comment SSD head / cylinder / cluster details
I'm slightly skeptical this is going to work any better than the SATA-IDE adapter due to the necessity of knowing what values are needed to spoof the platter geometry for manual entry. Checking packaging images for 3 different brands on Amazon I didn't see those values anywhere; which'd make providing them to the BIOS difficult. For cost reasons though it's probably worth trying before shelling out of an industrial drive as suggested by ewwhite. Neither source he linked to had readily visible prices, which is not a good sign.

comment Email going to a user at a similar domain name
@dunxd That was certainly going above and beyond the call of duty. Did you find out how the error happened? Fat fingers?

comment Using Y power cables in a datacenter
Are server PSUs optimized for a different point on the load curve than consumer ones? For the latter peak efficiency is normally at ~50% and falls off on either side of that point. Ex test #3 here is the 50% point. jonnyguru.com/… Similar results were shown for both of the other reviews at the top of the main page; and on most if not all of the reviews I've seen of quality PSUs.

If you can't get them to do something you need leave. You're not being paid enough to ruin your health.

comment Any reason not to enable DoS Defense in my router?
"If implemented correctly" isn't assured; especially on consumer grade hardware. The Netgear router I was using at home several years ago had a major bug in it's DOS filter. It was possible to send a single packet with malformed data that would cause DOS filter to crash and take the router down with it.

comment Can a RAID 4 disk setup crash if only 1 hard disk fails?
@longneck You're right; I was thinking of raid 2.

comment Can a RAID 4 disk setup crash if only 1 hard disk fails?
RAID4 should be RAID3. RAID3 is byte striping with parity; RAID4 was an ECC implementation needing a huge number of drives that AFAIK was never implemented.

comment Server Rack vs. Server in PC “Towers”
If your supposition about them largely relying on passive cooling is correct, typical towers do have an advantage in having more room for large heatsinks than rackmount servers where making them as thin as possible to maximize rack density is a major design factor.

comment Balancing RAM when using multiple CPUs
@DavidSchwartz are server chips somehow different in regards to memory amounts on each channel? I recall regularly seeing imbalanced memory amounts on consumer LGA1366 systems offered in retail several years ago; and at the time was told the only penalty would be for the portion of the total not spread across all 3 channels. ex installing 4-2-2gb would give 6gb at 3 channel performance and 2gb at single channel.

comment NAS device claims drive in a RAID is degraded but S.M.A.R.T. says it is fine
Microsoft research has found (via analysis from windows error reporting) that the odds of a second OS crash due to an HD error after a first is 1 in 3.5 for computers that have reported at least 30 days of system uptime. If you have a second crash the odds of a third are 1 in 1.7. Hardware failure is rarely a random one off event; if you care about the data on your system you should immediately replace the drive after the first error. research.microsoft.com/apps/pubs/default.aspx?id=144888

comment How can I hide a Virtual Machine in the Hyper-V Manager, so that only administrators can see it?
The only plausible business case I can see for that sort of access would be to let users create vms for test/dev/etc use without needing to go through an admin (being able to do this would make my life easier at times). However, those VMs should be isolated on separate hardware and a separate admin console so that the developers/etc can't accidentally screw up any production systems.

comment Server room in shipping containers
Does Google actually have sysadmins working inside the containers, or do they use them similarly to how MS does? I've read that MS builds its datacenters by installing pre-built shipping containers of servers as sealed units without any internally serviceable parts (the entire container is swapped out as a unit when it gets too old or has too many dead servers) and only jacks power/ethernet/cooling into the exterior.

comment Should I reinstall my production server from 32 bit to 64 bit if it has 16GB of RAM?
IIRC you can implement PAE at the application level as well; and that it used to be fairly common among DBs and other memory hungry server apps back before x86-64 hardware was common. However with it now ubiquitous PAE code branches are being deprecated/abandoned due to lack of use sufficient to justify continued development work.

comment Good reasons to keep 32-bit Microsoft Windows desktop OSes
@Xeoncross It's not just older Atom systems. Intel's current D2500/2700 desktop Atoms have a powerVR GPU and only have win32 drivers.
