Title: WTB: 50 pin SCSI harddrives
Post by: doctorq on February 26, 2011, 09:40:04 PM
I'm on the lookout for a couple of 50 pin SCSI drives, in the range of a couple of 100 MBs and up to 3-4 GB.

Anyone have some laying around??

yea I have a bunch of them at lest 5 or 6 ranging from 4 gigs to 20 plus gigs I think drop me a email calkster1@hotmail.com I'll send them to ya if in the US

Are chaps are aware that any Scsi drives can be connected to 50pin connectors regardless of the of drives connector ?

80 pin sca U160/U320 drives can be used, your not restricted to just 50 pin physical. There are plenty of Ex-U160 9gb/18gb drives out there.

I have box with around 200 in.(Sorry not for sale as they contain patient data and are due for crushing) :(

Edit: Its morning here, just forgot, there is also scsi 3/wide connectors (68pin connectors as well!)

I'm aware of all the adapters available, but I want ordinary 50 pin drives. The reason for this is that the drives needs to be mounted on Zorro hardcards, and even with the smallest adapter I have around here, a 68 pin harddrive doesn't fit very well on the hardcards.

Coolio, if for resale understandable. Personal taste really. I wouldn't consider putting a drive back on a hard card as they get way to hot to be hanging around on a piece of pcb. In essence thats why they disappeared from hard cards in the real world, as the failure rate was massive. Good case mount or even external case would be preferable for reliable operation.

Not necessarily, an A2000 with a GVP hardcard will be cool enough. Going external is a bit extreme.

Ive got a few boxes full of assorted old drives (many scsi) so its more than likely some are 50 pin. If youre willing to pay postage (Im in Australia) you can have them if you like. Just let me know if youre interested (or not) and I'll check out what's there.

I usually remove the DF1 drive and mount the harddrive there in an A2000.

I had a couple of 68 pin drives (identical) with an adaptor, but I couldn't get them to work. I tried several utilities to format them but kept getting messages like "Drive not supported".  I know some will work, but others seem a little picky. I got 2 50 pin drives from LoadWB, they worked perfectly.

If heat is a real issue with hard-cards, you could probably make a little space between the drive and the card (for air circulation beneath) by using standoff bolts like this:

(http://s4.postimage.org/2xplhr6qs/3849031647_206de35fd9.jpg) (http://postimage.org/image/2xplhr6qs/)

They have a female threaded hole in the top you can't see.  So these brass standoffs screw into the harddrive, then harddrive is positioned on the card and the heads of these standoffs lined up with the bolt holes in the hardcard, then the bolts normally used to mount the harddrive to the hardcard go into the heads of these standoffs.

I use a 36 gig scsi Seagate Cheetah Model # ST336706LC in my a3k with  the 80 pin adapter. Its be working great since I got it around october..  I can only make 4 gig partition's on it. I need a high byte terminator  on it... watching for 1 cheap.  I have three 4 gig partition's on it and  hasn't failed yet ( told it I would get errors). So not doing anything  but whload gaming on it for now. The adapters do work but I think some  80 pin hd's are picky. I have a 9 gig scsi 80 pin out of a compaq and  can't get it to work yet.  too bad. I think to many jumpers and maybe  some conflict's maybe.

A lot the issues with scsi are around the ID and termination. Since Scsi old style is 0-15 and later had 64 I believe (7 bit 8 bit) addressing, as long as you terminate the bus, most scsi drive should work,as the Amiga doesn't care what scsi drive you use. Its a good idea to a pc handy with an adaptec controller to give it a good format and change any drive parameters.

I have about 5 or so in storage, they worked fine years ago... Went from a couple of hundred mb to 4 gigs.  If your really interested let me know and I can pull them out and look.

Concerning the converter to 68 pin scsi, it works fine here.   I have a 3000 with a 10k Quantum Atlas and it works great.  I don't use the 3k scsi, I'm using a warp engine 3040 for the SCSI though with PFS 3 (Not sure if that would make a difference?)...

I ordered the converter from a local computer store years ago, I can see what brand it was and if it's still in the market...

@matt3k

Thanks, obviously I'm interested, so please get back to me on the sizes you have, how many you have, and how much postage will be.

@all

This thread is about 50 pins drives specifically, and for a reason. I am aware of all the other drive types available and all the adapters available as I have them already. I want to use the hard cards as the designers intended, which means mounting a 50 pin drive on the hard card. A 68 pin drive with adapter works fine with the controller, but doesn't fit 100%, as the adapter will be forced upwards by the cable.

You guys don't do this?

Heck, I'd wipe military drives with it all the time.

I had a 2091 on which I mounted an 80-pin 4GB drive.  I was able to use the cable without issue since the SCA-to-50 adapter was low profile and the 50-pin port was at the top of the drive.  This caused no stress on the cable, drive, or connectors.

Other than that, too bad you did not need these drives before I sent all mine to the dump.  Sad, too... I put them up for the cost of shipping alone, and no one wanted them.

Yeah, that's though luck, but I'm confident that something will show up :-)

Now we know where the wiki leaks came from. ;)

Basically its a trust issue. Shredded and crushed disks can't be read. Wiped disks end up on the "black market" not wiped ! Especially when some one tries to sell the idea of wiped disks or "we'll" wipe them for you and don't!

Dead/Crushed and shredded disks don't haunt governments!

I could use a couple of 4gb drives.... 50 pin though. I have some 8 and 16gb 80 pin drives if anyone wants to swap...

Well, that is true, but there is a big difference between someone claiming to have wiped them but not and someone actually sitting down and wiping them :).  When the drives are actually wiped, they are fine for reuse.

Talk about scary, I'm on the hunt for two 4GB 50PIN SCSI drives, or 68PIN... aslong as they are around 4GB, need it for an A590.

yeah, because its so hard to write a simple code yourself that wipes?
or simply use different systems, one for wiping, other for verifying its wiped?
heck, you could fill it with bogus data.
shredding them seems wasteful. besides, its probably not environment friendly.

Hi doc,

I pull them out of storage.  I won't be able to test them until at least next week.  Perhaps we can trade some amiga hardware (3000 parts or cards perhaps)?  Or amiga educational software (original with manuals).

If I can get one test formated and burned in for a day or so then I'll call it good...

Do you live in the US?
