ADS USB 2.0 Drive Kit works w 40 gig/ not with 100

[GrannyK]

Both drives WDigital. Both work on win98se desktop system, but when installed in the USB 2.0 Drive Kit, the 100 gig will not install and work.

Put the 40gig into the kit, instantly loads and is visible on the xp laptop, and on the win98 desktop system.

Both systems using Fat32, both drives partitioned as extended, since I am using them for storage.

I am very confused, since, as I said, the 40 gig and the 100 gig both work perfectly when connected as a 3rd drive on the desktop running Win98

I would really rather use the 100 gig drive in the drive kit, since I can then use it with the laptop, which has a smaller (30 gig) hard drive.

Any help appreciated.

Maybe the limitation is in the external drive case. What brand is it or where did it come from? Do you have USB 2.0 ports on the computer?

Thanks for taking the time to reply

The kit is an ADS Technology USB 2.0 Drive Kit - apparently it should handle the 100 gig drive no problem

The laptop has a usb2 pcmcia card (but I did try it on the regular usb port as well) and the desktop system has only the lower speed usb ports..

I missed a point, do you have the drive jumpered as Master or Master/Single? [May also not need a jumper at all to be Master as some WDC Caviar drives were.] My cases can't handle a drive jumpered as Slave. Check the label on the drive.

Sorry, I too forgot to mention that the WD has to be run with jumper off as a single in a drive enclosure...

(when the 100 gig wouldn't work like that, I jumpered it, 'just in case' ;o)... and still no joy.

The only other differences in the drives that I can think of, other than the size, is that the 40 gig began life as a primary drive on a system, fdisked, partitioned and formatted with DOS, then had the partitions changed using Partition Magic (with the data still in place)whereas the 100 gig was used as a secondary drive from the start, also fdisked, formatted and set up as 'all extended', then the partitions created from DOS.

When I look at the partition structure with PMagic, all looks identical.... (guess I was thinking that maybe there was a 'phantom' lurking there which would not let the 100 gig function as a master) .... or something ;o)

If I can find space on some other system for all that data/stuff/junk, I may try starting over with the 100 gig, and try it clean....

Any ideas would be appreciated

Would be nice to see a Drive Kit FAQ - I have searched all over the net for a solution to this, and have found a couple of people with similar problems, but they had asked their questions a while back, and no solutions were ever posted.

Thanks again

My wife's Win98SE has a Mobile Rack in it. I put a drive in the cartridge/cassette, put it in the Rack, boot up and can use fdisk, and format on it. Once that is done I remove the drive and put it in the external case. I keep all my externals at FAT32 to keep them compatible with other computers I run across. Win98/98SE did need an updated fdisk from Microsoft to recognize larger-than-64GB drives properly, even though the BIOS does.
