No I have blocked out all recollection of ever having two on a striped RAID array :brickwall:

oh you poor boy.

Almost as bad as having Toshiba drives in a stripped array in Sony Vaio laptop (I wish that client had stopped buying those damn things - most of wound up with drive failures from the damn Toshiba drives)

Sufficed to say I've never that big a fan of Raid-1 stripe arrays.

Hey guys, I'm planing to buy a 85W MagSafe1 adapter though Kijiji ( just the wall adapter with no extension cord). I sill have the original long extension cord for my old Mac Book pro. Will it still physically connect to the more modern 85W adapter? I'm thinking it should since the old extension cord is also for 85W. Only difference is my old charger had a "T" style connection and the new one will be "L" style. I don't think that should matter though when it comes to connecting it to the original extension cord.

IBM's largest drives were 14" behemoths, they were not for PC's though, as for old MFM drives, a lot came in 5'25" FULL height, that is like stacking 2 CD-roms on top of eachother, 5.25" half height aka one CD-ROM in height were also very common like the Seagate ST-225

Quantum's Bigfoot drives were an attempt to cram as much space as possible into one drive with the most neanderthal and cheap technology possible, they were ex..cep..tio..nal...ly.. slooooooooooow... with platters that big access time was measured in years.. :p

And the weight man, the weight - they were heavy suckers!!!

don't forget they did it using 5.25" form factor at a time when the rest of the world was pretty much set on the 3.5" form factor.
 
I've got several 5.25" full height drives, a Seagate ST-412 10 Mb drive, this is the oldest drive I have and it still works, this one is moderately heavy, the next one is a much heavier Seagate ST-4026 which is the first one with voice coil actuators, this drive, gigantic as it is holds 20 Mb, the largest, heaviest and most special sounding drive I have is the 5 platter 5'25" full height 80 Mb Seagate 4096 also a voice coil drive and it sounds like this:

That brings back a few memories :)
 
Old MFM drives had character, in the past you could literally identify a drive by the sounds it made, this is not always good.. Seagate Barracuda 2.1 Gb 7200 RPM SCSI drives.. yes, you recognise them.. by the angry double frequency SCREEEEEEEEEEIiiiiiiiiiiiiIIIIIIIIIIIIiiiiiiiiIIIIiiiii!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! and no, they're not broken or worn out or whatever, they are in tip top shape, this is just how they sound, I think they deliberately made them spin up as slow as they do, OMG.. OMG.. OMG.. can't get worse.. OMG!!?? ARGH? and when they reach the desired RPM you get a soft "clink" from the heads being released, they were quite fast but not fast enough to prevent a nervous breakdown before you finished installing NT on them.. :ack:

That was the quantum bigfoot. Similar in one regard though. They made a hell of a noise!

I once had a 6 GB Quantum Bigfoot. That thing was enormous, and I had packed it inside a Packard Bell, because it's what a customer wanted, and they wouldn't accept any other hard drive as an option. You could hear the metal screeching as I shoved it down in there and tried to secure it. :lol:
 
They were slow but as far as I know very reliable, low data density for platters that size and chunky mechanics made them sturdy, sequencial read was acceptable access time not... :vulcan:
 
[An Old Fart Reminisces] Thirty years ago I remember 512 MB drives so big and heavy that four adult males were required to carry one up a flight of stairs. Nowadays, a 512 MB memory stick has a laughably small capacity. [/An Old Fart Reminisces]
 
Sounds like one of those disk packs for IBM mainframes, they were the size of a washing machine.. 512 Mb sounds about right.. :biggrin:

Pff, small stuff. ;)

^^ That is what I was talking about!

And the world's most expensive harddrive, say, got a quarter of a million bucks lying around?

How about a £1million dollar supercomputer?

At the time the video was made it was worth more as scrap than parts (not to mention using £115 (at 2011 prices) of electricity a day!!!!!

And then there's stuff originally worth 10s of $1000s into the millions that winds up in some guy's garage

Yeah, by the mid 80s, increases in storage density had already started kicking in but the kit was still very cumbersome by today's standards. The compact terabyte and larger drives of today seemed like an almost unobtainable fantasy. Of course, there's still plenty more room available at the bottom.

Computers everywhere.. VAX's PDP's PC's and everything inbetween.

In other news, finally got my retro build to work, its a Barton core Athlon 2800+ running at a neat 2083Mhz it has 512 Mb DDR1 RAM, the board the Athlon came on seems to be dead.. it switches on, will work for a while and then all the sudden the whole machine switches off, I've found a replacement board in my pile of stuff, Asrock K7S41GX, micro atx and one of the last Athlon boards made IIRC, the good is that it works well with the chip, also the caps on this thing are high quality. http://www.asrock.com/mb/sis/k7s41gx/
Storage: 160 Gb HDD, DVD-ROM, DVD-Writer all PATA, luckily I had rounded cables lying around, of course it has a Floppy drive, 1.44 Mb baby! :biggrin:

Graphics: I originally had a Geforce 6800 AGP for this thing but the fan of that card is dead... so now its a Geforce 6200 a tad slower but its cooler is passive so no fan, no noise, sound: Creative Labs Audigy II, I actually don't know how I got hold on that one, but it's working, for fun I added a 56k modem.. :hugegrin:
Its all housed in a beige Chieftec casing which is build like a tank, the PSU is a Asus Atlas 450 watt which was made by Delta so high quality, low ripple.

OS: Windows 2000 Pro I used Win2k until M$ dropped support for it and delayed installing XP for many months afterwards..
Updating Win2K: I always use the unofficial Windows Service pack 5, this holds almost all updates Win2K ever had, some are missing but the bulk you've got with this one, you will have to look around online for it, MajorGeeks has a copy on it and people are still working to improve the service pack.
