Hard Disk Quantum QML20000LD-A

I need to repair a Quantum hard disk (QML20000LD-A) with some important data on it. I have found the electronic demaged, one smd resistor was broken and lost, so I'd need to know the value of this resistor to replace it. Where can I find some electronic schematics of this hard disk.

Re: Hard Disk Quantum QML20000LD-A

Hi, may I offer an alternative solution? You may want to try and replace the entire PCB assembly rather than repair. I would assume that the Quantum QML20000LD-A is a few years old and so many of the same brand/model would be lying around computer repair shops. Even if defective, these drives can be: 1) direct parts source; and 2) remove/use the entire board. You can even find this kind of HD from old CPUs (166-550 MHZ.) I believe you can get them relatively cheap and faster. Hope this somewhat helps. Cheers.

Its a very old hard disk, few things you can do,

1.. Get into your pc's bios and see if 32bit access is enabled for your disk, if not enable it, reboot.
2.. Goto control panel > device manager , double click on your IDE controller and check had disk status, if is on PIO mode or UDMA , must be at UDMA. Set it if not.

Not a good sign. You will need to pay to have the data recovered if you need it. Otherwise, plan on getting a new disk and reinstall Windows.

The board got burn on one of the chip

You have two separate questions.

1. I have a Quantum hard drive which got a burn on one of it chip on the green part it is from an IBM aptiva 95 all of my data is on it .

Unless you can find an _identical_ hard-drive, and disconnect the electronics from that disk-drive, and then connect the electronics to your hard-drive, your data is "lost". Or, find a "Data Recovery Service" -- for a large fee, they will repair your disk-drive, just long enough to burn a bunch of CD/DVD disks to hold all the "data".

2. I have onother that I have accendentally delete one of the partition which is the C drive

Download the "Partition Tool Editor" by the PowerQuest PartitionMagic people (now owned by Symantec):

Unzip the file, and, while the "accident-prone" disk is connected ot your computer, run 'PTEDIT.EXE' to change the Partition Boot Table, to "undelete" the partition. It's *NOT* a tool for "novices" -- think carefully before making any changes to the Partition Table.

Does the Intel 82801 chipset recognize the full capacity of a quantum 20gb hard drive?

Yes it should recognize such small drive. Note that the partitions on the drive will affect how big drives are shown.

If the drive is partitioned into two 10GB parts then you should have C: 10GB and D: 10GB

Note that if the drive is partitioned not to use the full capasity then the capasity it is partitioned to will be shown instead.

Also Note that computer hard drives the capasity is not accurate presentation of the GB available. it will always be somewhat less than the reported size, for example 1000GB disk is shown as 931.50GB
500GB disk is shown as 465.76GB and so on.
