE - HARD DRIVE - 1 TB - SATA 6GB/S (Part#: 655710-B21) for this server.
 However, this time I wanted to get 2TB HD of the same kind, but ran into  "HP 2TB 7200 rpm SAS-3 3.5" Internal SC Midline Hard Drive (MFR # 818365-B21). It is SAS even though it is only 7200 RPM.

Is there an expert out there who have used this hard drive? If yes, is it:
(1) Compatible with HPE PROLIANT ML110 GEN10 - TOWER - XEON SILVER 4110 2.1 GHZ - 16 GB?
(2) From performance standpoint, is it worth paying more to get this HD over a typical HPE 2TB SATA like "HPE Midline - Hard drive - 2 TB - hot-swap - 2.5" SFF - SATA 6Gb/s - 7200 rpm (Part# 765455-B21)"

 I am going to get three of these and set up RAID 1 with one hot spare and will run Windows Server 2016 with two virtual servers (first VM - W2016 Domain Controller, second VM - W2016 Terminal Server running Quickbooks and other Tax software for two concurrent users).

Link below says:  The iCloud Drive Archive folder appears when you turn off iCloud Drive…

How (and why) would this occur? - not done with my knowledge

There  are currently 4 iCloud Drive (Archive) - X [X = 1-4]  files on my hard drive.

Why are the created? How do I prevent these files from being created?

The iCloud Drive Archive folder appears when you turn off iCloud Drive. Instead of just dumping your Documents and Desktop files into your local Documents and Desktop folders, where they could create quite a mess if you already have files there, it puts these in these iCloud Drive Archive folders so you can look in them and figure out what to do with these files orphaned by turning off iCloud Drive.
I've recently built a new pc


I've installed windows 10 from a USB stick onto the SSD and that seems to go fine but when it restarts it can't find the boot device.

If I go into the bios and exit - the system boots into windows fine.

Latest BIOS - Any ideas?
I'm using a SATA hard drive adapter cable to use a known good hard drive for external storage. My PCs (Windows 7 and 10) see the adapter as "USB Drive" but show the drive capacity as 0 bytes.

When I view my drives in Disk Management, it shows Disk 1 as Removable with "No Media."
"No Media" image from Disk Management
I've gotten the same results using another known good drive. I've also had similar problems with other SATA hard drive adapters - including ones whose IDE adapters worked flawlessly. So far I've always given up and gotten an external case to make it work. But I liked the convenience so much in the past that I'd really like to know why this isn't working for me now.

Any help you can offer would be greatly appreciated.
