Walmart online has external hard drive cases for $20-30 if you've got
spare drives. My friend said some of the ones at walmart don't last
long so you'd have to check reviews if you go that route. It doesn't
usualy trash the drive though.
Watch out for those little Western Digital usb powered drives. They
had a bad reputation of dying and data loss.
I don't know about the newer ones.

I've had superior life and performance from the Iomega "E-go" USB drives.
The standard model is 500GB for $89.95 new, and $49.95 "refurbished"
(which I never trust. Refurbished means "put in a new package for the
customer to test."
The E-go series incorporates "drop guard" technology, and ours have been
dropped many times from desktop height to a hard floor without causing

Sure, but those SOBs demand crazy things like credit cards or paypal

Two? Oh, I get it. Two used ones at $50 each instead of one new one

IDE laptop drives for $10-15 and they include all the power adapters
and cables you need, "the magic matchbox". If you were to buy the
power adapter and cables separately, they'd run several times what the
boxed adapter costs. I've got a local Microcenter I get stuff from,
www.microcenter.com, Kingwin is what's on sale now. I've also bought
external USB cases for as little as $10 there. Just depends on what
you've got for spare drives. I usually run image backups onto the
bare nekkid drive laying there with the USB adapter on it. There are
silicone boots that can be had to jacket the drives in storage, makes
it easier to stack them up. Leaves the connectors free, too. Some of
the USB adapters can handle PATA and SATA drives at the same time,
makes system swapping easier. Lately, I've been making use of eSATA,
much faster than USB, but one cable costs as much or more than one of
the USB adapters.

All mine says is "Made in China". It connects PATA, SATA and laptop
drives to USB. It came from the second hand computer store where I

Thats the one I have, and its been working just fine for over 2 years.
And at 20 bucks, you can't go wrong.
One thing to remember, alot of times the front usb ports on a computer
do not have enough 'umph' to run a hdd properly. So the best thing is
to plug it in to the back of the computer (on the usb ports that are
directly connected to the mobo)
Michael A. Terrell
Where do you think those front panel USB ports go?
--

tnik
Yes, I know they are connected to the mobo, but from experience I can
tell you that the power coming from the usb ports directly on the mobo
is greater than the power coming from the usb ports on the front of the
case. There is enough voltage drop just from the wires to make a laptop
hdd not want to spin up enough.
Now using the above connector with a regular SATA/IDE hdd works just
fine because you actually hook up external power to it.

Same here, I bought a drive case for ~$15 from Buy.com and slipped a spare
80 gig drive in it for back up. Also the wife had a Western Digital "Book"
external drive that died. I tore it apart, and it had a normal HD in it. I
bought a case for it too and we still use it back up too.
One other deal I picked up off Buy.com is a do-dad that will plug into any
HD and you can plug into the USB port and pull the info off the drive. That
was only $15 or so too. Saved data from a couple computers with it already.
I had a laptop that died, it would not power up and had some info on the
drive I really wanted, plus pulled info off a drive a friend brought over
from a crashed desktop. Well worth the bucks if you have a crashed computer
that you want info off of!

Getting anything shipped for much less than $10 is getting pretty hard these

The USB port supplies a maximum of 500ma per port at 5 volts. The wire
is mabee a foot long - so total 2 feet of conductor. SAY it is 28
guage. Resistance is 212 ohms per KM, or 0.0054359 ohms per inch 0r
roughly 0.13 ohms for the 2 foot assembly. Voltage drop under full
load is 0.13X.500= 0.065 volts.
That's 32 milliwats of power loss.
Totally inconsequential in my books.

If you're REALLY lucky, the MB USB ports will supply half an amp
each. The VIA chipsets aren't in compliance with the spec, NVIDIA is
marginal, the only MBs I've had good luck with USB-powered accessories
are ones with Intel chipsets and they're the ones that originated the
spec. If it's not an Intel-based MB, I get a separate USB port card
with an NEC chipset on it, hook the case USB sockets to that and
disable the MB ports. Items like the larger capacity portable USB
hard drives and port-powered scanners just can't get enough juice out
of the wimpy ports, have fought the battle many times. USB cards with
other make chipsets aren't compliant, either. Some hubs won't make
the grade, even with external wall warts. The consequences of pulling
more current than the port can supply range from the machine shutting
itself off to the port shutting off until reboot to the OS just not
recognizing the device when it's plugged in. With USB-powered hard
drives, marginal current supply will result in the drive dropping off
and adding back in repeatedly, if it happens while a file is being
moved, the file can disappear and the drive can go corrupt. If all
you use the USB ports for is the occasional flash drive and mouse and
keyboard use, you'll not have a problem.
As far as front vs. rear ports, I've noticed the same on some
machines, sometimes the front ports are the early 1.2 spec and only
the rears are 2.0. Depends on how cheap the OEM was. You'd think by
now that everyone would be putting in 2.0, at least, but there's still
1.2 devices and ports being sold on new equipment. Must be a bunch of
1.2 interface chips in some Taiwan warehouse somewhere and they need
to dump them somehow, particualrly now that v3 devices are out now.
I've also found there's a vast difference in the cables used to link
devices up to ports and hubs, too. Some have enormous voltage drops,
sometimes just swapping the cable enables the device to work. Has no
relation to price of the cable, either.

