How to connect a IDE-to-USB cable to a 2.5 inch drive?

I have Sabrent IDE-to-USB cable, model usb-2535, and I would like to connect it with a 2.5 inch drive. I have 2 questions: 1. How do I plug in the drive correctly? There is no indication of what's the right direction. I can plug in having the jumper pins on either the left or right side, but I think there is only one right way. 2. How does the drive get its power? If I plug in a 3.5 inch drive, I can use the power supply that comes with the cable. But there is no place to plug in the external power supply for the 2.5 inch drive. Is the voltage from the USB port enough for the 2.5 inch drive?

1) You will do no harm by reversing the connector, but the PC won't "see" the drive at that point (if your drive has an activity LED it will be permanently ON if the cable is reversed) 2) Most times the USB will have enough power to drive the HD all by itself, but if you are going through a hub that may not be the case. In that situation, plug the device directly into a USB port on the PC.

Well, I've got the same product and fugured that 2.5" drives work
OK with it only if 40 to 44 pin adapter with power connector used.
The 44 pin connector built into USB-2535 controller is useless.
Also connection steps should be followed meticulously:
Step 1: Connect USB-2535 adapter to a HD (3.5 or 2.5 with 40/44 pin adapter) -red LED will be "ON"
Step 2: Connect low side of the power supply to HD.
Step 3: Plug power cord into el. outlet.
Computer will see your HD as USB Mass Storage Device.

Reduced Hard Drive Capacity with Internal to External Kit

Problem can be tricky.. though i offer my two cents.

1. some BIOS have upper limit of hard disk capacity. check that out. try connecting IDE device to IDE connector in same comp and see if it is being detected properly.

2. seagate guys are true .. IDE to usb conversion can be tricky ... a lot depends on card convertor.

my advice would be if you have precious data on it ... first take a backup of it, if possible connecting the disk to nomal ide connector.

Sabrent 5in1 USB-DSC5 doesn't recognize 2.5" WD hard drive

I have had a different problem with this product. But, I have read many postings on its problems. It seems that for certain hard drives the jumper should be set for something other than 'master', either CS or no jumper at all. This seems to be true for only certain HD's.

Hope this helps.

Sabrent 5in1 USB-DSC5 USB2.0 to SATA & IDE cables HDD not in Windows Explorer

There shouldn't be any problem accessing FAT32 drives of that size.

Check your disk management (right-click "my computer", hit "manage" and then click on the "disk management")

It should tell you what kind of formatting the disk is, and what the drive-letter is.

If it shows as being FAT32, then you're fine. If it doesn't, the FAT has been corrupted and may require a disk rescue or some kind of disk fixing utility.

Assuming it shows the partition as healthy and FAT32, but it doesn't have a drive-letter, right-click on it and "change driveletter". Pick a letter and hit OK. It should now show up!

but the new pc doesn't recognize the drive and, obvously doesn't assign a
drive letter to it.

i tried reversing the cable, changing the hard drive, using different usb port,
re-booting. still doesn't see the drive.

1. jumper settings are correct

2 i use vista, not win 2000 or xp

2 harddrive is old, from old computer

vista doesn't have 'my computer'
i can find manage disk management
can't right click becausse the drive isn't there

how do i change the hdd settings from dynamic to basic if i can't see the drive?

answers to your questions":

1. i'm running windows vista home

2 size of drive... it's old and probably fat(32) under 1g

3 i cycled through the settings
j8 jumper settings
slave, master, & single

no settings work

4. yes i heard the drive spin up

5 the led is red, not green

thx again for your efforts
