trying to find info about disk drives

[curt larson_1]

I trying to find out some information about some disk drives.

these are in what appears to be a jamacia hass rack. but the part number is C3636A, not C3312A. anyway there are 8 low profile drives in the hot swap trays.

now the trays have no part numbers on them (that would make it too easy), or disk size or df/se coloraization.

I've popped open a few of the trays to see what the disks might be. they are st39173 wc/lc 9G drives.

put one on a differential bus and it didn't work.

so i popped open an A5238a (9G differential drive) and noticed a difference in the adaptor board/personality card that is inside the tray.

the differential drive's has a lot more electronics where the unknown drive's is more straight through.

using the differentials drive's adaptor board the unknown drive works just fine on a differential bus.

so which type of bus does this drives adaptor board work with. the part number of the adaptor borad seems to be C3595-60136.

thinking it might be single ended, i popped the unknown drive into an autoraid that has all se 9G drives without success.

anyone have any suggestions on what kind of drives theses are or what type of bus they could be used on?

Have you looked at partsurfer.hp.com???

yes, I did look at part surfer. and without a hp part number there isn't much I can do. I even called hp about what these disks could possibly be. there weren't able to identify them either. although, they could tell me that the adaptor board was for single ended use.

it did turn out that the drives work just fine on a uw-se bus.

I put toghether some infos related to the mech you have, in the produc number from seagate, the letter D is for differential, so HVD, the N is for SE, may be the following table could help you in identifying the drive.

obviously SE and HVD (called Differential in thepast) are not compatible.

" Some disks using the same string be
either Single-Ended or Differential ", so
look the color of the disk sticker :
Differential = PURPLE
Single-Ended = YELLOW

and specialy for jamaica:

A5238A ST39173WC A5238-69001

that is a Differential one, HVD, you need a HVD HBA to manage it

hope this was useful
