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.

We have a 4 usb external hard drives need to connect them to our PC.  We have a usb hub with no ac adapter.  We were told that since there is no ac adapter on the usb hub, the small electricity supplied to the hub will nit suffice to power all the drives.

Our notebook has a USB which supply power.  We can power down the notebook and connect a phone to the usb port and it will charge.

Question, if we use a non-ac usb hub and connect it to the power usb of the notebook, will it be the equivalent of a ac-usb hub?

Please advice.

Hi there, I have a MacBook Air that was written off after having water spilt on it. I suspect the SSD hard drive is OK and I want to try and recover the data off it. I have searched the net and found plenty of adaptors for connecting earlier mac dives (2012, 2013 ect) but the interface is different for the 2015 drive.

Does anyone know what this drive interface is called and an adaptor I can use to connect it to another computer (Prefer USB3) to recover the data? .

Recently my one and only 1 TB hard drive failed.  I bought a 2 TB hard drive to replace it and was able to restore my system via a Carbonite image.  

My confusion is that when I open "My Computer" and look at drive C:, its size is reported as  919 GB.  However, using the Disk Management tool tells me the following regarding healthy partitions:

78 MB, OEM partition

12.25 GB NTFS Recovery partition, system, active, primary partition

1850.69 GB NTFS OS (C: ) OS partition boot, page file, crash dump, primary partition


So what is actual size of drive C: ?  Is there any way to access the entire 2 TB of disk space?

(By the way, I am using Windows 7 Home Premium on a Dell XPS computer.)

What is a recommended software package I can use to test if an SSD drive is failing? Also, would prefer it to have a bootable cd or USB image.

I have used SpinRite and HDD regenerator in the past.

What do you all suggest I get?

We have several PCs that can write to an external HDD, but cannot connect to our network. These machines are locked down and we have no control over them. They save daily backups to external hard drives or flash drives. We would like to get those back ups on our network so that we don't have to manually move the HDD from the PC to the server in order to copy the data.

Is there a way to use a device of some sort that would act as an external HDD, but that has network ability?

PC -->HDD (via USB) -->??Device?? -->Network. That way we can pick up the backup from the HDD through the network.

I looked into Pogoplug, but they are defunct. NAS would work if it had a USB type B port (or micro) that would allow data to be written via USB. All of the NAS' I have found so far that have USB have the type A port that is not designed as an input.

Hi guys,

Scenario:
Dell blade server which has smoke damage due to a fire in the building.
HDD's SATA seem ok.
VMware ESXi

Aim is to get the VM's out.

Is there a way to recover a Raid 10 array of 6 hard drivers, BUT i only have the ability to see one HDD at a time via a PC (maybe I will need some raid recovery software).  I have a dual bay SATA caddy that I intend on using.

Any suggestions people?  Any other ideas?

Many Thanks.

I rebooted our file server which is a 2008R2 used only for file services.  There were two Microsoft updates one of which was a service pack update.  It has now been close to two hours and on the screen it still says that it is shutting down.  The blue circle to the left of the text is solid and not spinning.  It has (8) 2 TB hard drives in a RAID 5 array and the last drive is blinking steady green with no other activity.  My question is: Is it possibly still doing something or is it locked up?  I don't know whether I should force another restart or not. Any thoughts?

Hi All,

Can anyone here please share some explanation and the comments on my Lefthand P4300G2 Storage array warning alarm?
LUN Utilization

Event: EID_RECLAMATION_THRESHOLD_STATUS_SOFT E00020401
Severity: Warning
Component: SAN/iQ
Object Type: Cluster

The cluster 'PROD.CLUSTER.2.1' is becoming full.  The cluster 'PROD.CLUSTER.2.1' Space Reclamation value is at 94.13% of capacity.  This value exceeds 90.00%. When the cluster exceeds the Space Reclamation limit, the application writes to thinly provisioned volumes in this cluster may fail, and other tasks that require cluster space may be impacted. Some actions to reduce capacity utilization on the SAN are to delete volumes and snapshots, reduce snapshot retention, add nodes to the storage cluster, use thinly provisioned volumes, move volumes to other clusters, etc.

Open in new window


I have created RAID10 LUN and maximize it as 11.5 TB VMware VMFS in the production environment but I'm worried about the above alarm if it is safe to continue or not?

Any help and comment would be greatly appreciated.

Thanks.

Ransomware-A Revenue Bonanza for Service Providers

Ransomware – malware that gets on your customers’ computers, encrypts their data, and extorts a hefty ransom for the decryption keys – is a surging new threat.  The purpose of this eBook is to educate the reader about ransomware attacks.

Dear Experts,

I changed my laptop's ProBook 4230s from SATA to SSD.

Now it gives me the 3F0 error.

Any idea how I can resolve this?

I have a client who had some Internet issues yesterday and while on the phone with her ISP, she apparently began unplugging power to various random devices, unfortunately including her Buffalo Linkstation NAS.

Apparently she felt it was not coming back online, so someone in her office pressed the "Function" button.  He says the LED changed color (can't remember what color) but at any rate, the NAS is just flashing a red LED.

This NAS has info already stored on it.  What's the best way to proceed without jeopardizing data?

Thanks.

Afternoon all,

Ok, so I'm getting some new hard drives since my current drives are too full... Kinda obvious really.

I'm looking at the WD Blues and I can see there is the 1TB EZEX Blue model. However there are these new EZRZ models which are more expensive yet spin at 5200 RPM only...

