Just add in a new HD in PC. BIOS can detect the 2nd HD or slave but Window can't? Open Window Disk Management only see Disk 0 but can't see Disk 1.
New HD Pin jumper set to SL(slave).
Any good advice.
Thanks

Summary and focused next steps for the scenario described by (BIOS sees the second drive but reports CHS/size = 0 and Windows Disk Management only shows Disk 0). correctly suggested checking jumpers and cables; the following clarifies likely causes and gives targeted checks that go beyond the replies already posted.

Recommended hardware checks (in order)

  1. Swap the Molex power lead: move the power connector from the known-good drive to the suspect drive. A failing power rail or bad connector can let a platter spin briefly but fail under load.
  2. Replace the 40-pin IDE cable with a known-good 80-conductor cable and confirm the suspect drive sits on the cable end when set as Master. If the motherboard/cable uses Cable Select, try setting both drives to CS and use a proper CS-wired cable.
  3. Test the drive as the only device on the cable with its jumper set to Master and on the cable end. If the BIOS still reports CHS/size = 0 with the drive alone, the problem is almost certainly the drive electronics (or an incompatibility), not Windows.
  4. If available, try the drive in another PC or via a USB-to-IDE adapter. If the behavior follows the drive, treat it as defective.

BIOS and capacity considerations

  • A drive that reports zero CHS in BIOS usually indicates hardware/firmware failure or a BIOS translation problem (older BIOSes and very large drives can behave oddly). If the drive is large, checking for a BIOS update on the motherboard can be worthwhile before advanced translation tricks.

Windows-side checks (only after BIOS shows correct model/size)

  • Use diskmgmt.msc -> Action -> Rescan Disks and check Device Manager under Disk drives. From a command prompt: run diskpart then list disk to confirm whether Windows sees the device at a low level. If the disk appears uninitialized, initializing/partitioning is required (this will erase data).

Likely outcomes

  • If the drive works on another system, suspect cable/motherboard. If it shows CHS=0 elsewhere, the drive is failing and should be replaced/RMAed. Avoid repeated power cycles on a failing drive to preserve data if recovery is needed.

Futher detail

When startup can detect the 2n HD. But after few min it show Pri Slave HDD Error Press F1 to resume. Check the jumper and IDE connector is correct.

Do as it says: Check the jumper settings. The settings are indicated on the drive itself. I know ppl who inadvertently set both devices as master/slave. Also, check for loose connections on the drives and the motherboard.

Jumper is on right pin. 1st HD set to Master(MS) 2nd HD Slave(SV). Ribbon is also correct, the end is Master and the middle is Slave. In BIOS both HD can be detected but in the Window Disk Management only can detect one disk only that was Disk 0.
But in the BIOS 2nd HD(Slave), set to Auto can detect the HD but the cannot see any cylinder, sector and head, so total memory is 0.
What wrong ?
Thanks for the reply

Could be a bad HD as it can't see the cylinder, head and sector. Try configuring these parameters manually and see if that helps. Next, disconnect the old (working) HD and only connect the new one. See if the CHS parameters are bow detected. If they are, you have a bad data cable. Also, check the new HD on another computer. If it doesn't work there, the HD is bad.

When you connect the HD, can you feel a very slight vibration and hear the disk spinning (you need to listen very closely for this)?
