Laptop questions [Jun. 13th, 2001|06:41 pm]
Brad Fitzpatrick
Two laptop questions.

1) I need a power adapter for my car. Does this look good? Anybody know of better/cheaper ones? This looks neat, but I understand that DC --> AC inverters aren't terribly efficient. Would it be safe to use one for a prolonged period of time while the car is running? I assume the alternator would keep up. Who knows electrical stuff?

2) Anybody have a copy of Partition Magic I could borrow? I need to resize my laptop's Win2K NTFS partition down so I could make space for Linux. I think I'm going to make a big ext2 partition for mp3s so I could use Explore2fs to access them from Windows, then the rest will be ReiserFS.

Update: DC to AC to DC is stupid. Getting the one Sherm suggested at Office Depot. And Partition Magic I can get free from school.

Available at Office Depot! They're open until 9! It's in stock! There's a McDonalds next door!

I'm off!

You ditched me for a run today. You said you'd see me again today.

Well, I bought it, but now that I look here I see it won't work (Dell Inspiron 8000). I got part #PA350U, the only one they had... Office Depot doesn't have other tips.

Oh well....

Alternator should keep up with anything you do while the car is running.

AC wave theory sucks, you don't want to go there with the DC->AC thing

If you get a fairly good inverter, they're actually not that bad.

Good friend of mine has one in his truck...goes fishing on the weekends, takes his laptop to watch DVDs :P.

But, it would be more intelligent on the whole to just get a good adapter, considering that the power cables that come with your laptop do AC->DC anyway.

Actually if you buy a *good* AC inverter, you find tons of uses for it (most emergency: "oh crap my dig camera has no batteries, and im on the car-ride there")

Dont buy something that has a proprietory plug on it, that way your limited in what you can use it too.. You cant go wrong with generic 3 pronged plug on it..

I can send you PM if you want, don't know if you're looking for someone local with a CD, though :)

Have you used Explore2fs? It was painfully slow when I tried it.

You might consider SGI's XFS too (oss.sgi.com/projects/xfs); the only problem is that SGI's patches lag a few weeks behind the 2.4.x series releases.

No, I haven't .... I haven't had Windows and Linux on the same machine in years. Suck. Well... I'll try it out and let you know if it has improved any.

fat32 for mp3's?

If you're just looking for a partition to dump mp3's on, you could always create a third partition, and make it fat32. That way both Win2k and Linux will be able to access it fine.

On the other hand, I know I remember seeing a native win32 filesystem driver for ext2, allowing Windows to see and view it as any other filesystem. And I think it might have been available for free.

I'll check my bookmarks when I get to work tomorrow, and see if I still have the URL, if you want it.

Re: fat32 for mp3's?

My mp3 collection uses a lot of symlinks, though (for categorization of artists and albums by genre). FAT32 can't do symlinks.

I remember seeing that driver, too, but I think it was only for Win 95.

Re: fat32 for mp3's?

Does that compatibility filesystem which creates hidden files for the permissions (umsdos?) support symlinks? I don't know, I've not actually ever used it or had the need for it... but something is nagging me from the back of my memory.

Failing that, can't linux mount ntfs read-only or something? (I've never had to do that either!)

Re: fat32 for mp3's?

Hrm. . . I found a few different things.

I found a free NT driver for ext2, but it's in beta, and not gonna get any better. It appears the guy sold it to a company, who then polished it, packaged it, and is selling it. Which is another alternative, but they're wanting $30 for the read/write version.

You can download the last free version from at least the second download site listed

It's rar compressed, which is mildly annoying, but it works fairly well.

I *know* there's another one out there somewhere, 'cause the one I mentioned above isn't the one I remember seeing, but I haven't been able to find it.

now i realize that you are a power user Brad, but christ almighty, if you got the good battery that Dell offers with the 8000 (which i'm guessing you did), it lasts about a good 3 hours, and that's if you're really working to drain the battery (i've watched entire films on mine and still had nearly half the juice left). or is this pre-planning for the previously mentioned road trip?

Yeah, I'm gonna be on the road for 3 or 4 days...

I did an extra battery for normal use, but this isn't normal. :)
