I have installed a 3.5” Seagate Barracuda 7200.8 300GB hard drive into a Sabrent ECS-U35K external enclosure. The Seagate hard drive serial number is 4NF02GEA and firmware 3.03. The jumper is set to "Master." I am connecting to my CPU with a USB 2.0 cable. I am running Windows Vista. In the "Disk Management" menu the external drive is listed as Disk 6, shows a single partition, 297.46 GB NTFS, Healthy (Active, Primary Partition). There are diagonal lines running through the Disk Management information box. However, under the Disk Management “Volume” column, the drive is named, but shows only 128.00 GB “Capacity” of which 123.82 GB is “Free Space.” Also, in the "Computer" menu, the external drive shows only "123 GB free of 127 GB." I have around 70 GB of data on the external drive that I cannot access and much of the external drive capacity is inaccessible. The Seagate tech reps feel I may have a problem with the IDE to USB 2.0 conversion, causing a communication limitation between the external drive and the CPU. Seagate also states I cannot run their DiscWizard software on an external drive. Any help or advice you could provide would be greatly appreciated. Thanks
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.

the CLJ , cylinder drive limit jumper must be set right, 137GB is the limit on IDE PATA relic drives.
what you did wrong I guess is move the drive from a real PC direct to PATA port on its mobo.
to the external driive, this is not going work well.
what to do is backup your data first. or do this
1: directly install the drive in a relic PATA PC. set CLJ jumper to 137GB limit.
2: using partitioning tools, (not vista) use I Aomei partition tools. (or the like kind)
3: erase the whole drive. all those old ugly wrong partitions you saw are gone.
4: format it to Fat32 or NTFS at 137GB,
5 move it to the relic U35K PATA external drive now.
6: the 12vdc 2amp power pack must be connected or it WILL FAIL.
7: USB plugged in now.
8: PC now sees then new driver and new formatted drive at 137GB.
learn to use batter backup tools. and modern sata is that tool, 2009 we had 8 long years of sata drive made.
do not use PATA drives after year 2001. you are 8 years too late. and are JUNK. that old
no hdd lasts for 8 years, none. buy modern drives to backup not old and never PATA forget it existed is best.
the real drive name is NOT 7200.8 but is
ST3300831A
true name this is.
quote your seagate manual (LL = Legacy Loon-icy) PATA pain. PP.
Some older computers may “hang” at startup if their BIOS detects a disc drive with a capacity greater than 32Gbytes.
This limits the drive’s capacity to 32 Gbytes when the alternate capacity jumper is used.
To access the full capacity of the drive, you can:• Update the BIOS• Use third-party software such as DiscWizard™ or Disk Manager•
Use a third-party host adapterFor drives with capacities greater than 32 Gbytes, the alternate capacity jumper changes the total available LBA sectors to 32 Gbytes to solve issues with some BIOS during power on. The ATA Set Features subcom-mand “F1H Report Full Capacity Available” causes Identify Data words 60 and 61 to report the full capacity.See Section 4.1.3 on page 33 for more details on the Set Features command.Windows XP, Windows Me, Windows 98 or newer versions are needed to support drives with capacitiesgreater than 32 Gbytes.
bingo still there, for 14 years.https://www.seagate.com/files/staticfile...
there is 1 more problem at 137GB, limits. back then, per the wiki. end, legacy coverage now.
do not forget the ECS-U35K chip inside (USB to PATA) will have limits too, on cylinder translation.
and my be a horror to use, and risk huge data loss. you.
better yet this guy published all PATA drive horrors and limits here.

a real legacy GEM, There
32 GB Limitation - June 1999. (ABOVE)
64 GB Limitation
137 GB (128 GB binary) Limitation - October 29, 2001.(YOU) SEAGATE LINKS LOST. SADLY.
2.2 terabytes (2,200 gigabytes).(32bit OS limited) vista 32bit. too. but your CHIP and driver are your limits.
ETC.
he moved a none blank, hdd from used PC to the external chassis.
this was the grave error done.
start with erased only, first then format it only inside the usb chassis.