A lot has been pulled off the SCSI spec into SATA drives, including
the command set. Very easy to make an adapter that hooks a SATA drive
to a SCSI bus. If you go back far enough, the original PC drives had
to have CPU intervention for every read or write, this survives as the
PIO default controller mode on most MBs. SCSI by-passed this by
having a relatively cheap adapter in the machine and the smarts on the
drive. It also used DMA for transfers, so the CPU wasn't waiting
around for the drive and controller to deliver the goods. Somebody
thought this was a good idea for consumer drives, so IDE was born.
SCSI was at least 5 times the cost of a similar capacity IDE drive, so
was seldom seen in consumer-grade equipment. Still had the edge in
performance, so was used a lot in mini-computers and high-end
servers. And it wasn't limited to just hard drives, the spec allowed
virtually any peripheral to connect. It's gone through 5 or 6
iterations, each time the transfer rate improved and usually the bus
got wider. Latest is the serial-attached SCSI and there's one type
that uses fiber for data transfer. Since demand is lower for these
units, prices are a lot higher than for SATA drives. I think there
are also patent considerations, one reason SCSI hardware has always
been higher priced than IDE or SATA stuff. One of the nifty features
is that as long as the electrical interface matches, you can hook up
older stuff on newer adapters or newer stuff on older adapters. You
aren't going to get Ferrari performance out of Model Ts, but at least
the stuff works, usually. Another feature was the longer length that
the cabling could be, the differential-type interface allowed a really
long cable, necessary for large external equipment. IDE was limited
to 18" max, pretty much meant the drive had to be in the box.
I used to run a lot of SCSI drives and peripherals, the Microtek
scanner with the SCSI interface is still the fastest I've ever used.
I had 16 drives running on the one machine at one time. If I needed
more space, I could just add another to the string. Drives were cheap
on the surplus market as long as I didn't insist on having the latest
and largest. SATA dropped to the point where it was cheaper and about
the same performance, more to the point, the available drive sizes
were a lot larger for a lot less cash. So I folded the drive strings
down to 4 SATAs and an IDE boot drive. Still have a SCSI controller
in there but it doesn't get much play.

If you say so, but I've never seen it and I work on a LOT of
computers. I have seen duty and corroded front panel connectors, but
they will still supply the full 2.5 watts, if needed. I also see more
broken connectors on the front, from abuse. When replaced, they work to
spec.

MFM drives are older and used a different interface. They are mostly
from the XT to 386 era. They are too slow for a lot of newer
motherboards to deal with.
If the MFM drives were used on XT computers you need the same model
HDD controler board to read them. 286 & later were 16 bit, and used a
standard setup.

is there something you need recovered from the MFM drives? I had a
working 286 system in storage for data recovery. I haven't fired it up
in the last five years or so, but it might still work.

I should have both 8 & 16 bit controller cards. The code was G0500,
or something like that. I haven't had to low level format a ST-506 type
drive in over 10 years. I still have the information, somewhere. I
know it's in my copy of the 'PC Pocket Reference'. There is a lot of
useful information packed into that tiny book.
> What protocol was next, and replaced MFM? I'm sure it wasn't IDE yet.
RLL followed MFM. When they moved the controller to the drive it
converted a RLL drive into an IDE drive. I think I still have one 8 bit
IDE drive that works, but I haven't used it in over 10 years.

RLL was next.
The hot setup was to get a winchester controller.
With it you could configure a drive to be up to 20% larger than it actualy
was.
Much more than 20% and reliability suffered.

RLL gave you 50% more storage than the same drive in MFM. Not all
MFM drives were usable with RLL controllers though.

Im sure Ive got RLL and MFM drives kicking around if anyone wants them.

RLL - still St506 and a lot of MFM drives worked as RLL drives with a
50% increase in capacity.
Just had to re low-level them on the new controller.

RLL and MFM were encoding methods. IDE drives could be MFM or RLL or many
other recording schemes. IDE just integrated the drive electronics in to
the drive. My boss at a disk drive controller company, in 1980, left the
company and went to work for Jim Patterson, founder of Maxtor, and a former
VP of the company we worked for . Richard said lets put the drive
electronics inside the drive. Maxtor formed Plus Systems and Richard
fathered the Hard Card. First drive with the controller inside the drive,
as opposed to a separate controller / data separator.
