SD Card to IDE Adapter in 380XD

[Paul Pennington]

I picked up the subject device on eBay (item number 180299831698). This one is designed for notebooks and fits nicely in the space where the hard drive was. I put a 8GB SDHD card in it.

It works, I can read and write files to it, but won't boot.
This 380XD is a 2635-FAU, and I updated it to the latest BIOS.

I tried these three so far: MSDOS 6.22, Windows 98SE, and Partition Magic. In each case, the unit booted from floppy, and the FDISK and format operations did not show any errors (the MSDOS disk made and formatted a 2GB partition). When booted from a floppy, I can transfer files to the SD card and read them. Boot order in the BIOS is set to floppy, CD, hard drive.

I just wondered if anyone had any suggestions before I pull it out and try it in a newer ThinkPad.

fdisk /mbr command perhaps?

[Paul Pennington]

Well I'll be... That worked (in MSDOS 6.22) !

Thanks, Ray

It seems that brand new 2.5" IDE drives are increasingly hard to find, and I am thinking this would be a good solution.

Will you be trying a Windows install?

I'd really be interested in finding out the exact steps to go about making the SD bootable.

I just tried loading Windows 98 (not SE) on the SD card "hard drive". I used an IBM recovery CD for a 385XD. It loaded fine and runs Windows, but the CDROM drive is not showing up, even though Windows loaded from it (!) Device Manager in Control Panel shows a bang in front of the IDE controller. Don't know if this is related to the SD drive or the difference between the ThinkPad models. The 385XD has a 440TX chipset, and this particular 380XD has a 440BX (and a Pentium-II 266).

I have not downloaded any drivers from the Lenovo site yet -- not sure if there are any drivers for the IDE controller.

I'll pursue this and report back what I find, but it will take a while -- very busy right now.

[ieee488]

Please do report back, but from the sound of it, this has a lot of potential.

Hate to go diggin' up old threads, but I had already embarked on this same path when I came across it. I got the same idea with my old 380ed. I used the Hitachi Microdrive Drivers to make the SD card a fixed disk(attached to PCMCIA/IDE adapter) then thru several rounds of attempting to clone the HDD I finally broke down and used XXCLONE and it seemed to do the job fine. But I have the same trouble with the CD disappearing when I mount the SD card adapter in place of the HDD. I'm wondering if it's attached in series with the 4 unused pins on the HDD connector somehow. I have yet to get a good boot out of it though, and I don't know why. It's an 8GB card. I know this thing only ever had an option for as big as 5.1GB HDD's, but I would think it should boot up to at least a 10GB. Got the last BIOS listed, I1ET49WW. Perhaps it is a limitation there. Well, if you're still checking in, how'd you make out in the end? Give up on it? Or anyone else that's been down this road who has 2 cents to chip in, feel free. Being unemployed gives me lot's of time to screw with these foolish ventures. Hey, what the heck. It's runnin' XP pro and a wireless card (albeit rather slow! Never could get WINFLP to load properly.) A little streamlining and some faster access times(SD) and I can just keep it in the kitchen or the bathroom for those odd querys that pop up at strange times and just need to be answered.

No "TP" jokes!

I had no luck getting my 770e to boot from a CF-IDE adapter in place of the 2.5" IDE drive. Didn't try for more than an hour tho.

I've got an sd-ide adapter. It seems to cut the speed of sequential reads down to about 9 or 10 mb/sec, which is slower than some cards, even some cheaper cards IIRC. (If yours doesn't slow the speed, such as when used with a new computer, please post which adapter you have.)

UDMA compliant CF-ide adapters with a little work can hit 45 mb/sec or better, with a card, os, and computer that can handle the speed. USB 2 maxes around 20 I think.

I have booted from my sd-ide the same way as if it were a cf-ide, using a T23's ultrabay 2000. But, it was not seen at all in the ultrabay slim on another TP, forget which model.

Similar for the thin cf-ide adapter with the rounded end where the cf card is, like item 280422595151 on ebay. Nice cheap adapter, but it only works in some ultrabays, and maybe only in some drive bays too?

Long story short: maybe try another adapter type. I've found high compatibility from the Monoprice CF-ide adapter, worked everywhere I put it (tho haven't tried in an old TP), and Addonics CF-ide and especially Addonics CF-Sata adapter, which can even accommodate a card not in fixed mode. Of course, sata not for the oldest Thinkpads, unless maybe you can fit a sata-pata bridge in there.

I'm thinking this bios just can't understand this hardware at boot time. It's weird cuz I can run a HDD test from the setup screen and it says it's fine. No trouble playing with it in diskpart on the PCMCIA adapter after I boot from a CD. But since the CD gets kicked offline when the cards in the IDE slot I can't mess with it there. And it won't boot from floppy when it's there either. Just for grins I put it in an old Toshiba 225cds after I cloned the 98 install off it. Booting from a 98 floppy I can read the card, but it just gives me an invalid disk error when I try to boot from the card. I don't know what the HDD size limits are on these things, but just for the heck of it I think I'll try a 4GB card and see if that does'nt change anything.
