What is the larges (preferably reasonable fast as well) hard drive that can fit in the drive bays of an A3000? So far the highest capacity drive I've found that I know will fit is the Quantum 210M unit.

Drives (see latest Computer Shopper). I hear that there are larger 3 1/2" drives available, but haven't seen one advertised, probably because they're too new. Of course, if you REALLY want size+speed, get a Fujitsu 1.2gig in an external case... has a 5 year warranty, too! (And a price to match.) -- Eric Lee Green (318) 984-1820 P.O.

Dunno wether Quantum has bigger ones but try to get a look on other company's price list. I think, this will help. Cheerio, Peter

I have a MaxStor 340MB. The only problem is that the A3000's ROMs
get impatient waiting for the drive to wind up and I have to do a warm
reboot when it gives me the 2.x floppy/HD and 1.3 floppy/HD menu.
It's a 12ms drive. That's faster than the Amiga-supplied 100MB and
200MB drives that come in the 3000UXB and 3000UXD.

At a rough guess I would say that about 350Meg is the limit for a 3.5" drive (right now anyway). Definitely less than 500 Meg. Micropolis is shipping the largest 5.25" drive right now, about 2.0 Gig. I don't know what the capacities are in *"and larger drives. I don't think any of them are SCSI. I've got another question (to keep you gurus on your toes :->). SCSI has a block address limit of about 1.2 Gig for 512 Byte blocks. If I buy a 2.0 Gig drive and partition the drive into at least two logical drives, do I avoid this problem? This is a serious question. I ordered a SPARC 2 with a pair of 2.0 Gig drives for work and I'm not sure what will happen when we format them. So enlighten me O gurus. Dana Bourgeois @ cup.portal.com

This is a serious question. I ordered >a SPARC 2 with a pair of 2.0 Gig drives for work and I'm not sure what >will happen when we format them. So enlighten me O gurus. The problem is that some disk drivers use the non-extended SCSI commands for block address over 1.2Gb (21 bits address for a 512 byte block) and inadvertantly "wrap-around" and access the lower blocks. This is not an inherit bug in the SCSI drives or protocol, but a bug in the disk drivers. (NOTE: "extended" SCSI commands do not mean "non-standard", just that they have more bits for block addresses and other things.) The drive does nothing with regard to partitioning; only the system software cares about this. Partitioning the drive will ensure you don't access blocks over 1.2Gb, but the faulty drivers still can't access partitions containing blocks at locations over 1.2Gb. In other words, you can still only use 1.2Gb of the 2.0Gb drive. You should ask your disk-driver software vendor. As far as I know, this problem cropped up on DEC VMS and Ultrix disk-drivers, and should be fixed by now. I don't know if SPARCstation SunOS disk-drivers have the same problem. I believe that the AmigaDOS 2.0 scsi.device also had this problem but that it is now also fixed. Fujitsu was recommending you treat 2.0Gb drives as 1.2Gb drives until you receive corrected drivers. ------------------------------------------------------------------------------- The DiskDoctor threatens the crew!

Definitely less than 500 Meg. It's about 500 Meg now (quantum, seagate, others), and Micropolis just announced a 1gig 3.5" drive for 3rd quarter. They expect it to get down to about $1/MB by the 2nd quarter of next year or so. I think Fujitsu is about even with them. >I've got another question (to keep you gurus on your toes :->).

No. It's not the offset to the partition, it's the offset to the device. >I ordered >a SPARC 2 with a pair of 2.0 Gig drives for work and I'm not sure what >will happen when we format them. So enlighten me O gurus. Good luck. A solution: format them as 1024 byte logical blocks.

Some drive support different block sizes, if your disk drive software can handle 1k block sizes then you could format the drive for 1k byte blocks and effectively get an extra address bit.

Just guessing, I would assume that they achieve that capacity in part by having a lot of platters (say 6 to 8 or so) which means that the drive certainly would not be a half height. Almost certainly it will be more than an inch.

The A3000 will not take a standard height drive. It will only accept a half
height drive. However, I have yet to see a 3.5", full height drive.
A point of semantics, but best to be clear about it...

It's possible!), but I thought the 'standard' 3.5" drive was the same height as a half-height 5.25" one. And that the 'half-height' 3.5" drive is not always half the height of the half-height 5.25" ones one should be careful about making assumptions on how many devices can fit in the drive bays.