Why are they more expensive? Are they better or not so much

Cheers

Alex-

I need to analyze a large number of hard drives to see what files were created by a particular user.  What is the best forensic software out there to do this with?

I have vmware workstation on my window 10 and several vm machines and servers .
question.
all machines (file) I keep on a separate drive (not the same as the os and application) would you recommend using a ssd or sas instead of the stranded sata or there is no need

Hi People,

I'm currently running 2x Thecus NAS N-16000 Firmware 2.04.06a across two different Campus building.

Can anyone here please assist me how to assign the 4x Hot Spare disks that were replaced with new ones into the existing RAID60 group:
2
Into this degraded RAID group:

3Any help would be greatly appreciated.

It has already lost 4x HDD hence I notice they are all must be replaced manually on the physical slot and then manually added again to the RAID group as above, but I do not know how to do it and what's the risk ?

Thanks.

Hi,

Configuration Raspberry Pi 3 with camera
QNAP TS-453 Pro

I have a Raspberry Pi 3 up and running with the help of this image: http://ronnyvdbr.github.io/RaspberryIPCamera/
The guy who developed the image has a blog where he describes how to connect the Raspberry to Survellance Station:
https://random-notes-of-a-sysadmin.blogspot.nl/2016/03/howto-set-up-raspberry-ip-camera-on.html

I tried it and can connect to Surveillance Station, using these settings:

Camerabrand:       Generic Model
CameraModel:      Generic RSTP
Cameraname:        Camera 1
HTTP URL:              /
IP address:             192.168.10.10
Port:                        80
RSTP Port:              8554
Username:             <empty>
Password:              <empty>

When I use the rstp url in VLC, it works great: rtsp://192.168.10.10:8554
On Surveillance Station, every now and then the connection works, the camera in connected and I can see what it's filming.
After less than a minute the camera is disconnected.

For now it looks like the only times I had a successful connection when I played the stream in VLC as well....
But I can not reproduce that, because it's not working this way every time....

What could be the cause of this ?

Hi,

I am in the process of creating a Hyper-V Replica Server and I have been looking at using Storage Spaces.

I have a HP MSA60 with 6x 3Tb SATA disks and 3x 4Tb SAS Disks - can i mix SATA and SAS in the same storage pool?

Hello;

I have a Dell PowerVault MD3000, and it is showing a degraded physical disk channel error and individual physical disk - degraded path error.

The recovery guru suggests contacting a technical support representative to fix the error and do not try to fix it myself.

Any thoughts on how to proceed with fixing my issue? I am afraid to lose connection to my DAS and lose my data.

Below is the status of my physical disk channel:

I understand that VVOLS is a logical construct which exposes the SAN's underlying capabilities to VMware for granular provisioning. Here is my question. One of our newer SAN's was purchased with the license for DeDup. When using DeDup, the SAN see's the extra free space created but is not reflected in Vmware on the datastore as in more free space post dedup. With that being said, if DeDup is one of the main features we are after right now, what VALUE would adding VVOLS to the manage side of things do for us if an? We know we have alot of slack space out their and trying to making things more efficient.

SYSTEM
Windows 7 Ultimate
NTFS Boot C:\ Drive
Desktop Machine, 5.25 Inch HDD, 500 GB

BACKGROUND
Originally, I formatted the drive with two partitions of about 250 GB each.
One of the partitions is bootable with the OS on it. The other partition was for data only.

I used:  Control Panel > Admin Tools > Computer Management > Disk Management
to Remove the Data Partition.

Then I tried to Extend Volume on the Boot partition to include the now empty data partition, but there is a message saying the space is limited.
You can only extend the volume to the available space shown below because your disk cannot be converted to dynamic or the volume being extended is a boot or system volume.
The space shown is only 250 GB total. So no extension is possible using Win 7 Disk Management.

QUESTION
I need to extend the boot partition to include the space just released by the other partition. The total space of the boot partition needs to be 500 GB, the full size of the disk (except for the "Reserved System" space of about 100 MB.) Is there a tool that makes this possible?

NOTE
I will be using Clone Zilla to clone this hard drive as I have done in the past. Not sure if there is a way to extend the size of the boot partition using that tool. I do not want to clone the disk 1::1 at the moment until this is resolved.

When a friend returned my 64gb usb drive he had wiped everything off of it. I noticed that is only showed 32gb formatted and 32gb unallocated.  Using windows 10 I have tried to remove partition keeping it from using all 64gb to no avail  I cant even increase or decrease the32gb that is formatted.  Just want to get to 64gb in a fat32 format

People,

I'm having very serious issue with the VMFS access to iSCSI presented LUN from HPE Lefthand P4300G2 that is currently full due to unknown reason overnight:
LUN Full
Symptoms:
1. The VCenter VM is unable to be accessed since it is running in the VMFS datastore that is full like the above.
2. I'm unable to browse to the VMFS LUN from any ESXi servers.
3. After Rescan All, the VMFS datastore is listed as inaccessible.
4. Directly accessing the ESXi where the VCenter server VM is running with root password from Windows vSphere console was hung/cannot be accessed while the LUN is presented to the ESXi servers group.
5. Directly accessing the ESXi where the VCenter server VM is running with root password from Windows vSphere console is now possible after the LUN is unpresented or not published to the ESXi servers group.

So how can I access this VMFS datastore to erase unused VMs ?
VMware support has mentioned that this is not their problem due to the HPE iSCSI LUN is HPE Storage team issue.

Since this is running on the old HPE Lefthand P4300 G2 (4x nodes) it has already out of support.

Any help would be greatly appreciated.

Thanks
