Hi guys, how important is the hard drive caddy? my father bought a presario v5000 from a garage sale. i found out that the hard drive caddy was missing and the hard drive in it was broken as well. will a...

OK look any drive, that's is the format, ie: STA or IDE? and that will fit will work, that 320GB will be OK. Simply install the HDD in the bay, and then use a windows installation disk, or similar to format it, just format it as ONE big partition, that should be fine, IF you find that it will not "See" the HDD, then partition it into smaller partitions. However you should be OK. You need to FIRST test to see if the actual PC is OK, try a HDD before you buy a new one, make sure that it is actually working.

What size of hdd is supported by this laptop?

This is part of the A31 specification.

Hard drive features
  • A31 standard 2.5 inch 30GB
  • A31 standard 2.5 inch 40GB
  • A31p standard 2.5 inch 60GB
  • Supports two additional hard drives which can be used concurrently to offer expanded storage
  • S.M.A.R.T technology to issue an alert if a hardware failure is pending
  • ATA Bus Interface
  • 5400 rpm
  • Although you can upgrade the hard drive, it is not designed to be removed and reinserted on a regular basis. Repeated and frequent removal, for purposes other than to upgrade for greater capacity, can cause damage to the system. The Ultrabay 2000 hard drive adapter is designed to provide this flexibility with a second hard drive in the Ultrabay 2000

I have windows vista just had a new hard drive installed the data off the old drive has been put onto an hdd caddy how do I load it back onto the new hard drive of my computer, the caddy is a plug in via a...

When you insert the usb cable from the caddy into a USB port on your notebook, Vista will automatically recognize it and open a dialog box. Choose to view files and folders.

Open another Window using Explorer and resize it so you can see the contents of your C: drive.

Then simply drag your files and folders from the caddy to the C: drive where you want them.

Remember that transferring program files will NOT help you as many of the files needed to run a program are located in other folders such as yours Windows directory. You will need to reinstall any software you wish to use.

This method is strictly for data transfer, as an example all your pictures, documents, spreadsheets, etc.

I have a Compaq presario V2000. Right now I have 60gig internal hard drive. Is there a max internal hardrive I should purchase? I can buy up to 250 gigs? How much would you recommend I purhcase?

Usually, the more storage the better. You can go up to 260 gig total with a primary 100 gig drive and a secondary 160 gig drive. Note that with the extra drive, the unit will use more power so think about that first.

Removing the hdd in my toshiba 1135-s125

OK, This is a big undertaking if you are completely new.

1st, if you can get a static guard wrist band - great!
2nd You will be dealing with plenty of screws so keep track

In Toshiba notebooks most screws are marked. Here are some examples:
F4 - flat-head screw 4mm long
B6 - button-head screw 6mm long
F16 - flat-head screw 16mm long
B8 - button-head screw 8mm long


I have .a Toshiba Satellite 1135-S155. It should be a similar configuration, same family/1135-S1xx series.

You will have to remove a total of 9 Phillips screws.

Place the underside of the PC up.
Disconnect all power, cables and Battery from Laptop
The first screw is located just under the Toshiba Serial Number / Bar codes, just above where the DVD/CD-ROM combo drive is located.
Mine is labeled (F5). Unscrew it and place in a safe place.
Pull DVD/CD-ROM combo drive out it is an assembly.

The Hard Drive is located under the DVD/CD-ROM combo drive.
The Hard Disk Drive (HDD) is enclosed within a caddy containing the remaining eight screws.

There are four screws holding the caddy rails to the Laptop and four screws holding the rails, caddy and Hard Drive as an assembly.
Unscrew and place in a safe place/ container they are small. Disassemble the HDD from caddy assembly; place your HD in the caddy and reassembly.

Here is another Toshiba HDD access that is slightly more
straightforward than my 1135 series
So you get an idea of where a HDD is visually:


Above is a photo of the Battery sliding out

Below is the Hard Drive Removal


I hope this gives you an idea of how to go about it for your
particular Laptop

If you need further assistance, let me know

2nd hdd

both hard drives will need to be jumpered to a master and a slave or both have to be jumpered to cable select. normally the jumper setting are either on the label of the drives or are marked on the bottom of the drives near the jumper drives. if the setting are not shown find the drive type, model and capacity then do a google search for the drive "select the factory manufacture link" and search their site for the jumper setting of the type drive you have.
