Given that I am building a home computer from scratch and I have several components (MB, CPU, HDD, Video, Sound, etc) which have specific power requirements, is there a formula for me to calculate the size/capacity of the Power Supply I will need? I want to be able to expand the setup later on also……
Case:The client said that the mobile hard disk was placed on the table. When he took things, he accidentally touched it and fell from the table to the ground.After picking it up, you can identify it on the computer, but only one area can be recognized. There are three districts.And when copying the data, I…
Case:The RAID5 No. 0 disk of 4 plates makes the final line, and the hard disk does not recognize after the launch 1 and 2 is forced to be launched. Solution:After the engineer’s test, the No. 0 plate is OK, and the magnetic head of the No. 1 and 2 is aging. There is a…
Case:Mr. Wang’s database was suspicious. The company’s technicians were not good at database suspicious data recovery, so they contacted the data recovery center engineer. After explaining the situation, the engineer preliminarily judged to give a conclusion.Recovery Solution:After receiving it, the engineer started operation. Through professional technology and operation experience, the lost data quickly returned to…
I have a question. I have been experiencing delays when controlling my smart-home devices when everyone is home and using the internet. The internet is not slow, (300Mbps) but I think the one router doesn’t cope well with the 25 devices we have concurrently connected. My thought was to separate them in another Subnet, with…
HDD Printed circuit board (PCB) with board number 100389148 is usually used on these Seagate hard disk drives: ST3160212A, 5LS, WU, PN 9BD012-065, FW 3.AAE, Seagate 160GB IDE 3.5 Hard Drive; ST3120213A, 5LS, WU, PN 9BD01C-302, FW 3.AAD, Seagate 120GB IDE 3.5 Hard Drive; ST3802110A, 4LR, TK, PN 9BD011-033, FW 3.ADH, Seagate 80GB IDE 3.5…
Case:On the Apple IMAC computer, the hard disk responds slowly. If you can’t enter the system, you need data to be sentenced to the death penalty. Solution:After removing the hard disk, connect to our professional equipment to detect, the hard disk firmware responds slowly, and there are a lot of bad sectors. After repairing the…
Usable storage capacity
Disk array capacity that is usable for data storage (vs. for mirroring or parity data). For example, under mirroring (RAID 1 and 0/1), usable storage remains a constant fifty percent (half of storage is always used for redundancy). This is in contrast to other RAID levels such as RAID 5, in which usable storage capacity is determined by the formula of “n-1”. “n” is the total number of disk drives and “1” is the number of disks worth of capacity used for parity (redundancy) overhead. So, as the number of disks in the array grows, the usable storage capacity percentage increases in relation to parity (redundancy) information.
My work place intercepts SSL connections, looks at their contents, and then passes the data to and from my machine and remote hosts – a kind of man-in-the-middle attack. This is not uncommon in corporate or enterprise environments. Now I have a virtual machine running on my computer. The virtual machine does not have the…
Case:Play the mobile phone for children, accidentally delete the text messages and photos inside, and some contact information, which is very important to customers. Solution:Data recovery engineers first conducted a fault analysis to check whether there were secondary damage, and then extracted the underlying code through professional data recovery devices. Finally, the file system was…
