Question about Computers & Internet

Open Question

I have an external dual HDD RAID box, the Century CRNS35EU2, (http://www.jpcentury.com/pro_con.aspx?id=P_00000024). At power on both drives appear normal displaying a steady blue LED after initialisation. During operation however, I have a flashing red LED on drive bay 1 and bay2's LED is purple. I suspect this means that the HDD in drive bay 1 is dead and requires replacing, but it could also mean that some kind of mirror rebuild is underway, (I am using RAID1 mode). There's no way to be sure since the english manual just isn't clear enough. If HDD1 needs to be replaced can I simply swap the working HDD2 into bay 1 and put a new formatted HDD into bay 2 and power up? Since bay 1 is the master drive my thought is that it will re-build the mirror automatically... but I just don't know for sure since once again the manual falls short.

SOURCE: Lacie 2big Triple 2T - Raid 1 LED's blinking

Solved! After 17 hours of blinking, the status of the 3 leds is now to fixed blue. You just have to be patient...
Note that I had only put 1GB of data on the drive. I expect that the resynchronization time is not proportionnal to the amount of data on the disk!

SOURCE: no display from projector

try resetting the lamp timer. if that doesn't work: listen for a high pitched whir when you power it on. if you don't hear it, the colorwheel needs replacing. if you do hear it and it doesn't light, the ballast is bad and needs replacing.

SOURCE: Unable to boot from HDD1 position or recreate RAID1.

you need to go into your bios and tell it to boot from the other hard drive make sure you plugged in the right wire to power it it should be the same as one used for the hard drive that works and plug it in tightly.

I need the instructions for Thermaltake BlacX ST0005U


The manufacturer page for this item is here: http://www.thermaltakeusa.com/products-model.aspx?id=C_00002058
Their support page does not provide a manual, instructions or drivers.
I suspect that is because none are needed. This is essentially an external hard drive enclosure for SATA drives which are standard. Connected via eSATA or USB.

How to choose a backup device


Hello all,

I work in data recovery and I'm always being asked what kind of backup device my customers should use. The fact is, there are a lot of choices and a lot of different situations with different answers.

Whatever device you choose for backup, remember the most important part of backing up is to always have more than one copy. Your backup device does you little good if it holds the only copy of your files.

USB Flash drives:
Pro's Cons
Most Inexpensive Easy to damage
Easiest to Transport Easy to Lose
High Compatibility Difficult to recover
Fast copy speeds

External Hard Drives:

Pro's Cons
Inexpensive Some are bulky
Higher Capacity Greater damage if dropped
Easy to transport Can be expensive to recover
High Compatibility Some require external power
Faster Copy Speeds
Easier to recover
More rugged

Secondary Hard drive(internal)

Pro's Cons
Inexpensive Not optional on most laptops
Higher Capacity Not optional on all Desktops
Fully compatible Can fail simultaneously
Fastest Copy Speeds Does not protect data if PC Stolen
Easy to Recover Requires some knowledge to install
More Rugged
Less risk of damage

NAS Box or Small Server

Pro's Cons
Higher Capacity Higher Cost
Redundancy is Optional Requires more knowledge to setup
Accessible to all PC's
on your network at once
Fast Copy Speeds
Low risk of damage
Compatible with most PC


RAID5 NAS or Server

Pro's Cons
Highest Capacity Highest Cost
Highest Redundancy Requires most knowledge to Setup
Fastest Copy Times Requires specialized equipment or software
Accessible to all PC's Most expensive to recover if failed
on your network at once
Ability to survive single
drive failures without
data loss.


Now, armed with that short list of options, let's help you decide which option best suits you. If you move around a lot, you go to school, work out of the office or travel for work a USB flash drive is often the simplest form of backup and allows you to move data between home, office or school without lugging a large drive around. we recommend these as a part of most peoples backup solution. Next you will want a more stable form of backup(harder to damage).

For your tougher backup device you will have to decided what kind of budget you have, how much data will need to be backed up and how often. If you have a great deal of data from several computers in your home or office you will likely want to use a NAS box or setup extra drive(s) in one of your existing desktops to use as a server. If you only have one or two computers or the budget just won't cover a RAID or NAS solutions you can simply purchase an external USB or eSATA hard drive, usually less than $100. This can be moved between computers and used for backing up.

Now remember to Sync your data. This means anything you update or create while away that is saved on your USB flash needs to be copied into your computer and your computer needs to be backed up onto the external drive or server.
For more information on backing up, verifying backups and different types of backup devices, visit my blog at http://www.aitsavemyfiles.com/armor-itrecoveryblog.php or search through the other tips available here on FixYa.

WHAT POWER SUPPLY RATING DO I NEED TO RUN A A74 ML-K MOTHER BOARD WITH usb keyboard mouse printer SD Card reader


Hi, the download site for your mainboard is here:

http://www.foxconnchannel.com/product/motherboards/detail_spec.aspx?ID=en-us0000491

I would say 400 watts.
It depends how big your cpu is. 400 watts is ok
with a dual core.
If you planning to add a bigger cpu or a graphic card
you must have at least 600 watts psu.

To raid, or not to raid,? that is the question............


Hi,

Always a good question,

For #1

Always a good idea to mirror your OS drive for quick recovery. So yes I would use 40GB of the velociraptor for a mirror. However if your board supports it I would actually suggest you would be better served for your dollar to buy some 500GB+ WD greens or seagate 7200.12's(do NOT buy 7200.11) then set them up as raid5, frankly you'll get redundancy and speed, with more space. 4 Greens will perform as well as three VRs and cost less.

I currently run two Greens and 2 7200.12's on my home server and the 7 rating is 7.6 for my HDD and I've got 4.2TB of space for under $500.

I mentions some of the pro's and cons in detail on my blog last week Pro's and Cons.

Hope this helps,

Chris

The SimpleTech user guide (http://www.simpletech.com/support/guides/user-guides/Duo-Pro-User-Guide-11012007.pdf) does not correctly describe the reset sequence to switch the RAID level.
The correct reset steps, I learned after talking to technical support, are:
Power down
Depress (and hold) reset button
Power up
Wait 10 seconds
Release reset button
