this question makes me feel old

Q: Which kind of hard disk is this? (picture attached)

My girlfriend has an old laptop-drive she wants me to grab data from. I want to buy a usb-adapter for it, but I have no clue as to which kind of disk this is. There are no text printed on the drive except from "Made in China" and "F4". The hard drive's size is 7 cm x 9,5 cm excluding the pins. I...

Anyone wanna buy like... 1000 HDD platters?

@Bob Yeah, pretty sure that's PATA. I remember fiddling with those annoying master/slave jumpers back then...

Had a bit of a scare earlier today. I was fiddling with a stripped USB cable, using it in conjunction with a high-amperage supply to power a high-drain load. The cable was acting up, intermittently dropping power for whatever reason. About 20 seconds in, I noticed smoke and freaked out before I saw that part of the wire insulation was melting. Needless to say, I immediately disconnected the wire and threw it out.

It was a very cheap, low-quality cable that was never meant to handle 2+ amps of current. Before I cut off the Micro-B end and stripped it, devices never really were able to draw more than 500 mA or so through it.

Apparently, some strands of the wire broke, and when it did manage to connect, the resistance was so high that it melted the insulation where the wire was broken.

That sounds like fun! I accidentally overcharge a li-on battery the other day to the point it started bloating.

Hmm... If I call one Powershell script from another, do they have their own variable scopes?

By the timestamp and size of my output files, you can tell the exact time I broke my script, and when I found and fixed the bug I introduced.

And also how many tries it took me to release what I had done.

@MichaelFrank Yes, unless you dot-source the call

There are a bunch of scope prefixes you can use, though, if you want to control things more finely

Michael Frank

Okay, maybe you can help then... I have a script that'll query a computer for it's local groups and their members, SIDs, etc.

I'm trying to call it from another script, but it doesn't seem to fire off. I'm not getting any errors though.

Ben N

Sprinkling some Write-Host calls around should help you figure out where it's running to

Alternatively I hear the ISE has some debugging features

Michael Frank

Okay, so it doesn't even launch the other script...

Ben N

Can you share the parts that do the launching?

Michael Frank

& C:\Powershell\Get-LocalGroup.ps1 -Computername $Path.Split("\")[2]

Ben N

3:28 AM

Hmm, maybe try it without the & operator

Michael Frank

Still doesn't fire the write-host that's inside Get-LocalGroup.ps1.

Could it be because it's written as a function?

Ben N

And you're sure it's reaching the call line?

@MichaelFrank Yeeeeeep

Executing a function declaration will just define the function, not run it

Michael Frank

oh. derp. Of course.

Ben N

Heh, that's tripped me up too

Michael Frank

In that case, I dotsource and be careful of variable names....

Ben N

Alternatively you could leave it as a function, dot-source the other script at the beginning of the main one, then invoke the function instead of calling the script

Michael Frank

:))))))

I feel like Anakin Skywalker right now.

Michael Frank

3:47 AM

...well, kind of. It's calling the script, but I feel like there's something else going wrong now.

Helloooooo

I finally got to 80 flags on Super Users! :)

@Rahul2001 Hey!

Rahul2001

Okay, so, this is weird

I have an FAT32 disk that I would like to use to liveboot SUSE

But the ISO file is 4.08 GB in size

So I cannot copy it onto the drive?

My day is drawing to a close, but some food for thought: tomshardware.com/reviews/intel-optane-raid-report,5060.html

> The array delivers a staggering 3,500 MB/s of sequential read performance from QD1 to 128!

However, it does seem to come at the cost of sequential write speed.

For read-centric workloads, it's abundantly clear 3D XPoint, at least in its consumer Optane Memory form, is lightning fast.

Write performance looks as if it's artificially limited given what the P4800X is capable of doing, but I suspect the real limiting factor is the controller having only one channel to the underlying 3D XPoint memory.

> You can't double click applications fast enough to place a heavy enough load on the device to reach high queue depths.

lol

> What steady-state conditions, Optane asks? It's as if Optane taunts NAND with its performance, and consistency is also impressive. Optane is a natural for RAID.

lol

This, my folks, is the future of high-performance storage.

Again, though, limited capacity and high cost means a reasonably-priced high-capacity 3D XPoint storage solution is not exactly happening soon. It'll be an enterprise/workstation/super-enthusiast product for a while.

@Rahul2001 You can try. It'll probably fail.

Depends which GB you're using.

bwDraco

@Bob Probably 4.08 GiB (the value reported by Windows). It will not fit.

...night.

Journeyman Geek

also depends if the tools unpacks the ISO

Rufus would do that
