n91 hard drive unavilable wat is problem help

[amps_jas]

Device hangs when booting
Cause:
- Corrupt HDD
- Defective HDD
- Defective device
- HDD sticking

Cannot access the HDD
Cause:
- Battery cover not in place
- Magnet missing from battery cover
- Damaged HDD
- Corrupt data on HDD
- Poor interconnect between HDD and PWB

HDD Corrupt
Cause:
- Data installed from factory, that was corrupted
- Applications installed on the HDD by user, not compatible
S60 applications that are not version 3.0 (previous versions) are not compatible with N91.
- Application install process to the HDD by user, that are not compatible
If an application was copied from another device to a PC and then onto the
HDD via mass storage, this will corrupt the HDD. Applications that worked in
non-S60 3.0 devices will not work in the N91 or other S60 3.0 devices
because of binary incompatability. Example: an application that works in a
N70 or 6630 will not work in the N91 or N71. If an application was
downloaded from the MMC of these devices and transferred (drag and Drop)
into the N91, this would corrupt the HDD and the HDD would have to be
formatted to function again.
The N91, on startup, will see applications that were copied from the PC to
the HDD. It will try to install these applications; this will lock the HDD and
not allow access. This problem, with early sw (version 1.0), was only able to be repaired by formatting the HDD with Phoenix, because the USB connection could not access the HDD.
Also, if the customer took a backup of a corrupted HDD image, when they
restore this image to the device it will have the same fault.
If an application was interrupted when it was being installed on the HDD by
a power cycle.
Applications have to be allowed to install uninterrupted

Slow Accessing Applications
Causes:

SMS, MMS, Themes, and some applications if they are loaded onto the HDD, will cause slow access times. All these items should be loaded onto the devices internal memory and not the HDD.

Quick Test tips
If the device will not boot:
- Restart the device with the battery cover removed
If the device boots then there is a HDD issue.

If the device boots but can not see the HDD
- Make sure the battery cover is in place.
- Check that there is a magnet in the B-Cover
Use a metal object (a paper clip works) and see if it sticks to the lower
right side of the device (opposite to the USB connector)
If it does not stick replace the b-cover with a good b-cover. Retest.

Testing
There are different tools available to test and repair the HDD. They are available from the User Interface (UI), through the “Mass Storage” USB selection when connected to a PC and through Phoenix test software. Depending on the level of corruption on the device, this will limit which
tools can be used. If the HDD is not accessible through the UI or the PC, then the last chance to format the HDD is through Phoenix.

sir urgent help only available toll hwk

[amps_jas]

or try this sir without using any box:

1. TAKE OFF BACK COVER. reboot phone by holding the (pen-key), the phone will boot as safemode. (it looks no different from normal mode)

2. go to setting--> harddisk (now you will still see "harddisk is not available")

3. PUT BACK COVER ON (do this slowly). then the phone will work very slow BUT THE PHONE IS NOT HANG.

4. you have to be patient, and press option key, and wait for phone responds, it normally takes from 2mins to 5 mins (some phones responds fast, some phones responds slower, depands how it reads harddisk)

5. after option menu comes up, choose harddisk to format (formatting takes about 15 mins or more, be patient, wait until finished, after formatting harddisk, every thing will work ok again)

br

tnx goes to sir amps:D

[topman]

thanks amps_jas

if the problem persist, then maybe its a hardware problem...

there are couple of problem that can lead to HDD unavailable...
The general data path is from OMAP (D4800) - HDD Level Shifter (N5200) - ESD protector (Z5200) - HDD connector (X5200)- then harddisk.
any component that fails along these path could lead to HDD unavailable.

Power supply is a possible problem too, L5200 and N5205 are the main components.

Look at page 6 of this N91 Schema (http://www.yasikgsm.narod.ru/files/nokia/N91_schematics.rar)
